Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed reference humidity value is used for drying control, then the control method is simple, but the drying judgment becomes inaccurate under different ambient temperature and humidity conditions
Solution Approach 1:
The patent transforms the static fixed reference humidity value into a dynamic reference humidity value that automatically adjusts according to ambient temperature and humidity conditions. The control unit calculates the dynamic reference value in real-time based on environmental parameters, enabling the drying control system to adapt to varying conditions without increasing operational complexity.
Solution Approach 2:
The patent changes the reference humidity value parameter dynamically based on ambient temperature and humidity measurements. Instead of using a constant reference value, the system calculates a new reference value for each drying cycle according to the current environmental conditions, thereby improving judgment accuracy while maintaining simple control logic.
2Measurement precision
If the reference humidity value is adjusted dynamically based on ambient conditions, then the drying judgment accuracy improves, but the control system complexity increases
Solution Approach 1:
The control unit performs self-service by automatically calculating the dynamic reference humidity value based on ambient conditions detected by built-in sensors. The system uses its own detection elements to gather environmental data and computes the appropriate reference value without requiring external intervention or complex additional components, thus improving accuracy while limiting complexity growth.
Solution Approach 2:
The system implements feedback by continuously monitoring ambient temperature and humidity through detection elements, using this information to calculate and adjust the reference humidity value for each drying cycle. This closed-loop approach ensures accurate drying judgment while maintaining relatively simple control logic through automated feedback processing.
