Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate antenna space is allocated in the device, then antenna placement is ensured, but device space is reduced and compactness is compromised
Solution Approach 1:
The patent combines the antenna with the connection member by forming the antenna on the flexible connection member itself. This merging eliminates the need for separate antenna spaces while ensuring reliable antenna placement within the limited device volume.
Solution Approach 2:
The connection member serves dual functions: it provides electrical connection between circuit boards and simultaneously functions as an antenna for wireless communication. This multi-functionality resolves the space conflict by eliminating redundant components.
2Adaptability or versatility
If the number of antennas is increased for advanced communication services, then communication capability is improved, but device complexity and space requirements increase
Solution Approach 1:
The patent segments the antenna function into multiple independent antenna elements that can be formed on the flexible connection member. This allows multiple antennas for advanced communication services while maintaining manageable device complexity through modular integration.
Solution Approach 2:
The patent utilizes the flexible connection member as a three-dimensional substrate to arrange multiple antenna elements in space, transitioning from planar to spatial configuration. This enables increased antenna count without proportionally increasing device footprint or complexity.
3Adaptability or versatility
If a flexible connection member is used to connect circuit boards, then device flexibility is improved, but electrical connection reliability may be compromised
Solution Approach 1:
The patent employs composite material structures in the connection member, combining flexible substrates with conductive materials and protective layers. This composite construction maintains flexibility while ensuring reliable electrical connections and antenna performance.
