Pivotal Connections TRIZ Cases

Rotating bevel engagement and a spring lock simplify curved LED screen splicing while improving angle accuracy and reducing screen thickness.

A pivoting bushing fixture secures existing holes while allowing over 120° articulation for accurate alignment and smooth deburring.

An integral folded-bridge bearing applies spring force and low friction to improve torque, vibration, assembly size, and part count.

A swaged plug with an oversized-width, shallow projection locks the bearing sheet against corotation while limiting impact on ball joint characteristics.

A threaded rigid insert reinforces the ball-neck intersection to prevent ball mount breakage and keep vehicle-mounted accessories secure.

An incompressible-fluid closed cell keeps a compliant universal joint stiff during rotation while preventing buckling under compression.

Pivoting ladder assemblies nest rails into top-cap channels to switch between step, straight, and leaning modes with stable support.

A locking-button handle mechanism lets bolt cutter grips pivot to new angles without opening the blades, improving access in tight spaces.

An inverted compliant mechanism uses internal rigid members to cut flexible-member stress, resist buckling, and enable single-piece 3D printing.

Articulated turntable and trunnion joints speed vessel mooring release while maintaining secure multi-axis connection in harsh seas.

A ball-and-socket rein connector releases under excess force, then reconnects easily without adding weight or changing rein feel.

An annular resilient bumper compresses at the pivot limit to smooth pedal-to-rocker motion and reduce jerky striding on exercise equipment.

A resilient bumper in the pedal pivot damps rocker-arm motion at key angles to reduce jerky striding and improve exercise comfort.

A two-piece owl scarecrow head integrates a camera eye, motion sensor, and pan-tilt motors to simplify assembly and track nearby movement.

An oblong pivot and interrupted mounting hole let a steering column adjuster lock by insertion, rotation, and crimping, cutting assembly time and cost.

A rotary-to-linear mechanism retracts pintle pins into a tubular strut joint, improving aircraft assembly access without weakening the socket.

Four detent projections on one joint plate enable 0°, 90°, and 180° folding ruler locking with fewer recesses and lower tolerance sensitivity.

A movable positioning element marks the correct flap bearing setting, cutting iterative open-close adjustment time while ensuring full closure.

Multiple holding elements and angled extension parts keep the clip engaged under external force while remaining easy to form.

A segmented side decoration and linked hinge support cover display gaps, ease fold-state assembly, and reduce flexible display damage.

A rotatable expansion insert locks inside a coating cavity to improve fixation stability and reduce faults in mechanical assemblies.

A beveled rotating disc and spring lock adjust LED screen angles for precise arc splicing while cutting lock size, complexity, and install space.
