Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional testing methods are used for detecting socket connections, then the testing process is simple, but the inspection coverage is limited and blind spots occur in high wire-density areas and probe-inaccessible surfaces
Solution Approach 1:
The patent introduces a sensor board as an intermediary component between the socket and the testing system. This sensor board contains sensing circuits that can detect electrical signals from the socket pins, acting as a mediator that bridges the gap between the difficult-to-access socket connections and the testing equipment, thereby eliminating blind spots in high wire-density areas without requiring direct probe access to all connection points
Solution Approach 2:
The patent transitions from direct electrical contact testing to a field-based sensing approach. By using sensing circuits on the sensor board that detect electrical fields or signal characteristics, the system moves from one-dimensional direct contact measurement to multi-dimensional field detection, enabling inspection of areas that are physically inaccessible to traditional probes
2Measurement precision
If the sensor board is disposed between the socket and fixing element to enhance inspection coverage, then the inspection accuracy improves, but the device complexity increases
Solution Approach 1:
The sensor board is designed with multi-functionality, serving both as a structural support element (fixing element) and as an active sensing component. The sensor board can detect multiple signal parameters simultaneously and works with different socket types, reducing the need for separate testing fixtures and minimizing overall device complexity despite enhanced inspection capabilities
Solution Approach 2:
The patent merges the sensing function with the structural fixing element into a single integrated sensor board assembly. By combining the mechanical support function and the electrical sensing function into one component, the system reduces the number of separate parts and interfaces, thereby limiting the increase in device complexity while achieving improved inspection accuracy
