Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional two-surface connection mechanism is used, then the connector structure is simple, but the contact point density cannot be increased
Solution Approach 1:
The patent transitions from a conventional two-surface connection mechanism to a three-dimensional mechanical connection structure. The floatable conducting pins are arranged in multiple layers and orientations, utilizing vertical and angular dimensions to pack more contact points within the same footprint area, thereby increasing contact point density without proportionally increasing device complexity
Solution Approach 2:
The conducting pins are designed with floatable, elastic properties that allow them to dynamically adjust their positions and contact forces. This self-adjusting mechanism enables the pins to accommodate manufacturing tolerances and assembly variations, maintaining reliable electrical contact while allowing for higher contact point density in a compact arrangement
2Quantity of substance
If multiple connectors are employed to increase transmission points, then the contact point quantity increases, but the space occupied increases
Solution Approach 1:
The patent combines multiple contact point arrays into a single integrated connector housing. The first and second contact point groups are merged into one connector body, with floatable conducting pins bridging between them. This consolidation achieves the equivalent of multiple connectors while occupying less space, as the shared housing and interleaved pin arrangement maximize space utilization
Solution Approach 2:
The patent employs a nested arrangement where floatable conducting pins are positioned within cavities formed by the contact point groups. The pins are nested between the first and second contact point groups, allowing maximum packing density. This nesting approach enables more contact points to be contained within a reduced overall connector volume
3Reliability
If conventional rigid contacts are used, then the manufacturing is simple, but the electrical contact effect is suboptimal due to uneven contact heights
Solution Approach 1:
The patent changes the physical state and mechanical properties of the conducting pins from rigid to elastic/flexible. This parameter change allows the pins to deform and self-adjust to uneven contact surfaces, ensuring optimal electrical contact across all contact points regardless of manufacturing variations in contact point height or flatness
Solution Approach 2:
The floatable conducting pins possess self-adjusting capabilities through their elastic properties. When assembled, the pins automatically adjust their own positions and contact forces to achieve optimal electrical contact without requiring precision manufacturing or complex adjustment mechanisms. The pins self-compensate for manufacturing tolerances in the contact point groups
