Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional heat-dissipation structures are used with multiple fans, then heat dissipation is adequate under normal conditions, but heat-dissipation efficiency decreases when fans stop working
Solution Approach 1:
The heat-dissipation structure is designed to be rotatable, allowing it to dynamically change its orientation and airflow passage configuration in response to different operating conditions, including fan failures. This enables the system to adapt its heat dissipation pattern rather than remaining static, resolving the contradiction between reliable heat dissipation and adaptability to fan failure.
Solution Approach 2:
The system changes the physical parameter of airflow passage orientation by rotating the heat-dissipation structure to different positions. This parameter change allows the system to optimize airflow paths based on which fans are operational, maintaining heat-dissipation efficiency across varying conditions.
2Reliability
If airflow amount is increased to improve heat dissipation, then heat-dissipation efficiency improves, but system complexity increases
Solution Approach 1:
Rather than using multiple complex control mechanisms for each fan, the invention employs a single rotatable heat-dissipation structure that can be positioned to optimize airflow. This dynamic reconfiguration approach improves heat dissipation without proportionally increasing system complexity.
3Productivity
If processing chips operate at full speed, then computing efficiency improves, but heat generation increases leading to overheating
Solution Approach 1:
The rotatable heat-dissipation structure is prepared in advance with multiple positional configurations that correspond to different thermal loads and fan operational states. When processing chips operate at full speed, the system can immediately switch to the appropriate configuration rather than reacting to overheating, preventing temperature issues before they occur.
Solution Approach 2:
The system incorporates sensors that detect temperature and fan operational status, providing feedback to the control device. This feedback mechanism allows the system to monitor chip temperature and airflow conditions, automatically adjusting the heat-dissipation structure's position to maintain optimal thermal conditions during high-speed operation.
