Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If antenna functions are integrated into the border structure, then terminal space utilization is improved, but structural complexity increases
Solution Approach 1:
The patent combines the antenna structure with the border structure of the terminal, making the border serve dual purposes as both structural support and antenna element. This merging of functions allows the antenna to be integrated into the existing border without requiring additional separate antenna components, thereby improving space utilization while managing structural complexity through functional consolidation
Solution Approach 2:
The border structure is designed to perform multiple functions: it provides structural support for the terminal while simultaneously serving as an antenna element for wireless communication. This multi-functionality allows the same structural component to fulfill both mechanical and electromagnetic roles, optimizing space usage and reducing the need for additional components
2Adaptability or versatility
If sound output holes are formed in the border antenna, then audio assembly integration is improved, but antenna performance may deteriorate
Solution Approach 1:
The border antenna is designed with different local characteristics: certain portions contain sound output holes to accommodate audio assembly integration, while other portions maintain continuous conductive structures to ensure antenna performance. This local differentiation allows different sections of the border to serve different functions - acoustic openings where needed and continuous conductive paths where antenna performance is critical
Solution Approach 2:
The border antenna structure is segmented into different functional zones: segments with sound output holes for audio integration and segments with continuous conductive material for antenna function. This segmentation allows the antenna to coexist with audio openings by dividing the border into specialized regions that optimize for their respective functions
3Adaptability or versatility
If multiple antenna types and frequency bands are supported, then communication capability is improved, but space requirements increase
Solution Approach 1:
The border structure is designed as a universal antenna platform that can support multiple antenna types and frequency bands through different configuration options. The same border structure can be adapted to accommodate various antenna designs (such as different feed point configurations, conductive patterns, and grounding arrangements) without requiring fundamentally different structural solutions, thereby supporting enhanced communication capability within the same physical space
