Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If energy intensity is determined only at factory, building, or country level using related art methods, then overall energy consumption can be measured, but energy intensity for each specific product cannot be determined and energy-saving elements cannot be analyzed
Solution Approach 1:
The patent segments energy consumption data by product type, process line, and equipment to calculate energy intensity at multiple granularities. Instead of measuring only overall factory energy intensity, the system divides energy consumption into product-specific portions using production quantities and energy consumption records, enabling precise measurement of energy intensity for each product while maintaining the ability to analyze at aggregate levels.
2Loss of information
If detailed product-level energy intensity analysis is implemented, then energy-saving opportunities can be identified, but data collection and processing complexity increases
Solution Approach 1:
The patent creates a universal data structure and calculation framework that handles energy intensity analysis at multiple levels simultaneously. The same system infrastructure processes data for individual products, process lines, and aggregate totals using consistent methods, reducing the complexity increase that would otherwise result from implementing detailed product-level analysis.
3Ease of manufacture
If energy consumption monitoring is performed without product-specific analysis, then overall consumption patterns are visible, but targeted energy-saving measures cannot be implemented
Solution Approach 1:
The patent segments energy consumption data by product type, process line, and equipment to calculate energy intensity at multiple granularities. Instead of measuring only overall factory energy intensity, the system divides energy consumption into product-specific portions using production quantities and energy consumption records, enabling precise measurement of energy intensity for each product while maintaining the ability to analyze at aggregate levels.

AI summary
Provided is a method and a system for analyzing stability of factory energy consumption based on energy intensity per product. The method includes extracting a profile including a production history of a product and process operation information of a process line or process equipment used to produce the product, determining energy intensity per product, which is a ratio of an amount of energy consumed to produce the product for production of the product, based on the profile, and identifying consumption stability of energy consumed to produce the product based on the energy intensity per product.
