Rotary Current Collector TRIZ Cases
- Spin Chuck Pin Retraction for Uniform Substrate Liquid Films
A movable chuck pin retracts during substrate rotation to stop liquid flow-down and preserve etch film uniformity and selectivity.
- Rotatable Electrical Interface for Lift Unit Power During Rotation
A slip ring in the rotating lift assembly keeps power flowing during rotation, avoiding cable twist and eliminating charging interruptions.
- Planar Slip Ring Structure for Coaxial Rotation Stability
Radially symmetric extension sections and aligned contact points keep planar slip rings coaxial, reducing wear and stabilizing rotation.
- Brush-Commutator Aging for Low-Noise Motor Assembly
Pre-assembly high-speed aging forms a carbon layer on the commutator, stabilizing brush contact and reducing motor noise and current ripple.
- Plug-In LRU Motor Sensors Without External Corrosion-Prone Cables
Internal wireways and a plug-in LRU sensor socket remove exposed motor cables, cutting corrosion, contamination, and maintenance downtime.
- Wind Turbine Grounding Circuit With Self-Cleaning Sliding Contacts
A cleaning current through multiple sliding contacts prevents insulating film buildup, lowering impedance and electromagnetic noise in wind turbine grounding.
- Foldable Rotating Plug Structure With Stable Electrical Contact
Conductive elastic elements keep plug terminals electrically connected during folding and rotation while supporting adapter compatibility across countries.
- Slip Ring Brush Holder Structure for Insulated Brush Guidance
An insulating guiding member and conductive contact structure improve brush guidance, enable easy replacement, and prevent slip ring flashovers.
- Brushed Motor Constant-Load Spring for Stable Brush Pressure
A dual-spiral constant-load spring keeps brush pressure stable as wear progresses, cutting friction variation and extending motor life.
- Adjustable Carbon Wear Tester for Precise Brush Monitoring
An adjustable trigger and signal generator enable precise carbon brush wear monitoring on conductor lines with minimal space and less downtime.
- Motor Terminal Connection Structure for Vibration-Stable Soldering
A lid-covered bracket projection with solder gaps reduces motor vibration transfer and stabilizes substrate-to-terminal connections.
- Rotating Pipeline Camera Assembly for Dead Zone-Free Inspection
An inclined optical axis and motor-driven rotating mount expand pipeline camera coverage to remove blind spots in complex inspection paths.
- Rotatable Electrical Connector With Internal Contacts and Secure Mating
Internal plug contacts, spring-loaded retention arms, and connection sensing enable safe omnidirectional mating with smaller incisions.
- Carbon Brush Wear Monitoring Using Angular Displacement Sensing
Angular displacement sensing tracks carbon brush wear in real time, enabling timely alerts and maintenance before slip ring faults cause downtime.
- Commutator Motor Brush Assembly With Spring-Arm Pre-Clamping
A flexible spring arm pre-clamps the carbon brush and cable to avoid commutator collision, cut assembly rejects, and tolerate slot variation.
- Concentric Electrode Connection Structure for High-Density Threaded Wiring
Axially movable needle electrodes contact concentric rings to raise wiring density and simplify electrical connection between threaded members.
- Rotating Sheath Cable Structure for Mobile Vehicle Connections
Separated sheath segments and a rolling bearing let the cable rotate between movable vehicle devices while keeping electrical connection simple.
