Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the number of active servers is increased to handle higher workload, then user experience is improved, but power consumption increases
Solution Approach 1:
The system dynamically adjusts the number of active servers based on real-time workload monitoring. When workload exceeds thresholds, servers are automatically powered on; when workload decreases, servers are powered off. This dynamic adaptation resolves the contradiction by matching server capacity to actual demand, improving user experience during high load while reducing power consumption during low load periods.
Solution Approach 2:
The system implements continuous feedback loops that monitor workload metrics and automatically adjust server power states in response. The feedback mechanism detects workload changes and triggers appropriate power management actions, enabling the system to maintain acceptable user experience while minimizing power consumption through data-driven decisions.
2Use of energy by moving object
If the number of active servers is decreased to reduce power consumption, then power costs are minimized, but user experience deteriorates
Solution Approach 1:
The system maintains dynamic adaptability by continuously monitoring workload and adjusting server availability accordingly. During low-workload periods, servers are powered off to reduce consumption; during high-workload periods, servers are activated to maintain service quality. This dynamic behavior prevents user experience deterioration while achieving power savings.
Solution Approach 2:
The feedback mechanism ensures that power consumption reductions do not compromise user experience by continuously monitoring system performance metrics. When workload increases, the system receives feedback and automatically activates additional servers before user experience deteriorates, thus minimizing power costs while maintaining service quality.
3Use of energy by moving object
If servers are frequently powered on and off to optimize power usage, then power consumption is reduced, but system stability decreases
Solution Approach 1:
The system implements preliminary actions by establishing workload thresholds and delay mechanisms before making power state changes. Servers are not immediately powered on or off upon detecting workload changes; instead, the system waits for sustained threshold violations and incorporates delay periods. This preliminary action prevents frequent, unnecessary power transitions while still achieving power optimization, thus maintaining system stability.
Solution Approach 2:
The system provides cushioning against instability by incorporating delay mechanisms and threshold buffers before executing power state changes. These protective measures absorb normal workload fluctuations and prevent reactive power cycling, ensuring that power consumption is optimized only when genuinely necessary, thereby maintaining system stability.
4Use of energy by moving object
If manual server management is used to control power usage, then power consumption can be controlled, but operational complexity increases
Solution Approach 1:
The system enables self-service by automatically monitoring workload and managing server power states without requiring manual intervention. The automated system performs all necessary decisions about when to power servers on or off based on predefined thresholds and real-time conditions, significantly reducing operational complexity while maintaining effective power consumption control.
Solution Approach 2:
The automated feedback loop continuously monitors system state and adjusts power management decisions without human input. This eliminates the need for manual server management while achieving effective power consumption control, as the system autonomously responds to workload changes through programmed feedback mechanisms.

AI summary
A power control system for saving power by powering on enough application servers to satisfy the current load workload as well as any required reserve capacity based on administrative settings is disclosed. As the load increases, more servers are powered on. As the load decreases some servers are powered off. The power control system provides a reasonable end user experience at the least cost based on power consumption of the servers.
