Rotary Current Collector TRIZ Cases

Galvanic deposition of a roughened copper layer propagates surface texture through nickel and gold plating to form low-noise slipring contacts.

Selective gold coating on metal wire reduces manufacturing cost while maintaining low electrical resistance.

Segmented slip-rings on intermediate shrink rings enable radial cooling air flow, resolving the trade-off between mechanical strength and heat dissipation.

A foldable electrical plug connector features a rotary assembly and linkage mechanism for independent ground prong rotation.

Angled circuit board groups on a single carrier enable compact assembly of rotary transmitters while redundant contact points maintain low current density.

Rubber dampers sandwiched between the shaft and housing eliminate end play, preventing worm gear damage from axial vibration.

A pivot plug connector uses a pivoting member and rotating member to adjust its orientation.

A rotatable electrical connector enables continuous data transmission between patient sensors and monitors through dynamic rotation.

A dual-purpose lock member with interlocking legs secures rotating and fixed components during assembly.

Sealing rings and polytetrafluoroethylene elements prevent dust accumulation in DC motor commutators, reducing spark risk.

A test point adaptor uses a conical outer sleeve and sealing member to maintain electrical continuity during sliding engagement.

Friction-enhancing material on the brush spring allows safe single-handed replacement, reducing downtime and electrical contact risk.

An axial support pillar positions the brush holder perpendicular to the axis, reducing radial size while maintaining joint stability.

A resilient support member maintains electrical contact quality in surgical slip rings despite component fatigue.

A spring stop post limits radial movement of a torsion spring leg to prevent disengagement during drops and maintain commutator contact.
