Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If distributed energy sources and electromobility are integrated into the power distribution grid, then energy generation capacity and flexibility are improved, but system complexity and difficulty in monitoring and control increase
Solution Approach 1:
The patent combines geographical information system (GIS) data with electrical network data into a unified visual interface. This merging allows operators to view both the physical location and electrical status of network components simultaneously, reducing the complexity of monitoring distributed energy sources and electromobility infrastructure while maintaining high integration capacity.
Solution Approach 2:
The control system is designed to handle multiple types of data and multiple functions through a single integrated interface. It can display geographical locations, electrical parameters, alarm messages, and control commands simultaneously, making the system adaptable to various distributed energy sources and electromobility applications without requiring separate specialized systems.
2Measurement precision
If detailed network status information is provided to operating personnel, then monitoring accuracy is improved, but information overload and decision-making difficulty increase
Solution Approach 1:
The patent applies local quality by providing detailed electrical and geographical information specifically for the focused region of interest, while automatically aggregating and summarizing information for peripheral regions. This allows operators to examine detailed network status where needed without being overwhelmed by comprehensive data from the entire network, thus maintaining monitoring accuracy while preventing information overload.
Solution Approach 2:
The network view is segmented into a focused region displaying detailed information and peripheral regions displaying aggregated summaries. This segmentation allows operators to concentrate on specific areas of interest with high measurement precision while the automated aggregation of peripheral information prevents decision-making difficulty by presenting processed, digestible data.
3Loss of information
If separate representations are used for different network operation tasks, then task-specific information completeness is improved, but system complexity and operator cognitive load increase
Solution Approach 1:
The patent merges multiple task-specific representations (geographical views, electrical single-line diagrams, alarm lists, control commands) into a single integrated graphical user interface. This unified interface maintains the completeness of task-specific information by allowing operators to access all necessary data views simultaneously without switching between separate systems, thereby reducing system complexity and operator cognitive load.
Solution Approach 2:
The graphical user interface is designed as a universal platform that performs multiple functions: displaying geographical locations, showing electrical parameters, presenting alarm messages, and enabling control commands. This multi-functional interface eliminates the need for separate specialized systems for different network operation tasks, reducing overall system complexity while maintaining information completeness for each task.
