Design and develop an innovative, ergonomic, and cost effective ultrasonic lighted insert for dental use


Hu-Friedy approached Slingshot with an idea for a lighted insert and a competitive patent that we had to design around to improve practitioner and patient experience.


  • Functional pre-market prototypes that met all client performance and cost requirements

  • Client was able to successfully file patent application

  • Improve grip ergonomics


Designed around a competitive patent by utilizing an LED illuminated phosphor and lens to create a white light source reaching a brightness of 3000 lux.

Electronics had to be miniaturized and robust enough to withstand a harsh aqueous environment.

Optimized power transfer from the hand piece to the light source without compromising the ultrasonic performance of the product, or the ability of the insert to rotate freely in the hands of the user.
