Spanners TRIZ Cases
- Strain-Gauge Electronic Torque Wrench With Remote Setting
A strain gauge measures applied torque while remote hardware sets targets and provides comparison feedback without a built-in display.
- Power Tool Strain-Gauged Torque Tube for Over-Torque Prevention
This power tool uses a strain-gauged torque tube and controller to limit torque, preventing fastener and material damage.
- Power Tool Drive Head With Torque-Switched Bidirectional Stopping
A movable stopping element switches by torque, enabling accurate tightening and loosening without sensors or added cabling.
- Multi-Mouth Wrench for Large-Angle Rotation in Narrow Spaces
This wrench combines varied mouth sizes and orientations on one rod for easier rotation and component fitting in narrow spaces.
- Electric Work Machine Optical Member for Operator Glare Reduction
Optical shielding redirects COB LED light to reduce glare and preserve workpiece visibility.
- Rotatable Tool Kit With Self-Resetting Unlocking Assembly
This tool kit uses rotatable tools and a self-resetting engagement member to simplify locking and prevent sliding during use.
- Spring-Centered Screwdriver Attachment for Offset Screw Adjustment
A linking disk and spring element compensate for radial offsets, preventing twisting and improving precise screw adjustment.
- Torque Wrench Calibration Structure for Tangential Force Control
A worm-driven guide and pivoted attachment maintain constant radial distance for torque-wrench calibration aligned with UNI ISO 6789.
- Fastener Installation Adapters for Auto-Feed Power Tools
A chuck adapter, torque transmitter, and sliding delivery attachment bring auto-feed fastener installation to common power tools.
- Clip Starter Guide for Fastener Alignment and Rotation Control
An upward funnel, barrel, recess, and handle guide clip fasteners while restraining rotation for quicker, more secure installation.
- Multi-Way Faucet Aerator Tool Combining Multiple Keys and Storage
This case merges varied aerator keys into one ergonomic tool with a lidded screen compartment and mounting support.
- Tightening Tool Torque Overshoot for Early Performance Deterioration
Torque overshoot alerts flag tightening tool deterioration before failure.
- Rotating T-Clip Installation Tool for Automatic Deck Clip Reloading
The tool feeds collated deck clips and reloads automatically when the driver bit retracts, without a motor or power source.
- Modular Multi-Tool Wrench With Separable Hinge and Self-Adjusting Jaws
A separable hinge and spring-biased sliding jaw make this multi-tool adaptable for compact repairs and scalable torque application.
- Rotatable Tool Kit With Push-Button Unlocking and Secure Storage
A movable engagement member and spring reset simplify unlocking while keeping rotatable tool members secured without sliding.
- Ratchet Tool Pawl Asymmetry for Reliable Gear Engagement
An angled pawl engagement surface creates directional bias, preventing central resting and improving reliable torque transmission.
- Adjustable Jaw Screwing Tool With Insulated Live-Work Handle
A spring-loaded head adjusts jaw spacing for screws and nuts, while insulated actuation enables safer work on live parts.
- Nutrunner Clutch Mechanism for Tool-Free Torque Threshold Adjustment
An adjustment collar, spring, and rolling elements set the nutrunner torque threshold to prevent fastener over-tightening.
- Slotted Brake Pipe Wrench with Seat-Based Tightening Feedback
A seated wrench design guides brake-pipe nut tightening, replacing depth gauges with visual confirmation before torque wrench use.
- Carbon Fiber Power-Tool Reaction Arm for Torque and Wear Resistance
A carbon fiber body with localized titanium or steel inserts balances power-tool torque resistance, wear resistance, and operator fatigue.
- Electric Tool Dual-Bearing Support for Stable Torque Transmission
Dual bearings reduce shaft eccentricity and friction for stable electric tool operation.
- Screwing Tool Torque Support with Adaptive Coupling
A two-part support foot and arm adapt to misalignment while transferring screwdriver reaction torque away from the fitter.
- Driving Head-Changeable Tool with Sliding Sleeve Retention
A blocking member and sliding outer sleeve secure polygonal ball joints during use while enabling rapid driving-head replacement.
- Bidirectional Magnetic Extractor Tool for Corner-Safe Fastener Driving
Segmented ribs avoid fastener corners during torque transfer, while a floating magnet retains extracted fasteners for reuse.
- Gearless Ratchet Tool with Spring-Loaded Pins and Low Swing Angles
Varying pin geometries, hardened materials, and springs improve torque consistency while limiting wear and swing in confined spaces.
