Power Driven Tools TRIZ Cases
- Impact Tool Spindle Ball Mechanism for Cam-Out Reduction
Controlling impact-start torque below 1,100 N·mm prevents cam-out during screw tightening.
- Motor Front Casing Tabs for Anti-Rotation in Hand Tools
Radial tabs on the motor front casing sandwich against a rib and ratchet head housing to prevent motor rotation, eliminating elaborate assembly fixtures.
- Electromagnetic Impact Driver Using Inductor and Internal Mass
An electromagnetic inductor accelerates an internal mass to strike a rotating driver mechanism for torque generation.
