Massage Comb Development

TL;DR: OPD Design delivered end-to-end massage comb development for a smart electric scalp massage comb with wireless charging base. The project covered industrial design, mechanical engineering, hardware and firmware development, prototyping, mold development, and mass production with FCC/CE certification.

Project Background

The personal hair care appliance market has seen strong growth, with industry estimates suggesting annual expansion in the mid-20% range and rising consumer interest in portable all-in-one tools. Users face fragmented hair care routines — separate products for brushing, oil application, and scalp treatment — and existing tools typically serve single functions. OPD Design partnered with a client to develop a portable smart massage comb that integrates brushing, essential oil misting, and wellness features into one device, addressing the gap in the market for a cohesive at-home and travel-friendly hair care solution.

Solution

OPD Design developed a smart electric massage comb that combines brushing, essential oil misting, and scalp wellness functions in one portable device. The comb body integrates a micro essential oil tank and an atomization spray system, delivering uniform mist during combing — paired with soft rubber round-tip teeth that are gentle on the scalp and reduce hair pulling. A high-concentration negative ion module neutralizes static electricity in real time to eliminate frizz, while a low-power red light care zone emits mild red light during use to support local scalp circulation. The device features a lightweight ABS body (designed to weigh approximately 150g) and a contact-based wireless charging base — no cables to plug or unplug, reducing wear on wired interfaces and eliminating liquid leakage risks. The base doubles as storage, keeping the comb dustproof and moisture-proof. One-key control and a detachable, washable essential oil tank make it suitable for home, commuting, and travel use.

Our Massage Comb Development Process

Step 1-Product Definition & Market Research

We analyzed the personal hair care appliance market and identified the opportunity for a portable all-in-one tool that integrates brushing, essential oil misting, and scalp wellness. User research covered core scenarios — home use, commuting, and travel — and clarified requirements around atomization uniformity, wireless charging convenience, and lightweight portability. Technical evaluation confirmed the feasibility of integrating contact-based wireless charging, negative ion generation, and red light therapy into a single compact form factor.

Step 2-Industrial Design

The design team developed multiple concept sketches focusing on grip curvature, one-key control placement, and the form of the wireless charging base. The final design balanced ergonomic comfort during extended use with a compact footprint that fits easily in a travel bag. The charging base was designed to double as a storage dock, keeping the comb dustproof and moisture-proof when not in use.

Step 3-Mechanical (Structural) Engineering

We produced detailed 3D models clarifying component dimensions, assembly relationships, and the sealing architecture for the essential oil tank. Critical engineering challenges included preventing leakage at the atomization interface, ensuring the wireless charging coil alignment remained stable during use, and optimizing the structural stability of the charging base. Material selection finalized ABS for the body and soft rubber for the round-tip comb teeth.

Step 4-Hardware & Firmware Development

The hardware team designed the circuit architecture integrating the wireless charging receiver, negative ion generator, red light LED array, atomization driver, and one-key control logic. Firmware was developed to manage power distribution, misting duration, and safety shutoffs. All electronic modules were coordinated to fit within the compact body while meeting thermal and electromagnetic compatibility requirements.

Step 5-Functional Prototyping

We produced 10–20 handboard prototypes with all core functions and ran multi-dimensional testing: atomization particle size and uniformity, negative ion output, red light wavelength accuracy, wireless charging efficiency, and battery life. User experience testing covered grip comfort, one-key operation intuitiveness, and travel scenario usability. Reliability testing included environmental exposure, drop tests, and leak prevention validation.

Step 6-Mold Development

After design validation, we developed precision molds for the comb body, charging base, and internal components. We coordinated with mold suppliers to ensure dimensional accuracy, surface finish quality, and production efficiency. The mold development phase included T0/T1 sampling and adjustment cycles to refine draft angles, parting lines, and gate positions while preserving the clean exterior surfaces.

Step 7-Supply Chain & Mass Production Support

We managed the transition from pilot run to mass production, coordinating component sourcing, assembly line setup, and quality control inspections. The product completed 3C certification for the China market and FCC/CE certification for export to the United States and European Union. Production capacity was scaled to meet target volumes while maintaining consistent quality standards across all units.
