Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If occupants manually set humidity level based on their comfort, then ease of operation is improved, but manufacturing precision and measurement precision of optimal humidity level deteriorate
Solution Approach 1:
The system automatically determines and maintains optimal humidity levels without requiring manual input from occupants. The processing device receives temperature data from sensors, determines optimal humidity levels using algorithms, and automatically controls HVAC or humidification systems, allowing the system to serve itself rather than relying on user expertise.
Solution Approach 2:
The system continuously monitors indoor and outdoor temperatures through sensors and uses this feedback to dynamically adjust humidity levels. The processing device receives real-time temperature data, processes it to determine current and optimal humidity levels, and adjusts system operation accordingly, creating a closed-loop control system that maintains precision without manual intervention.
2Object-affected harmful factors
If HVAC system operates to maintain user-defined humidity level, then comfort to occupants is improved, but use of energy deteriorates
Solution Approach 1:
The system dynamically changes the target humidity level parameter based on outdoor temperature conditions. Instead of maintaining a fixed user-defined humidity level, the processing device adjusts the optimal humidity setpoint according to real-time outdoor temperature data, allowing the system to maintain comfort while adapting to environmental conditions to reduce energy consumption.
Solution Approach 2:
The system transitions from static, user-defined humidity control to dynamic, algorithm-driven humidity management. The processing device continuously processes temperature data and adjusts humidity targets in real-time based on outdoor conditions, enabling the system to respond dynamically to changing environmental factors and optimize energy usage while maintaining occupant comfort.
3Device complexity
If system considers only indoor temperature for humidity control, then device complexity is reduced, but measurement precision of optimal humidity level deteriorates
Solution Approach 1:
The system adds the outdoor temperature dimension to the humidity control calculation. By incorporating outdoor temperature data from additional sensors into the processing device's algorithms, the system gains more comprehensive environmental context for determining optimal humidity levels, improving measurement precision without significantly increasing device complexity.
