Metal Working Apparatus TRIZ Cases

Complex razor cartridge attachments can break under heavier premium handles; magnetic coupling adds secure retention without alignment or separate ejectors.

Opposite-corner actuator and blade placement uses pivoting motion to improve cutting convenience while limiting housing growth and safety risks.

The movable blade housing and raised second front supporter improve shaving efficiency while limiting forward-motion skin irritation.

Modular cardboard construction separates the metal blade from the razor body, supporting stable shaving and easier recycling.

A directional latch holds the slider from a defined approach, preventing unintended switching while stabilizing the pivoting working head.

A stepped pair of front supporters changes skin contact as the blade housing moves, reducing irritation while preserving shaving efficiency.

Beveled tooth tips limit vertical extension and hair deflection, helping electric trimmers cut stubble at first contact.

Controlled base-metal composition enables direct fusion joining of the cutter edge and base metal, reducing brazing cost and finishing damage.

A transverse transfer device moves the forming-tube trough to an accessible loading position before returning it for slicing.

An integrated trimmer slider activates a holding brake to lock a pivoting working head while preventing accidental configuration changes.

Bonded trenches stabilize fluorescent substances during grinding and secondary cutting, reducing chipping during LED miniaturization.

A guide-supported gouge maintains constant groove depth in thin plastic sheets, enabling precise curved and linear living hinges.

Scrap falling between breaking supports is captured in a chute and directed to a drawer, reducing shutdowns for manual cleaning.

A centered curved guide directs cut vegetables to the outlet, while detachable blade clamps ease replacement and maintain retention.

A deformable hair-contacting portion detects hair before cutting, reducing unnecessary skin contact and irritation while preserving cutting effectiveness.

An adjustment assembly slides and locks the blade inside the shank, enabling cutting, shoveling, and scraping with one replaceable tool.

Variable blade spacing lets one parallel multi-blade knife handle different cutting tasks with precise, lockable adjustment.

Exit slots in a cutting-machine impeller let rocks and other debris pass through, reducing damage to knives and knife holders.

Upper and lower scanners near the conveyor gap capture contour data while synchronized feeds limit shifting during slicing.

A locking device repositions a non-rotatable cutting element to renew multiple edges without complex blade replacement.

Directional latching prevents accidental slider changes while detent braking holds the working head at defined angles.

The supplementary-tool slider engages the holding brake to lock the working head and prevent unwanted configuration switching.

Angled placing surfaces guide hair against a recessed blade edge, helping less-skilled users control cutting angles and avoid flat cuts.

Cut hair often scatters during grooming; a negative-pressure channel and switchable head cover draw it into collection.

Two angled cutting edges share one base to support different shaving directions while improving rinsability and reducing skin bulge.

A pivotable adjuster changes cutter-to-comb clearance across blade models, improving adjustment consistency without separate model-specific tools.

Spring support keeps two blade edges against cover walls, allowing deviation compensation and reducing vibration and noise.

An open frame and parallel blades with varied lengths make Hasselback cuts quickly while preventing slices from passing through the food item.

Independent feed paths, lift trays, and optical end detection help control food-article weight, shorten reload cycles, and improve hygiene.

Plastic-and-metal disposable cartridges create waste when blades dull; this razor separates removable blades and recyclable cartridge materials for safer disposal.

Top, side, and edge perforation stations help automate complete box opening and prevent manual line stoppages.

An inner blade reverses rotation and speed to switch between cutting-quality and base-protection modes in one hair-like body cutter.

Sensor feedback adjusts the gap between the rotary die and counter-pressure cylinders to limit wear, waste, and production downtime.

An inclinable rotary blade and vertically movable reciprocating unit improve skin contact to shave long or curled hairs under the chin and nose.

A button-and-spring axis mechanism enables quick blade unlocking while keeping the folding knife concealed and reducing hand-cut risk.

A curved raised section with apertures captures hair while a pressure-relenting zone maintains continuous skin contact for close cutting.

Sliding grid plates adjust to different bread widths, helping prevent movement during cutting and produce more uniform slices.

Falling punched parts can jam or scratch on the conveyor; a shaped shoulder, widened opening, and movable ejector guide reliable transfer.

A movable compensating section and releasable lock simplify cleaning while preventing loose metal parts from remaining in the pressing unit.

Switchable blade edges and rotation speeds balance cutting quality with reduced damage to skin or fabric in an electric cutter.

Humidity and temperature can deform wooden knife components; a metal liner lock, shaft, pin, and ridged interfaces maintain secure blade locking.

Combining the stop and transverse pressing units removes a separate hold-down drive, reducing components and maintenance during slicing.

Pressure-assisted conveying holds the material web flat, limiting sagging and slippage for accurate intermittent sheet cutting.

An inclinable rotary blade and movable reciprocating blade improve contact on facial contours, preventing unshaven long or curled hairs.

A variable distance between the pressing force axis and support plane reduces torque and tilting when slicing products with different dimensions.

Multiple pushers and retainers coordinate spring-assisted deployment and retraction, reducing manual effort while securing the blade in both positions.

Large PVC pipes are difficult to position for machining; a handheld attachment bevels and deburrs the edge while vacuum suction captures debris.

Skin support surfaces help keep tooth tips from entering the hair canal while curved teeth lift and cut flat-lying hair.

The figure-8 toggle and secondary lock face keep a folding-knife blade closed until intentional user action.

Magnets hold the grooming device to the handle during operation, then release it when manual force exceeds the attractive force.
