Wing Fasteners TRIZ Cases

A planar base supports a flexible cantilever arm that frictionally holds doors while eliminating floor protrusion and tripping hazards.

A hood prop assembly uses a rotating retainer mechanism to lock and unlock securely against the vehicle hood panel slot.

A window opening control device uses pivotable restrictor arms to limit sash travel and prevent accidental openings.

Radar sensors detect pedestrians to trigger a solenoid that releases a torsion spring, raising the hood to absorb impact energy.

Axial displacement of a single support sleeve eliminates overlapping sleeves, reducing radial dimensions and weight while enhancing buckling resistance.

Interior-mounted hinge brackets pivot a door bar between collapsed and locked states, preventing break-ins without damaging wall structure.

A door security device uses a blocking element to prevent unauthorized hinge pin extraction.

Segmented leaf design with a riveted limiting block simplifies fabrication while ensuring reliable rotational angle limitation.

Spatially varying magnetic attraction biases the pet door flap closed against wind pressure while enabling easy corner release for pets.

A window restrictor uses pivotable members and a key-operated locking mechanism to secure the device.

An adjustable loop cinches around a handle while a catch member anchors to a frame, maintaining tension against wind forces.

Axial clearance between the cam follower and cam member prevents friction during rotation, ensuring smooth operation.

Segmented locking elements and guides maintain window sash stability under high wind loads, preventing slamming while allowing controlled ventilation.

Segmented housing and guide roller bearings reduce friction while resolving space constraints.

A magnetic lifting mechanism adjusts a chassis cover to create spacing for airflow while maintaining silent operation.

A door barricade apparatus slides under the door and tightens against the jamb to restrict access.

Segmented door stiles with internal channels guide drive rods to resolve alignment difficulties during machining.

A plunger ratchet lock uses a cam driver to engage a serrated locking bar.

A vehicle exit assist system uses counterforce devices to block door opening when space is insufficient.

A tilt latch retainer apparatus houses modular assemblies within a sash channel to simplify component insertion and replacement.

A tensioned cable with a bulge and angle fitting anchors window casements to the frame.

An adjustable metal compartment clamps onto a notched strike plate to resist forced entry.

A tilting cover plate protects ferromagnetic components from corrosion while enabling adjustable magnetic force for secure door stopping.

Integrated L-shaped fixtures hold flat magnets to attach the cover, eliminating precise placement errors and solidification delays.
