Portable Percussive Tools TRIZ Cases
- Spring-Damper Hammer Assembly for Reduced Impact Vibration
A mass-spring-damper hammer assembly cuts impact vibration reaching the hand while preserving strike and recoil mechanics for safer use.
- Foldable Demolition Hammer Trolley With Pedal Leverage
A pedal-assisted foldable trolley carries and angles a demolition hammer to cut operator strain, fatigue, and injury risk during floor removal.
- Rotary Impact Tool Striker Sensing for Impact Energy Control
Magnetic striker position sensing enables real-time impact energy calculation, wear detection, and motor control in rotary impact tools.
- Power Tool Gear Shifting Mechanism With Spring-Locked Detents
A dual-spring selector mechanism prevents undefined shift positions in hand-held power tools, reducing gear wear and improving mode switching reliability.
- Reciprocating Tool Handle Coupling for Compact Vibration Isolation
An internal elastic coupling lets the handle and housing move relative to each other, cutting vibration transmission without increasing tool length.
- Impact Puller With Adjustable Cable Loop for Stuck Part Removal
An impact rod and adjustable cable loop let one user release stuck shafts, injectors, or ball joints without damaging nearby parts.
- Slide Hammer Tool With Flexible Loop for Stuck Drive Shafts
A slide-hammer bar with an adjustable rope loop loosens stuck drive shafts securely without extra tools or damage to nearby parts.
- Hammer Mechanism Handle Structure for Power Tool Vibration Damping
An axially movable handle with guide and elastic members cuts radial rattling and axial vibration transmission in a rotary hammer.
- Chisel Hammer Impact Assembly With Quick-Connect Sealed Anvil
A reciprocation drive and sealed anvil deliver axial impacts while limiting debris ingress and enabling quick, secure tool bit changes.
- Impact Rod Guide Geometry for Unloaded Hammer Energy Control
A stepped impact rod and guide geometry lets the rod tilt during unloading but align linearly on impact, reducing empty hammering and energy loss.
- Tool Head Coupler With Latch Collar for Secure Shaft Attachment
A grooved drive shaft, internal latch, and articulating collar secure tool heads, preventing incomplete coupling and unsafe torque transfer.
- Titanium Hammer Head Locking Assembly Against Impact Loosening
A wedge, hoop, nub, and notch interlock keeps a titanium hammer head from shifting or rotating under repeated impact.
- Cam Follower Clearance Fit for Low-Noise Reciprocating Motion
A 91-99% cam follower to track width fit creates harmonic reciprocating motion that cuts tool noise, vibration, and power use.
- Hammer Drill Handle Mount for Interchangeable Resin and Iron Bands
A grooved handle mount with adjustable band diameter lets hammer drills swap resin and iron auxiliary handles with secure retention and easy removal.
- Rotary Hammer Mode-Based Loss-of-Control Detection
Mode detection enables loss-of-control protection only when needed in a rotary hammer, reducing nuisance shut-offs while improving user safety.
- Core Drill Parallel-Axis Layout for Cordless Stand Rigidity
A parallel motor and output axis layout enables cordless core drilling while improving drill stand access, rigidity, and jobsite safety.
- Angled Power Tool Adapter for Rotary and Axial Impact Transfer
Transfers rotary motion and axial impacts through an angled adapter, letting power tool bits work effectively in different orientations.
- Front Anvil Lubrication Assembly for Impact Mechanism Wear
A front anvil lubrication path feeds grease directly to impact jaws, reducing wear and avoiding tool disassembly during maintenance.
- Impact Rod Guide Structure for Efficient Electric Hammering
A guide device shifts the impact rod from slight tilt to axial alignment, preventing repeated hammering while improving impact energy transfer.
- Tool Holder Locking Bolt Damping for Idle-Run Wear Reduction
A damping element mounted on the force transmission element cushions idle-run impact on the insert tool, reducing wear and extending tool life.
- Impact Tool Anvil Position Sensing for Consistent Torque Control
An anvil position sensor replaces torque transducers to count impacts and control motor output for more consistent torque delivery.
