Rotary Current Collector TRIZ Cases

A sintered power supply brush contacts a rotating electrode roller shaft through a specialized non-conductive lubricant layer.

Mechanical vibration breaks static friction between wire contacts and grommets, resolving tolerance stack-up misalignments that cause high failure rates.

A resolver stator terminal pin uses a longitudinal fold to create a double-layer structure for enhanced mechanical strength.

Axial slip ring extension increases heat transfer area within the rotor shaft recess, overcoming limited thermal dissipation from insulating carriers.

Recessed channels in commutator inner layers capture excess flux and air, preventing trapped voids that weaken solder joints and cause edge chipping.

A segmented housing uses pneumatic pressure and dual-stage suction to capture carbon dust, preventing contamination that compromises machine reliability.

Longitudinal lead bars on a collector shaft distribute torque to reduce torsional stress concentration in the main shaft.

Brush body with spaced detection zones of varying electrical resistance enables accurate wear measurement through voltage monitoring.

A drill collar connector uses rotatable male and female joints with multi-core coaxial electrical connectors for reliable signal transmission.

Spiral antennas transfer electric power wirelessly across rotating joints, eliminating slip ring wear and spacer eddy current losses.

A unitary rotary joint uses plateable and non-plateable resins to create integral conductive pathways via electroless plating.

Controlled-impedance transmission lines minimize waveform distortion in high-frequency signals, enabling reliable multi-gigabit data transfer.

Segmented conductors with distinct surface areas prevent unintentional power transfer in downhole tools by isolating high-power paths from low-power signals.

An insulating barrier prevents parasitic discharge between conductive rings, ensuring stable rotation and uniform etching.

Decoupling the elastic spring carrier from precious metal contact pieces reduces material costs while maintaining reliable conductive connections.

Adjusting carbon particle diameter to 300-2000 micrometers reduces electrical resistivity without increasing friction or wear.

A pivoting mechanism uses a rotary unit with a slot structure to provide stable support during rotation.

Segmented wear counters linked to an angular encoder detect non-uniform brush wear in discontinuously rotating industrial robots.

Porous slip ring track stores lubricant within cavities sealed by a top coating, preventing brush floatation and maintaining low contact resistance.

Cage fingers capture coiled spring ends to prevent disconnection and electrical short circuits in high voltage motors.

Resin molding integrates external connector terminals with a common base group, eliminating soldering and welding processes to reduce manufacturing complexity.

Merging housing and base into one component eliminates tolerance accumulation and rattling between separate parts.

A contact-type power supply apparatus uses a sliding cylindrical body to transfer electric potential across rotating interfaces.

Asymmetric teeth on the rotating shaft and fixed fluted disk prevent perpendicular gravity orientation, maintaining optimal heat dissipation angles.
