Safety Belts TRIZ Cases

Integrating the energy absorber directly into the lanyard structure eliminates multiple attachment zones, reducing manufacturing complexity and failure points.

A lockable anti-fall catch connector uses a sliding locking shaft and resilient locker unit to secure the guiding gap.

A proximity lanyard embeds a sensor substrate within its flexible body to enable reliable detection by bucket truck anchors.

A rope fixing device anchors to building reinforcing bars using a loop fastener and case bracket for stable suspension.

Hinged front carrier portions conform to anatomical shapes, resolving the contradiction between stable helmet restraint and wearer comfort.

A belaying device uses a mobile carabiner to automatically block rope movement during sudden tension events.

A displaceable hinge uses an eccentric mechanism to lock onto a vertical rail during downward force application.

A safety harness with a front tether eyelet repositions the wearer into a sitting stance.

Segmented waist bands form a housing cavity for removable comfort foam, resolving the trade-off between user comfort and harness weight.

A ratchet-based belt retractor winds excess webbing onto a spool during installation, eliminating manual tightening and preventing loose tag ends.

Modular components including energy absorbers and clamps enable dynamic anchorage that absorbs fall forces while reducing system complexity.

A braking plate pivots a blocking part to engage a frame side surface, preventing dust accumulation and spiral spring breakage.

Segmented magnetic assembly with flexible sealant allows selective magnet replacement while cam levers protect substrates from damage.

Universal rescue strap adapts to various sizes via adjustable loops, eliminating device selection delays during transport.

A bridge rope assembly uses a splice to form an eye loop engaging a harness.

Rotatable carriers adjust wire guide positions to resolve interference between multiple cables while absorbing fall energy through deformation.

A pretensioned seatbelt retractor uses independent coupling to manage torque transmission between the spool and locking mechanism.

Vertical belt translation preserves D-ring placement for reliable fall protection.

A fall arrest safety device uses a linear energy absorber to deploy and absorb kinetic energy during a fall event.

Segmented hooks lock into tank apertures to secure lifelines, resolving two-handed installation and wall damage risks.

Movable attachment bodies grip an elongated profile to distribute fall protection loads across roof battens.

Segmented attachment element isolates the safety ring in an auxiliary loop to prevent wear and interference with the chest strap.
