Grinding/Polishing Hand Tools TRIZ Cases
- Pendulum-Suspended Knife Sharpener for Consistent Edge Geometry
A knife sharpening device uses pendulum-suspended grinding strip carriers to maintain a constant sharpening angle during operation.
- Cut and Bent Metal Knife Sharpener Plate with Offset Grip
Offset grip tabs on a cut and bent metal plate sharpener protect operator hands from blade contact while maintaining manufacturing simplicity.
- Elastomeric Media Polisher for Vehicle Surface Contaminant Removal
A hemispherical elastomeric polisher removes surface contaminants from vehicle paint using adhesive mechanical action.
- Triangular Sanding Tool with Pivoting Handle for Surface Stability
An asymmetric triangular sanding tool stabilizes operation against flipping while enabling precise corner access through a rotatable head.
- Removable Sharpening Cartridge for Knife Sheath
Segmented design resolves manufacturing cost trade-offs while maintaining consistent sharpening performance.
- Detachable Suction Plate for Plasterboard Grinding
Segmentation of the suction plate resolves the trade-off between dust extraction efficiency and handle adaptability in plasterboard grinding tools.
- Rotating Leg Knife Sharpener for Stability
A handheld knife sharpener uses a rotatable leg to increase stability, resolving the contradiction between compactness and device stability.
- Removable Sharpening Angle Guide for Multi-Knife Tools
Segmented angle guides attach to a single tool body, resolving the trade-off between fixed precision and multi-knife versatility.
