Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a centralized authority sets the rules for coordinating actions in an energy supply system, then coordination control is improved, but efficiency is reduced and transparency is reduced
Solution Approach 1:
The patent segments the centralized coordination function into multiple decentralized state estimators distributed across different system participants. Each estimator independently determines system states using local measurements and shared data, eliminating the need for a single central authority while maintaining coordination through consensus mechanisms.
Solution Approach 2:
The patent implements feedback mechanisms where state estimators continuously share their determinations and measurements with other participants. This allows the system to self-coordinate through iterative validation and consensus, improving both efficiency and transparency while maintaining operational control.
2Ease of operation
If a centralized authority sets the rules for coordinating actions in an energy supply system, then coordination control is improved, but transparency is reduced
Solution Approach 1:
The patent distributes the coordination function across multiple independent state estimators rather than concentrating it in a single central authority. This segmentation allows each participant to independently verify system states based on their own measurements and shared data, thereby improving transparency while maintaining coordination control.
Solution Approach 2:
The patent combines local measurements from multiple participants with shared system data to create a comprehensive view of system states. This merging of information sources enables transparent verification while maintaining coordinated control through consensus among participants.
3Duration of action of stationary object
If conventional systems are used for determining system state, then system operation is maintained, but the risk of supply threats and critical states such as local power outages increases
Solution Approach 1:
The patent performs preliminary determination of system states continuously using multiple independent state estimators before critical conditions can develop. By proactively identifying potential supply threats and critical states through decentralized validation, the system can take preventive actions to avoid power outages and maintain supply security.
Solution Approach 2:
The patent creates a cushioning effect against supply threats by implementing redundant state estimation and validation mechanisms. Multiple independent estimators provide backup verification, and the decentralized architecture prevents single-point failures, thereby cushioning the system against potential supply disruptions and critical events.
