As you continue your journey of developing and bringing a new product to the market, you have a series of decisions to make when it comes to prototyping — whether you're going to launch a hardware or a software product, or the combination of both — you need to have a prototype made.

Before you begin, there are a number of things to consider. In an article for InnovationMap last week, I looked at major choice points and their implications that will help you navigate the process in the most efficient way.

After you successfully laid the foundation for the development process and got you CAD models ready, you arrive at the next choice. Prior to making a prototype of your invention you need to decide what type of prototype you're going to build. Whether you're making it yourself or hiring a rapid prototyping company, you need to know the purpose your prototype will fulfil because it will help to select proper methods, techniques, and materials for building. With that in mind, let's go through the types of prototypes and purposes behind building them.

Types of Prototypes

Mockup

This type is usually used as a simple representation of your product idea, to gauge physical dimensions and see its rough look. It's especially useful for making physical models of complex and large products without investing a significant amount from the start. Mockup is perfect for initial market research and various types of early testing.

Proof of concept

This type of prototype is built when you need to validate your idea and prove that it can be realized. It comes in handy when approaching potential partners and investors.

Functional prototype

This kind of prototype is also called a "looks- and works-like" model because it has both technical and visual features of the product presented. It is used for testing product's functionality, conducting consumer surveys, and fundraising campaigns.

Pre-production prototype

This is the most complex type that is made at the latest stage of product development. It's used for ergonomics, manufacturability, and material testing, as well as to minimize risks of defects during manufacturing. This is a model that manufacturers use to produce the final product.

Choosing to Partner with Prototyping Company

It's important to note that prototyping is an iterative process. It is a fusion of art and science that helps you to uncover the full potential of your product, which in turn increases its chances for market success. Therefore, you will likely go through several types of prototypes, with each kind usually requiring a few versions to achieve the parameters you set for the model.

And this process also requires help of a company that builds prototypes or of a professional product development team. You can start looking for the one after you made your first mockup or proof of concept. It is recommended because creating more complex prototypes implies the use of sophisticated equipment, sourcing of materials and components that could be too expensive or complicated to do without an established network of suppliers. Plus, skills and experience play a huge role in creating quality prototypes. Taking all three factors – equipment, experience and skills - into account, it's smart to outsource your prototyping needs to a professional company.

This article is a follow up article to my post from last week. I have also previously contributed to guest columns on the following:

Lessons in prototyping: Choosing the right approach to product development

guest column

When embarking on the journey of developing and bringing a new product to the market, you as an inventor have to consider a multitude of aspects that add to the overall market success of your final product. And prototyping is one of the key product development stages that helps you achieve that.

Whether you're going to launch a hardware or a software product, or the combination of both — you need to have a prototype made. First, it allows you to validate your idea and see if it's worth investing time and money into. Second, it creates opportunities for product improvement, detection and elimination of design flaws, and cost reduction, especially during manufacturing.

Therefore, you will need to make a set of choices before you actually build a prototype to ensure that it results in a viable, cost-effective, and quality market-ready product. Let's look at major choice points and their implications that will help you navigate the process in the most efficient way.

To begin, let's look at the various options you have.

The success of any process lies in its foundation. Hence, before anything else you need to decide on the product development approach you're going to follow. Some inexperienced inventors, for instance, choose to go from product idea straight to having a prototype made. They skip three initial steps that are crucial for building a sound road map of the development process and creating a product with a maximum market potential.

In most cases, those inventors end up coming to companies that build prototypes to start from scratch. Usually, it's because they hit a dead end with their prototype or a product was manufactured with many defects. The latter is always a result of improperly optimized pre-production prototype, if optimized at all.

The extensive experience of our product development team shows that a methodological approach to the entire process, prototyping in particular, yields the most effective results. That's why we always recommend it to those inventors who choose to DIY their prototype. If you're one of them, here is a short version of the approach with steps it implies that you can use prior to prototyping. You can find the in-depth version here.

1. Product discovery

To set the path for the development of your idea you need to identify your product's strengths, weaknesses, opportunities, and threats. In other words, you need to conduct a SWOT analysis, which will help you learn about:

  • intellectual property opportunities
  • your competition and target market
  • features your product should have
  • time and cost of your idea development.

2. Concept design

Based on the results of the SWOT analysis, you can establish the road map of the development of your product and get to creating a concept or industrial design. Concept design is a virtual representation of your idea translated into 2D renderings and 3D CAD models that show you a rough look and functions your product will have. These should be built in accordance with preferences of your target audience to ensure the product's market fit. Concept design is usually made by a professional Industrial Designer. But if you have a basic knowledge of how to use industrial design software applications, then you can make it yourself.

3. Market and prior art research 

Another important step before prototyping is gathering and analyzing feedback from potential consumers. This is done through market research. With a concept design developed, you can conduct focus groups and consumer surveys to understand if the audience likes your idea. The information you get will give you more opportunities to improve your idea and add necessary changes to the design before prototyping, thus reducing the cost of the process and increasing market potential.

Prior Art Search, or research of existing patents, provides some of the benefits as market research. But its main purpose is to identify similar product ideas that have already been patented, so that you can make your product stand out by adding unique features to the design, as well as avoid a conflict of patent rights.

In a follow up article next week, we will discuss more decisions you must make during the prototype process. I have also previously contributed to guest columns on the following:

These are the risks and rewards of prototyping, according to Houston expert

Guest column

We live in a digital world. Music, movies, and even family photos have become primarily digital. Computer software offers us a range of comfort and efficiency and has become part of our daily routine. So, why would anyone want to build a career around physical product development?

Simple, almost every software product or next big thing relies on a well-executed physical product development project. Apps need a place to run, games need a console to be played, and pictures need a camera to be taken.

Physical product development means dreaming of something that does not yet exist and solves an existing problem. It means taking an intangible idea and making it into a physical item that people can see, touch, and use.

The journey from ideation to creation, and then manufacturing can be difficult, but rewarding. By understanding the process, you'll find that not only is your inspiration worth pursuing, but it may be one of the most fulfilling things you will ever do.

From inspiration to perspiration

Every product development project begins with a vision, the identification of a problem and a solution for that problem. That initial spark of inspiration is what drives the entire project.

Look for a problem that hasn't been solved and solve that problem, or try the reverse. Think of a product idea, and then work backwards to find the need. Regardless, one cannot be successful without the other.

Projects require this problem, or need, because it embodies the product's target market. A product idea without a well-defined need has no reason to exist, and if it did, it would be downright perplexing.

Once you identify your need and idea, start your research.

Test the validity of your idea. How much of a market exists for your problem-solving miracle? Send out surveys, look at various markets, conduct data analyses, and generally, do everything in your power to ensure that your product should be made.

Then, start making something.

From concept to reality

The design, prototype and manufacturing stages are what bring your inspiration closer to reality. Turning it into a concrete product means letting go, and that can be scary.

Initial concept designs can be done in a variety of different ways. Detailed sketches and blueprints could be drawn up, or CAD drawings can be created. This concept design can help you explain your idea to others, including partners and investors. What works even better, though, are prototypes.

A prototype is a preliminary model of your product that can help you determine the feasibility of different aspects of your design. You can make a functional prototype, which acts as a proof-of-concept for your idea, or you may create aesthetic prototypes that will test the look and feel of your product.

Once you nail down the ideal appearance and physicality of your product, you will need to combine the two disciplines as seamlessly as possible. This performance prototype will effectively demo your final product.

Finally, you can prepare your product for production. Designing for manufacturability (DFM) means ensuring that your product can be made efficiently and cost-effectively. DFM allows you to mistake-proof your product by choosing the best manufacturing materials and methods, while keeping in mind the appropriate regulations for your desired market.

From nothing into something

The product development process often changes. Trends like crowdsourcing and innovative fast-to-market solutions constantly upend the process and make it new again. Some automakers, for example, want to innovate the design process using existing customer data — similar to how companies like Microsoft and Apple create iterative versions of their software product development projects.

Getting your product to market can be tough, but certain approaches can ease the burden. Create a simpler product. Fail fast and fail cheap with lean development, meaning limit your risk to maximize your return. Also, never underestimate the importance of customer feedback and intellectual property protection throughout the process.

With that said, invest in yourself and your inspiration, and you will avoid that nagging what if-mentality that drives regret. Great reward always requires risk, but there are also ways to invest smarter. Use available resources and give your dream the best chance for success.

Making a product that is worth further investing in, one that customers will want to buy, requires several prototypes, sometimes tens of prototypes to prove the concept and perfect your idea. Photo courtesy of OKGlobal

Houston expert shares why prototyping is so important to startups

guest column

Rarely in life is anything perfect on the first attempt. Writers write drafts that are proofed and edited. Musicians practice over and over, and athletes train for years to perfect their skills before becoming pros. So, it only makes sense that a product developer would develop a prototype before manufacturing their products.

But why? Why can't a perfectly designed product go straight from CAD to production? In reality, making a product that is worth further investing in, one that customers will want to buy, requires several prototypes, sometimes tens of prototypes to prove the concept and perfect your idea. Success comes through practice, just like with the musicians and the athletes.

Defining "prototype"

The word prototype derives from the Greek word meaning, "primitive form." It's an early sample or model of a product built to test a concept or process. Understanding that a prototype, by definition, is an early form of your final product, know that there is often a compromise between your prototype and the final product design. Differences in materials, manufacturing processes and design may create a slightly different look and feel of your prototype.

A full design build is expensive, and it can be time-consuming, so before manufacturing, we create a prototype. This allows you to look for any flaws and problems, figure out solutions, then rebuild with the updates. The process may repeat multiple times. Rapid prototyping is often used for your initial prototype, allowing you to inexpensively build and test the parts of the design that are most likely to be flawed, solving issues on the front end, before you make the full product.

This necessary step is needed to progress with your product development and take you further toward the commercialization and marketing of your product.

Why prototype?

Prototyping allows you to learn about the product, the design, and the functionality. By doing repetitive prototyping, you eliminate the guesswork and base your decisions on actual data and facts. Don't ever guess. Just learn. Just prototype.

Market Testing
It allows you to put a product in front of your consumers, get their opinion, and make changes based on how the consumer uses the prototype.

Save Money
You get to save money on initial product testing, by letting consumers test the product the way they would use it in real life.

Make Improvements
Prototyping gives you the opportunity to make improvements before putting your product into the market. You can see where/if your idea is flawed and flush it out before you manufacture products that won't sell.

Sales Forecasting
This is a difficult enough task as it is, but when you have a new product, it's hard to predict how it will fare against other products in the market. By watching how consumers use the prototype, and by seeing it work against other products, you will begin to understand the sales cycle for that product, allowing you to start your forecasting.

Product designers cannot predict how a consumer will react to a new product, so they release several prototypes, and gather feedback, switching up the products until they find what works for the consumer. When the product went to manufacturing, and finally to market, it was almost guaranteed to be a success—an unintended use for prototyping, and yet one of its best uses.

Designers realize that what looks good on paper isn't always what the end-user is going to want. By getting an inexpensive prototype in front of consumers, designers have been able to get quick feedback, adjust the product, and create a winning product.

When it doubt, prototype it out

The beauty of prototyping is that each prototype interaction opens new opportunities to improve your product. In all reality, you will need more than one prototype to develop a truly valuable product. Product development can get bogged down in meetings, where the product is analyzed, and guesses are made as to "the best way," but by getting to the rapid prototype stage, you can skip some of that guesswork and replace it with real information from the customers.

Houston brain health co. secures $6.5M for rare disease study

neuro funding

Houston-based Goldenrod Therapeutics, part of Fannin Partners' portfolio, has announced the initial close of a $6.5 million series seed preferred stock round.

The round was led by Ataxia Ventures and an affiliate of Fannin, according to a news release.

Goldenrod Therapeutics plans to use the funding to support manufacturing, formulation optimization, IND-enabling studies and a Phase I study of its drug to treat brain inflammation, known as 11h.

The study will consider how 11h, which blocks the enzyme PDE4, could treat Friedreich’s ataxia (FA), a rare genetic disease that affects movement, speech and balance. To date, other PDE4 inhibitors have proven to regulate neuroinflammation and neuronal signaling, but have had adverse gastrointestinal side effects or have not reached enough of the central nervous system, according to Goldenrod.

The company says its 11h is expected to have "broad applicability" with limited emetric side effects.

“Our 11h program is a next-generation, orally bioavailable, brain-penetrant PDE4 inhibitor, where researchers overcame longstanding limitations associated with earlier PDE4 inhibitors," Dr. Dev Chatterjee, CEO of Goldenrod, said in the news release. "We believe this creates the potential for a best-in-class therapy for Friedreich’s Ataxia and a potential foundation for development across multiple neurodegenerative and neuroinflammatory disorders.”

11h was first developed at the University of Nebraska Medical Center (UNeMed). Houston-based Fannin Partners in-licensed the product 2020 and landed SBIR Phase I funding to support its initial development for opioid use disorder soon after.

Goldenrod has also received funding to study 11h's effectiveness for multiple sclerosis, methamphetamine addiction and cocaine addiction.

Goldenrod says it is developing 11h to target a variety of neurological and inflammatory conditions, including Alzheimer's disease, multiple sclerosis, ALS, substance use disorders, Batten disease, pain and traumatic brain injury.

Elon Musk's SpaceX is about to make its debut on Wall Street

Money Moves

Elon Musk's rocket company SpaceX will make its debut on Wall Street Friday, June 12, and both institutional and retail investors are expected to gobble up the 555.6 million shares going up for sale at $135 apiece. Musk, already the world's richest man, could become its first trillionaire.

SpaceX is likely to become the biggest IPO ever, with proceeds of around $75 billion. SpaceX hopes to become the first company to send people to Mars. In fact, part of Musk’s future compensation depends on SpaceX eventually establishing a colony of at least 1 million people on the red planet.

Why SpaceX is going public now

In a video conference on Musk's social media platform X, he told JPMorgan CEO Jamie Dimon that people have suggested for the last 10 years that he take SpaceX public. He's doing it now because the company plans to put 100,000 next-generation Starlink satellites into orbit. Deploying AI data centers in space is a “massive new growth base and you need capital for that,” he said.

Going public provides access to the capital that SpaceX needs. But it also exposes it to more scrutiny from shareholders and more regulatory oversight. That includes filing quarterly financial reports, which critics say incentivizes short-term thinking over longer-term planning and creates unnecessary costs for a company. Securities regulators are currently soliciting public comment on a proposal to require public companies to file the financial reports only twice every year.

How the IPO impacts the company

Musk will hold the majority of a special class of shares, giving him control over decisions related to company strategy, finances and personnel. On the latter, because of his ownership of most of these Class B shares, the only person who can fire Musk as CEO is Musk.

The company credits Musk with being the “driving force” behind its growth, innovation and success. But what happens if Musk is no longer in the picture? SpaceX warns that the loss of Musk could disrupt its ability to execute its strategy as well as hurt its “reputation and relationships with customers, partners and other stakeholders.”

The company also warns that finding a replacement with the same skills and experience as Musk would be time-consuming, if not nearly impossible. As Wedbush Securities analyst Dan Ives wrote Wednesday, “At the end of the day Musk is SpaceX and SpaceX is Musk.”

What could make or break SpaceX

Currently in the test phase, the gigantic reusable Starship rocket is key to SpaceX realizing Musk's ambitions. Much of the commercial space business hinges on SpaceX developing Starship’s capability to be fully reusable and hearty enough for a quick turnaround between flights. If that doesn't happen, SpaceX warns that putting data centers and satellites in space will take longer and cost more money, meaning it risks customers bailing on the company.

Analysts say that by pioneering reusable rockets, SpaceX has established a clear lead on competitors such as Blue Origin, led by Amazon founder Jeff Bezos. The Starlink satellite business competes with, among others, AST SpaceMobile – which is relying on a SpaceX rocket to send its latest generation of satellites into orbit next week.

The prospectus filed last week says SpaceX’s biggest potential market is the sale of business-oriented artificial intelligence products designed to transform how people get work done. It’s an opportunity SpaceX predicts would be worth $22.7 trillion if it could somehow dominate rivals like Anthropic, OpenAI and Microsoft in a highly competitive industry. But the prospectus shows no clear path to profitability for the xAI business, which merged with SpaceX earlier this year.

Why Wall Street is paying attention

If the SpaceX IPO is as successful, the stock could quickly join the Nasdaq 100, a widely followed index that tracks the 100 largest non-financial companies in the composite. That's important because some popular funds, such as the $460 billion QQQ exchange-traded fund, mimic the index and will automatically buy whatever is listed in the index.

Nasdaq recently changed its rules to allow select companies to enter the Nasdaq 100 after just 15 trading days.

S&P Dow Jones Indices, on the other hand, is sticking to established and more traditional thresholds that will not allow SpaceX or other companies with gargantuan IPOs faster entry into its S&P 500 index. That means even high-profile companies will still need to wait for their stocks to trade a full 12 months before they can enter the index.

Companies want to be in the S&P 500 in particular because it's arguably the most important index on Wall Street, with trillions of dollars either mimicking it exactly or benchmarked against it. Vanguard's VOO fund that tracks the S&P 500 has roughly $950 billion invested in it, for example.
