Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the receiving end uses a fixed differential signal processing method, then the signal reception reliability is improved for differential signals, but the adaptability to different signal input modes deteriorates
Solution Approach 1:
The patent implements dynamic adaptability by using a control circuit that automatically detects the signal input mode (differential, single-ended, or in-phase) and dynamically switches the signal processing method accordingly. The control circuit counts signal edges within a preset time period to identify the input mode, then selects the appropriate processing path, enabling the receiving end to adapt to different signal types without manual configuration.
Solution Approach 2:
The patent changes the processing parameters based on the detected signal mode. For differential signals, it uses differential processing; for single-ended or in-phase signals, it converts them to differential form first. The control circuit adjusts the signal processing parameters dynamically according to the counted signal edges, ensuring optimal reception reliability for each signal type.
2Adaptability or versatility
If the receiving end uses adaptive signal processing to handle multiple signal modes, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The patent segments the signal processing function into distinct modules: a control circuit for mode detection, edge counting logic for analysis, and separate processing paths for different signal types. This segmentation allows each module to perform its specific function independently, making the overall complex system manageable and maintainable while achieving multi-mode adaptability.
Solution Approach 2:
The control circuit acts as an intermediary between the input signal and the processing paths. It detects the signal mode and directs the signal to the appropriate processing path, simplifying the overall architecture by centralizing the decision-making logic rather than requiring multiple parallel processing systems for each signal type.
3Device complexity
If the receiving end uses simple signal processing, then the device complexity is reduced, but the signal reception reliability deteriorates for non-differential signals
Solution Approach 1:
The patent performs preliminary action by detecting the signal input mode before processing the signal data. The control circuit counts signal edges within a preset time period to identify whether the input is differential, single-ended, or in-phase, and prepares the appropriate processing method in advance. This preliminary detection ensures that the correct processing path is selected, preventing reception errors before they occur.
Solution Approach 2:
The control circuit serves as an intermediary that automatically selects the appropriate processing method based on signal mode detection. This intermediary function adds minimal complexity while ensuring high reliability, as it prevents misprocessing of non-differential signals by routing them through the correct processing path based on edge counting analysis.

AI summary
A signal receiving device adapting to a signal input mode and a signal processing method for the same are provided. The signal receiving device can determine various signal input modes, such as a differential signal or a single-ended signal, and select an appropriate signal source, such that the signal receiving device can not only receive the input signal correctly, but also adjust the received input signal to a differential signal with the same amplitude and opposite phases to make subsequent data analysis work easier.
