The Idea and Problem
This project is a complete consumer product design case study user research, industrial design, DFM, and manufacturing support for a screen-free visual timer that helps children manage morning and bedtime routines independently.
The problem. Parents rely on constant reminders or screen-based apps to keep kids on schedule. Interviews with families revealed the need for a tactile, kid-operated tool: something visual enough for a 4-year-old, durable enough for daily abuse, and simple enough to work without a parent.
Product design and development. I designed a kid-friendly visual timer with swappable task icons, LED progress indicators, and preset buttons for 5, 10, and 15 minutes. The single-button interface was validated through multiple prototype rounds tested with real children each round simplified the interaction and improved clarity. Key engineering decisions included BPA-free ABS material selection, snap-fit assembly to reduce fasteners and cost, wall-thickness and draft optimization for injection molding, and drop-test-driven internal ribbing.
Launch and Impact
Design for manufacturing. I prepared complete production files — CAD, 2D drawings with tolerances, CMF specification — and worked directly with a Shenzhen-based injection molding partner through tooling, T1 samples, and production sign-off.
Result. Launched on Amazon in 2023, the timer became a top seller in the Kids Clocks category and is now used in hundreds of households as a screen-free habit-building tool.

The timer is now available on the market and being used by families around the world to build healthier routines for kids. You can check out the product, read reviews, or purchase it directly from Amazon using the link below:
