Rotary Current Collector TRIZ Cases
- Slip Ring Wear Indication Circuit for Early Track Failure Warning
A dedicated wear indicator track and circuit detect slip-ring degradation early through electrical changes, helping prevent unexpected failure.
- Brushed Motor Brush Card Structure to Prevent Commutator Pin Collisions
A convex brush-card feature contacts the commutator first during overturning, preventing pin-to-brush impact and preserving motor reliability.
- Modular Earthing Contact Assembly for Lower-Cost Brush Holders
A separate base plate and standardized brush shaft cut machining volume, simplify assembly, and lower railway grounding contact costs.
- Rotational Electronic Hinge for Reliable Watch Band Signal Transfer
Curved conductive contacts in a rotational hinge keep watch-to-band signals connected without extra power, enabling band-based sensors and batteries.
- Concentric Electrode Connection Structure for Dense Threaded Contacts
Multiple axially movable needle electrodes contact concentric rings to raise wiring density in threaded assemblies without losing contact force.
- Windscreen Wiper Motor Brush Assembly for Precise Carbon Brush Positioning
An integrated housing activation feature aligns and releases the carbon brush to cut abrasion and keep stable collector contact.
- Concentric High-Voltage Swivel Sealing for Spark Isolation
Concentric sealed high-voltage swivels use isolated annular volumes and dielectric fluid or gas to block leakage and spark propagation.
- Cable-Winding Charger With Rotating Reel for Portable Multi-Interface Charging
A rotating pivot base, torsion spring, and conductive rings let one charger store adjustable cable length and support multiple device interfaces.
- Floating Contact Electrical Interface for Shock and Blind Mating
Multiple spring-loaded floating contacts keep plug-receptacle connections stable under shock, vibration, misalignment, and blind mating.
- Slip Ring Recess Structure for Fanless Cooling in Wind Turbines
Tangential recesses and axial openings drive self-generated airflow to cool high-power wind turbine slip rings without added fans.
- Slip Ring Buffer Structure for Slider Wear and Fatigue
A lubricant-impregnated buffer member damps slider vibration, wipes the annular electrode, and cuts wear and metal fatigue in slip rings.
- Slip Ring Assembly for Wind Turbine Yaw Power Transfer
Rotating disks and fixed conducting fingers replace yaw cable loops, maintaining generator power transfer without unwinding maintenance.
- Slip Ring RF Isolation Layout to Prevent PECVD Arcing
Adjacent slip ring channels use capacitors to balance RF and non-RF power paths, preventing breakdown and arcing in tight PECVD reactor space.
- Slip Ring Module Sealing Against Lubricant Ingress in Electric Machines
An elastic seal in the slip ring wire channel blocks lubricant ingress, preserving insulation and contact reliability in wet-running electric machines.
- Brush Module Housing for Slip Ring Dust Containment
Integrated ribs and pockets in the brush module housing capture slip ring dust to block conductive creepage paths and short circuits.
- Rotary Transformer Lubrication With Castor Oil Contact Disks
Castor oil forms a conductive boundary layer between sintered disks, cutting friction and sustaining rotary current transfer without wire interference.
- Arcuate Bearing Conductor Assembly for Raceway Current Protection
Segmented arcuate conductors and couplers divert electric charge away from bearing raceways while preserving clearance and fluid flow.
