Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate signal lines are used to transmit different information to functional units, then each piece of information can be transmitted reliably, but the number of signal lines and device complexity increases
Solution Approach 1:
The patent combines multiple information signals into a single pulse signal by superimposing second information (modulation signal) on the first pulse signal. This merging approach allows multiple pieces of information to be transmitted through one signal line instead of requiring separate signal lines for each information type, thereby reducing device complexity while maintaining transmission reliability
Solution Approach 2:
The output signal generation circuit is designed to generate a universal pulse signal that can carry multiple types of information simultaneously. The circuit can adaptively modulate the pulse signal with different information content, making a single signal line capable of performing multiple information transmission functions that would otherwise require separate dedicated lines
2Adaptability or versatility
If multiple separate output signals are generated for different applications, then each application receives appropriate information, but the number of output signals and circuit complexity increases
Solution Approach 1:
The patent merges multiple application-specific information into a single modulated pulse signal. The second pulse generation circuit superimposes second information (which contains application-specific data) on the first pulse signal, creating one output signal that serves multiple applications simultaneously, thereby reducing circuit complexity while maintaining adaptability
Solution Approach 2:
The circuit employs dynamic signal generation where the pulse width and modulation characteristics can be adjusted based on the input information. The circuit adaptively changes the pulse signal parameters to accommodate different application requirements, enabling a single dynamic circuit to replace multiple static circuits designed for specific applications
