Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable electronic devices with flexible displays face issues with static electricity induction, which can degrade antenna radiation performance due to conductive members hiding antenna radiation areas.
Innovation Solution
A conductive member with discontinuous patterns is designed to be periodically repeated between a protective frame and the edges of the flexible display, effectively inducing static electricity to ground while minimizing interference with antenna radiation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a continuous conductive member is used to induce static electricity to ground, then static electricity protection is improved, but antenna radiation performance deteriorates due to hiding the radiation area
Solution Approach 1:
The continuous conductive member is divided into multiple discrete conductive members arranged in a periodic pattern. This segmentation allows the conductive members to provide static electricity induction paths while creating gaps that prevent complete blocking of the antenna radiation area, thus resolving the contradiction between ESD protection and antenna performance
Solution Approach 2:
The conductive members are strategically positioned in specific locations rather than uniformly covering the entire area. This local placement optimizes the balance between providing sufficient static electricity induction capability and maintaining adequate antenna radiation space, addressing the contradiction by making the conductive structure location-dependent rather than uniform
2Reliability
If a conductive member is disposed close to the flexible display edge, then static electricity induction effectiveness is improved, but antenna radiation area is more significantly blocked
Solution Approach 1:
By segmenting the conductive member into discrete periodic elements, the patent enables closer positioning to the display edge while maintaining radiation area through the gaps between segments, effectively resolving the spatial conflict between induction effectiveness and radiation area preservation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution improves antenna radiation performance by ensuring static electricity is directed to ground without overlapping with the antenna's radiation area, enhancing wireless communication signals.
Implementation Method 1
Static electricity flowing from an outside may flow into the inside of the foldable electronic device through the edge of the flexible display. Such static electricity may be induced to a conductive plate electrically connected to a common ground of the electronic device through a conductive member disposed on the bending part.
