Metal-Working Apparatus TRIZ Cases

Extraction moves retention features from the rotating ferrule to the fixed handle, resolving complexity and manufacturing trade-offs.

Encoding offset data on the tip holder eliminates manual measurement, reducing replacement time while maintaining scribe line accuracy.

Angled conveyor system cuts unfrozen food using water jets, eliminating freezing steps that increase processing time.

A roller hemming method uses a segmented working roller to fold flanges into a chevron shape, maintaining tip contact with the main body.

A food slicing device uses product sensors to detect material properties and automatically adjust knife speed, feed rate, and cutting gap.

Cantilever guards prevent fingertips from reaching opposing inner surfaces, eliminating pinching hazards created by conventional protrusions.

A resilient connecting member absorbs reaction forces to suppress abnormal sounds and vibrations while maintaining swing performance.

Asymmetric keyed structures prevent incorrect assembly, maintaining orientation against torsional forces.

Segmented preloaded retainers eliminate clip buckling during manufacturing, ensuring consistent blade exposure stability and reducing assembly labor.

Thermochromic portions on razor blade supports change color to indicate temperature.

Straight cutting edges on rotating trimmer blades clip body hair with stable pressure, reducing interference noise from curved blade contact.

Positioning hair lifting frames between outer blade tops lifts body hair at small angles while preventing skin damage from high adhesion regions.

Vibratory cutting tools minimize damage to thick insulating materials, enabling precise through-hole dimensions without crushing the surrounding structure.

Micro comb slots guide hair into the cutter while gaps prevent skin wave formation and irritation.

A flexible food guard uses gripping sides and a bottom plate to hold produce securely during slicing.

Cam block and roller mechanism expands power boost range while maintaining high output force.

A staggered multilayer trimming head uses an adjusting lever to reposition moving knives for varied cutting tracks.

An integrated razor cartridge merges blades and guards into one injection-molded unit with raised ridges to prevent hair snagging during dry shaving.

A cam-driven epicyclic transmission replaces bulky eccentric wheels to balance forces, reduce noise, and shrink the operating mechanism size.

U-shaped clips interlock with handle grooves to secure removable knife scales, eliminating free play between the tang and scales.

A spacer positioned before the cutting device generates a controlled skin wave that lifts hairs for optimal engagement while minimizing skin irritation.

Replacing solvent-based wet mixing with dry mixing and pressure shaping eliminates residual voids to boost magnetic permeability and mechanical strength.
