Never Ending Defender®

The Never Ending Defender is a basketball training device developed to teach you to shoot with a defender in your face and practice dribbling without seeing the ball.

Product design of the Panwaffle - a skillet that create a hybrid waffle and pancake.


You no longer have to choose between pancakes and waffles. Have both. This innovative design features stay-cool handles, comes apart easily for the dishwasher, and works on a variety of cooking surfaces.

The Humboldt-Ecoclone ultrasonic fog plant propagation system.

Humboldt Ecoclone™ Ultrasonic Fog Cloning System

This revolutionary aeroponic plant propagation system uses ultrasonic fog technology to create a market-disruptive plant cloning device. Disruptive because the design solved all the problems associated with traditional plant cloners, while only using a third of the energy, and half of the water.

Industrial design of a handheld radiation detector for homeland security and defense sectors.

Radiation Detector

Serving the Homeland Security and Defense sectors, this new device utilizes crystal technology to scan and detect trace levels of radiation and protect against terrorist threats.

Product design for a pilates workout table.

Revision Pilates Table

Designed for the home, this compact workout platform offers a full range of Pilates exercises and folds away for easy storage.

Product development of a children's nutritional tracking system.

Clean fitness centers easily with the GymValet bottle and towel holder.

GymValet® Bottle and Towel Holder

A holder for sanitizing spray bottles and towels, the GymValet attaches directly to all strength training and cardio equipment without any tools.



The first stage for creating a new product, after researching competitive designs that already exist, is to create a series of concept sketches that explore possible features, colors and methods for manufacture. They’re also useful for obtaining feedback from focus groups or generating interest from potential investors.

Computer Modeling & Prototypes

Using 3D modeling programs, we can build digital representations of a product idea and use that data to generate functional prototypes, renderings, and parts ready for manufacture. It’s a time-saving way to test ideas and assumptions before committing to a final design.

Ergonomic Analysis

Ergonomics discovers and applies information about human behavior, abilities, and limitations. The first step in designing a good product is to consider the user. Process, Materials, and Measurements – a reference book for industrial designers – is a collaboration by the faculty at the Cleveland Institute of Art. Carla Blackman, principal at Design Interface, authored the chapter on Ergonomics. She has taught the subject for over 30 years at CIA
