Portable Percussive Tools TRIZ Cases

Magnetic encoder sensor chip measures anvil angle with under one degree precision to resolve torque configuration errors from low-resolution mechanical sensors.

A semiautomatic breaching tool uses a center pin ramming head to concentrate impact force for glass penetration.

Dual biasing assemblies in a two-stage trigger segment the travel path, resolving the trade-off between precise process control and device complexity.

A pneumatic percussion mechanism uses a recessed sealing element to manage airflow within the exciter cylinder.

A sensor device adjusts triggering thresholds based on motion characteristics to detect uncontrolled rotation in hand-held power tools.

A spring unit connects the handle to the main element, defining a specific movement path for vibration damping.

A swing arm transfers rotational motion to a piston, compressing a compound spring assembly for energy storage.

Non-linear spring characteristics in the counterweight extend effective damping across varying frequencies.

A portable power tool integrates a nested dust container around the motor housing with a non-coaxial fan for efficient debris removal.

A reciprocating work machine handle reduces transmitted vibration by using a high-density weight and spring to alter natural frequency.

A rotary hammer uses a single locking member to selectively lock the trigger in the ON position based on the selected operational mode.

Automating hammer activation via a servomotor gearshift resolves the trade-off between manual switching complexity and operational ease.

Flexible retaining elements compress elastic mounts to secure grips, preventing vibration transmission and protecting components from damage.

An add-on handle fastens to a hand-held power tool via an axial arrangement between the chuck and clutch setting ring.

Clamping grip with adjustable ball and socket joint reduces operator fatigue during extended tamping tasks.

Lightweight striking tool uses removable weighting material to boost impact force, resolving the tradeoff between portability and effectiveness.

Merges eccentric with second spur gear to reduce manufacturing time while maintaining balance in hand-held power tools.

A hydraulic ram attachment uses base-mounted teeth to secure grip on diverse surfaces during rescue operations.

Elastic elements decouple the hammering member from the tool body, isolating mechanical vibrations and reducing noise generated by large metal surfaces.

A hand-held power tool rotary drive uses a rocker lever coupled to an eccentric bearing to transmit torque to the guide tube.

An offset centerline reduces rear mass in a compact hammer head, enabling greater pull-back clearance in confined spaces without compromising striking power.

Segmented mandrels with diamond blades penetrate hard soil via dynamic loads, eliminating water usage and reducing construction costs.

A hammer drill adaptor captures drive cleats to transfer powered impact force for duct joining.
