Why This Prototype Was Needed
For modern refrigerators, purchasing decisions are heavily influenced by appearance and user interaction, not just functionality.
This project required validation of:
- Large panel surface quality and color consistency
- Alignment of four-door assembly structure
- Hidden handle usability and ergonomics
- Visual integration with modern kitchen environments
👉 Direct tooling without prototyping would introduce major risks:
- Visible panel gaps or deformation
- Inconsistent surface texture across large areas
- Poor user experience with hidden handle design
- Assembly misalignment in multi-door structure
Core Engineering Uncertainties
- Appearance vs Assembly Precision
- Large panels must maintain flatness while ensuring tight assembly gaps
- Door Structure vs Long-Term Stability
- Multi-door design requires balanced load distribution
- Texture Finish vs Mass Production Consistency
- Matte/textured surfaces must remain uniform across batches
- Thermal Structure vs Sealing Performance
- Multi-zone design requires accurate sealing and isolation
Why This Process Combination Was Chosen
We used an appearance-driven prototyping strategy:
- CNC Machining → Precise large panel structure
- Vacuum Casting → Production-like surface and color
- Surface Finishing → Texture simulation (matte / fabric-like effect)
👉 This enables realistic evaluation of:
- Visual quality
- Assembly fit
- User interaction
Key Features & Advantages
1️⃣Engineering Decision Logic
We divided validation into:
- Appearance (color, texture, surface quality)
- Structure (panel alignment, gap control)
- User interaction (handle design, door opening)
👉 Ensures design decisions are validated before tooling.
2️⃣Large Panel Appearance Control
- Uniform texture finishing across wide surfaces
- Controlled color consistency (matte green tone)
- Seamless visual integration with minimal gaps
👉 Achieves premium consumer-grade appearance.
3️⃣Assembly & Structure Validation
- Multi-door alignment verification
- Gap and flushness control
- Structural reinforcement simulation
👉 Reduces risk of deformation and misalignment.
