Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a data center operates exclusively on renewable energy, then environmental sustainability is improved, but power supply stability deteriorates
Solution Approach 1:
The system performs preliminary actions by predicting future power generation amounts from renewable sources and storing this information in advance. The load distribution controller uses these predictions to proactively adjust job assignments between data centers before power shortages occur, ensuring continuous operation without interruption.
Solution Approach 2:
The patent introduces a load distribution controller as an intermediary that manages power allocation between multiple data centers. This controller receives power generation predictions, determines optimal load distributions, and coordinates job migrations, acting as a mediator that balances renewable energy variability with stable power supply across the system.
2Reliability
If solar panels and storage batteries are increased to ensure constant power supply, then power supply stability is improved, but installation costs increase
Solution Approach 1:
The system segments the power supply function across multiple data centers rather than relying on a single large-scale renewable energy installation. Each data center can operate with smaller, more manageable solar panels and storage batteries, while the load distribution controller coordinates between them to ensure overall system stability.
Solution Approach 2:
The patent merges multiple data centers into a coordinated system where excess power from one center can support another. By combining the power resources of multiple centers with moderate solar panel and battery installations, the system achieves greater overall reliability than any single center could provide alone.
3Reliability
If load distribution is implemented between data centers, then power supply stability is improved, but system complexity increases
Solution Approach 1:
The load distribution controller operates autonomously by automatically acquiring power generation predictions, calculating optimal load distributions, and executing job migrations without manual intervention. The system serves itself by monitoring its own power status and making real-time adjustments to maintain stability.
Solution Approach 2:
The system dynamically changes operational parameters such as job assignment locations and power distribution ratios based on real-time power generation predictions. The load distribution controller adjusts these parameters automatically in response to changing renewable energy availability, maintaining stability through adaptive parameter optimization.
