Rotary Current Collector TRIZ Cases

Tool-access orifices in the centering portion let engineers pull out a force-fitted grounding brush while preserving shaft-current discharge protection.

Pedal-integrated force sensing uses conductive rings and contacts to transmit real-time rider input for faster, more accurate e-bike assist.

A plate-mounted adapter bracket lets generator brushes be installed and removed from the side, reducing axial disassembly, hardware, time, and cost.

Frictional ring and column contacts keep power flowing through full rotation, preventing wire twisting in rotating artificial tree sections.

Guide elements keep shaft-grounding contacts aligned during non-coaxial mounting, preventing fold-over damage, uneven pressure, and friction loss.

A spring-biased movable segment switches winding contacts without sliding, cutting wear and contact resistance to extend switch life.

A latched plug-socket with concentric ring contacts enables tool-less fixture mounting and transverse release access inside a canopy.

A less-conductive coating and capacitive channel help surgical slip rings block fluid ingress while reducing signal noise and power loss.

Raised outer walls stabilize the diaphragm pump valve housing and secure the o-ring, reducing wobble, wear, and maintenance.

Guide pins and a rotating contactor align relay terminals with connector contacts to prevent misalignment and keep electrical connections stable.

Elastic snap-fit holders lock a lightweight slipring module without a central shaft, cutting complexity while keeping a free inner bore.

A removable handle and catch arm let brush holder parts be replaced quickly while a spring monitor tracks brush wear.

An elastic intermediate element compensates for connector misalignment, enabling fast, reliable marine electrical contact under strong currents.

A sealed grounding ring diverts shaft-induced voltage from the bearing to the housing, reducing electric corrosion, noise, cost, and wear.

Rotational sensing links carbon brush length loss to angular displacement, enabling earlier replacement decisions and less electrical machine downtime.

Axially spaced ring and brush contacts with an insulative layer maintain electrical communication in rotating surgical shafts exposed to conductive fluids.

A welded spliced union gives a fixed wear reference in a brush holder assembly, helping maintain continuous electrical contact and timely brush replacement.

An externally mounted brush holder lets shaft grounding brushes be replaced without motor disassembly, cutting downtime and maintenance cost.
