Portable Percussive Tools TRIZ Cases
- Power Tool Dust Collection Box With Sealed Removable Filter
A sealed, removable filter and dust box improve dust capture, ease cleaning, and reduce vibration wear in hand-held power tools.
- Handheld Tool Gear Interlock for Safe Percussion Drilling
An integrated interlock blocks percussion drilling in the high-torque gear, preventing unsafe mode combinations and protecting the transmission.
- Ribbed Hollow Drill Bit Shaft for Straight, Lighter Drilling
A hollow core with circumferential ribs cuts drill bit weight while stabilizing rotation, improving drilling speed and hole straightness.
- Oscillating Power Tool Housing Isolation for Vibration Damping
Separated housings and dual isolation blocks cut vibration transfer in an oscillating power tool, improving stability, comfort, and cutting control.
- Power Tool Mode-Setting Unit With Integrated Plastic Selector
A one-piece plastic actuating and setting element simplifies power tool mode switching while improving reliable locking for drilling, impact drilling, and screwing.
- Electric Pulse Tool Self-Correction for Accurate Screw Tightening
Bidirectional torque pulses and sensor feedback correct over-tightening in screw joints, improving speed, accuracy, and operator ergonomics.
- Torque Clutch Locking Element for Slip-Free Drilling Mode
A transverse locking element directly constrains the transmission element to stop clutch slipping in drilling mode with low actuation force.
- Power Tool Gear Selector with Slide-Rotate Speed Shifting
A slide-and-rotate selector separates two shifting elements so power tools can change gearbox ratios more easily with less structural complexity.
- Chipping Hammer Power Control Using Lever Position and Timing
Lever position sensing and timed speed changes let a chipping hammer ramp impact power more safely while preserving effective operation.
- Chipping Hammer Handle Control for Safer Impact Energy Ramp-Up
Acceleration sensing in a pivotable handle lets a chipping hammer raise impact energy only after stable user input, improving control and safety.
- Power Tool Handle Control for Safe Speed Activation
A pivotable handle lever and sensor adjust drive speed and trigger braking when tool motion exceeds a threshold, improving chipping hammer control.
