Upper TRIZ Cases
- Flexible Footwear With Segmented Waterproof Bands
Segmented waterproof bands and pivot slots resolve the strength versus flexibility trade-off in stiff boots.
- Shoe With Heel-Access Top Member for Easy Foot Insertion
A shoe top member opens at the heel and folds back to allow foot insertion.
- Safety Toe Cap Fibrous Coating Thermal Insulation
A fibrous coating on a safety toe cap generates an air gap that prevents cold downdraft and retains warmth without adding bulk.
- Footwear Felting Transition Between Materials
A footwear upper joins panels using a backing panel with fibers mechanically embedded in adjacent layers to create a gradient transition.
- Footwear Containment Piece for Arch Support
A knitted footwear component uses a medial containment piece to reduce pronation risk.
- Auxetic Footwear Upper with Variable Opening Perimeters
An auxetic footwear upper structure expands surface area under tension to accommodate varying foot shapes and sizes.
- Footwear Upper Incised Layer Design for Flexibility
Segmenting the upper into distinct layers resolves the contradiction between wear-resistance and flexibility by allowing localized material removal.
- Multi-Layer Vamp Construction for Waterproof Breathable Footwear
Segmented layers resolve the contradiction between water resistance and breathability while maintaining flexibility.
