Wing Fasteners TRIZ Cases

A bimodal door exit device integrates a latch retraction assembly with an access enable mechanism for controlled entry.

Segmented ultrasonic or LiDAR arrays eliminate blind spots near the vehicle pillar, preventing automatic door collisions with nearby obstacles.

A lock case with a segmented fastening element and mounting cap adjusts drive bolt rod length for precise positioning.

A vehicle door immobilizer bolt retracts via a trigger mechanism to bypass the body edge without rubbing contact.

A door stopper uses a deformable piston to stabilize open doors without damaging floors.

A window restrictor uses a resiliently biased stay to engage a panel peg, limiting opening within the frame gap.

Segmented pivots and a connecting rod allow non-coaxial catch placement, resolving layout restrictions in motorcycle side trunk locks.

A roller latch mechanism pivots to disengage a mobile device cover, eliminating the need for prying tools during removal.

Integrating a torsion element into the hinge member eliminates separate springs, providing impulse resistance and simplifying construction.

A self-latching sliding door system uses a retainer catch to hold panels open without manual intervention.

Electric presenting actuator pushes unlatched vehicle doors to an ajar position, breaking ice seals and preventing uncontrolled swinging.

An integrated cam member merges locking, switching, and limiting functions into one component, eliminating separate switches and reducing assembly complexity.

Biased stiles guide blunt nose bolts to prevent stile scarring while maintaining high wind stress resistance.

Inverting the engaging pin orientation prevents surface damage during closure and reduces side sill height for easier vehicle entry.

A two-way locking door stop uses a rotatable lock body to secure a door leaf in both opening and closing directions.

Dynamic reinforcement members shift with the sash to withstand high winds while preserving full emergency egress capability.

Capacitive sensors detect adult hand grip on door handle to activate latch release, preventing accidental opening during vehicle motion.

Segmenting the seal from the closure mechanism allows a small profile guard to retain child resistance without compromising seal effectiveness.

Spring-biased anti-skid cap prevents spare strut skidding, ensuring worker safety during maintenance.

Perpendicular wedge-shaped shafts on a non-tethered latch engage locking plates to delay intruders without complex installation.

Segmented mounting and locking brackets allow tool-free installation, eliminating electrical shock risk during setup.

A door assembly uses a biased locking mechanism to automatically open the door when unlocked.

A door fixing device uses a prestressing unit to maintain braking element tension against the floor.

Convex portions in aircraft openings prevent access door misassembly through physical interference.

Horizontal sliding doors with integrated sealing gaskets allow large apertures for component transport without dismantling or wind pressure interference.

A security apparatus uses wall-mounted pins and a longitudinal member to inhibit passageway closure opening.

Telescoping struts pivot the grille and raise the hood horizontally, resolving front trunk access constraints in battery electric vehicles.

An integrated anti-breach system merges the stopper into the door structure, eliminating separate ground plates and simplifying installation for daily use.

Segmented locking profiles merge into one unit to resolve the contradiction between high security and low complexity in window frames.

A sliding sash secondary lock uses a handle-operated pin biased into a frame aperture to secure the window in intermediate positions.

A tonneau cover clamp mechanism uses a cam member to convert rotational handle motion into linear clamping force.

Profile learning system coordinates dual actuators to resolve stall states from differing strokes, enabling complete door travel without extra rails.

A jamb lock door clamp secures classroom doors from the inside using a stop and pin mechanism.

A lock mechanism uses a common fastening member to operate multiple latches simultaneously.

A humanized door lock mechanism uses a single handle operation to simultaneously release the latch and deadlocking knob.

A multi-position hood prop member uses a pivoting rod and ball joint to securely hold the vehicle hood in an open position.

A movable electronic operating element shifts between stowed and extended positions on a vehicle door.

A passive door lock uses a blocking element to constrain slide movement within the housing.

Slanted hinge axes guide door free ends upward to prevent curb interference, while torsion bars replace heavy gas dampers to reduce weight.

Segmenting the holding arm into threaded and non-threaded parts allows continuous position control, eliminating friction and noise from fixed-step mechanisms.

A flexible secondary latch automatically secures the utility box lid upon closure, preventing accidental upset and spillage of contents during transport.

A resilient engaging hook and pushing element enable manual casing separation without screws.

A sash window restrictor uses a retractable tab held by magnetic latching to control the opening gap.

A window opening restrictor uses a barrier-equipped engagement recess to lock coupling bolts for flexible sash movement.

A jamb-mounted sash limiter assembly secures the opening distance using a hexalobular security screw to retain the limiting arm.

Segmented retainers prevent magnet loosening, ensuring long-term stability and easy assembly.
