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.

Heating the quenched steel part above its tempering temperature enables shrink fitting of a coated insert while suppressing coating delamination and extra tempering.

Laser micro-profiling textures metal pins to tune interference-fit bond strength, cut insertion force, and reduce plastic deformation.

Formable tabs lock the clutch carrier components in place while holes in the undulating ring improve cooling oil circulation and thermal management.

A recessed lug-bush groove encloses sealant from three sides, limiting crack growth while maintaining a moisture-tight barrier against corrosion.

A magnetic retaining assembly uses a ferromagnetic mounting plate to securely hold mobile devices and extensible grips without permanent modifications.

A metal joint uses segmented cut surfaces to create friction bonding between stacked plates.

Interference fit and adhesive bonding mount the cage nut, eliminating rivets to reduce weight and preserve composite structure integrity.

Radially expanding collar absorbs high forces in crusher housing connections, resolving deflection and dismantling trade-offs.

Electromagnetic forming expands an aluminum pipe inside steel components to join dissimilar metals without brittle intermetallic compounds or added weight.

Cooling an insert contracts its perimeter for insertion into a composite material hole, then expansion creates a secure mechanical lock.

A clamping fitting maintains radial force on a composite tube using differential thermal contraction between housing and wedge components.

Metallic threaded bush with coarse external and metric internal threads engages plastic cavities via frictional compression.

Plastic deformation of an expanded tube end creates a secure sleeve connection, reducing weight while maintaining torque transmission strength.

Rotatable nose cap assembly aligns mandrel with expandable member passageway, eliminating side loads and multiple angled caps.

Homogeneous aluminum inserts eliminate complex steel bushings and anti-corrosion coatings to streamline automated vehicle battery assembly.
