Customer Introduction

This company was a startup in the consumer products industry. It identified a pressing need for a compact and user-friendly personal safety device to call for help that could easily fit in a pocket, purse, or on a keychain around the neck. With one button press, the device would call for help and operate silently just transmitting audio. It connects to smartphones via Bluetooth. It is primarily designed for use by battered women.


  • Achieve exceptional audio quality in a small, waterproof device that may be worn under clothes.

Ensure top-tier audio quality within a device not exceeding 4 cm in diameter and is waterproof.

  • Design a user-friendly button that is easy to press but avoids accidental activation.

    Electrical engineers will collaborate with the mechanical design partner to balance ease of use and prevent accidental activations.
  • Attain an extended battery life.

Battery system can last an extended period between charges to meet the stringent demands of long-term use.
