Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If front-end voltage input channels are shared by waveform capture and revenue measurement circuits, then device complexity is reduced, but measurement precision deteriorates due to crosstalk between circuits
Solution Approach 1:
The patent divides the voltage input channels into separate dedicated circuits: one set for waveform capture and another set for revenue measurement. This segmentation eliminates crosstalk between the two functions, allowing high-precision transient measurement in the waveform capture circuit while maintaining accurate revenue measurement in the separate circuit, thus resolving the contradiction between device complexity and measurement precision.
2Ease of manufacture
If shared circuits are used for multiple functions, then ease of manufacture is improved, but reliability deteriorates due to interference between measurement functions
Solution Approach 1:
The patent implements separate dedicated circuits for waveform capture and revenue measurement functions. This segmentation prevents interference between the two measurement functions, ensuring that transient detection and revenue measurement both operate reliably without mutual interference, thus resolving the contradiction between ease of manufacture and reliability.
3Productivity
If processing resources are shared between waveform capture and revenue measurement, then productivity is improved, but measurement precision deteriorates due to processing conflicts
Solution Approach 1:
The patent assigns dedicated processing resources to each function: waveform capture has its own processing path for transient detection, while revenue measurement has its own separate processing path. This segmentation eliminates processing conflicts and resource contention, allowing both functions to operate with high precision simultaneously, thus resolving the contradiction between productivity and measurement precision.
