Engineering Contradiction Analysis
1Measurement precision
If traditional measuring instruments like oscilloscopes are used, then measurement precision can be achieved, but device complexity and difficulty of operation increase due to specialized knowledge requirements
Solution Approach 1:
The patent uses a communication signal as a copy or proxy for noise measurement. Instead of directly measuring noise with complex instruments, the system transmits a known digital signal through the communication wiring and detects code errors in the received signal. This copying approach simplifies the measurement process while maintaining precision, as the code errors directly indicate noise interference without requiring specialized oscilloscope operation.
Solution Approach 2:
The patent replaces the mechanical/probe-based measurement system with an electronic signal-based system. Instead of using physical probes that require manual installation and specialized knowledge, the system uses automated digital signal transmission and error detection through communication wiring, significantly improving ease of operation while maintaining measurement capability.
2Measurement precision
If probes are installed on measurement targets, then local measurement precision is improved, but adaptability decreases due to substrate modification requirements
Solution Approach 1:
The patent makes the measurement system universal by using communication wiring that already exists in the system rather than requiring probe installation on specific measurement targets. The communication signal can traverse any communication wiring in the system, allowing the same measurement apparatus to measure noise at multiple locations without modification, thus achieving both precision and adaptability.
Solution Approach 2:
The patent introduces communication wiring as an intermediary medium for noise measurement. Instead of directly contacting measurement targets with probes, the system uses the existing communication wiring infrastructure as a mediator to carry the measurement signal, eliminating the need for substrate modification and enabling versatile application across different measurement points.
3Measurement precision
If local measurement is performed, then measurement precision at specific spots is improved, but productivity decreases due to inability to measure wide range efficiently
Solution Approach 1:
The patent merges multiple measurement capabilities into a single system. By transmitting digital signals through communication wiring that spans multiple locations, the system can simultaneously or sequentially measure noise at multiple spots without requiring separate measurement instruments or probe installations for each location, thus improving productivity while maintaining precision.
Solution Approach 2:
The patent enables continuous measurement across the system by using communication wiring that continuously connects different parts of the device. The digital signal can be transmitted and measured at various points along the communication path without interruption, allowing efficient wide-range noise assessment while maintaining spot measurement precision.
