How We Help Inventors

Product Design, Engineering, and Prototyping

Brainchild Engineering was founded by Dan Engerer in Detroit, MI as a product design and engineering agency. Starting from humble beginnings (Dan's basement), we've helped countless inventors, startups, and companies build amazing physical products. Learn more

Done-For-You Product Launch

We offer inventors a complete, turnkey solution that takes you all the way from "idea" to successful launch and sales (including every step in-between). The ultimate "sit back and relax" solution. Learn more

Product Creation and Launch Training

Learn how to build and launch your own product business with our world-class online inventor training course. Product Launch Accelerator is the best program for new physical product creators who are interested in manufacturing their own inventions. Learn more

Done-For-You Invention Licensing

Most inventors prefer the licensing approach over the manufacturing / startup approach. If that's your preference, we can handle everything and help get your product idea in front of companies for a potential licensing deal. Learn more

Frequently Asked Questions

How are we different from other "invention companies"?

Sadly, the invention industry has earned a reputation for taking advantage of inventors. Our philosophy is to educate inventors before they become our clients - and only provide solutions that provide the full picture, not just bits and pieces. Learn more about our team here.

Do I need to get a patent before I tell anyone about my idea?

Most inventors massively misunderstand how patents work, and waste huge amounts of money as a result. Click here to learn more about patents and secrecy!

How do I know you won't steal my idea?

We'll never ask you to disclose your idea to us unless you yourself want to. Legally, we're bound by a non-disclosure agreement when we work with you. But practically, our company would be done for the moment we stole anyone's idea.

When should I make a prototype?

It depends on your approach to inventing. If you want to license your idea, you most likely don't need a prototype at all. If you're going the manufacturing route, you'll eventually need a prototype, but we highly recommend getting market validation first!

Design, Engineering, and Prototype Services

A Small Sample of Our Work:

Blood Collection Mixer

For: Boekel Scientific

Tasked with full product mechanical design and engineering, Brainchild Engineers helped Boekel Scientific create an innovative medical device that’s beautiful – inside and out. The unit incorporates the functionality needed for the busiest donor stations with new-to-the-industry features to improve efficiency and operation ease.

Folding Truck Stairs

For: Jack Doheny Companies

The JDC folding staircase offers improved job site safety to truck-based pipeline inspection crews. Starting with only a handful of measurements, Brainchild engineers designed, refined, and prototyped the industrial staircase to perfection. 3D CAD, FEA simulation, DFMA, and extensive in-house prototyping were all employed to launch the customer into successful production.

Dialtune Snare Drum

For: Dialtune

Dialtune is a truly game-changing approach to drum tuning and head replacement, transforming a 5+ minute hassle into about 30 seconds. In addition to saving time, the Dialtune system achieves pitch-perfect tone consistency every time due to the balanced and symmetrical product layout. Brainchild was able to take the project to successful production launch where multiple other PD firms couldn't.

GoBout Multi-dispenser

For: GoBout

GoBout is a personal hygiene product which stores many different liquids (shampoo, body wash, lotion, conditioner, etc.) in one simple container rather than many. GoBout hired Brainchild Engineering to design their product from scratch, working closely together to develop and refinea product that is as simple as can be.

E-Z Leaf Yard Tool

For: E-Z Leaf

Raking leaves can be a pain. But with the E-Z Leaf, at least that pain won’t be in your back! Inventor Charles Richison approached Brainchild with a novel idea and a hand-made prototype. What he got in return was a production-ready design that’s optimized for low-cost manufacturing.We take the most direct route possible to bring our customers to efficient mass production.

Design for Manufacturing Optimization

For: Detroit Audio Lab

Detroit Audio Lab offers a truly unique product: Premium speakers made with reclaimed wood from Detroit homes. Brainchild Engineering helped DAL scale their operation with efficient design-for-manufacturing, working together through concept and in-house rapid physical prototyping on a 3-axis CNC wood mill.

CFT Vermicomposter

For: Michigan Soilworks

Michigan Soilworks is breaking new ground in the vermicomposting industry with their new CFT (continuous flow-through) blade module. Creating the most efficient motorized rig in the industry requires precision engineering. Working closely with MSW, we developed, prototyped, and optimized their cutting edge automatic drivetrain, offering cost-effective solutions for soil life operations.

Softball Pitch Trainer

For: Spin Dr.

Invented by 4-time All-American USA Softball National team member Jamie Southern, the Spin Dr. training ball helps pitchers visualize and correct their pitches. We precisely engineered this product to mimic the feel and spin of a real ball while maintaining a geometric center of gravity (despite having a non-uniform shape). Learn more at myspindr.com

SparkPod Handheld Showerhead

For: SparkPod

Leading premium showerhead manufacturer SparkPod approached Brainchild Engineering to create a super high-quality handheld showering experience without the super high price tag. We were able to cut down development time and cost using computational fluid dynamic simulations. We were able to design an extremely low-cost product thanks to manufacturing process optimization.
