Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If complex arrangements of switches and controllers are used to manage power flow between charge storage medium and multiple buses, then power distribution capability is improved, but system complexity increases
Solution Approach 1:
The patent merges multiple switch control functions into a single electronic controller that manages both the first and second switches. This consolidation reduces the number of separate control mechanisms while maintaining the ability to distribute power across multiple buses, thereby improving power distribution capability without proportionally increasing system complexity.
Solution Approach 2:
The electronic controller serves multiple functions: it controls the first switch for connecting the charge storage medium to the first bus, controls the second switch for connecting to the second bus, and coordinates power flow management. This multi-functionality reduces the need for separate control mechanisms for each switch, addressing the contradiction between versatility and complexity.
2Device complexity
If the electrical charge storage medium is connected to a single power bus, then system simplicity is maintained, but flexibility and redundancy are limited
Solution Approach 1:
The patent implements a dynamic connection system where the charge storage medium can be selectively connected to different power buses based on operational needs. The electronic controller dynamically switches between connecting to the first bus via the first switch or the second bus via the second switch, providing flexibility and redundancy while maintaining relative system simplicity through centralized control.
Solution Approach 2:
The system segments the connection paths by providing separate switches for different buses, allowing independent control of connections to the first bus and second bus. This segmentation enables flexible power distribution across multiple buses while the electronic controller coordinates these segmented connections to maintain overall system simplicity.
3Productivity
If multiple switches are coordinated for efficient power distribution, then power distribution efficiency is improved, but coordination complexity increases
Solution Approach 1:
The patent combines the coordination functions for multiple switches into a single electronic controller that manages both switches centrally. This merging of coordination functions enables efficient power distribution across multiple buses while reducing the complexity of inter-switch coordination, as all coordination decisions are made by one controller rather than multiple independent control mechanisms.
4Measurement precision
If separate control mechanisms are used for each switch, then individual switch control precision is improved, but overall system reliability decreases
Solution Approach 1:
The patent merges the control mechanisms for multiple switches into a single electronic controller, reducing the number of potential failure points while maintaining precise control over each switch through centralized management. This approach improves overall system reliability by eliminating redundant control mechanisms while preserving the precision needed for individual switch operation through coordinated control strategies.
