Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If fixed circuit boards are used within the enclosure, then structural stability is improved, but reconfiguration capability deteriorates
Solution Approach 1:
The patent applies the dynamics principle by replacing fixed circuit boards with a flexible backplane that can dynamically adapt its configuration. The flexible backplane allows the enclosure to transition from a static to a dynamic structure, enabling reconfiguration of electronic devices while maintaining structural integrity through its flexible yet supportive design.
Solution Approach 2:
The patent applies segmentation by dividing the enclosure into modular components including the flexible backplane, drawer chest with multiple drawers, and interchangeable electronic devices. This segmentation allows independent replacement and reconfiguration of individual modules without affecting the entire system, resolving the contradiction between structural stability and reconfiguration capability.
2Reliability
If extensive wiring is used to connect filter modules, then connection reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The patent applies the extraction principle by removing the extensive wiring complexity from the system. The flexible backplane integrates connection functions directly into the board structure, extracting the need for separate extensive wiring harnesses. This maintains connection reliability through direct integrated connections while dramatically improving ease of operation by eliminating manual wiring tasks during reconfiguration.
Solution Approach 2:
The flexible backplane serves multiple functions simultaneously: it provides structural support, enables electrical connections, and facilitates reconfiguration. This multi-functionality eliminates the need for separate extensive wiring systems while maintaining connection reliability, as the backplane itself performs both structural and electrical connection roles.
3Manufacturing precision
If fixed electronic circuit boards are used, then manufacturing precision is improved, but adaptability deteriorates
Solution Approach 1:
The patent applies dynamics by transitioning from fixed, rigid circuit boards to a flexible backplane that can adapt its configuration. The flexible backplane maintains manufacturing precision through controlled flexibility, allowing it to be precisely manufactured while still enabling dynamic reconfiguration for device interchangeability.
Solution Approach 2:
The patent applies parameter changes by modifying the physical properties of the backplane from rigid to flexible. This parameter change enables the backplane to maintain manufacturing precision through controlled flexibility while simultaneously providing adaptability for different electronic device configurations, resolving the contradiction between precision and adaptability.
4Reliability
If discrete components and gas filter tubes are used, then filtering performance is improved, but device complexity increases
Solution Approach 1:
The patent applies merging by integrating the filtering components directly onto the flexible backplane structure. Instead of separate discrete components and gas filter tubes requiring extensive wiring, the filtering functionality is combined with the backplane itself, reducing wiring complexity while maintaining filtering performance through integrated design.
