Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple reception circuits operate in synchronization with multiple clock signals to perform 01 determination every one-bit time, then determination accuracy is improved, but circuit scale increases
Solution Approach 1:
Multiple reception circuits performing 01 determination are merged into a single reception circuit that uses integration to accumulate signal values over one-bit time. The integration circuit combines multiple signal samples, allowing accurate 01 determination without requiring multiple parallel reception circuits, thus reducing circuit scale while maintaining determination accuracy.
Solution Approach 2:
The reception circuit performs preliminary integration of the reception signal over one-bit time before performing 01 determination. By accumulating signal values in advance through integration, the circuit prepares enhanced signal levels that improve determination accuracy, eliminating the need for multiple parallel circuits operating simultaneously.
2Stability of the object's composition
If multiple signal lines are used to input clock signals and 01 determination threshold to multiple reception circuits, then determination timing is synchronized, but circuit complexity increases
Solution Approach 1:
The single reception circuit performs multiple functions: it integrates the reception signal, detects peak points, determines 01 values, and manages timing internally through integration time control. This multi-functional approach eliminates the need for separate signal lines to coordinate multiple circuits, reducing circuit complexity while maintaining synchronized determination timing.
Solution Approach 2:
The reception circuit determines its own optimal determination timing by detecting peak points in the integrated waveform. The circuit autonomously identifies when the integrated signal reaches its maximum value and performs 01 determination at that moment, eliminating the need for external clock signals and threshold input lines to control timing synchronization.
3Ease of operation
If 01 determination is performed by comparing reception signal with threshold at constant timing, then circuit operation is simple, but noise influence increases
Solution Approach 1:
The reception circuit performs preliminary integration of the signal over one-bit time before comparison with the threshold. This preliminary accumulation enhances the signal level and averages out noise components, allowing simple threshold comparison to achieve accurate determination while reducing noise influence.
Solution Approach 2:
The determination timing dynamically adapts to the integrated waveform's peak point rather than using fixed constant timing. The circuit adjusts the comparison moment to when the integrated signal reaches maximum value, optimizing noise rejection while maintaining operational simplicity through automatic peak detection.

AI summary
On the basis of the peak point of the integrated waveform of the reception signal for each one-bit time, a timing of resetting the integrated value of the reception signal for each one-bit time and a timing of determining whether a voltage of the reception signal for each one-bit time is high or low are indicated.
