Safety Belts TRIZ Cases

Embedding a flexible flap in a cast thermoplastic core eliminates heavy mechanical fasteners, reducing weight while maintaining reliability.

A mobile anchor cart assembly transitions between anchored and mobile positions using an axle assembly to enable rolling movement across work surfaces.

An adjustable foothold and mounting assembly enhance firefighter stability on sloped roofs, reducing slip risks caused by inadequate anchoring.

Segmentation separates the battery pack from the flexible substrate, resolving the trade-off between reliable electrical connection and ease of attachment.

Color-coded insulating layers on a safety hook reveal wear progression, preventing electric shock risks from conductive metal parts.

Pivotably coupled plates and a spring-loaded tongue lock the device onto webbing, preventing accidental detachment while maintaining ease of operation.

Integrally molding the window pane with the housing wall creates an extended seal that prevents water and debris ingress into the animal training device.

A lanyard reel cam rotates between free, waiting, and locking orientations to manage strap tension without manual lever operation.

Movable pinch bars clamp the descent line, reducing force required to release load element via intermediary tether.

A tolerance ring absorbs fall energy through friction while avoiding the high cost and complexity of plastically deformable absorbers.

A fall arrest harness suspends the wearer in a supine position using a sternal lanyard connection and rear weight distribution.

A breakaway fall indicator decouples from a brake lever to provide visual confirmation of fall events.

A modular securing aid connects to parachute leg straps via a metal ring, enabling rapid attachment to aircraft fixtures.

Pneumatic inflation replaces mechanical ratchets in this safety harness, ensuring uniform force distribution across secured loads.

An actuator releases the lap belt during side impacts while a pre-tensioner tensions both belts, biasing the occupant inward to enhance frictional restraint.

A cam portion exerts frictional force on a weighted rope against a pinching portion to secure the line automatically.

A mobile safety cart deploys a lateral spike assembly to anchor the device during worker falls.

Protruding lips in the seat belt guide reduce friction and prevent twisting during retraction.

An energy absorbing deformation portion on a fall protection mast reduces support structure damage by absorbing bending forces during user falls.

A swivel assembly uses a recessed bearing and cap to secure an axle for rotation.

A swivel D-ring attachment point prevents lanyard twisting by enabling 360-degree rotation, resolving mobility constraints in fall protection systems.

An inertia-sensitive solenoid locks the D-ring to prevent webbing bunching and ensure even load distribution across the slotted opening.

A dual-axis pawl mechanism engages guide rail stops from any fall orientation, resolving the reliability-complexity trade-off in safety devices.

A firefighter drag harness integrates a gripping loop stored within a garment pocket for rapid rescuer access.

Relocating the operation part to the base prevents gloves from getting sandwiched between the hook and closing-off body.

Segmented touch fastener links dissipate kinetic energy via controlled shear disengagement, reducing peak arresting forces on climbers.

Adjustable energy absorbing strut adapts seat belt load limiting threshold to occupant weight and vehicle speed.

A deformable pawl lockout element engages a stationary housing rib to prevent drum ratcheting caused by line rebounding after fall arrest events.

Sliding yoke connections allow independent panel movement, resolving the trade-off between structural stability and mobility in saddle hunting.

A universal continuous belay system uses a single cable web to provide smooth transitions and enhanced safety for fall protection.

An elastic cross strap forms a closed loop that tightens onto the pole during a fall, automatically engaging gaffs to resolve braking reliability issues.

A wheeled fall arrestor uses a gas cylinder to hold an arm above the surface until a tether engages a gripping plate.

An inflatable air cushion with seaming channels and valves attaches to seat belts to distribute pressure evenly across the torso.
