Portable Percussive Tools TRIZ Cases

A power tool uses a nested rubber member to reduce vibration transmission between housings through elastic shearing deformation.

A percussive setting tool uses a flexible coupling to allow transverse displacement of the receiving element.

Elastomeric shock absorbers cushion the hammer against the axial stop, reducing hand discomfort while maintaining impact energy delivery.

A tool holder base body uses a metal frame embedded in plastic to secure hand-held power tools.

An impact wrench control method estimates torque using rotational angle profiles to determine setpoint values for tightening phases.

A driving tool lift mechanism wheel moves between initial and eccentric positions to engage driver portions.

Segmented dual housing with offset air exhaust ports and restricted communication paths prevents foreign matter ingress while maintaining motor cooling.

A compact pistol grip impact wrench uses a nested frameless motor to reduce overall tool length and width.

A rotationally unitized spring and hammer co-rotate to increase effective moment of inertia within a compact impact tool drive assembly.

Beveled edges on the cap's protruding ring resolve the contradiction between connection reliability and ease of removal.

Mechanical impact sleeve dissipates idle firing vibrations via friction, eliminating viscoelastic degradation.

Segmented outer housing with detachable cover isolates the motor from dust ingress while elastic members reduce vibration transmission between housings.

Concavely curved hammer ball guidance area expands contact surface to reduce deformation and extend service life in impact wrench mechanisms.

A compression coil spring absorbs reaction forces by elastically deforming to reduce vibration in impact tools.

A brushless motor drives an impact tool mechanism while a controller adjusts rotation speed to manage dynamic weight movement.

Mechanical stop replaces hydraulic pressure control to eliminate setting variability and ensure repeatable blind rivet quality.

Positioning the vibration reducing member near the tool bit axis neutralizes high-amplitude oscillations during strong pressing operations.

A dust collecting device attaches to impact tools via a removable auxiliary handle and hose-holding unit.

A fuel cell stem receiver block uses a protective collar to shield the stem from accidental damage while accommodating dimensional variations.

A hand-held hammer redirects axial impact energy through a diversion element to generate counter-axial force.

A chisel with a twisted second working section applies rotational forces to penetrate material.

Hall Effect sensors detect magnet position in a non-contact trigger system, eliminating mechanical wear from repeated actuation cycles.

Positioning an electromagnetic clutch in a high-speed low-torque region reduces clutch size while preventing excessive reaction torque on the tool body.
