Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional antenna designs are used, then device appearance and compactness are maintained, but wireless communication performance deteriorates
Solution Approach 1:
The support structure is merged with the second antenna units by using conductive material for the support, allowing it to serve dual functions as both a structural element and an antenna component. This integration improves wireless communication performance without requiring additional space for separate antenna components.
Solution Approach 2:
The support is designed to perform multiple functions: it provides structural support for the antenna assembly and simultaneously acts as the second antenna units. This multi-functionality enables improved communication performance while maintaining device compactness, as the same component serves both mechanical and electromagnetic purposes.
2Volume of moving object
If antenna units are placed closer together, then device volume is reduced, but signal transmission efficiency deteriorates
Solution Approach 1:
An insulating layer is introduced as an intermediary between the first antenna units and the support (second antenna units). This mediator allows the antenna units to be positioned closely together for compactness while maintaining adequate electrical insulation and signal transmission efficiency, preventing unwanted electromagnetic interference between adjacent antenna elements.
3Reliability
If support structure is made larger, then antenna placement is optimized, but device compactness deteriorates
Solution Approach 1:
The support structure is merged with the second antenna units, eliminating the need for a separate, larger support structure. The conductive support itself becomes the antenna element, optimizing antenna placement while minimizing the area occupied by structural components.
Solution Approach 2:
The support performs dual functions as both a mechanical support structure and as the second antenna units. This multi-functionality allows for optimized antenna placement without requiring additional space, as the same component provides both structural and electromagnetic functions.
4Reliability
If insulating material is added between antenna units, then signal transmission is improved, but device compactness deteriorates
Solution Approach 1:
A thin insulating layer is used between the first antenna units and the support, providing necessary electrical insulation and improved signal transmission while occupying minimal space. This thin film approach maintains device compactness while achieving the required electrical isolation for optimal signal transmission.
