Sleeve/Socket Joints TRIZ Cases

A spindle cavity and cam-based retention device enable one-handed bit changes in power tools.

Replacing multiple coils with a single detection coil reduces part count and manufacturing cost while maintaining precise opening amount measurement.

Radial support mechanisms constrain lateral displacement of the lifting pin, preventing contact damage to the fragile electrostatic chuck surface.

A differential screw mechanism with dual-pitch threads adjusts tool holder adapter position for precise center axis alignment.

An eccentric block drives a movable rod to actuate a spring collet, enabling quick blade changes while preventing instantaneous buckle return.

A chuck sleeve incorporates a frictional flange to enable manual rotation and joint movement with the body, resolving slippage in oily environments.

A chuck assembly uses a tightening sleeve and wedge to radially displace jaws for secure tool bit gripping.

Segmented telescopic coupling with balanced annular surfaces prevents kinking during high-pressure thermal expansion.

Divided electrostatic chuck plates maintain substrate center positioning precision while supporting large glass wafers.

Stepped notch width on a curved resilient band reduces stress concentration near bends, eliminating cracking during pipe wrapping.

A hose clamp ear features a droplet-shaped recess that captures hose material to mechanically resist radial expansion.

Segmenting primary and secondary flex elements isolates the inner components from high pressure, extending service life without increasing overall size.

A mechanically attached fitting uses interference fit to join pipes without welding.

A deformable plastic support ring closes radial gaps between the inlet connector and connection socket, preventing seal extrusion.
