Upper TRIZ Cases
- Resilient Ankle Biasing Footwear for Running Speed
A resilient member connects the foot and leg to provide rotatable bias for enhanced propulsion.
- Flexible Metatarsal Guard Using Composite Layers
Composite elastomeric and fibrous layers provide puncture resistance while maintaining foot flexibility.
- Dance Training Footwear With Attachable Visual Positioning Markers
Attachable instructional objects on dance shoes provide distinct visual references for foot placement.
- Ventilated Footwear With Disconnectable Sole Portions
A ventilated article of footwear uses a disconnectable upper portion secured by exterior connectors to control airflow between the sole and the foot.
- Knitted Footwear Upper with Thermoformed Abrasion Barrier
A knitted upper integrates a thermoformed layer between knit zones to resist abrasion forces.
- Heat-Shrinkable Film Shoe Upper for Custom Fit
A shoe upper integrates a heat-shrinkable film to conform precisely to the foot shape.
- Flexible Toe Cap for Controlled Ball Spin and Tripping Prevention
A flexible toe cap changes shape to increase contact area with a kicked ball, imparting controlled spin through elastic recovery.
- Footwear Upper Mesh Material Strength and Weight Trade-off
Interlocking high tensile strength strands with non-high tensile strands in footwear mesh uppers reduces weight while maintaining durability.
- Shoe Tongue Positioning via Elastic Band and Limit Component
Elastic band connects tongue to vamp side portion, preventing drop interference during foot insertion.
- Footwear Flat Pattern Upper with Reduced Seam Construction
A footwear flat pattern upper utilizes a medial toebox seam and heel-end seam to form a dimensional article.
- Footwear Sensory Elements for Proprioceptive Feedback
Embedded rigid sensory elements transmit contact forces directly to the foot through layered upper structures.
- Puncture-Resistant Water Sport Footwear with Patterned Inserts
Patterned vulcanized rubber and nylon inserts on flexible neoprene booties shield soles and arches from stingray barbs while preserving mobility.
- Dynamic Non-Wicking PU Foam for Waterproof Shoe Materials
Dynamic non-wicking polyurethane foam integrates hydrophobic alkyl groups into the polymer chain during synthesis to create stable, waterproof materials.
