Spanners TRIZ Cases
- Power Tool Position Locking for Screw Joint Quality Control
A control device locks power tool operation at the exact position of an unacceptably tightened screw joint.
- Pneumatic Tool Torque Control via Dynamic Air Pressure Regulation
Dynamic air pressure regulation minimizes localized heating and eliminates tool overrun, enabling precise torque stopping at specified loads.
- Unidirectional Ratchet Wrench Control Plate Design
Sheet metal control plate integrates pressing edge and elastic element mounting to eliminate welding steps and reduce manufacturing costs.
- Orientation-Independent Wrench for Underground Stop and Waste Valve
Segmented jaws and anti-stiction bypass areas engage eccentric handles, reducing friction during insertion.
- Illuminable Picker Integrating Bulb and Expandable Claw
Integrating a bulb within the tube structure allows single-handed operation, eliminating the need for a separate flashlight.
- Landing Gear Axle Nut Safety Socket Trigger Mechanism
Trigger mechanism disengages torque when axle-to-nut distance indicates missing washers, preventing improper installation.
- Wrench Assembly Segmentation and Nesting Mechanism
Segmented wrench members nest via a switch mechanism that locks components together, reducing structural complexity while maintaining reliable torque transfer.
- Bi-acting Ratcheting Driver with Switched Pawl Mechanism
A bi-acting ratcheting driver uses a switch to engage cooperating pawls with dual ratchet gears for reversible operation.
- Powered Screwdriver Tool Holder with Bent Hex Key Retention
A powered screwdriver tool holder accommodates screwdriver bits and bent hex keys using a specialized retainer system.
- Adjustable Wrench With Three-Jaw Grip and Quick-Release Mechanism
An adjustable wrench with a toothed ramp and dual actuators enables rapid jaw repositioning for efficient fastener engagement.
