Core question: What material aligns with your expectations?
ABS (Acrylonitrile Butadiene Styrene)
- Lightweight, impact-resistant, lower cost than PC material
- Economical cases, internal frames
PC (Polycarbonate)
- High compressive strength, lightweight, scratch-resistant
- Premium business cases, frequent check-in luggage
Aluminum-Magnesium Alloy
- Metallic texture, deformation-resistant, high load-bearing capacity
- Luxury metal cases, anti-theft applications
Oxford Fabric/Canvas
- Durable, heavy, prone to aging
- Vintage-style luggage, low-cost customization
Functional Requirements
Smart features:
- Integrated Tech: Smart locks (e.g., TSA-approved), USB charging ports, GPS tracking, or weight sensors.
- Enhanced security: Dual-layer zippers, reinforced lock systems.
- Ergonomics: Adjustable telescopic handles, ergonomic grip designs.
Component Selection
Wheels:
- Types: Spinner wheels (360° rotation), Inline wheels (sturdy for rough terrain) .
- Material: TPU/TPE (quiet, shock-absorbent) or Steel bearings (heavy-duty).
Telescopic handle:
- Material: Aluminum alloy (lightweight, corrosion-resistant) or Full aluminum (high-end durability).
- Other hardware: Zippers (YKK recommended), locks, and corner guards.
Lining Material
Options:
- Polyester (affordable, easy to clean), Cotton blends (soft, breathable), Peach-skin velvet (luxury texture), or Antimicrobial fabrics (hygienic).
- Design tips: Include organizational pockets, compression straps, and waterproof compartments.
Technical Documentation
Required deliverables:
- Structural diagrams: Specify dimensions, weight distribution, and load-bearing points.
- 3D renderings: Visualize aesthetics, color schemes, and functional layouts (e.g., smart lock placement).
- Prototyping: Validate design feasibility through CAD models and physical samples.
