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, turn-key solution that takes you from "idea" all the way to successful launch and sales (and every step in-between). This is our highest and most luxurious offering.  Learn more



Inventor Training and Mentorship


Learn how to build and launch your own product business with our world-class inventor training and mentorship. Product Launch Accelerator™ is the best training and mentorship program for new physical product inventors who are interested in manufacturing their own products. 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.

Design, Engineering, and Prototyping 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.

Premium Speaker DFM

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.

We'll Help You Build and Launch Your First Physical Product

"After spending years helping inventors and startups design and launch products into mass production, I finally realized why mastering the product development and launch process is the difference between success and failure."
