Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If wireless detectors without marking information are used, then device complexity is reduced and ease of manufacture is improved, but detector identification capability deteriorates and operation reliability worsens
Solution Approach 1:
The detector system is segmented into functional components: the wireless detector unit without integrated marking, and the separate marking module with magnetic blocks. This segmentation allows the detector to remain simple and wireless while the identification function is provided by an external module, resolving the contradiction between manufacturing simplicity and identification reliability.
Solution Approach 2:
The magnetic blocks in the marking module serve as an intermediary that enables identification of wireless detectors. Since wireless detectors cannot provide active communication, the passive magnetic marking provides a intermediary mechanism for the identification module to detect and distinguish detector positions without requiring complex wireless communication infrastructure.
2Quantity of substance
If multiple detectors are deployed, then measurement capability and imaging coverage are improved, but operation complexity increases and identification difficulty worsens
Solution Approach 1:
Each detector position is assigned a unique local quality through the marking module with specific magnetic block configurations. The number, position, or arrangement of magnetic blocks creates distinct local characteristics for each detector, enabling the system to manage multiple detectors without increasing operational complexity since each can be individually identified by its unique magnetic signature.
3Device complexity
If visual identification method is used for multiple detectors, then no additional hardware is needed, but operation time increases and error rate worsens
Solution Approach 1:
The manual visual identification process is replaced by an automated magnetic sensing system. The identification module with magnetic sensors automatically detects the magnetic blocks in the marking modules, replacing the mechanical/visual process with a magnetic field-based automated detection system that reduces time and eliminates human error.
