Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a temperature sensor and heating device are integrated with a microprocessor for automatic temperature control, then the temperature management of milk is improved, but the device complexity increases
Solution Approach 1:
The system uses a microprocessor to automatically control the heating device based on temperature sensor feedback, enabling the milk container to self-regulate temperature without manual intervention. The microprocessor monitors temperature continuously and activates the heating device only when needed, creating a self-service temperature management system.
Solution Approach 2:
The temperature sensor provides continuous feedback to the microprocessor about the actual milk temperature, which then adjusts the heating device accordingly. This closed-loop feedback system ensures the milk maintains the desired temperature range automatically, resolving the contradiction between improved temperature control and increased device complexity.
2Reliability
If a timer and quantity transmitter are added to control pasteurization timing and heating duration, then the pasteurization effectiveness is improved, but the device complexity increases
Solution Approach 1:
The timer allows users to pre-set the pasteurization duration and timing before the actual heating process begins. The quantity transmitter pre-determines the appropriate heating duration based on milk volume. These preliminary settings ensure reliable pasteurization without requiring complex real-time adjustments during the heating process.
Solution Approach 2:
The patent replaces manual timing and quantity estimation with electronic timer and quantity transmitter components controlled by a microprocessor. This substitution of mechanical/manual controls with electronic systems improves pasteurization reliability while keeping the added complexity manageable through integration.
3Object-affected harmful factors
If a cooling coil with controllable valve is integrated for rapid cooling after pasteurization, then the hygiene quality is improved, but the device complexity increases
Solution Approach 1:
The cooling coil enables rapid cooling of pasteurized milk by forcing cold water through the coil, quickly bringing the milk temperature down to feeding temperature. This rapid cooling minimizes the time milk spends in the temperature range where germ formation occurs, effectively addressing hygiene concerns without requiring complex refrigeration systems.
Solution Approach 2:
The cooling coil system uses cold water as an intermediary medium to transfer heat away from the milk. Instead of directly refrigerating the milk, the system circulates cold water through the coil, which absorbs heat from the milk and carries it away, providing efficient cooling with simpler infrastructure.
4Measurement precision
If a level gauge is integrated to measure milk quantity and provide feedback to the microprocessor, then the feeding precision is improved, but the device complexity increases
Solution Approach 1:
The level gauge provides continuous feedback to the microprocessor about the milk quantity in the container. This information is used to automatically adjust heating duration, pasteurization timing, and feeding amounts. The feedback loop ensures precise measurement and control of milk quantity without requiring manual measurement, improving feeding precision while managing complexity through automated processing.
