Solution Overview
Problem
Existing wireless mobile terminals face challenges in enhancing their communication performance while maintaining a compact and aesthetically pleasing design.
Innovation Solution
The proposed antenna device includes a frame, a support made of conductive material, and an antenna assembly comprising a first and second antenna module. The support is insulated from the first antenna module and reused as part of the second antenna units, optimizing space and improving antenna function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the antenna device includes separate support structure and antenna units, then the antenna function is improved, but the space occupied by the device increases
Solution Approach 1:
The support structure is merged with the second antenna units by making the support conductive, allowing it to serve dual purposes as both a structural support and an antenna element, thereby reducing the space occupied by separate antenna components
Solution Approach 2:
The conductive support structure performs multiple functions simultaneously: it provides mechanical support for the first antenna module, acts as a second antenna unit for wireless communication, and eliminates the need for separate support and antenna components
2Volume of moving object
If the support is made of conductive material and reused as antenna units, then the space occupied is reduced, but the manufacturing complexity increases
Solution Approach 1:
The support structure and second antenna units are merged into a single conductive component, reducing the total number of parts and simplifying the assembly process despite the requirement for conductive material
3Reliability
If the first antenna module and support are insulated from each other, then the antenna performance is improved, but the device complexity increases
Solution Approach 1:
Insulation is applied locally only where the first antenna module contacts the support structure, rather than requiring complete insulation of the entire support, thereby minimizing the increase in device complexity while maintaining antenna performance
