Drilling Accessories TRIZ Cases

A locking retainer with magnetic holding force keeps the switch secure, then reduces resistance during unlocking to prevent accidental trigger actuation.

A locking retainer and magnetic member keep trigger lockout above 20 N, then reduce force during unlocking to improve safety and handling.

A squeeze-activated grip switch lets tattoo artists power the machine without foot pedals or battery-pack switching, reducing hand repositioning and contamination risk.

By placing one spring end outside the housing, this trigger switch keeps tactile stroke and fine push adjustment in a smaller package.

A two-stage trigger and safety lever sequence prevents accidental power tool switch activation while allowing quick reset on release.

A dual-member switch uses two distinct motions to block accidental startup in powered tools while keeping one-motion deactivation easy.

A fuse-held movable contact opens under spring bias when fault current breaks the fuse, enabling rapid power tool motor shutdown.

A ratchet pawl and movable lock guide hold the trigger at discrete pull positions, enabling steady power tool speed without complex locking.

A locking switch that abuts the trigger prevents accidental power tool startup until a deliberate release-and-pull action occurs.

Axially sliding inner bearing support maintains alignment under shaft deflection while carrying thrust loads and reducing wear.

Obliquely angled bearing surfaces maintain contact during shaft deflection, preserving load support and reducing failure risk.

An inner assembly contained within an outer ring uses thrust elements and superhard contacts to handle axial misalignment and loading.

An angled planar-spheroid bearing interface maintains contact under shaft deflection, reducing failure risk in subterranean drilling.

Chemical leaching removes metal-solvent catalyst from PDC tables, improving thermal stability and impact resistance in drilling and cutting.

Oblique planar and spheroid bearing surfaces maintain contact and load support under shaft deflection and axial misalignment in drilling systems.

Oblique spheroidal bearing surfaces maintain contact under shaft deflection, helping drilling bearings tolerate axial misalignment without failure.

Geometric groove patterns on a bush inner surface trap lubricant, reduce outflow, and extend maintenance intervals without weakening fatigue strength.

Roughened bearing contact surfaces raise static friction in dental handpieces, reducing vibration, noise, and bearing wear without extra space.

A continuous superhard bearing surface paired with tilting pads cuts discontinuities, improves fluid film formation, and reduces wear and cost.

Layered superhard tilting pads maintain a thicker fluid film under high load, improving heat dissipation, wear resistance, and bearing life.

Roughened bearing-housing contact surfaces raise friction to stabilize preload, reduce vibration noise, and extend dental handpiece life.

Polished or textured superhard bearing surfaces cut friction, heat, torque, and chipping while improving load capacity and wear-in.

A rotating cable carrier and transmission assembly boost torque to tear through blockages while reducing drum wear and improving control.

A selector assembly with a shuttle moves activation buttons and circuit board switches between positions to reconfigure device functions.
