Two Pole Connections TRIZ Cases
- Tree Lamp Elastic Power Contacts for Stable Base Connection
Elastic contacts compress at the lamp-base interface to keep power stable despite slight loosening, preventing flicker and shutdown.
- Extendable Socket Collar Actuated by Plug Pins for Contact Protection
A plug pin drives a lever arm to extend the socket collar before electrical contact, reducing pin exposure and mechanism complexity.
- G-Type RF Connector Structure for High Current and 75-Ohm Impedance
A smooth-wall barrel and larger center receptacle raise current capacity while preserving 75-ohm impedance and plug compatibility.
- Tattoo Machine Power Adapter for Wireless-to-Wired Switching
A modular adapter lets a tattoo machine swap from battery power to wired supply while maintaining correct polarity and efficient power transfer.
- Electronics Jack Contact Sequencing to Prevent Premature Grounding
A movable sleeve contact and dog mechanism delay grounding until full plug insertion, preventing signal dropouts and excess current draw.
- Retractable Wall Outlet With Spooling Cord for Clutter-Free Access
A spooled extendable receptacle brings power around blocked outlets, then rewinds to prevent tangles, excess cord length, and clutter.
- Ganged Coaxial Connector Latch Retention on Pivot Post
A post protrusion keeps the latch from slipping off in a ganged coaxial connector, improving secure mating reliability and unmating stability.
- U-Shaped Plug-In Connector Assembly for Low-Height Vibration Stability
A nested U-shaped connector layout cuts circuit board assembly height while improving fastening strength and vibration-resistant contact.
- Nested Pin Assembly Structure for Compact Travel Adapters
A nested telescopic pin assembly cuts adapter width and height while supporting multiple socket standards for better travel portability.
- Multi-Receptacle Adapter Frame for Simultaneous Device Connection
Receptacles on different adapter surfaces and a sliding plug-pin assembly let multiple devices connect at once without increasing adapter size.
- Slider Connector Assembly for Wear-Free Contact Fastening
A sliding screw-driven connector keeps contacts separated during fitting, then presses them together to reduce wear and maintain reliable conduction.
- Coaxial GFCI Latching Layout for Shallow Receptacle Space
A coaxial latch inside the trip solenoid frees receptacle space while preserving reliable contact reset and trip operation.
- Slider Connector Assembly for Wear-Free Contact Mating
A screw-driven slider separates fitting from contact pressing, preventing rubbing wear and improving high-current connector reliability.
- Rotating Power Connector With Disc Contacts for Low-Friction Reliability
Overlapping disc contacts and sliding pliers cut friction and heat in rotating appliance connectors while preventing cable twisting.
- Floating Connector Assembly With Stopper Retention During Transport
A housing stopper retains the relay connector during transport, preventing accidental release and connector loss while preserving installation ease.
- AC Power Transfer Module With Mechanical No-Break Switching
A plug-in adapter and grabber switch AC sources mechanically, keeping the demand unit powered during source transfer without interruption.
- Coaxial Connector Sleeve Locking Against Accidental Decoupling
A helicoidal sleeve lock uses columnar guides and spring force to speed coaxial connector installation while preventing accidental decoupling.
- Elastic Center Contact Assembly for Stable Cable Insertion
Elastic contact arms deform during wire insertion to secure stable electrical contact while simplifying connector cable assembly.
- Electrical Connector Housing With Deflectable Walls for Terminal Retention
Deflectable latch-section walls secure multiple terminals elastically, improving retention without permanent housing deformation or added complexity.
- Rotatable Extension Plugboard for Obstructed Mounting Spaces
A 0-180° rotating plug assembly with limiting teeth and grooves helps extension plugboards fit around obstructions while staying securely mounted.
