More Details
This shift panel assembly represents a typical interior HMI component where appearance, tactile response, and component integration are validated together.
The main structure was injection-molded using automotive ABS, selected for durability, dimensional stability, and moldability suitable for interior applications.
Surface treatments ranged from piano-black high gloss to matte or textured finishes to reduce fingerprints and enhance daily usability.
Decorative trims were realized through vacuum electroplating on plastic, providing a metallic appearance while controlling weight and structural complexity.
Functional button areas were produced using in-mold injection combined with durable printing to maintain clear, wear-resistant symbols under repeated operation.
Crystal-style gear selector components were precision cut and polished in acrylic or resin to enhance light reflection and perceived quality.
This approach allowed appearance, interaction, and assembly feasibility to be validated in a single integrated prototype, reducing fragmented verification steps.
Key Features & Advantages
1️⃣Engineering-Driven Decision Making
Material and process selections were determined by interior use conditions, tactile requirements, and integration risks, minimizing trial-and-error during validation.
2️⃣High-Fidelity Appearance and Interaction
Surface finishing, electroplated trims, and precision-cut transparent components ensured the prototype closely matched intended production appearance and user perception.
3️⃣Integrated Functional Validation
Structural parts, decorative elements, buttons, and PCB were assembled into a compact module, enabling full functional testing rather than isolated part evaluation.
4️⃣Fast Validation Loop
By combining appearance, interaction, and assembly checks into one prototype cycle, the development timeline is streamlined for efficient system-level validation.
