Upper TRIZ Cases
- Athletic Footwear Ball Control Portions
Segmented footwear upper portions with distinct gripping members and protrusions improve shooting accuracy and spin management.
- Self-Opening Shoe With Medial Lateral Spring
A shoe-opening spring exerts medially and laterally outward forces to expand the upper.
- Luminous Footwear Connection Unit Asymmetry
An asymmetric connection port layout prevents cable damage and reduces tongue thickness in luminous footwear.
- Sports Shoe Selectively Pivotable Tongue Skiing Walking Transition
Segmented tongue structure resolves external ski-walk device hindrance by integrating internal locking to adjust rigidity for varied support conditions.
- Footwear Leather Anti-Stretch Welding
Ultrasonic welds in footwear leather maintain shape retention by resisting deformation during wear.
- Footwear Concealing Layer Using Structural Color for Waste Reduction
A concealing layer obscures substrate properties using structural color to repurpose excess manufacturing materials.
- External Heel Counter with Arcuate Rubber Geometry
An external molded rubber heel counter features arcuate lateral sides to secure footwear support without extending along the heel.
- Animated Shoelace Loop Holder for Teaching Tying
A flexible footwear accessory device with pre-formed holes and slit-apertures forms an animated character to hold shoelace loops in place.
- Shoe Charm Holder with Magnetic Attachment
Segmented charm holders use magnetic attraction to attach decorations, resolving the trade-off between easy removal and reliable holding strength.
- Footwear Side Panels with Custom Hand Gesture Elements
Segmented side panels accept removable hand gesture graphics, resolving the trade-off between manufacturing simplicity and personalized aesthetic appeal.
- Integral Shoe Ankle Support Molding and Stability
An integrated shoe ankle support merges with the counter structure to eliminate shifting friction during wear.
- Internal Metatarsal Guard for Flexible Footwear
An internal metatarsal guard integrates under the outer layer to protect the foot while maintaining flexibility.
- Interchangeable Shoe Ornamenting Device with Modular Pin Attachments
Modular pin attachments secure interchangeable bands to shoe loops, resolving the contradiction between simple structure and customizable appearance.
- Ballet Pointe Shoe High-Waisted Sole Design
Repositioning the sole waist to 65 percent of length from toe improves arch support and extends shoe life.
- Footwear Air Permeable Layer for Breathability and Waterproofness
A footwear upper arrangement uses a three-dimensional air permeable layer to enable horizontal gas exchange between the interior and exterior.
- Skate Boot Liner Abrasion Resistant Overlay Design
Skate boot inner liner uses abrasion resistant overlays in high friction zones to extend material durability without reducing comfort.
- Footwear Upper Wound Thread Pattern for Stability and Propulsion
Wound thread patterns enhance stability and propulsion while resolving durability versus manufacturing complexity trade-offs.
- Ornamental Fastener for Clothing with Integrated Aesthetic Design
An ornamental fastening system merges decorative and functional roles to secure removable elements on wearable substrates.
