Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dedicated DC breaking units are created for each type (number of directions) in complicated networks, then the circuit breaker can handle multiple directional connections, but the device size and complexity increase
Solution Approach 1:
The patent applies universality by designing a single integrated circuit breaker that can handle multiple directional connections (2-directional, 3-directional, 4-directional, etc.) through a standardized breaking unit that can be configured in different slot arrangements. This eliminates the need for separate dedicated breaking units for each connection type, thereby reducing device size while maintaining adaptability to complicated networks.
Solution Approach 2:
The patent segments the circuit breaker into modular breaking units (each handling one directional connection) that can be independently configured and combined in a housing with multiple slots. This segmentation allows flexible arrangement of breaking units to match different network configurations without requiring complete redesign of the entire device, thus reducing overall device complexity and size.
2Use of energy by moving object
If capacitors are connected on output sides in breaking circuits, then energy can be managed across the network, but integration and downsizing become difficult
Solution Approach 1:
The patent segments the capacitor connections by providing separate capacitor terminals for each breaking unit output side, allowing independent energy management for each directional connection. This segmentation enables flexible wiring configurations where capacitors can be connected or disconnected independently for each branch, facilitating integration and downsizing while maintaining energy management capability across the entire network.
Solution Approach 2:
The patent enables dynamic configuration of capacitor connections through the modular slot system, where capacitor terminals can be selectively connected or disconnected based on the specific network requirements. This dynamic flexibility allows the same breaking unit to adapt to different energy management scenarios without requiring fixed, complex wiring arrangements.
