Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an adapter board is used to connect between metal conductors and battery management system, then connection compatibility is improved, but device complexity increases
Solution Approach 1:
The patent merges the adapter board functionality directly into the flexible flat cable by integrating a base board with conductive wires and signal pads. This combination allows the FFC to directly connect to connectors with different pin distances without requiring a separate adapter board, thereby reducing device complexity while maintaining connection compatibility.
Solution Approach 2:
The base board is designed with multiple conductive wires and signal pads that can connect to connectors with different pin distances. This multi-functional design allows a single FFC to accommodate various connection configurations, eliminating the need for different adapter boards for different connector types.
2Adaptability or versatility
If an adapter board is used to accommodate different pin distances, then adaptability is improved, but ease of operation deteriorates
Solution Approach 1:
By combining the adapter board functionality into the base board, the patent eliminates the need for users to handle and install separate adapter boards. The integrated design allows for simpler installation and operation, as users only need to connect the FFC directly to the connector without additional components.
3Adaptability or versatility
If multiple conductive wires and signal pads are integrated into the base board, then connection flexibility is improved, but manufacturing complexity increases
Solution Approach 1:
The base board is designed with segmented conductive wires and signal pads that can be independently configured for different connection requirements. This segmentation allows for flexible connection designs while maintaining standardized manufacturing processes for each component.
Solution Approach 2:
The base board employs universal conductive wires and signal pads that can serve multiple connection configurations. This multi-functionality reduces the variety of unique components needed, thereby simplifying manufacturing while maintaining connection flexibility.
