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:

2 Houston space tech cos. celebrate major tech milestones

big wins

Two Houston aerospace companies — Intuitive Machines and Venus Aerospace — have reached testing milestones for equipment they’re developing.

Intuitive Machines recently completed the first round of “human in the loop” testing for its Moon RACER (Reusable Autonomous Crewed Exploration Rover) lunar terrain vehicle. The company conducted the test at NASA’s Johnson Space Center.

RACER is one of three lunar terrain vehicles being considered by NASA for the space agency’s Artemis initiative, which will send astronauts to the moon.

NASA says human-in-the-loop testing can reveal design flaws and technical problems, and can lead to cost-efficient improvements. In addition, it can elevate the design process from 2D to 3D modeling.

Intuitive Machines says the testing “proved invaluable.” NASA astronauts served as test subjects who provided feedback about the Moon RACER’s functionality.

The Moon RACER, featuring a rechargeable electric battery and a robotic arm, will be able to accommodate two astronauts and more than 880 pounds of cargo. It’s being designed to pull a trailer loaded with more than 1,760 pounds of cargo.

Another Houston company, Venus Aerospace, recently achieved ignition of its VDR2 rocket engine. The engine, being developed in tandem with Ohio-based Velontra — which aims to produce hypersonic planes — combines the functions of a rotating detonation rocket engine with those of a ramjet.

A rotating detonation rocket engine, which isn’t equipped with moving parts, rapidly burns fuel via a supersonic detonation wave, according to the Air Force Research Laboratory. In turn, the engine delivers high performance in a small volume, the lab says. This savings in volume can offer range, speed, and affordability benefits compared with ramjets, rockets, and gas turbines.

A ramjet is a type of “air breathing” jet engine that does not include a rotary engine, according to the SKYbrary electronic database. Instead, it uses the forward motion of the engine to compress incoming air.

A ramjet can’t function at zero airspeed, so it can’t power an aircraft during all phases of flight, according to SKYbrary. Therefore, it must be paired with another kind of propulsion, such as a rotating detonation rocket engine, to enable acceleration at a speed where the ramjet can produce thrust.

“With this successful test and ignition, Venus Aerospace has demonstrated the exceptional ability to start a [ramjet] at takeoff speed, which is revolutionary,” the company says.

Venus Aerospace plans further testing of its engine in 2025.

METRO rolls out electric shuttles for downtown Houston commuters

on a roll

The innovative METRO microtransit program will be expanding to the downtown area, the Metropolitan Transit Authority of Harris County announced on Monday.

“Microtransit is a proven solution to get more people where they need to go safely and efficiently,” Houston Mayor John Whitmire said in a statement. “Connected communities are safer communities, and bringing microtransit to Houston builds on my promise for smart, fiscally-sound infrastructure growth.”

The program started in June 2023 when the city’s nonprofit Evolve Houston partnered with the for-profit Ryde company to offer free shuttle service to residents of Second and Third Ward. The shuttles are all-electric and take riders to bus stops, medical buildings, and grocery stores. Essentially, it works as a traditional ride-share service but focuses on multiple passengers in areas where bus access may involve hazards or other obstacles. Riders access the system through the Ride Circuit app.

So far, the microtransit system has made a positive impact in the wards according to METRO. This has led to the current expansion into the downtown area. The system is not designed to replace the standard bus service, but to help riders navigate to it through areas where bus service is more difficult.

“Integrating microtransit into METRO’s public transit system demonstrates a commitment to finding innovative solutions that meet our customers where they are,” said METRO Board Chair Elizabeth Gonzalez Brock. “This on-demand service provides a flexible, easier way to reach METRO buses and rail lines and will grow ridership by solving the first- and last-mile challenges that have hindered people’s ability to choose METRO.”

The City of Houston approved a renewal of the microtransit program in July, authorizing Evolve Houston to spend $1.3 million on it. Some, like council member Letitia Plummer, have questioned whether microtransit is really the future for METRO as the service cuts lines such as the University Corridor.

However, the microtransit system serves clear and longstanding needs in Houston. Getting to and from bus stops in the city with its long blocks, spread-out communities, and fickle pedestrian ways can be difficult, especially for poor or disabled riders. While the bus and rail work fine for longer distances, shorter ones can be underserved.

Even in places like downtown where stops are plentiful, movement between them can still involve walks of a mile or more, and may not serve for short trips.

“Our microtransit service is a game-changer for connecting people, and we are thrilled to launch it in downtown Houston,” said Evolve executive director Casey Brown. “The all-electric, on-demand service complements METRO’s existing fixed-route systems while offering a new solution for short trips. This launch marks an important milestone for our service, and we look forward to introducing additional zones in the new year — improving access to public transit and local destinations.”
