Earpiece/Earphone Cables TRIZ Cases

Dual minor and major windings coil existing cables or tubing into a compact shape while allowing extension without tangling or kinking.

Upper and lower tragus tabs with a universal twisted-pair cable keep microphones aligned, improving fit, directionality, and crosstalk control.

Fibers and a blunt cable feature redirect tensile and rotational loads from fragile conductors to the hearing device housing.

A blunt cable feature and anchored fibers redirect pull and twist loads from fragile conductors to the hearing device housing.

Elastic attachment portions sandwich the auricle and engage when unused, helping prevent cord tangling during carrying and ear attachment.

Integral retention members secure hearing device cables and sound tubes against movement.

This case uses elastically engaging attachment portions to sandwich the auricle and prevent cord tangling during storage and use.

A molded gasket seals wiring holes using flanges and a tapered bore to prevent fluid leakage.

High magnetic permeability spacer layers shield wire harnesses to minimize vibration noise from magnetic field interactions.

Anchor slot compresses cord segments within nested chambers to prevent tangling while maintaining portability.

Helical leadout formation eliminates bonding points that cause fatigue failures, improving mechanical reliability in miniature electro-acoustic transducers.

Capacitive yarns in an interactive cord detect twist input to replace bulky hardware buttons that corrode and break.
