Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate socket elements are used for power transmission and data transmission, then functional reliability is improved, but device complexity and manufacturing costs increase
Solution Approach 1:
The patent combines separate power transmission sockets and data transmission sockets into a single integrated double socket contact element. This merging reduces the total number of components and simplifies the overall device structure while maintaining the functional separation needed for reliable power and data transmission through distinct contact sections within the unified element.
Solution Approach 2:
The double socket contact element is designed to perform multiple functions simultaneously - it handles both power transmission and data transmission through its different contact sections. This multi-functional design eliminates the need for separate specialized components, reducing device complexity while preserving the reliability benefits of dedicated power and data pathways.

3Manufacturing precision
If additional adjustment measures are implemented for connecting contact pins and circuit boards, then connection precision is improved, but device complexity and installation time increase
Solution Approach 1:
The double socket contact element incorporates a self-aligning design where the first and second socket sections are automatically positioned relative to each other during assembly. The integrated structure provides inherent alignment features that guide contact pins and circuit board connections into proper positions without requiring external adjustment mechanisms, thereby achieving connection precision while reducing device complexity.
Solution Approach 2:
The socket sections are pre-positioned and pre-aligned during the manufacturing of the double socket contact element itself. This preliminary action ensures that when the element is assembled into the final device, the connections between contact pins, circuit boards, and socket sections are already optimally aligned, eliminating the need for additional field adjustments.
4Adaptability or versatility
If traditional addressing methods are used, then system compatibility is maintained, but interference immunity and digital signal reliability decrease
Solution Approach 1:
The patent replaces traditional analog addressing methods with digital signal-based addressing. By using digital square wave signals and frequency division, the system achieves higher immunity to electrical interference and signal degradation while maintaining adaptability through standardized digital communication protocols that can interface with various bus systems.
Solution Approach 2:
The addressing system uses frequency division as a key parameter change mechanism. By dividing a master clock frequency into different sub-frequencies for different bus elements, the system creates robust digital addressing signals that are inherently more resistant to interference. This parameter-based addressing maintains compatibility while significantly improving signal reliability in electrically noisy environments.
