Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a customized long-and-short-pin connector is used to measure distance between line cards, then the demating distance can be determined, but the method lacks flexibility and universality
Solution Approach 1:
The patent replaces the mechanical measurement approach (using physical long-and-short-pin connectors with fixed lengths) with an electrical signal-based measurement system. The measurement component sends electrical signals through the connector to detect distance, eliminating the need for customized mechanical connector structures and enabling universal application across different connector types.
Solution Approach 2:
The measurement component is designed as a universal device that can measure distances for various connector types without requiring customized connectors. The system uses standard electrical signal transmission through existing connector structures, making the measurement method adaptable to different line card configurations and connector designs.
2Measurement precision
If external test instruments or tooling are used to measure connector distance, then measurement can be performed, but the device complexity increases and real-time detection is difficult
Solution Approach 1:
The patent integrates the measurement functionality directly into the line card's existing measurement component, combining the distance measurement capability with the line card's own test equipment. This eliminates the need for separate external measurement instruments and reduces overall system complexity while enabling real-time detection during line card operation.
Solution Approach 2:
The line card performs self-measurement of the connector distance using its own measurement component, without requiring external test instruments. The measurement component utilizes the line card's existing signal cables and processing capabilities to autonomously determine the distance to the mating connector.
3Object-affected harmful factors
If the demating is narrowed to reduce crosstalk and impedance impact, then signal transmission quality improves, but the requirement for precise distance measurement becomes stricter
Solution Approach 1:
The measurement component provides real-time feedback on the actual connector distance, allowing the system to verify whether the demating meets the strict requirements needed for high-speed signal transmission. By measuring the distance through electrical signal transmission characteristics, the system can confirm that the connector spacing is sufficient to minimize crosstalk and impedance effects.
