Yielding Coupling TRIZ Cases

Offset cylindrical holes and interference pins join rotating shafts, eliminating the need for relative rotation during assembly.

Press-fit ball bearings in the spider eliminate backlash and lateral movement, reducing manufacturing complexity by standardizing trunnion sizes.

A selective torque transfer device uses a transverse slider and variable lever arm to manage rotational energy.

Resilient legs in a serpentine seal maintain contact during misalignment, preventing contamination ingress and dislodgement.

Raised projections on a connector deform hollow frame ends for tight engagement, eliminating welding and reducing labor costs.

A flexible drive coupling member transmits torque with minimal torsional deflection.

Tapered tubular sections enable axial buckling deformation to absorb collision energy while maintaining lightweight structural integrity.

Replacing standard nuts with anti-rotational bushings eliminates wrench clearance needs, allowing larger shaft diameters and higher torque density.

A flywheel assembly uses two elastic members in series to manage rotational vibrations between rotary components.

Fluid pressure regulation in a floating sub tool compensates for axial movements, reducing thread wear during drill string operations.

A generator coupling member uses segmented blocks within slots and housing openings to enable direct maintenance access.

Magnetic floating support maintains static-pressure air bearing clearance in a rotation transmitter, eliminating slide resistance from mechanical retainers.

Vacuum electron beam welding with an inner annular groove prevents air bubbles in outer joint members, eliminating burr removal steps.
