Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing energy management systems struggle to effectively compare energy performance across equivalent operating statuses, making it difficult to focus on and analyze the relationship between operating status and energy performance in time-series variations.
Innovation Solution
An energy management system that includes an information collector and a display controller, which collates and displays energy consumption data and performance indicators across physical or logical boundaries and operating statuses using a three-dimensional space representation, allowing for hierarchical structuring and surface-based information display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If energy management systems display time-series energy consumption data using conventional methods, then the system can show energy performance over time, but it becomes difficult to compare energy performance at equivalent operating statuses
Solution Approach 1:
The patent introduces a dual-axis coordinate system where the horizontal axis represents time series and the vertical axis represents operating status categories. This dimensional transformation allows energy consumption data to be plotted and compared across equivalent operating statuses while maintaining temporal context, directly resolving the contradiction between information completeness and comparison capability
Solution Approach 2:
The patent segments energy consumption data by dividing it into multiple categories based on operating statuses (e.g., idle, running, shutdown). This segmentation enables selective comparison of energy performance within each operating status category while preserving the overall time-series structure, thus improving comparison capability without excessive complexity
2Loss of information
If the system displays detailed energy consumption data for multiple operating statuses, then comprehensive energy performance information is provided, but the ease of identifying equivalent operating status comparisons deteriorates
Solution Approach 1:
The patent employs color coding to differentiate various operating status categories in the graphical display. Each operating status is represented by a distinct color or shading pattern, enabling users to quickly identify and compare equivalent operating statuses across different time periods without having to analyze detailed numerical data, thus improving ease of operation while preserving comprehensive information
Solution Approach 2:
By adding the operating status dimension to the traditional time-series display, the patent creates a two-dimensional graphical interface where energy consumption can be visually compared across equivalent operating statuses. This dimensional enhancement makes it easy to identify patterns and anomalies while maintaining detailed energy performance information
