Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the power-inlet plug is fixed to the power supply track, then the connection reliability is improved, but the ease of repair deteriorates
Solution Approach 1:
The power-inlet plug is divided into separable components: the plug body and the elastic electrical conductive member. The conductive member can be detached from the plug body for independent replacement, allowing maintenance without replacing the entire assembly. This segmentation enables easy repair of worn contacts while preserving the plug housing.
Solution Approach 2:
The locking mechanism transitions between locked and unlocked states dynamically. The elastic electrical conductive member provides dynamic contact pressure that adapts to wear and deformation over time, maintaining reliable electrical connection while allowing for easy disassembly when needed.
2Ease of repair
If the power-inlet plug is made detachable, then the ease of repair is improved, but the connection reliability deteriorates
Solution Approach 1:
The elastic electrical conductive member is pre-configured with built-in elasticity and locking features before installation. This preliminary design ensures that when the plug is assembled, the elastic member automatically provides contact pressure and engages the locking mechanism, establishing reliable connection without requiring complex assembly procedures or additional adjustment steps.
3Duration of action of stationary object
If the elastic electrical conductive member is made elastic, then the durability is improved, but the device complexity increases
Solution Approach 1:
The electrical conductive member's physical parameters are changed by introducing elasticity through material selection and geometric design. This single parameter change enables the member to accommodate wear, deformation, and misalignment over time, significantly extending durability. The elastic properties are integrated into the basic component design rather than adding separate adjustment mechanisms.

AI summary
A power-inlet plug has an installation seat, an elastic electrical conductive member and an external connector, the elastic electrical conductive member having a fixing portion and an elastic portion electrically connected to the fixing portion, the installation seat is provided with an installation cavity that accommodates the fixing portion and the external connector and a locking mechanism for detachable fix of the installation seat, the installation cavity is provided with an hole providing for the elastic portion extending out, and the elastic portion is provided with a retractable electrical contact. By setting the stop block, the permanent deformation and collapse of the shrapnel can be effectively prevented, and the problems of poor contact and contact failure can be solved. The locking part drives down the locking tongue and the power supply track extrusion locking structure design, effectively prevents the power-inlet plug from falling off.
