Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If power is supplied through external and internal wiring to the operating module, then the operating module can perform its function, but voltage drops and noise are introduced causing malfunction and unwanted noise
Solution Approach 1:
The patent implements a feedback mechanism where the operating module monitors the power supplied to it through sensing circuits that detect voltage levels and noise characteristics. This monitoring feedback allows the system to identify power quality issues and adjust accordingly, resolving the contradiction between maintaining reliable operation and preventing voltage drops and noise interference.
2Measurement precision
If a measuring device is added to monitor power supplied to the operating module, then power quality can be detected, but device complexity increases
Solution Approach 1:
The patent merges the power monitoring function with the existing operating module by integrating sensing circuits and measurement capabilities directly into the module's internal structure. This consolidation allows power quality detection without adding separate external measuring devices, thus achieving measurement precision while minimizing increases in device complexity.
Solution Approach 2:
The operating module performs self-monitoring of its own power supply conditions through integrated sensing circuits. The module autonomously detects voltage drops and noise levels without requiring external measurement equipment, enabling the system to serve its own monitoring needs and reducing overall device complexity.
