Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If only object temperature and humidity sensors are used, then the device complexity is reduced, but the ability to detect the cause of water generation is insufficient
Solution Approach 1:
The detection system is segmented into two independent sensor units: object temperature and humidity sensors for monitoring the object surface, and environment temperature and humidity sensors for monitoring the surrounding air. This segmentation allows each sensor to capture specific information needed for comprehensive water generation cause analysis without requiring a single complex sensor system.
Solution Approach 2:
The control unit acts as an intermediary that receives data from both object and environment sensors, processes the information by comparing temperature and humidity differences, and determines the cause of water generation. This intermediary processing layer integrates information from multiple sources to resolve the contradiction between simple sensor deployment and comprehensive cause detection.
2Measurement precision
If temperature and humidity changes over time are analyzed, then the precision of water generation detection is improved, but the loss of time for data collection increases
Solution Approach 1:
The system continuously collects and stores temperature and humidity data from both object and environment sensors before water generation occurs. By maintaining a historical record of environmental conditions, the system can rapidly compare pre-event and post-event data when water generation is detected, eliminating the need for extended real-time observation periods while preserving detection precision.
Solution Approach 2:
The control unit continuously monitors temperature and humidity data and provides feedback when changes indicate water generation. This feedback mechanism allows the system to transition from continuous data collection to targeted analysis only when necessary, reducing overall time loss while maintaining high detection precision through immediate response to critical changes.
