Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single outer cover member is used to envelop the power generation element, then the device complexity is low, but the detection accuracy of breakage state is insufficient
Solution Approach 1:
The outer cover member is divided into a first outer cover body and a second outer cover body, creating separate enclosed spaces. This segmentation allows independent detection of breakage in each section, significantly improving detection accuracy while maintaining reasonable structural complexity through modular design
Solution Approach 2:
The patent introduces a spatial dimension by creating multiple enclosed spaces (first enclosed space and second enclosed space) within the outer cover structure. This dimensional approach enables multi-point detection capability, enhancing breakage detection accuracy without proportionally increasing overall complexity
2Measurement precision
If a double outer cover structure with multiple enclosed spaces is implemented, then the detection accuracy of breakage state increases, but the device complexity increases
Solution Approach 1:
The detection system is segmented into multiple independent detection units, each monitoring specific enclosed spaces. This segmentation allows the complex detection task to be divided into simpler sub-tasks, improving overall detection accuracy while managing system complexity through modular architecture
Solution Approach 2:
The second outer cover body is nested within the first outer cover body, creating a hierarchical structure with enclosed spaces at different levels. This nesting principle allows efficient use of space and enables multi-level detection capability without proportionally increasing overall device complexity
3Reliability
If detection units monitor multiple enclosed spaces, then the reliability of safety detection improves, but the use of energy increases
Solution Approach 1:
The detection function is segmented across multiple detection units, each responsible for specific enclosed spaces. This segmentation improves reliability through distributed detection capability while managing energy consumption by allowing individual units to operate independently at lower power levels
Solution Approach 2:
Gas-filled enclosed spaces serve as intermediaries that transmit information about breakage states to detection units. This intermediary mechanism enables indirect detection, improving reliability while reducing direct energy consumption compared to active sensing methods
