Metal Working Apparatus TRIZ Cases

A pliable hinge and adjustable tangs let one clipper guard fit different blade lengths, reducing guard inventory and disinfection time.

An adjustable slope and discharge port let this slicer produce longer shreds, vary slice thickness, and simplify cleaning.

Micrometric blade adjustment compensates for wear in cap weakening-line cutting, preserving precision and adapting to different cap sizes.

A pivoting, slidable cover and blade storage compartment simplify blade changes, depth adjustment, and secure blade handling.

An interposed element between razor blades creates noncutting zones that ease skin pressure, improve shaving, and keep the cartridge compact.

A sliding pin and limiting slot coordinate punch timing and ring compression to handle varied paper sizes with lower punching resistance.

A recessed comb tooth receives the guard tooth tip to limit tooth displacement, reduce hair collisions, and keep cutting length uniform.

A single mode input switches shaver speed and display states by operating context, simplifying controls while keeping key status information visible.

An upward-facing curved blade helps the razor reach the armpit recess smoothly while reducing plastic head contact and skin damage.

A dense lower cutter with U-shaped blades and curved ends boosts cutting actions while limiting bending stress and cracks.

A dual-guide blade holder lets one utility knife switch between cutting and scraping angles while staying compact, secure, and easy to use.

A rear trimmer fixed by a cap, grooves, and clip improves durability while keeping the cartridge thin for shaving under the nose and other curved areas.

A rotating disc blade cuts fragile thermoplastic pipe, then heated edge compression restores dimensions and reduces deformation.

A slit-guided paper cutter with an attached tape assembly avoids tool switching while improving cutting stability and convenience.

An angled knife handle and compact self-squaring guide cut fibrous batts and foam board with less wrist strain and better accuracy.

Attaching a lamp to each blade holder keeps blade-contact indication aligned during width changes, improving sheet cutting accuracy.

Alternating serrations and tapered recessed portions boost fixed-blade cutting efficiency while maintaining edge sharpness through abrasion.

Rolling members and a gasket cut sliding friction and heat in a shaver cutter head, improving stability, service life, and cutting comfort.

Opposite rotation of the external cutter at a lower speed with V-shaped openings improves hair capture and shortens remaining hair.

A teardrop opener with a blunt tip and hook blade slices tough blister-pack foil with less hand strain and lower cut risk.

A nested blade driver and retainer enable smooth spring-assisted deployment and retraction while keeping the blade locked in stowed and deployed positions.

A rotating support shaft and guide member combine sheet-surface travel with height change, simplifying the mechanism while improving positioning accuracy.

A higher initial blade load that tapers with travel stabilizes sheet cutting and prevents start-of-cut defects.

A spring-loaded lid leaves one razor edge exposed for precise cuts while covering the other edge to reduce finger and hand injuries.

Suspended transfer, grippers, and press bars keep printed products aligned for fast format changes and accurate three-knife trimming.

Closely spaced U-shaped lower cutter blades raise cutting actions in electric shavers while limiting bending stress and cutter cracking.

Bent razor blades, coplanar slot supports, and metal clips enable precise blade positioning changes without rebuilding cartridge mold tools.

A clamp-on guide with a conditioner reservoir helps a hair trimmer cut split ends faster and more accurately with less manual effort.

A timed secondary power-button function lets hair clippers switch motor modes without confusing display menu navigation.

Selective pneumatic branches control retractable inserts by zone, securing mixed-size dies without dislodging a previously fixed tile.

Automated cutting and sliding ejection unpack optical lenses reliably, reducing manual errors, labor, and damage before processing.

Dense lower-cutter blades with a U-shaped profile raise cutting actions per unit time while reducing bending stress and premature wear.

Suction, a collection chamber, and a self-cleaning filter capture beard residue during shaving to keep surfaces clean and simplify cleanup.

A clutch-linked foil tape mechanism synchronizes punching, pasting, and cutting to improve hole positioning and reduce punching needle wear.

A front housing cutter cuts tape separately from the retractable blade, preventing adhesive transfer while preserving safe, efficient cutting.

A four-link handle mechanism converts rotation into longer blade travel, extending the blade 2 to 3 times the handle stroke.

A plunger cam shifts from two-point to single-point contact to keep the razor cartridge stable at rest and restore it effectively during pivoting.

Small slot angles and trailing-edge hair-retaining surfaces keep hairs steady for slicing cuts, improving capture while reducing skin irritation.

An asymmetric protrusion-and-groove coupling keeps the razor handle and cartridge locked, guides correct assembly, and maintains blade orientation.

Entrapped spring biasing improves cutting blade motion while the concave neck and ridged grip help deflect debris and support steadier handling.

Pins and chutes let a scissor sheath stand upright on an edge, improving static display visibility while shielding the working part from injury.

A reversible comb attachment fits two trimmer heads with different tooth pitches, reducing kit complexity while maintaining cutting efficiency.

A lock button and limiting portion keep a push-button cutter blade locked against unintended external force until deliberate unlocking.

A single acceleration or rotation sensor detects hair-cutting patterns in a wet shaver, reducing sensor count, cost, and space.

A tuned blade span and guard-height layout helps razor cartridges cut longer hairs cleanly while reducing trapping, miss cuts, and irritation.

U-shaped blades combine cutting and stripping to produce uniform fruit and vegetable slices with cleaner edges and less waste.

Staggered blade spans, angles, and rinse gaps help a razor cartridge cut longer hairs cleanly while reducing skin irritation.

A pivoted two-part clipper body improves grip stability and handling while keeping the cutter shorter and easier to control.

Magnetic force stabilizes the blade bracket interface for smoother gap adjustment, reducing friction, wear, and inconsistency in hair clippers.

Variable slice thickness lets unequal food calibers finish together, reducing trimming waste, empty packages, and throughput loss.
