Hapta / L'Oreal / 2022

A handheld, ultra-precise smart makeup applicator for individuals with limited hand and arm mobility.

Skills

Hapta is a handheld device that maintains a stabilized end point when the handle is subjected to shaky movement. The device uses accelerometers and other sensors to measure device motion and then provide mitigating motion through a 360-degree articulating joint. Hapta is a product from Lancome/L'Oreal.

As the lead engineer on the program, I led mechanical concept generation, CAD development, rapid prototyping, and vendor management activities. This development effort was focused on the adjustable housings and mechanical architecture of the end effector and did not include the internal electromechanical subsystem.

Process
CAD Exploration
CAD Exploration

I was tasked with rapidly exploring the existing architecture and developing mechanical concepts for the device's primary articulating ball joint. The shown CAD is development CAD and not the final embodiment.

Rapid Prototyping

I leveraged 3D printing to rapidly explore several mechanism concepts.

Casting + Molding

I also led a casting and injection molding prototyping effort for the device's compliant sleeve that protects the main joint.

CMF Prototyping

I produced design files and managed vendors during a rapid prototyping process to achieve consistent, brand-specific colors, materials, and finishes (CMF).

Final Build
Final Build

I generated all prototyping files and managed several vendors to build 10 works-like prototypes for internal user validation studies.
