Power Driven Tools TRIZ Cases

A drill-coupled interface delivers high pipe pressing or expansion force through linear jaw feed, reducing tool weight and drive complexity.

Automatic feed and programmable bending let conduit be bent precisely in confined or elevated spaces without multiple tools or extra trips.

Linear sensor feedback tracks piston travel so the controller can place crimps accurately and apply proper pressure without traditional crimp dies.

A linear sensor tracks ram movement so the controller can place each crimp correctly and apply the intended pressure more consistently.

Parallel motor and driving axes bring the motor closer to the fastening mechanism, cutting transmission loss and improving grip layout.

A rear receiving member uses the gear part's rear surface to absorb reaction force, shortening the fastening tool without losing strength.

A linear sensor tracks piston movement so the controller can adjust crimp location and pressure for consistent hydraulic crimping.

An active anvil valve and compressible bladder stabilize hydraulic damping across temperature swings and prevent pressure-driven tool stall.

Dual pawls and controller-driven repositioning return the ratchet output member to its home position for precise aperture alignment in tight spaces.

Pulsed torque, clutch cycling, and sensor feedback let an electric vise clamp quickly with one hand while avoiding sudden force and injury.

A variable-depth spindle groove and ball-supported hammer raise impact speed and force for faster screw tightening with less cam-out.

Selective and non-selective pawls manage forward and reverse torque while a home-position blocker enables smooth output member removal.

A stem-and-arm coupling lets a low-profile power head fit tight clearances while connecting to ratchet links from different manufacturers.

A compact impact tool stays within 100 mm while delivering 140 N·m maximum torque for tightening in cramped locations.

A sleeve-and-chuck adapter connects an impact wrench to rotary hammer bits, applying reverse torque to free bits stuck in concrete or rebar.

Elastic buffer units deliver different clockwise and counterclockwise torque while preserving speed and limiting fastener damage.

A gear train with bevel gears transfers torque between nonparallel axes while a through passage allows fasteners to extend completely through the device.

Controller disables motor during reverse rotation to prevent high current draw and heat generation while maintaining torque delivery.

Replacing coil springs with disk springs resolves the contradiction between increasing elastic force and maintaining low axial dimensions in impact tools.

Angled drive shaft transmits torque to a clamping nut via bevel gears, enabling tool access in cramped spaces.

An intensifier boosts hydraulic pressure from 1500 psi to 10,000 psi while isolating the heavy pump from the lightweight hand control valve.

Resin layer absorbs friction forces during mode switching to prevent excessive load on the stopper and extend component lifespan.

Segmenting the hammer mass with an auxiliary spring expands the torque range while maintaining constant impact frequency and handling stability.

Cam-controlled by-pass valve releases residual pressure in hydraulic torque impulse generators to enable rapid cylinder acceleration.

A conical spring biases the hammer away from the drive gear, allowing a nested gear assembly to maintain torque delivery within a reduced overall height.

A power tool features a motor-driven appendage that hinges and slides into its housing for compact storage.

Nested ratchet linkage and tapered side plates reduce wrench width while maintaining structural strength in confined spaces.

End cap shields drive element from dirt while reinforcing yoke arms against spreading under high load.

A friction roller drives a blind nut onto a conduit, eliminating trial-and-error positioning through tactile feedback from guide fingers.

Segmented plier projections constrain split ring ends to prevent slippage, resolving the contradiction between engagement reliability and operation stability.
