Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional connectors and receptacles use single or double conductive terminals for electrical connection, then the device complexity is reduced, but the reliability of data and power transmission deteriorates due to misalignment or external shocks
Solution Approach 1:
The connector is divided into multiple conductive terminals (first conductive terminals and second conductive terminals) that are spatially separated and independently arranged. Each terminal can make contact with its corresponding receptacle terminal independently, so that misalignment or damage to one terminal does not affect the others, thereby improving transmission reliability while maintaining manageable structural complexity
Solution Approach 2:
Different regions of the connector are designed with different terminal arrangements - the first conductive terminals are arranged in a first region while the second conductive terminals are arranged in a second region. This local differentiation allows each terminal group to optimize its contact characteristics for specific signaling or power requirements, enhancing overall reliability without requiring complete redesign of the entire connector structure
2Ease of operation
If connectors and receptacles are frequently attached and detached, then the ease of operation is improved, but the durability of conductive terminals deteriorates due to damage or deformation
Solution Approach 1:
The connector terminals are designed with elastic properties that allow them to dynamically adapt during attachment and detachment operations. The multiple terminals can flex and return to their original positions, absorbing mechanical stress from frequent operations and preventing permanent damage while maintaining ease of connection
Solution Approach 2:
The connector structure incorporates protective features that cushion against external impacts before they can damage the conductive terminals. The distributed terminal arrangement and structural design provide inherent shock absorption, protecting the terminals from deformation during frequent attachment/detachment cycles while maintaining operational ease
3Reliability
If multiple conductive terminals are arranged to provide pressing forces in opposite directions, then the reliability of contact is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The first and second conductive terminals are arranged asymmetrically in different regions of the connector, with the first terminals in a first region and the second terminals in a second region. This asymmetric arrangement allows each terminal to apply pressing forces in different directions, creating stable contact through force balance while using standard manufacturing tolerances that do not require excessive precision
