Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the plug is made fixed and rigid, then the electrical connection is stable, but the device cannot be folded, unfolded, or rotated
Solution Approach 1:
The plug structure transitions from a fixed rigid design to a dynamic configuration where conductive terminals can be folded and unfolded along a first rotation axis, and rotated around a second rotation axis. This dynamic structure allows the plug to adapt between different operational states (folded/unfolded, rotated positions) while maintaining electrical connectivity throughout the motion range.
Solution Approach 2:
The electrical connection parameters are maintained constant despite changes in the physical configuration of the plug. The conductive elastic elements ensure that electrical contact is preserved during folding and rotation by providing continuous mechanical coupling and electrical conductivity across the moving joints, effectively decoupling the mechanical configuration changes from electrical connection stability.
2Adaptability or versatility
If the plug structure is made flexible to enable folding and rotation, then the device becomes more versatile, but the electrical connection may be lost or inconsistent
Solution Approach 1:
Conductive elastic elements are used to create flexible electrical connections that can accommodate the folding and rotation movements. These elastic elements act as flexible conductors that maintain electrical continuity while allowing the plug structure to change configuration, effectively providing both flexibility for movement and reliability for electrical connection.
Solution Approach 2:
The conductive elastic elements serve as intermediary components between the fixed housing and the moving conductive terminals. These intermediaries absorb the mechanical stress and movement while maintaining the electrical circuit, acting as a buffer that preserves electrical connection consistency despite the flexible, moving nature of the plug structure.
3Adaptability or versatility
If the plug is designed for a specific country specification, then the electrical connection is reliable for that standard, but the device cannot connect to adapter plugs of different countries
Solution Approach 1:
The plug structure is designed with universal adaptability by incorporating folding and rotation capabilities that allow it to interface with multiple different adapter plug specifications from different countries. The same basic plug structure can be configured in different orientations and folded states to accommodate various international standards, eliminating the need for multiple dedicated plug designs.
