Portable Power-Driven Tools TRIZ Cases

A curved deflector attachment redirects the drilling needle at an offset angle, making ground-level and overhead drilling easier without complex setup.

Material recesses in a planet carrier shaft cut weight, hold lubricant, and simplify relubrication and gear-mount machining.

Selectable trigger-linked speed caps and planetary gearing reduce bit wear in steel drilling while preserving torque and controllable output speed.

A threaded shaft turns drill rotation into axial blade travel, enabling fast cutting of rods and pipes without a dedicated cutter.

Elastic holding brackets join tool gear housings through housing openings, saving space while keeping the connection secure and serviceable.

A rotary-to-ratchet transmission lets standard power tools drive a removable pipe cutting head for faster, more versatile tubular cutting.

A rotating brush dust box captures overhead drilling debris while a rail-and-clamp depth stop sets precise bit penetration.

A handle-mounted dust collector keeps the hammer drill center of gravity closer to the grip, reducing hand load while maintaining stable dust collection.

A single motor with two output shafts replaces dual motors in a rivet nut machine, enabling adjustable gear ratios and simpler parameter input.

A removable collar attachment mechanically presses the trigger while a radio receiver enables remote hand tool use in hard-to-reach areas.

Rotating projections and a position-dependent lock replace threaded joints, enabling fast module detachment without sacrificing connection security.

Motor fault detection triggers reverse, pause, and resume steps so a pressing tool can re-press PEX tubing with less delay.

Selectable output speed limits keep drilling speed controlled on steel plates, reducing bit wear and extending bit service life.

An attaching hole built into the front case secures the holding tool while reducing machine size and simplifying one-handed attachment.

A controller records trigger-driven motor behavior, including stop intervals, then replays it for more consistent and efficient power tool operation.

Material recesses in the intermediate shaft act as lubrication pockets and weight-saving features for planet wheel bearing points.

A second actuating element enables the transfer linkage only when pressed, preventing drop-induced trigger force from damaging the first actuator.

An interface member with multiple isolators decouples the battery pack from housing vibration, extending battery life in power tools.

An offset lower guide and telescoping nozzle improve sliding accuracy, protect exposed parts, and keep dust collection effective in tight spaces.

A removable cuff with handling extension enables radio-based hand tool actuation in hard-to-reach areas without complex setup or tools.

Adjustable clamps engaging housing notches let one dust collector mount securely across rotary power tool sizes while maintaining collection efficiency.

A movable selector, pivoting yoke, and neutral-bias springs enable smoother gear ratio switching with lower part count in a multispeed power tool.

A nested control ring, C-shaped ring, and balls lock the pivoting tool head without a protruding knob, improving grip comfort and appearance.

An interlocking jaw assembly with a spring and locking pin balances cutting forces, reducing binding, bending, and tool weight.

A radial cam and shuttle mechanism controls wire cutting force and auto-retracts the blade to ease insertion and prevent jamming.
