Safety Belts TRIZ Cases

Multiple pawls prevent dust-induced sticking and gravitational misalignment by engaging independently at extreme positions.

Lateral tensile members extend from the socket to increase pull-out resistance and prevent concrete cracking under load.

A fall arrest apparatus uses a pivotable weight pan to engage a surface for frictional anchoring.

Hook elements on the rail edge engage the traveller to prevent falls without manual line adjustment or complex moving parts.

Segmented apertures on a safety interface plate prevent entanglement among lanyards and rescue hooks while enabling retrofitting to existing harnesses.

Integrating fall protection onto the working crane eliminates separate equipment, while dynamic anchorage prevents pendulum swings during operator movement.

Eliminating stitch failure in multilayer-sewn structures, this design uses seamless annular webbing to prevent breakage under high-strength conditions.

A binding strap encloses a safety harness belt to form an integrated attachment eyelet, reducing production complexity while maintaining anchoring strength.

Telescopic bars adjust the upright structure to anchor PPE securely without wall drilling or structural damage.

Segmented pawl systems manage distinct force thresholds to resolve the trade-off between safety reliability and reset complexity.

A rotatable blocker body guides a safety rope through a curved groove to allow length adjustment.

Wound cable and friction ring absorb fall energy via sliding, preventing premature deformation in compact lifeline anchors.

A descender device uses a sliding control bar within frame apertures to grip a tether for controlled descent.

Segmented thigh straps detach from a climbing harness to form a pelvic binder, reducing gear burden while stabilizing fractures.

A threaded rod with compressible elements absorbs impact energy by compressing against a bearing.

Sensor-equipped fasteners monitor harness locking status to prevent fall accidents caused by unsecured connections.
