Metal-Working Apparatus TRIZ Cases

A razor shaving aid with a deformable portion reduces frictional resistance against the skin surface during operation.

A razor handle uses detachable head and tail portions inserted into a central body to simplify assembly.

Semi-cylindrical base surfaces enable safe finger holding, resolving ergonomic complexity while maintaining shaving efficiency.

Direct actuator connection via cycloidal gear improves positioning precision and feed rate control in plastic profile cutting.

A shaver head pivots on a hinge axis to follow skin contours, resolving the trade-off between adaptability and shaving accuracy along predetermined lines.

Dynamic controller adjusts guide laser power to maintain visibility while reducing energy consumption and extending operational life.

Segmented shells with a centerline rod secure the cartridge against separation while an elastomer cover enhances grip.

Converging flowpaths prevent clogging and microbial growth by displacing air from the reservoir during manual dispensing.

Segmented inclined surfaces release the head structure under rotational torque, preventing damage while distributing wear across contact areas.

Relocating the rotary control to the rear end with a worm screw transmission prevents accidental misadjustments while maintaining compact device size.

Martensitic stainless steel razor blade with bent portion resolves formability contradictions by combining parts to prevent cracking.

Safety linkage prevents blade free fall by counteracting gravity, resolving the trade-off between hydraulic actuation and operator safety.

Curved guiding surfaces on cutting blades bias hair into position, preventing trapping and improving cut quality.

Elastic annular cage engages blind hole elements via lateral prongs, preventing surface damage during strut removal.

Compact non-contact sensors integrate into food slicer working areas to detect product outer contours directly at the cutting plane.

A pet shaver integrates a shaving strip and a detachable roller with an adhesive layer to collect scattered hair during grooming.

A shaving razor integrates a pump actuated by neck pivoting to dispense fluid from a sealed cartridge directly onto the skin.

Amine dicarboxyacetone capping agents stabilize 10-22 nm noble metal clusters through steric hindrance.

A hybrid metal plate forming method combines press forming with incremental forming to shape workpieces.

Segmented stamped forging and machining processes eliminate waviness and grain growth to achieve precise variable face geometry.

A transparent conductive composite material forms core-shell nanowires with graphene shells to enhance electrical conductivity and optical transparency.
