Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed operation time is used for the heating air duct, then the device complexity is low, but the drying reliability is poor leading to under-drying and over-drying
Solution Approach 1:
The patent changes the drying parameter from a fixed time value to a dynamic value based on temperature monitoring. The control unit adjusts the drying time parameter according to the actual intracavity temperature, transforming the drying process from time-based to temperature-based control, thereby improving drying reliability without requiring complex sensor systems
Solution Approach 2:
The system uses the existing temperature detection capability of the sterilization container to automatically adjust drying time. The control unit processes the temperature data and determines the extended drying time autonomously, making the system self-regulating without additional external sensors or complex control mechanisms
2Reliability
If the heating air duct operates for extended time to ensure complete drying, then drying reliability improves, but energy consumption increases
Solution Approach 1:
The patent implements a feedback mechanism where the control unit continuously monitors intracavity temperature during drying and adjusts the heating air duct operation accordingly. When the temperature reaches the predetermined threshold, the control unit stops the heating air duct, preventing both under-drying and over-drying, thereby optimizing energy consumption while ensuring complete drying
Solution Approach 2:
The drying process transitions from a static fixed-time operation to a dynamic temperature-responsive operation. The heating air duct operates dynamically based on real-time temperature conditions, extending or reducing operation time as needed to achieve complete drying without energy waste
3Measurement precision
If multiple sensors are installed to monitor drying factors, then drying precision improves, but the cost increases significantly
Solution Approach 1:
The patent makes the existing temperature detection device serve multiple functions: it monitors both the sterilization process temperature and the drying process temperature. The control unit processes temperature data for both sterilization and drying control, eliminating the need for separate sensors and reducing system complexity while maintaining monitoring precision
Solution Approach 2:
The system uses its existing temperature detection and control capabilities to handle drying monitoring autonomously. The control unit determines drying completion based on temperature thresholds without requiring additional external sensing systems, making the system self-sufficient and cost-effective

AI summary
An intelligent drying method and an ultraviolet sterilization container are applied to an ultraviolet sterilization container for drying a sterilized article, the method comprising: that the sterilization container sequentially executes the following steps after receiving a drying instruction: releasing hot air to an article storage cavity; when an initial drying time is reached, collecting the intracavity temperature of the article storage cavity; automatically obtaining an extended drying time corresponding to the intracavity temperature of the article storage cavity; and continuously releasing hot air to the article storage cavity until the extended drying time is reached. The ultraviolet sterilization container includes: an article storage cavity, a heating air duct, a microprocessor, and a memory storing a computer readable program executable by the microprocessor. When the computer readable program is executed by the microprocessor, the sterilization container performs the above steps.
