Rotary Current Collector TRIZ Cases
- DC Motor Sheet Plate With Separate Brush Holder
Separating the brush holder from the sheet plate resolves heat deformation and pigtail damage risks while simplifying installation in narrow spaces.
- Steering Column Rotary Connector Liquid Barrier Design
A steering column cover integrates a peripheral dam portion above the rotary connector to block fluid ingress paths.
- Brush Holder Fixation via Bridge Portions and Fitting Grooves
Bridge portions insert into fitting grooves on a thick-wall portion to distribute load, improving bending strength without increasing DC motor weight.
- Electrical Conduction Mechanism for Sheet Metal Pullers
A shaft-integrated conduction mechanism uses a spring-biased chip to supply current to the bit.
- Projection Linkage Mechanism for Automatic Mode Switching
A linkage apparatus drives a direction change mechanism to adjust light ray orientation based on device arrangement.
- Rotary Connector Liquid Metal Contact Resistance
Liquid metal fills the clearance between rotating and fixed electrodes to eliminate point contact wear and reduce resistance heat.
- Carbon Silver Copper Brush for Sliding Electrical Contact
A carbon silver copper brush layer maintains electrical conductivity and mechanical strength.
- Expandable Catch Protective Device for Electric Drive Mounting
A protective device shields the expandable catch means of an electric drive snap-on connector to prevent unintended expansion.
- Wind Turbine Hub Electrical Switch for Wear Reduction
A wind turbine hub switch connects nacelle and rotor power circuits only when the rotor is stationary.
- Conductive Dynamic Seal for EMI Suppression in Rotating Turrets
Segmented conductive strips embedded in an annular base bridge open Faraday cage volumes to suppress electromagnetic interference in rotating turret systems.
- Armature End Insulator Stepped Teeth Wire Packing
Stepped insulating teeth guide conductive wires for compact routing, resolving low slot fill and suboptimal packing efficiency in power tool motors.
- Rotating Vacuum Chamber Coupling Assembly for Bias Voltage
Ball bearing coupling conveys bias voltage to rotating platen, reducing maintenance needs and operational costs.
- Combined Insulator Conductor Assembly for Bearing Current Protection
An annular insulator with a fixed conductive disk and brush subassembly prevents current flow through the bearing while providing an alternative path.
- Propeller Deicing Brush Block Arcing Prevention
Insulated wires secured by terminal studs replace bare copper buss bars to prevent arcing damage from oil contamination.
- Unitary Molded USB Device With SIP Module
Batch molding multiple SIP modules on a panel reduces manual assembly complexity while maintaining high throughput and reliability.
- Brush-Slip Ring Cooling and Abrasion Removal System
A gaseous medium flow creates a vortex to contain abrasive particles, resolving the trade-off between cooling efficiency and carbon dust spread.
- Slip Ring Fan Insulating Segment Cooling
Shaped insulating segment forms a fanwheel to distribute cooling air flow through slip ring boreholes.
- Brush Holder Thermal Protection via Deformable Insulator
A brush holder uses a deformable insulating layer to trigger short-circuit protection during overheating events.
- Rotatable Device Brush Contact Eliminates Wire Tangling
Stationary power supplies paired with rotating brushes eliminate wire tangling and reduce motor loads, extending service life.
- Rotatable Connector Gap Design for Foreign Object Protection
An offset stator rim shields the accommodation space, preventing cable breakage and short-circuiting from foreign object intrusion.
- Rotating Connector Module for Reliable Electrical Contact
A connector module with a rotating element maintains electrical contact within a casing.
