Safety Belts TRIZ Cases
- Reversible Belt Tensioner Jamming Prevention
A reversible belt tensioner uses a cylindrical guiding portion and compression spring to prevent spindle nut jamming.
- Shuttle Clamping Mechanism for Cable Guide Over Supports
A climbing shuttle uses a pivoting clamping member to grip a cable during falls while guiding movement along the support line.
- Backpack Sprayer Gravity Center Stability via Component Overlap
Vertical stacking with horizontal overlap keeps the gravity center stable as liquid decreases, preventing imbalance during operation.
- Safety Cable Support Device with Segmented Wheel for Snap Hook Passage
A support device uses a wheel with interspaced spokes to guide safety cables while allowing snap hooks to pass through unobstructed.
- Step-Bolt Adaptor for Fall Arrest Safety
U-shaped adaptor controls force application on existing anchors, preventing bending and sliding risks.
- Modular Cable Securing System for Container Edge Safety
Segmented support cables and dynamic safety ropes reduce installation time while maintaining fall protection reliability.
- Fall Arrest Sling With Progressive Seam Dissipation
Progressive seam tearing in a braking sling limits deceleration forces below 9g, preventing injury from sudden stops during variable weight falls.
- Self-securing via ferrata device with automatic locking mechanism
A self-securing stop element features a barrier that closes a recess to prevent accidental detachment from anchor points.
- Torso-Wrapping Harness with Single Abdominal Connector for Suspension Trauma Prevention
A torso-wrapping harness system uses a single abdominal connector to secure multiple straps, distributing load across the upper body.
- Single Brake Fall Protection System for Multiple Lanyards
A shared braking mechanism arrests all lifelines simultaneously upon detecting a fall, eliminating swing hazards without additional support structures.
- Universal Safe Access Head Assembly for Multi-Line Mounting
A universal safe access head assembly integrates vertical lifeline and power ascender line connectors into a single standardized interface.
- Lineman Harness Adapter Three-Point Inversion
A three-point adapter distributes weight evenly across a lineman harness to eliminate visual obstructions.
- Vehicle Belt Retractor Movable Detent for Rotation Control
A movable detent in a belt spool adjusts relative rotation between the locking disc and spool, resolving geometric constraints of fixed pin arrangements.
- Portable Fall Restraint System with Triggered Anchor Deployment
Triggered anchor deployment in this portable fall restraint system prevents accidental activation while arresting falls automatically.
