Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sliding distance in the butting direction is increased to ensure uniform butting of multiple ports, then the butting reliability is improved, but the difficulty in butting increases and the service life of the connector is reduced
Solution Approach 1:
The connector employs a floating structure where the connector body can dynamically adjust its position in the butting direction through a controlled floating distance (0.5-2mm). This dynamic adjustment allows the connector to adapt to position deviations during butting, ensuring reliable contact without requiring excessive sliding distance, thus maintaining ease of operation.
Solution Approach 2:
The patent optimizes the floating distance parameter to a specific range (0.5-2mm) to achieve the best balance between butting reliability and operational ease. This parameter optimization ensures that the connector has sufficient floating capability to accommodate assembly errors while preventing excessive sliding that would cause butting failure or reduced service life.
2Adaptability or versatility
If the sliding distance in the butting direction is increased to accommodate position deviations, then the adaptability to assembly errors is improved, but the service life of the connector is reduced
Solution Approach 1:
The floating structure provides dynamic adaptability to position deviations through controlled movement within the floating distance range, while the position limitation mechanism ensures the connector returns to its proper position after butting, preventing excessive wear and extending service life.
Solution Approach 2:
The patent incorporates a position limitation mechanism that prevents the connector from exceeding the optimal floating distance range during butting operations. This beforehand cushioning protects the connector from excessive sliding that would reduce service life, while still allowing sufficient floating distance to accommodate assembly errors.
3Reliability
If a floating function is added to allow connectors to adjust to position deviations, then the butting reliability is improved, but the device complexity increases
Solution Approach 1:
The floating structure is integrated into the connector body as an inherent design feature rather than an add-on mechanism. The floating distance is built into the connector's structure, allowing it to automatically adjust to position deviations without requiring additional complex components, thus maintaining simplicity while improving reliability.
