Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If standard input power supply generation uses a one size fits all strategy, then device complexity is reduced, but power efficiency and performance deteriorate
Solution Approach 1:
The patent segments the power supply management by creating separate power supply units for different device types (e.g., compute devices, storage devices, network devices) within the data center. Each segment receives customized power profiles based on its specific power requirements, eliminating the one-size-fits-all approach while maintaining manageable complexity through modular organization.
Solution Approach 2:
The patent implements local quality by providing customized power supply characteristics to different device segments based on their specific needs. Each device type receives tailored power profiles with appropriate voltage, current, and timing characteristics optimized for its operational requirements, thereby improving overall power efficiency without requiring complete system redesign.
2Device complexity
If dynamic prediction of power requirements is not implemented, then device complexity is reduced, but productivity and resource utilization deteriorate
Solution Approach 1:
The patent implements preliminary action by using machine learning models to predict future power requirements of devices before workloads are scheduled. The system analyzes historical power consumption data and forecasts upcoming power needs, allowing administrators to proactively plan workload placement and power allocation, thereby improving productivity without adding complex real-time control mechanisms.
3Loss of energy
If conventional power supply strategies are used, then loss of energy is reduced (through simpler systems), but harmful factors increase (overheating and device failure)
Solution Approach 1:
The patent implements feedback mechanisms by continuously monitoring actual power consumption of devices and comparing it with predicted values. The machine learning models are trained on this feedback data to improve future predictions, creating a closed-loop system that adapts to actual device behavior patterns and improves accuracy over time without requiring complex real-time control infrastructure.

AI summary
Systems and methods are provided for compressing a time-series dataset from a monitored device into a compressed dataset representation. Using an unsupervised machine learning model, the system may group a contiguous set of datapoints of the time-series dataset and group, using a distance algorithm, the first cluster to a first motif. Many motifs can be generated to identify different data signatures in the time-series dataset. The plurality of motifs can be used to generate a data definition, motif sequence graph, directed graph, or other combinations of datapoints. These datapoints can be combined through a summation process with other datapoints generated by a second machine learning model. The output of the summation process can be used to forecast device usage of a monitored device in a data center.
