Alternating blade sections and close comb teeth create gradual hair thinning, blur removal boundaries, and reduce skin discomfort.

An elastomer chuck table secures warped workpieces for consistent half-cutting.

This case replaces a volute spring with an elastic bar and dual safety mechanism to simplify assembly and control blade deployment.

A removable cutter assembly combines recessed movable surfaces, clamping, and sensing for accurate, efficient paper cutting.

A motor-driven blade assembly creates parallel cuts so carpet underlayment can be sized on-site without specialized tools.

A motor-driven blade assembly and anvil create parallel cuts, letting carpet underlayment tear to size without specialized tools.

This case shows how an aperture-and-latch connector enables removable razor handles with correct orientation and less plastic reliance.

A holder-mounted light and conductive blades preserve blade correspondence while detecting contact for precise sheet fragment cutting.

A conveyor combines incisions and mechanical spreading to separate meat from bones while minimizing poultry contamination risks.

Pre-centering guides crooked breastbones for accurate fillet cuts and yield.

A slot-and-pin mechanism, snap connection, and toothed index simplify comb assembly while delivering repeatable length adjustment and feedback.

Semicylindrical pin projections increase handle contact, reducing play while supporting tapered handles and multiple locking modes.

Rounded upper tooth tips protect skin while sharp lower teeth improve stubble capture and cutting aggressiveness.

This cutting head uses mated body segments to form knife-holding slots, reducing parts and speeding assembly and disassembly.

This mounting assembly combines fixed-axis pivoting with eccentric drive motion to keep the cutting unit aligned with skin contours.

Asymmetric tang features secure utility blades in holders, improving stability while preserving cutting edge strength and length.

This electric shaver integrates conductive cutting members as bipolar RF electrodes to reduce hotspots and provide uniform skin warming.

A vibrating component transfers motion through a structural element to clean razor cutting members without direct edge contact.

A push-button blade system combines trimming, deshedding, combing, and a protector for safer pet grooming by either hand.

This case uses an observation portion and compact outer-rotor motor to display a rotating pattern layer while reducing space and power use.

This razor cartridge uses a mechanochromic layer to show blade clogging by color change, supporting timely unclogging.

A localized recess strengthens the static cutter, reducing support parts, deformation, assembly difficulty, and material cost.

A conveyor cutting and spreading section prepares drumsticks for easier meat separation and more thorough cooking.

This case uses a T-shaped opening, I-shaped cartridge spine, detent, and grip surfaces for stable, safer blade replacement.

An intermediate-position ejector bar restrains the replaceable blade during use and enables safe, hands-free ejection.

A removable grid blade and pivotable lid deliver uniform lettuce cuts with less labor and reduced handling to limit bacterial risk.

A pressing block and interlaced blade layers improve cutting efficiency, uniformity, and hand safety for vegetable strips.

A stacked, offset blade assembly sequentially cuts vegetables into consistent parallelogram strips while reducing user pressing force.

A force-fit flexure mount self-centers the rotary scale while enabling radial adjustment with minimal feature deformation.

Skin support elements stabilize razor contact to reduce irritation during close shaving.

A partitioned razor cartridge stages hair cutting and uses guard ribs to improve rinsing, comfort, and shaving closeness.

A rigid frame with bent tabs stabilizes a flat treatment sheet for consistent skin contact and efficient hair removal.

This shaving device uses a rotatable blade cartridge and cushioned support arms to improve contour adaptation and user comfort.

A deflector and movable ejector retain the blade during use, then enable safe replacement without direct finger contact.

Magnetic coupling returns the pivoting razor cartridge to its starting position while supporting detachable, angle-adjustable shaving.

Guide edges and pressing plates align paper between opposing blades for consistent cuts and easier use by right- and left-handed users.

A recessed grip and low-profile distal handle improve pubic shaving control while helping prevent accidental cartridge ejection.

This case integrates cartridge pivots, snap fits, and a biasing member in one recyclable molded razor handle.

This case uses contoured handles, guards, and cartridge controls for precise pubic-region shaving with fewer nicks and cuts.

This case uses a textured, magnetic guard to secure both sides of a knife and shift cutting pressure away from fingers and palms.

A slit blade block uses spaced combs and a cross-comb protrusion to improve hair removal while limiting skin contact.

This knife pivot lock aligns a sliding rod with blade and frame recesses to simplify assembly and blade locking.

An 8–15° shave-plane angle and 900–1300 mm² contact area improve grip and precision for pubic hair removal.

A clamped strip-cut knife and slotted gate maintain blade alignment and slice thickness for complete cuts at high production rates.

A rotatable blade holder and safety push button simplify cutter-scraper switching while preventing accidental rotation.

An internal sliding cutting unit and rear spring cushion facial pressure, improving comfort, maneuverability, and cleaning access.
