Key Type Connections TRIZ Cases

A keyed bracket and leg kit enables quick furniture assembly after delivery while cutting bulky leg hardware and shipping container volume.

A pivot spacer and knuckle let a handheld device mount clear nearby motorcycle components while enabling secure multi-axis positioning.

A side-mounted auxiliary contact keeps main-contact linkage while reducing switch height and avoiding assembly interference in tight cabinets.

A magnet-mounted hose guide fixes to metal surfaces so spray gun tubes slide smoothly around vehicle obstacles without constant repositioning.

A keyed internal-external lock mechanism replaces screws to speed repeated fixing and release while minimizing material wear.

Integrated latching feet and a hole-filling lock secure brackets on low-density flat panels without screws, speeding assembly and improving resistance.

Prong mounting and load-distributing channels enable tool-free curtain bracket installation with stronger wall support and less pull-away damage.

Controlled mandrel torque and contact force pre-align lithography components in vacuum while reducing particles and parasitic deformation.

A cubic metal lattice embedded in resin improves interfacial bond strength and helps relieve thermal stress from expansion mismatch.

A relief channel and locking pump handle show when tank pressure is sufficient for fine mist while preventing over-pressurization.

A protruding guide and matching recess align stacked members during screw fastening, suppressing relative shifting while improving assembly workability.

A pressure-bolt expansion assembly replaces hydraulic tensioning, enabling high clamping force and safer installation in confined bores.

Pre-positioned interference fit with mechanical vibration liquefies thermoplastic inserts for faster, more uniform anchorage with less deformation.

Radially expanding the composite rod end and locking it with a retainer secures the fitting without pre-splitting and accommodates thermal expansion.

Separate insertion, fixing, and actuating openings improve assembly access while keeping the fixing element secure and the joint stable.

A grooved non-rotating bolt clamp keeps rotary drum skinsheets tight while allowing quick loosening for cleaning and retrofit access.

A threaded cavity plus magnetic taper secures both threaded and threadless posts, enabling fast repositioning without full disassembly.

An interference fit followed by ultrasonic vibration liquefies thermoplastic material for faster, more uniform anchoring in wood or foam.

Separate insertion, fixing, and actuation openings make component assembly easier while maintaining a stable, reliable connection.

Separate insertion, fixing, and actuation openings simplify manufacture while improving access and connection stability between components.

Mechanical protrusions lock the hook plate key in the coupler slot, avoiding welding, extra fasteners, and adhesive hazards.

A two-part window sill retainer resists wind and suction loads while allowing damage-free removal without harming sealing planes.

Applying clamping force during thermoplastic insert anchoring supports porous or fibrous parts, enabling interference fit without cracks or bulging.

A movable holder with elastic pressing members removes and remounts small cartridge chips without damage, easing replacement on new cartridges.

Activatable material flows through through-holes to form a mechanical interlock, securing placement without fasteners or pre-shaping.

A locking pump handle and relief channel signal maximum tank pressure, prevent over-pressurization, and keep fine mist spray consistent.

Mechanical vibrations liquefy thermoplastic material so it flows into undercuts and resolidifies into a shear-resistant bond without adhesives.

A one-way open groove beside the fixing hole makes weld-tip insertion visible, reducing misalignment and fixation failures.

An interference fit plus ultrasonic liquefaction creates uniform thermoplastic anchorage in penetrable materials with less movement, time, and energy.

Adjustable clamps accommodate weld shrinkage misalignment, eliminating re-levelling delays during condenser assembly.

Circular arced protrusions and indentations mechanically join plates, eliminating warping from thermal processes while ensuring waterproof seals.

Eccentric annular grooves and a spiral steel cable lock components against axial misalignment and radial deformation.

Integrated valve fastening means with slits and grooves allow single-person mounting of heavy hydraulic valves without additional support plates.

A fixing device uses a guiding incline and elastic element to align and secure plates for reliable positioning.

A cargo retainer mat features interchangeable anchors that attach to the vehicle body and extend into the bed gap.
