Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If refrigeration devices operate continuously to ensure normal operation of virtual machines, then reliability of service is improved, but energy consumption increases
Solution Approach 1:
The refrigeration system transitions from static continuous operation to dynamic operation that adapts to changing thermal loads. The control method dynamically adjusts refrigeration device operation based on real-time monitoring of virtual machine states and thermal environment, enabling the system to optimize between reliability and energy consumption under varying conditions
Solution Approach 2:
The system implements feedback control by monitoring thermal environment parameters and virtual machine states, then adjusting refrigeration device operation accordingly. The control method uses feedback from temperature sensors and virtual machine status to determine when refrigeration is needed, eliminating continuous operation and reducing energy waste while maintaining service reliability
2Ease of operation
If independent control systems are used for IT device layer and infrastructure layer, then ease of operation is improved, but energy efficiency deteriorates
Solution Approach 1:
The invention merges the control functions of the IT device layer and infrastructure layer into a unified control system. By combining these previously independent control systems, the patent enables coordinated management of virtual machines and refrigeration devices, allowing the system to optimize energy efficiency while maintaining operational simplicity through integrated control
3Use of energy by moving object
If virtual machines are powered off to reduce computational energy consumption, then energy saving is improved, but refrigeration energy waste increases
Solution Approach 1:
The patent introduces an intermediary control mechanism that bridges the gap between virtual machine power states and refrigeration device operation. This intermediary system monitors both virtual machine states and thermal conditions, then coordinates their interaction to ensure refrigeration devices are adjusted appropriately when virtual machines are powered off, preventing energy waste in both computational and refrigeration systems
