Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a cooling fan is installed in the electronic component space to cool electronic components, then the cooling capability is improved, but the detection speed of cooling fan failure is insufficient
Solution Approach 1:
A temperature measuring part is installed in advance in the cool air passage to continuously monitor the temperature of cooling air. This preliminary measurement setup enables immediate detection of cooling fan failure when temperature abnormalities occur, without requiring additional detection time after failure occurs.
Solution Approach 2:
The temperature measuring part provides continuous feedback on the temperature of cool air in the cooling passage. When the cooling fan fails, the temperature feedback immediately reflects this abnormality, enabling rapid detection and response to the failure condition.
2Reliability
If the cooling fan operates continuously to prevent overheating, then the reliability of electronic components is improved, but the complexity of the cooling system increases
Solution Approach 1:
The temperature measuring part continuously monitors the cool air passage temperature and automatically triggers cooking operation cessation when abnormal temperature is detected. This self-monitoring and self-protection mechanism prevents electronic component overheating without requiring complex external control systems.
Solution Approach 2:
The temperature measurement and protection mechanism is installed in advance in the cool air passage. When cooling fan failure occurs, the system automatically detects and responds by stopping cooking operations before electronic components are damaged, maintaining reliability without adding complex control logic.
3Measurement precision
If the temperature measuring part is installed in the cool air passage to enable rapid failure detection, then the detection precision is improved, but the device complexity increases
Solution Approach 1:
The temperature measuring function is extracted as a separate, dedicated component installed specifically in the cool air passage. This focused measurement approach provides precise detection of cooling fan failure without requiring a complex comprehensive monitoring system for the entire appliance.
Solution Approach 2:
The temperature measuring part is strategically positioned in the cool air passage where it can directly detect temperature abnormalities indicating cooling fan failure. This localized measurement provides high detection precision for the specific function of monitoring cooling air temperature without unnecessary system complexity.
