Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If environment additive value is calculated based on power losses in the power path, then measurement precision of power utilization is improved, but device complexity and loss of energy increase due to additional monitoring and compensation mechanisms
Solution Approach 1:
The patent extracts the power loss component from the environment additive value calculation by identifying alternative power that compensates for losses. The controller separates the actual power loss from the output power with environment additive value, allocating environment additive value only to the output power portion that successfully reaches the consumption facility, while treating power losses as separate alternative power from other sources.
Solution Approach 2:
The controller acts as an intermediary that manages the complex relationship between output power, power losses, and environment additive value allocation. It receives information about output power and consumption power, identifies the occupied output power portion, calculates alternative power corresponding to losses, and determines the appropriate environment additive value allocation without requiring direct measurement or compensation of power losses in the transmission path.
2Reliability
If environment additive value is calculated based on power losses, then reliability of power accounting is improved, but ease of operation deteriorates due to complex tracking requirements
Solution Approach 1:
The patent extracts the power loss accounting burden from the operation process by having the controller automatically identify alternative power corresponding to losses. The system separates reliable power accounting (tracking output power and consumption power) from loss compensation (automatically calculated by the controller based on identified occupied output power and alternative power relationships).
Solution Approach 2:
The controller performs self-service by automatically managing the complex power accounting and environment additive value allocation without requiring manual intervention. It receives power information from output and consumption facilities, autonomously identifies occupied output power, calculates alternative power for losses, and determines environment additive value allocation, thereby maintaining reliable accounting while simplifying operation.
3Productivity
If power losses are considered in environment additive value calculation, then productivity of power utilization tracking is improved, but loss of time increases due to additional calculation and verification steps
Solution Approach 1:
The patent extracts the time-consuming power loss measurement and verification steps from the environment additive value calculation process. The controller directly identifies alternative power corresponding to losses based on the relationship between output power and consumption power, without requiring separate measurement or verification of power losses in the transmission path, thereby maintaining productive tracking while reducing time loss.
Solution Approach 2:
The system performs preliminary identification of occupied output power and alternative power relationships before final environment additive value allocation. The controller is configured to identify these power components in advance based on received power information, enabling efficient subsequent calculation of environment additive value without requiring additional real-time measurement or verification steps during power transmission.
