Electric Toothbrush Product Development
TL;DR: OPD Design delivered the electric toothbrush product development — an IPX7 waterproof, low-noise electric toothbrush designed for the Southeast Asian market. The project covered industrial design with cultural aesthetics, mechanical optimization, hardware and firmware development, prototyping, and mold development.
Project Background
The electric toothbrush market in Southeast Asia demands products that combine cultural relevance, reliable performance, and affordable pricing. Existing products often fail to address local aesthetic preferences or compromise on waterproofing and noise control. OPD Design led the full electric toothbrush product development process, from market research and concept design through to mass production, delivering a product that meets Southeast Asian consumer expectations while maintaining manufacturing cost efficiency.

Product Development Process
Step 1-Product Strategy
We conducted in-depth market research on Southeast Asian consumer preferences, analyzing cultural aesthetics, price sensitivity, and feature priorities. This research informed the product requirements document, defining design direction, target price point, and key differentiators for the regional market.
Step 2-Industrial Design
The industrial design team created multiple concepts integrating Southeast Asian cultural elements with modern product aesthetics. After client review and user testing, the final design featured a streamlined form with refreshing colors that appeal to local consumers while maintaining manufacturing feasibility.
Step 3-Mechanical Design
Mechanical engineers optimized the internal structure to achieve high vibration frequency with minimal noise. The motor mounting system, gear train, and housing were designed for durability and user comfort. Detailed mold development requirements were documented to ensure production quality and cost control.
Step 4-Hardware and Firmware Development
Hardware development included electronic component selection, circuit board design, and driver development. The firmware team created the control program for brush operation modes, battery management, and safety protection. Integration testing ensured hardware and firmware stability and reliability.
Step 5-Functional Prototyping
Step 6-Mold Development
Step 7-Manufacturing
