Incorrect Coupling Prevention TRIZ Cases
- Connector Lock Arm Detection Member Elastic Deformation Control
A connector lock arm uses a detection member to guide relative movement between locking positions.
- Keyed Power Connector Asymmetry Prevents Misconnection
Asymmetric keying prevents misconnection of electrical feeders, eliminating label reliance while simplifying maintenance with universal tools.
- Electrical Connector Full-Mate Indicator via Rotatable Check Member
An indicator system with a non-rotatable check member resolves difficulty detecting mating status when high torque is applied to electrical connectors.
- Hair Curler Connector With Locking Assembly
Segmented design with a universal handle reduces device complexity while maintaining electrical connectivity.
- Locking Sleeve Anti-Twist Feedback for Electrical Connectors
Anti-twist device with snap-in latch delivers tactile and auditory confirmation to resolve uncertainty during quick connection of electrical plug-in systems.
- Terminal With Elastic Nut For Torque-Limited Conductor Clamping
A connection terminal uses a nut with elastic arms to clamp conductors at a fixed torque threshold.
- Connector With Selective Noise Reduction For Branch Lines
A connector design places noise reduction members only at branch-line terminals to suppress interference while maintaining direct trunk line contact.
- Self-aligning RF Connector with Spring-loaded Centering
Spring-loaded axial movement and pivot-based tilting enable automatic restoration of the connector body to a centered position, eliminating high tilting forces.
- Electrical Plug Connector Keying Features for Voltage Safety
Asymmetric keys and keyways on plug connectors prevent mating with mismatched voltage devices.
- Circular Connector Cross-Configuration Power Signal Contacts
A circular connector uses a cross configuration to arrange power and signal contacts within an insulative housing columnar section.
- Audio Jack Grounding Contact Deflection Prevention
Auxiliary wing portion constrains grounding contact deflection in audio jack connectors, maintaining coplanar soldering and reliable waterproof sealing.
- Slim Connector Plug Using Wafer Level Alignment
Wafer level alignment structures align optical elements and fibers within a slim connector plug, eliminating wire-bonding signal degradation.
- Connector Lock Arm with Integral Primary and Secondary Lock
A connector lock arm pivots to engage primary and secondary tabs, enabling tool-free disengagement.
- Vehicle Junction Box Window for Visual Inspection
A vehicle junction box features a side wall window hole to visually check connector terminal connections.
- Electrical Connector Mating Detecting Member Locking Mechanism
A mating detecting member uses offset engaging portions to lock with immovable housing sections, preventing inadvertent forward movement in the unmated state.
- Connector Lock Portion Protection via Fitting Assuring Component
A connector housing integrates a fitting assuring component with a hollow portion to house the lock piece.
- Acoustic Connector Mating Verification
An acoustic sensor system verifies connector latching through audio signals, filtering background noise to ensure reliable mating status in noisy environments.
- Chamfered Electrical Connector Housing with Asymmetric Shielding Latch
Obtuse angled connecting edges and a spacer divide the mating cavity to prevent user mis-handling during VR connector insertion.
