Engineering Contradiction Analysis
1Measurement precision
If traditional heat dissipation strategies use physical I2C link to monitor temperature, then temperature monitoring is achieved, but heat dissipation control efficiency is insufficient and timely adjustment cannot be made
Solution Approach 1:
The patent replaces the traditional physical I2C link monitoring mechanism with a virtual monitoring approach. The server controller obtains network interface card device information through virtual monitoring methods, eliminating the need for direct physical temperature sensing links while achieving real-time temperature monitoring and heat dissipation control, thereby improving control efficiency.
Solution Approach 2:
The patent introduces a virtual monitoring mechanism as an intermediary between the server controller and network interface card devices. This virtual monitoring layer enables the controller to obtain device information without direct physical connections, facilitating more efficient and flexible heat dissipation control while maintaining accurate temperature monitoring.
2Duration of action of stationary object
If heat dissipation strategy is not adjusted timely, then server operation continues, but high temperature causes components to crash or shut down
Solution Approach 1:
The patent implements a feedback mechanism where the server controller continuously monitors network interface card device temperature information and dynamically adjusts heat dissipation strategies based on real-time temperature changes. This closed-loop feedback system ensures timely adjustment of heat dissipation parameters, preventing temperature-induced crashes or shutdowns while maintaining continuous server operation.
Solution Approach 2:
The patent employs dynamic heat dissipation adjustment strategies where the server controller modifies heat dissipation parameters in real-time based on monitored temperature conditions. This dynamic adjustment capability allows the system to adapt to changing thermal conditions, ensuring both continuous operation and component reliability by preventing overheating before it causes crashes.
3Measurement precision
If physical I2C link is used for temperature monitoring, then direct temperature access is achieved, but device complexity and control flexibility are reduced
Solution Approach 1:
The patent replaces the physical I2C link monitoring system with a virtual monitoring architecture. The server controller uses virtual monitoring mechanisms to access network interface card device temperature information, eliminating complex physical sensing circuits and I2C communication hardware while maintaining accurate temperature measurement capabilities and reducing overall system complexity.
Solution Approach 2:
The patent implements a universal virtual monitoring mechanism that can access temperature information from multiple network interface card devices through a single controller interface. This multi-functional approach eliminates the need for separate physical monitoring circuits for each device, reducing system complexity while maintaining comprehensive temperature monitoring capability.
