Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a terminal block is used to connect cables in industrial control systems, then signal and power transmission are achieved, but the connection becomes loose or disconnected due to vibration and other factors
Solution Approach 1:
The pressing mechanism is designed as an elastic component that can dynamically deform and recover. When the separation member is pressed, the elastic pressing mechanism deforms to allow insertion, then automatically rebounds to generate pressing force that maintains secure connection despite vibration. This dynamic response transforms the static connection into an adaptive system that compensates for vibrational disturbances.
Solution Approach 2:
The elastic pressing mechanism provides beforehand cushioning by pre-storing elastic potential energy. Before vibration occurs, the elastic component is already in a state ready to absorb and dissipate vibrational energy through deformation, preventing the connection from becoming loose or disconnected during operation.
2Reliability
If a secure connection is achieved between terminal block and attachment connector, then connection stability is improved, but the engagement and disengagement operations become difficult
Solution Approach 1:
The elastic pressing mechanism enables easy engagement by deforming under external pressure when the separation member is inserted, reducing resistance during assembly. After insertion, it automatically rebounds to provide secure connection. For disengagement, pressing the separation member again releases the locking force, allowing simple removal. This dynamic behavior resolves the contradiction between secure connection and ease of operation.
Solution Approach 2:
The coupling member is segmented into distinct functional parts: the separation member for operation control, the elastic pressing mechanism for connection security, and the insertion groove for guidance. This segmentation allows each part to perform its specific function optimally - the separation member provides leverage for easy engagement/disengagement while the elastic mechanism ensures connection stability.
3Ease of operation
If a pressing mechanism with deformation capability is added to facilitate engagement and disengagement, then ease of operation is improved, but the device structure becomes more complex
Solution Approach 1:
The pressing mechanism is merged with the coupling member body, forming an integrated elastic component rather than a separate assembly. The pressing mechanism includes a pressing portion and a tail portion that are part of the same elastic structure, reducing the number of parts while maintaining the deformation capability for easy engagement and disengagement operations.
Solution Approach 2:
The pressing mechanism utilizes an elastic member with flexible properties, allowing it to deform under pressure and rebound automatically. This flexible design provides the necessary movement for easy operation without requiring complex mechanical linkages, motors, or additional actuating mechanisms, thereby maintaining structural simplicity.
