The goal was to design a haptic touch trigger for a next-generation spray bottle. Because the electronic architecture eliminated the need for a mechanical trigger, the core challenge was recreating a natural, intuitive actuation experience. We utilized a precise combination of surface texturing and responsive vibrations to provide the user with tactile confirmation.

I spearheaded the interaction of the trigger mechanism. By collaborating with engineering and leadership teams, I fine-tuned the ergonomics and ensured the touch activation felt responsive. I designed and prototyped over 50 variations of the trigger, rigorously exploring different shapes, textures, and ergonomic profiles.

I deployed a hybrid rapid prototyping strategy to maintain an aggressive R&D timeline. FDM printing was utilized for high-speed volume studies, allowing the team to make rapid decisions regarding scale and hand-feel. Once the macro-ergonomics were locked, I transitioned to high-fidelity SLA printing to validate precise surface textures, mechanical tolerances, and the final design direction.
