VSEngineering Contradiction Analysis

1Measurement precision

If the system monitors individual component loads and generates detailed load profiles, then prediction accuracy is improved, but device complexity increases

Engineering Contradiction:
Improveprediction accuracyVSAvoiddevice complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system segments the facility loads into multiple individual component loads, creating separate load profiles for each component. This segmentation allows the system to monitor and predict power consumption at a granular level, improving overall prediction accuracy while managing complexity through modular organization of monitoring data.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary actions by monitoring and storing load profile data for each component before generating predictions. Historical load profiles are collected and analyzed in advance, enabling the system to predict future power consumption patterns without requiring complex real-time calculations during prediction events.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If the system categorizes loads into critical and non-critical groups, then productivity is improved, but device complexity increases

Engineering Contradiction:
Improvepower management efficiencyVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system applies local quality by assigning different characteristics to different load groups. Critical loads are identified and separated from non-critical loads, allowing the system to apply different prediction and management strategies to each group. This differentiation improves power management efficiency by prioritizing essential loads while simplifying handling of non-essential loads.

Inventive Principle:
Principle #3Local quality
