Yielding Coupling TRIZ Cases

An electromechanical disconnect in a CV joint cuts wheel-end assembly complexity and cost while preserving torque transfer and power-loss operation.

By combining clutch members on one output shaft, this case cuts reverse torque while reducing bearing count and motor axial length.

A localized weak section in the stub shaft shifts torsional failure away from the sleeve yoke, helping prevent lubricant leakage.

An offset tightening member keeps a compact axle bearing accessible, enabling smaller differential packaging and easier mounting.

A radially pretensionable element and conical surface keep hub and CV joint teeth aligned during blind assembly, preventing pretension loss.

An asymmetric boot groove on the propeller shaft reduces boot expansion during insertion while keeping secure mounting and sealing.

A centered spline joint and flange-spacer clamp reduce propeller shaft vibration and bolt loosening in a 4WD transfer output shaft.

A releasable axial lock and guide portion let coaxial shafts compress or elongate in a crash while maintaining alignment and absorbing deformation energy.

A smaller outer-race centering portion keeps CV joint alignment accurate while reducing transmission or differential interface size.

Shaping radii smooth burr-prone tooth transitions, guide material flow, and form sharper spur toothing tips for safer assembly and higher load transfer.

A segmented rotation linkage replaces a costly universal joint to transmit motion across non-coaxial antenna motor and phase shifter layouts.

An extension portion, boot, and band secure the CV joint hub assembly, improving sealing and preventing boot escape and contaminant ingress.

A generator fixed inside the shaft body cuts external space and dust exposure while enabling induction-based power generation and stress sensing.

Vibration-absorbing drive couplings and sound-dampening valances cut motor assembly noise in architectural coverings while reducing wear.

Matched helical toothings cancel axial loads in a plug-in stub shaft, cutting bearing complexity, friction, and axle disassembly effort.

Universal-joint drivetrain and rubber supports let mobile generators tolerate misalignment, cut realignment time, and improve transport balance.

A spur-tooth plug coupling transmits torque while compensating shaft misalignment, enabling compact automated motor-gearbox assembly.

Integrated sealing and adjustable damping make the strut quieter, more durable, and easier to adapt across tailgate projects.

Separating radial load support from torsional damping boosts axle-suspended motor coupling capacity, service life, and maintenance ease.

Bevel gearing between the hub body and freewheel body cuts wear, raises torque capacity, and reduces hub size and maintenance.
