Metal Working Apparatus TRIZ Cases

Progressive over-guard members and angled sharp blades trim beard length while reducing skin irritation and managing PFB and acne.

Independently movable razors in one shaver head adapt to contoured surfaces for more complete hair removal and wider shaving coverage.

Adjusted blade span ratios and a smaller rinse gap help a razor cartridge cut longer hair more cleanly with less trapping and irritation.

A tuned 3:1 to 6:1 blade-span ratio helps a razor cartridge cut longer hairs with less trapping and lower skin irritation.

Distributed shaving aid portions cover most of the shaving head surface to extend lubrication, improve glide, and reduce nicks and irritation.

Adjusting slice thickness by product length lets unequal food calibers form equal portions with less trimming, fewer empty packages, and better yield.

Acceleration and rotation signal patterns reveal hair-cutting events in a wet shaver using one sensor, cutting cost and saving space.

A pivoted two-part handle improves grip, shortens the cutter body, and helps avoid shoulder contact during use.

A guided pressing structure and integrated tape cutter improve paper feed stability, cutting precision, and everyday handling in one housing.

A spring-biased lock button and blade slot secure the knife closed, preventing inadvertent opening without adding bulky lock hardware.

A single-piece knife integrates circumferential and connection cuts to improve plastic cap notch precision while reducing assembly complexity.

A guided manual peeling blade prepares pipe welding areas without full circumference exposure, electrical drives, or hard-to-collect chips.

A three-part blade cuts grooves in mineral wool boards while keeping the facing attached, improving fold appearance and structural integrity.

Evenly distributed hole edges in a thermoplastic joining film improve lateral deformation, reduce hot spots, and speed ultrasonic welding.

An optically transparent retaining member guides and spreads shaver light evenly across the skin while reducing hot spots and thermal conduction.

A swing arm, locking groove, and sliding bolt keep the blade firmly locked in use while allowing smooth folding through guided motion.

A loop-shaped spring inside the movable razor assembly enables long travel pivot and ejection while reducing fatigue and permanent deformation.

A hinged enclosure isolates UV light around a detached shaving unit, enabling compact travel-friendly disinfection without eye exposure.

Integrated liquid dosing follows the cutting cycle to separate sticky slices, avoid blank-cut spraying, and reduce treatment agent waste.

A segmented blade slits facing while cutting mineral wool grooves, keeping the cover attached to reduce contamination in HVAC ducts.

Multiple hand contact points improve awareness of razor position and movement, enabling safer, more controlled intimate grooming.

A recessed blade and local vacuum let a cutting head follow uneven pallet contours for reliable automated film removal.

A movable blade carrier and guided mounting device let workers remove large slicing blades more safely and with less maintenance effort.

A raised guiding face and lower receiving face keep the blade off the rack, preventing fine particles while maintaining uniform slice thickness.

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

By shifting blade press-contact start points away from long straight segments, this case prevents uncut corner sections in endless unicursal cutting.

Handle-mounted gripping surfaces turn a pipe cutter into a lid opener, adding friction and leverage to remove stuck adhesive can lids comfortably.

Rotating sensors map each pipe’s true cross-section so the cutter can adjust penetration in real time and avoid imprecise cuts on deformed pipes.

An unlocking button and reset spring let the elastic locking plate release safely while preserving stable blade locking and plate resilience.

Mechanical claws lock into blade grooves to stop retraction and side shake, improving stability and user safety during cutting.

Localized uneven regions on the skin contact surface improve glide while limiting attachment slip for more consistent hair cutting length.

Magnetic blade tensioning replaces springs in yokeless clippers to cut friction, improve motor efficiency, and maintain consistent cut quality.

Reinforcement walls and sandwiching walls stabilize a resin cutting attachment, preserving comb spacing for uniform hair cutting.

Discrete engagement points lock the clipper attachment at selected heights, preventing slide drift and keeping hair length consistent.
