Wing Fasteners TRIZ Cases
- Bimodal Door Exit Device with Delayed Egress and Immediate Access
A bimodal door exit device integrates a latch retraction assembly with an access enable mechanism for controlled entry.
- Vehicle Swing Door Obstacle Detection Using Distributed Sensors
Segmented ultrasonic or LiDAR arrays eliminate blind spots near the vehicle pillar, preventing automatic door collisions with nearby obstacles.
- Espagnolette Lock Bolt Rod Length Adjustment Mechanism
A lock case with a segmented fastening element and mounting cap adjusts drive bolt rod length for precise positioning.
- Vehicle Door Immobilizer Bolt Trigger Mechanism
A vehicle door immobilizer bolt retracts via a trigger mechanism to bypass the body edge without rubbing contact.
- Door Stopper With Deformable Piston For Floor Protection
A door stopper uses a deformable piston to stabilize open doors without damaging floors.
- Concealed Window Restrictor for Tilt and Turn Mechanisms
A window restrictor uses a resiliently biased stay to engage a panel peg, limiting opening within the frame gap.
- Pivoting Door Guard Prevents Fixed Side Closing
A pivoting door guard swivels to block the fixed side opening, preventing finger trapping while allowing full door closure when retracted.
- Aircraft Luggage Lock with Cable-Driven Dual Hooks
Cable-driven gear rack pivots dual locking hooks to secure aircraft luggage, eliminating shafts that increase weight and assembly complexity.
- Motorcycle Side Trunk Lock Non-Coaxial Catch Mechanism Layout
Segmented pivots and a connecting rod allow non-coaxial catch placement, resolving layout restrictions in motorcycle side trunk locks.
- Roller Latch Mechanism for Easy Mobile Cover Removal
A roller latch mechanism pivots to disengage a mobile device cover, eliminating the need for prying tools during removal.
- Case Latch Assembly Torsion Hinge Biasing
Integrating a torsion element into the hinge member eliminates separate springs, providing impulse resistance and simplifying construction.
- Self-latching Sliding Door System for Wind Resistance
A self-latching sliding door system uses a retainer catch to hold panels open without manual intervention.
- Vehicle Door Presenting Actuator for Icy Conditions
Electric presenting actuator pushes unlatched vehicle doors to an ajar position, breaking ice seals and preventing uncontrolled swinging.
- Rotating Shaft Automatic Locking via Wedge Cam Mechanism
An integrated cam member merges locking, switching, and limiting functions into one component, eliminating separate switches and reducing assembly complexity.
- Window Frame Blunt Nose Bolt Stile Design
Biased stiles guide blunt nose bolts to prevent stile scarring while maintaining high wind stress resistance.
- Vehicle Side Structure Engaging Pin Inversion
Inverting the engaging pin orientation prevents surface damage during closure and reduces side sill height for easier vehicle entry.
- Two-Way Locking Door Stop with Rotatable Lock Body
A two-way locking door stop uses a rotatable lock body to secure a door leaf in both opening and closing directions.
- Movable Channel Reinforcements for Hurricane-Resistant Window Assemblies
Dynamic reinforcement members shift with the sash to withstand high winds while preserving full emergency egress capability.
- Proximity Sensor Door Latch Release Mechanism
Capacitive sensors detect adult hand grip on door handle to activate latch release, preventing accidental opening during vehicle motion.
- Child Resistant Closure Guard with Independent Seal Mechanism
Segmenting the seal from the closure mechanism allows a small profile guard to retain child resistance without compromising seal effectiveness.
- Engine Hood Strut Anti-Skid Cap Design
Spring-biased anti-skid cap prevents spare strut skidding, ensuring worker safety during maintenance.
- Non-tethered Latch With Wedge Shafts for Classroom Security
Perpendicular wedge-shaped shafts on a non-tethered latch engage locking plates to delay intruders without complex installation.
