Rod Connections TRIZ Cases

Nested U-shaped subcomponents enable vibration-proof connections between frames of varying dimensions without cutting.

A nested attachment assembly uses a frusto-conical locking member to fix the position of a movable second attachment member relative to a first.

Profiled node parts join hollow profiles through friction stir welding to eliminate heat distortion and welding spatter.

A coupler with tapered clamps and threaded sleeves connects reinforcement bars securely.

A button and rotating retainer fastener secures objects to channeled members through axial slot engagement.

A plastic collapsible goal uses a tenon and mortise joint secured by an insert pin to lock poles together.

A telescoping support column with a pivoting cantilever arm adjusts speed bag height and orientation without wall mounting.

A deep drawn resonator shell uses an integral connecting section and washer to apply compressive force for secure attachment.

Spring-actuated rocker and lever mechanisms lock sports boot collars, eliminating complex cable systems that require manual assistance.

Segmented bars collapse into a vertical form, reducing space occupation while maintaining stability.

Pivoting clamping lever spreads angled clamp legs via a wedge to engage cross member undercuts, eliminating tedious bolt installation.

A vertically-adjustable bicycle saddle post assembly uses a slidable inner support and collet expansion portion for height adjustment.

Grooved clamping jaws form apertures that lock rods securely, resolving stability issues under large forces.
