Shrinkage Connections TRIZ Cases

Recipe-based induction heating controls ramp rate and power for different assemblies, making shrink fitting faster, more predictable, and less damaging.

A stepped dowel and floating collar align heavy construction panels precisely, enabling fast fastening in tight, low-visibility assembly spaces.

Preformed fitting and annular protrusions fill press-fit join gaps, preventing not-joined portions and burrs in solid-phase joining.

A press-fit fastener uses object material flow into a filler portion to lock securely while allowing rapid repeated coupling and separation.

A high-conductivity liner inside the casing spreads heat across the sleeve to prevent hot spots and reduce thermal stress.

A fluted, conically tapered sleeve spreads bore pressure during interference fit, preventing substrate damage and eliminating lubricant use.

Separating the ball stud into a hollow ball and carrier part cuts machining, material loss, and surface treatment cost while maintaining wear resistance.

Laser micro-texturing on metal pins creates secure interference-fit joints with lower insertion force, less plastic deformation, and longer joint life.

Differential thermal expansion replaces fouling bolts in multi-part molds, enabling strong hot clamping and easier cooled disassembly.

Differential thermal expansion clamps mold parts without bolts, cutting fouling, disassembly effort, and mold reuse cycle time.

A low-profile tool engages a fastener from the side, then pulls it into an interference fit where angled walls and small access points block axial entry.

A multi-point snap-fit mulch plug secures to the mower deck to prevent wheel clogging and keep mulch distribution uniform.
