PDT an Astronics Company: Product Design and Development Firm in Chicago, IL

Building off of the success of the 360 Massage Line and utilizing extensive customer and retailer feedback, we joined forced again to create a series of lightweight and intuitive tools featuring feely rotating massage spheres that offer premium sports massage for the entire body.

Doing More With Less

We started to develop concepts that enabled the most versatile use scenarios and developed improved rotating massage spheres, facilitating 360 degree massage with deeper and more targeted muscle manipulation. The end result was cutting the number of spheres on each product almost in half – while increasing the diameter of each sphere in order to dig deeper into the user’s body with less effort.

Feedback from the Pros

We took our research prototypes to specialty running stores, attended group runs, and met runners at the finish lines to get feedback on what worked best.

Integrate Our Learnings

Based on user feedback, our team raised the center sphere of the foot massager so it hits the arch of the foot and allows for a more intense, deep tissue massage while the five surrounding 1-inch spheres work the sides of the feet all the way up to the toes. We also refined the handles, grips and other details of the stick to most effectively deliver on the desires of the target market.

Everything Is Rolling Smoothly

Our mechanical engineering team was challenged in capturing the thin, light industrial design while keeping a rigid and robust stick. Additionally, the new sphere material presented its own challenge in requiring the right tolerances in the plastic housing and spheres for the best rolling experience.
