Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the voltage level difference between logically high and low states is increased to improve determination accuracy, then measurement precision is improved, but the device becomes more sensitive to noise interference which reduces reliability
Solution Approach 1:
The circuit performs preliminary action by pre-conditioning the input signal through the difference-expanding device before the receiver makes the logical state determination. The device proactively expands voltage differences and suppresses noise in advance, rather than attempting to correct issues after they affect the determination process.
Solution Approach 2:
The difference-expanding device changes parameters by transforming the input signal's voltage levels through non-linear conversion. It expands the voltage difference between logical states while simultaneously compressing or suppressing noise components, effectively altering the signal's electrical characteristics to improve both precision and reliability.
2Measurement precision
If noise interference is reduced to improve signal determination accuracy, then measurement precision is improved, but this requires more complex filtering mechanisms increasing device complexity
Solution Approach 1:
The circuit merges multiple functions into a single difference-expanding device: it simultaneously expands voltage level differences, suppresses noise interference, and conditions the signal for reception. This consolidation achieves noise filtering and signal enhancement without requiring separate complex filtering circuits.
Solution Approach 2:
The difference-expanding device acts as an intermediary between the noisy input signal and the receiver. It mediates by transforming the signal characteristics in a way that makes the subsequent determination process more robust, effectively isolating the receiver from direct exposure to noise without requiring complex filtering at the receiver end.
3Measurement precision
If the voltage difference between logical states is expanded to overcome noise, then measurement precision is improved, but the conduction degree of the device must be dynamically adjusted increasing control complexity
Solution Approach 1:
The difference-expanding device performs self-service by automatically adjusting its conduction characteristics based on the input signal conditions. The circuit inherently expands voltage differences and suppresses noise through its design architecture without requiring external control signals or complex feedback mechanisms to manage conduction degree.
