Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an absorption pad is disposed between electrodes to absorb fluid, then sensing sensitivity and reaction speed are improved, but device complexity increases
Solution Approach 1:
An absorption pad is disposed between the first electrode and the second electrode to absorb leaked fluid. The absorption pad acts as an intermediary that enhances the sensing mechanism by concentrating the fluid between electrodes, thereby improving sensing sensitivity and reaction speed while maintaining a relatively simple overall device structure.
2Adaptability or versatility
If a complex housing structure with detachable sub-detection units is used, then adaptability and ease of installation are improved, but manufacturing cost and device complexity increase
Solution Approach 1:
The housing is divided into a first sub-detection unit and a second sub-detection unit that are detachably coupled to each other. Each sub-detection unit has a leak detection printed circuit board, allowing the sensor to be assembled in different configurations and adapted to various pipe diameters and installation locations, thereby improving adaptability while keeping the manufacturing process straightforward.
3Manufacturing precision
If traditional manufacturing processes are used, then manufacturing precision is maintained, but manufacturing time and cost increase
Solution Approach 1:
The leak detection printed circuit board integrates multiple functions including conductive patterns for leak detection, adhesive layers for mounting, and electrical connection elements. This integration allows the circuit board to serve multiple purposes simultaneously, simplifying the manufacturing process and enabling mass production while maintaining manufacturing precision.
