Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If macro-statistical methods are used for carbon emission measurement, then the measurement scope is large and comprehensive, but the measurement precision and detail of carbon emission in each link are insufficient
Solution Approach 1:
The patent divides the district heating system into multiple links including heat source, heat pipeline network, and heat user end, with further segmentation into supply water pipeline and return water pipeline. Carbon emission flow meters are installed at each segmented location to measure carbon emission flow rates independently, enabling precise identification of carbon emission details in each link while maintaining comprehensive system-wide measurement coverage.
2Area of stationary object
If macro-statistical methods are used for carbon emission measurement, then the measurement scope is large and comprehensive, but it is difficult to allocate carbon emission responsibilities between source and load sides
Solution Approach 1:
The system segments carbon emission measurement into distinct locations (heat source end, pipeline network, heat user end) with dedicated flow meters at each segment. This segmentation preserves information about where carbon emissions occur, enabling clear allocation of responsibilities between source (heat source), grid (pipeline network), and load (heat user end) sides.
Solution Approach 2:
The system provides real-time feedback of carbon emission flow rates at each link through a display device. This feedback mechanism enables transparent visualization of carbon emission distribution, allowing stakeholders to understand and allocate responsibilities based on actual measured data from each segment of the system.
3Measurement precision
If detailed carbon emission measurement in each link is implemented, then carbon emission responsibility allocation is clarified, but the device complexity increases
Solution Approach 1:
The patent introduces a carbon emission flow meter as an intermediary measurement device that directly measures carbon emission flow rate in the water flow. This intermediary device simplifies the overall measurement system by providing direct measurement rather than requiring complex calculation models, while still achieving detailed carbon emission tracking at each link.
4Measurement precision
If real-time carbon emission measurement is implemented, then accurate carbon emission tracking is achieved, but the device complexity and measurement cost increase
Solution Approach 1:
The carbon emission flow meter serves as an intermediary device that enables direct real-time measurement of carbon emission flow rates. By placing this intermediary measurement device in the water flow at key locations, the system achieves accurate real-time tracking without requiring complex distributed sensor networks or sophisticated calculation systems.
Solution Approach 2:
The system uses multiple identical carbon emission flow meters placed at different locations (heat source, pipeline, heat user end) to copy the measurement function across different system segments. This approach simplifies the overall system design by using repeated standard measurement units rather than developing complex unique measurement systems for each location.
