Grinding Drives TRIZ Cases
- Fixed-Angle Sharpener with Sliding Angle Block for Consistent Blade Curves
A rotating angle wheel and sliding angle block keep the sharpening angle constant across cutter widths, lengths, and curves.
- Adjustable Pulley Belt-Disc Sander for Variable Abrasive Belt Speed
A variable-pitch pulley drive lets a belt-disc sander tune abrasive belt speed for different materials without changing motor speed.
- Angle Grinder Switching Pawl and Cam Guide for Safe Activation
A cam-guided switching pawl with a pivoting release prevents accidental angle grinder activation while keeping operation ergonomic.
- Flat-Head Grinder Screw Housing Layout for Narrow Access
A through-hole screw layout in the gear housing cuts flat-head grinder thickness while keeping bearing-box fixation secure in tight spaces.
- Offset Gear Die Grinder for Compact Speed and Torque Adjustment
An offset nested gear assembly lets a die grinder adjust speed and torque without increasing tool size or part count.
- Gear Case Grip Accessory With Dual Trigger for Tight-Space Tool Control
A palm-actuated gear case grip adds a second trigger to maintain two-handed power tool control where side handles are impractical.
- Three-Disc Polishing Head for Uniform Surface Finishing
A non-rotating outer disc with circular eccentric motion evens polishing coverage and removes appearance variations across the surface.
- Grinder Brake Assembly With Radial Pressing Members for Heat Control
Multiple radial pressing members brake the grinder shaft uniformly, cutting heat buildup, preserving braking performance, and limiting dust wear.
