Doors/Windows TRIZ Cases
- Semi-fixed Wing Double Door Lock with Pivoting Lever
A pivoting lever actuating mechanism controls drive rods for a semi-fixed wing double door lock, eliminating pre-milling requirements during installation.
- Hands-Free Vehicle Door Actuation via Gesture and RF Detection
An automated door system replaces manual handle operation with optical gesture and RF detection, enabling hands-free entry for occupants carrying items.
- Thermoplastic Spacer Profile for Glazing Security and Insulation
Segmented glass-polymer panes with a U-shaped spacer reduce thermal conductivity while maintaining high burglary protection.
- Flap-Based Access Control Gate for Ski Lifts
A contactless access control gate uses motor-driven flaps and RFID readers to verify patron entry rights at ski lift entrances.
- TeO2-V2O5 Glass for Low-Temperature Vacuum Insulation
A TeO2-V2O5 glass mixture enables vacuum compaction at temperatures below 450 °C.
- Self-Sealing Membrane Valve for Insulating Glass Pressure
A self-sealing membrane valve assembly integrates into insulating glass units to enable internal pressure adjustment through elastic deformation.
- Hydraulic Cylinder Control for Swing Garage Doors
A hydraulic cylinder control system maintains alignment during operation.
- External Aluminum Profile Window Frame Reinforcement
Relocating steel reinforcement to an external aluminum profile eliminates thermal bridges while maintaining torsional rigidity for large window frames.
- Adjustable Guide Device for Sliding Elements
Rotatable guide part with structured contact surfaces enables quick lateral adjustment of sliding elements.
- Profile Assembly Clamping Flange Anchoring Spacer
Bendable clamping flanges secure an insulating spacer within segmented chambers, resolving mechanical strength and thermal insulation trade-offs.
- Plug-connector for Insulating Glass Spacer Profiles
Elastically deformable lamellae grip thin-walled spacer hollow profiles, accommodating surface tolerances while maintaining structural integrity.
- Extendable Protective Wall for Rail Platforms
A dual-wall structure resists pressure waves from passing trains, enabling safe platform protection without precise train stopping.
- Rigid Polyurethane Foam Composite Profiles Deformation
Optimized rigid polyurethane foam composition prevents profile deformation during painting while eliminating dust generation from cutting operations.
- Aluminum Corner Connector with Grooved Adhesive Channel
Grooves in the central web direct adhesive to miter surfaces while preventing leakage into hollow chambers, reducing manufacturing costs.
- Inclined Building Window Waterproofing via Projecting Pane
Projecting pane elements direct precipitation away from structural gaps, resolving waterproofing reliability issues at low inclinations.
- Transreflective LCD with Embossing Polarizer for Dual-Side Display
A transreflective liquid crystal display uses a moth-eye embossing polarizer to enable bidirectional image viewing.
- Thermally Separated Aluminum Window Profiles with Plastic Barriers
Plastic chamber profiles eliminate thermal bridges in aluminum window systems, preventing condensation while maintaining structural strength.
