Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In foldable electronic devices, static electricity flowing from the outside can induce degradation in antenna radiation performance due to conductive members hiding the antenna radiation area and grounding through a conductive plate, leading to reduced antenna efficiency.
Innovation Solution
A conductive member is designed with discontinuous patterns periodically repeated to induce static electricity to ground, improving antenna performance by preventing interference with the antenna radiation area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a continuous conductive member is used to ground static electricity, then static electricity discharge capability is improved, but antenna radiation performance deteriorates due to blocking the radiation area
Solution Approach 1:
The continuous conductive member is divided into multiple discrete conductive members arranged in a specific pattern. This segmentation allows the conductive members to ground static electricity while creating gaps that prevent complete blocking of the antenna radiation area, thus resolving the contradiction between static electricity discharge capability and antenna radiation performance
Solution Approach 2:
The conductive members are strategically positioned in specific locations rather than uniformly distributed. This local quality approach ensures that static electricity discharge functionality is maintained in critical areas while leaving other areas open for effective antenna radiation, balancing both requirements
2Object-affected harmful factors
If a conductive member is placed near the antenna to discharge static electricity, then electrostatic protection is improved, but antenna efficiency deteriorates due to interference with the radiation area
Solution Approach 1:
By segmenting the conductive member into multiple smaller discrete members, the patent reduces the overall conductive area that could interfere with antenna radiation while maintaining sufficient discharge capability. The gaps between segmented members minimize interference with the radiation area
Solution Approach 2:
The conductive members act as intermediary elements that provide a controlled path for static electricity discharge while being positioned and sized to minimize their interference with antenna operation. They mediate between the need for electrostatic protection and the need for efficient antenna radiation
