ToF sensing and energy harvesting preserve carriage position data, avoiding slow homing after slicer power loss.

This hair removal head uses bounded tooth tips and integrated skin supports to lift flat-lying hair while limiting irritation.

A larger skin-contact radius and smaller feeding radius help reduce injury risk on thinner skin while guiding hairs efficiently.

Non-linear cutting arrays, protrusions, and lubricating members support safer multi-directional hair removal in hard-to-reach areas.

A spindle projection engages the cap's inner protrusion to prevent sliding and synchronize angular positioning during scoring.

A pivoting lever and ramped surface convert motion into clamping force, securing the blade while enabling intuitive replacement.

This case uses segmented handle features and contoured grip points to improve razor control and reduce laceration risk.

A slicing machine retracts the product caliber during blank cuts, enabling gentler blade movement and reducing drive-unit wear.

This tile nipper uses a biased adjustment mechanism and lightweight aluminum alloy to adapt jaw spacing and reduce user fatigue.

A safety slide and pressure-held activator extend the blade laterally, while spring bias retracts it when pressure is released.

Multiple cutting arrays accommodate varied stroke directions, while protrusions and lubrication improve skin contact and shaving comfort.

Voltage sensing verifies cutter penetration before cutting, reducing material waste.

An elastic member stabilizes the fixed blade frame and reduces cutter noise.

Motion, orientation, and pressure sensing supports personalized stroke feedback while remote processing limits appliance complexity.

An opaque cartridge surface blocks ambient light so a control circuit can detect attachment and avoid unintended usage-counter resets.

A composite pad distributes cutting force in clamshell presses, reducing preparation time and noise while extending blade life.

A trapezoidal pivoting head uses dual-axis motion to keep fluid or heat openings against skin during a close shave.

This case shows how tapered and uniform-thickness blade zones shorten cutting height while reducing skin contact and friction.

Axial clamshell fasteners and locking formations stabilize a sealed motor pod while preserving blade visibility and water resistance.

This case shows how recessed blades and cage ribs improve hair cutting while protecting skin and supporting cartridge rinsability.

A continuous cutting edge and guide holes improve reproducibility when forming hand-cut components with precisely positioned holes.

A shear blade support rotates to 45°, 0°, or −45° cuts, adapting fibre tape to contours without later trimming.

Magnetic holding secures modular cutting supports on conveyor battens. Vertical removal avoids complete batten disassembly and downtime.

An inclined guiding channel and stop arrangement synchronize exposure distance settings across rotary shaver hair-cutting units.

This case uses a bendable cutting portion to conform a razor blade to facial contours and reduce irritation from repeated strokes.

Movable side guides adjust spacing and height to constrain irregular food during cutting, improving portion accuracy and throughput.

A hydrochromic adaptor signals razor dryness while its hydrophobic layer limits water absorption.

Tuned stainless steel composition and heat treatment deliver high hardness with non-oxidative acid resistance.

This shaving unit transfers rotation from the internal cutter to the external member, improving hair access without added drive components.

A detachable shaving unit uses an external drive coupling and electric actuator for effective cleaning without the main housing.

A thermal insulative blade cap uses air pockets and channels to limit heat transfer from the outer blade to the scalp.

A movable holder uses an elastic leaf, lever, and latch to replace boxcutter blades without manual holder manipulation.

This attachment uses pre-formed hair-raising grooves on both comb surfaces to support reversible use and efficient, uniform cutting.

Diagonal blade and comb elements cut stubble efficiently while minimizing skin contact risk.

A movable blade cover shifts away from the cutting edge during use to maintain user control.

A safety chopper knife pivots handles to drive the blade edge alternately toward and away from a cutting surface.
