Spanners TRIZ Cases
- Adjustable Wrench Worm Gear Speed and Self-Locking
A multi-helix worm gear drives an adjustable wrench jaw for rapid movement while maintaining secure self-locking.
- Electric Torque Wrench Ring Gear Extension Arm Sensing
Ring gear extension arm integrates torque sensing unit to measure manual operating torque, resolving manufacturing complexity and component deformation issues.
- Ratchet Wrench Movable Jaw for Confined Space Operation
A ratchet wrench with a pivoting jaw and elastic clamp engages teeth to rotate in tight spaces.
- Integrated Tool Assembly with Ratchet Mechanism
A tool assembly integrates a ratchet wrench, hexagonal opener, and screwdriver into a single unit.
- Impact Wrench Control Method Using Dual Angle Sensors
Segmented control uses impact and angle sensors to measure anvil rotation, preventing screw overexpansion during steel component fastening.
- Impact Tool Control Unit for Screw Come-Out Prevention
Autonomous velocity adjustment prevents screw come-out by dynamically stabilizing hammer behavior during fastening operations.
- Pivotable Head Screwing Tool for Multi-Size Hex Nuts
Pivotable heads adjust jaw distance to accommodate various hex nut sizes, resolving the trade-off between structural simplicity and operational versatility.
- Adjustable Wrench Jaw Ratio for Tight Space Access
Optimized jaw width ratio enables secure fastener engagement, resolving tight space access conflicts.
