Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If circuit density and complexity are increased to satisfy requirements for high efficiency and multiple functions, then productivity and functionality are improved, but signal interference increases causing abnormal operations and system failures
Solution Approach 1:
The patent creates a standard device that copies the circuit architecture of the abnormal signal device, including the same signal transmission paths and components. This copy is used to reproduce and analyze signal interference characteristics without affecting the original abnormal device, enabling fault analysis through controlled experimentation.
Solution Approach 2:
The patent introduces a fault analysis device as an intermediary system that includes a sensing circuit to detect signal distortion and a signal generating circuit to reproduce interference. This intermediary device mediates between the abnormal signal device and the analysis process, allowing systematic study of interference causes.
2Adaptability or versatility
If circuit density and complexity are increased to satisfy requirements for multiple functions, then adaptability is improved, but signal interference becomes more severe leading to abnormal operations
Solution Approach 1:
The standard device replicates the circuit architecture of the abnormal device, including all signal transmission paths and components that generate interference. This copy allows systematic reproduction of interference conditions under controlled settings, enabling analysis of how circuit complexity and multi-functionality contribute to signal interference.
3Device complexity
If no fault analysis method is used, then device complexity remains low, but the ability to detect and measure signal interference causes is insufficient
Solution Approach 1:
The patent uses a simplified standard device that copies only the necessary circuit architecture elements to reproduce signal interference. This selective copying approach maintains manageable device complexity while providing sufficient fault analysis capability through controlled reproduction of interference conditions.
Solution Approach 2:
The fault analysis device serves as an intermediary measurement system that detects signal distortion characteristics. By separating the detection function from the complex abnormal device, the system achieves improved fault detection capability without requiring complete complexity of the original device for analysis purposes.

AI summary
A fault analysis device and a fault analysis method of the fault analysis device are provided. A sensing circuit senses a first distorted signal on a first signal transmission path of an abnormal signal device when the abnormal signal device performs a preset operation. A signal generating circuit provides a fault test signal to a second signal transmission path of a standard device corresponding to the first signal transmission path when the standard device performs the preset operation, so as to generate a second distorted signal on the second signal transmission path, where the first distorted signal and the second distorted signal have the same signal distortion characteristics.
