Portable Percussive Tools TRIZ Cases

An asymmetric dust collection hood resolves visibility conflicts by rotating the hose holder and segmenting passages to prevent clogging.

Stepped sidewalls and curved engagement regions pre-align target links to ensure first-shot severing, reducing ricochet injury risk.

A tool carrier casing engagement feature prevents rotation while permitting axial movement along the operational axis.

Switching device alters spring configuration to manage resonant frequencies and reduce user fatigue in hand machine tools.

Merging separate sensors into a single unit reduces device complexity while maintaining precise control over rotational and translational movements.

Interchangeable gears and restoration springs reduce friction and component count in a hammer drill.

Internal cavities filled with dampening material extend pull force duration and reduce shock reverberation during impact.

Elongate auxiliary handle uses a fulcrum connection part to pivot the grip relative to the mounting part for enhanced vibration isolation.

A power tool attachment stabilizes wedge anchors during installation using a sliding receiver mechanism.

Guide rod transforms rotational motion into linear compression, preventing oblique loading that reduces coil spring lifespan in compact hammer drills.

A hand-held power tool motor housing uses a bearing plate to segment fastening screws, creating a slimmer profile for better ergonomics.

A control device with a selector switch automates drive motor, gearbox, and percussion mechanism settings for portable power tools.
