Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In terminal devices, the challenge of feeding and grounding an antenna in a small space is exacerbated by the large space occupied by electronic components, particularly the need for separate welding regions and spacing distances for feeding and grounding conductive spring plates, which complicates the use of antennas in compact designs.
Innovation Solution
The integration of a conductive spring plate with both feeding and grounding portions on a single plate, reducing the need for separate welding regions and spacing, and utilizing a circuit board assembly for flexible routing to connect distant components, thereby optimizing space utilization and connection stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate feeding conductive spring plate and grounding conductive spring plate are used, then electrical connection is achieved, but space occupation increases
Solution Approach 1:
The patent combines the feeding conductive spring plate and grounding conductive spring plate into a single integrated conductive spring plate structure. This merging eliminates the need for separate welding regions and reduces the total space required for both feeding and grounding connections, directly resolving the contradiction between achieving reliable electrical connection and minimizing space occupation.
Solution Approach 2:
The integrated conductive spring plate serves multiple functions simultaneously - it provides both feeding and grounding connections to the antenna. This multi-functional design eliminates the need for separate dedicated feeding and grounding plates, reducing space occupation while maintaining all necessary electrical connections.
2Reliability
If separate feeding conductive spring plate and grounding conductive spring plate are used, then electrical connection is established, but device complexity increases
Solution Approach 1:
By merging the feeding and grounding conductive spring plates into a single integrated structure, the patent reduces the number of separate components and welding operations required. This simplification directly addresses the contradiction by maintaining reliable electrical connection while reducing structural complexity.
3Reliability
If spacing distance is reserved between feeding and grounding plates, then contact reliability is ensured, but space occupation increases
Solution Approach 1:
The integrated conductive spring plate design eliminates the need for spacing between separate feeding and grounding plates. The single continuous structure ensures reliable contact while occupying minimal space, directly resolving the contradiction between contact reliability and space occupation.
