More Details
This high-frequency physiotherapy device prototype reproduces production-level aesthetics and functionality for early validation and demonstration purposes. The design addresses common challenges in medical device prototyping:
Visual System (Appearance)
- ABS Main Body: CNC-machined with high-precision surface, coated with medical-grade UV paint for durability and smooth finish.
- Metallic Buttons: Vacuum electroplated to simulate brushed metal appearance, enhancing perceived quality.
- Color Accuracy: Blue, white, and light gray segments faithfully reproduced using precision machining and seamless assembly. Pantone color matching > 98%.
Interactive System (Tactile & Operation)
- Backlit Buttons: Integrated with molded guide plates to prevent light leakage, ensure uniform illumination, and maintain clear tactile feedback.
- Protective Cover: LCD window protected by polished acrylic or tempered glass, ensuring high touch sensitivity and impact resistance.
- Mechanical Simulation: Buttons can withstand 5000 clicks without deformation, enabling realistic operation testing.
Assembly System (Precision)
- Internal Structure: PCB mounting posts and snap-fits machined with ±0.05 mm tolerance for precise assembly of electronics.
- Display Integration: Optical bonding ensures no double images and accurate touch response; preliminary dust-sealing verification performed.
- Design Validation: Engineers review snap-fit and color separation to anticipate potential issues in future dual-shot injection molding (e.g., uneven flow or delamination).
