Live Contact Access Prevention TRIZ Cases
- Retractable USB Connector with Rotary Cam Mechanism
A cam-based actuator extends the USB connector for use while retracting it to prevent physical damage and cap loss.
- Rotating Protective Door for Retractable USB Connector
A rotating door mechanism retracts into the housing as a USB connector extends, maintaining full insertion length.
- Dual-Voltage Motor with Plug-Based Winding Switching
A dual-voltage motor uses a patch board and connector socket to switch coil windings between parallel and series configurations via distinct plugs.
- Hidden Connection Port Module for Thin Electronic Apparatus
A movable connection port module retracts into a housing body via a pivoting second body and push rod mechanism.
- Floating Electrical Connector with Sliding Support Plate
A floating electrical connector uses a spring-biased support plate to adjust position along guide slots for secure mating.
- Propeller Shutter Assembly for Tamper Resistant Receptacles
A propeller shutter assembly uses wing blocks and a central hub to translate vertical plug force into rotational movement.
- Rotatable Port Cover Mechanism for Electronic Device Protection
A rotatable cover mechanism guides a body to reveal or conceal input ports, protecting connectors from damage and dust while reducing visual clutter.
- Plug Locking Mechanism with Impact-Responsive Unlatching
A plug locking mechanism automatically disengages upon impact to allow the plug to retract into the housing.
- Retractable USB Plug with Elastic Sliding Mechanism
An elastic sliding mechanism automatically retracts the USB plug to prevent loss and damage without requiring a separate cap.
- MRI Connector With Displacement Unit For Reliable Contact
A connector uses a mechanical displacement unit to move contact modules for stable signal transmission.
