Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Static electricity flowing into foldable electronic devices through the edges of flexible displays can degrade antenna radiation performance by hiding the antenna radiation area and inducing static electricity to a conductive plate connected to a common ground.
Innovation Solution
A conductive member is designed in discontinuous patterns to induce static electricity to ground, improving antenna performance by reducing overlap with the antenna radiation area.
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 antenna radiation area
Solution Approach 1:
The conductive member is divided into multiple discontinuous patterns instead of using a continuous conductive layer. This segmentation allows the conductive member to induce static electricity to ground while creating gaps that prevent complete blocking of the antenna radiation area, thus resolving the contradiction between static electricity protection and antenna radiation performance
Solution Approach 2:
The conductive member is strategically positioned and patterned to provide localized static electricity induction only where needed, rather than using a uniform continuous layer. This local quality approach allows static protection in specific areas while maintaining antenna radiation performance in other areas
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
The conductive member effectively directs static electricity to ground, enhancing antenna radiation performance by minimizing interference and maintaining signal integrity.
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
