Conductive Display Cowling Segmentation for Mobile Phone Grounding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern handheld electronic devices, such as smartphones, face challenges in efficiently integrating conductive components with the display assembly while maintaining a compact design and ensuring effective grounding.
Innovation Solution
The integration of a front cover assembly with conductive display cowlings positioned outside the outer periphery of the battery, coupled with a mounting frame that conductsively couples these components to a system ground, allows for efficient grounding and structural retention without overlapping the battery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conductive components are integrated with the display assembly, then grounding effectiveness is improved, but the risk of overlapping with the battery increases
Solution Approach 1:
The conductive display cowling is divided into multiple separate conductive regions (first conductive display cowling and second conductive display cowling) positioned at different locations below the display element. This segmentation allows each region to be independently positioned to avoid overlapping with the battery while collectively providing comprehensive grounding coverage for the front cover assembly.
2Length of stationary object
If the device thickness is reduced for compactness, then the overall device size is improved, but the clearance between battery and display assembly may be compromised
Solution Approach 1:
The conductive display cowlings extend in the horizontal dimension (lateral spacing) rather than increasing vertical thickness to provide the required clearance. By spacing the first and second conductive display cowlings apart horizontally and positioning them below the display element, the design maintains adequate clearance between the battery and display assembly while controlling overall device thickness.
3Reliability
If the first and second conductive display cowlings are spaced apart to avoid battery overlap, then grounding coverage is improved, but the structural complexity increases
Solution Approach 1:
The mounting frame serves multiple functions simultaneously: it provides structural support for the display assembly, acts as a conductive path to ground both the first and second conductive display cowlings, and maintains the spatial relationship between components. This multi-functionality reduces the need for additional grounding structures and simplifies the overall assembly.
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 configuration enables effective grounding of the front cover assembly, reduces the overall thickness of the device, and maintains a target clearance between the battery and the display assembly, enhancing the device's compactness and functionality.
Implementation Method 1
The mounting frame may be conductively coupled to the first conductive display cowling and the second conductive display cowling. The mounting frame, the first conductive display cowling, and the second conductive display cowling may be conductively coupled to a system ground of the mobile phone.

AI summary
A mobile phone may include a housing structure and a front cover assembly coupled to the housing structure and positioned over the battery. The front cover assembly may include a transparent cover defining at least a portion of a front exterior surface of the mobile phone and a display assembly coupled to the transparent cover and including a display element configured to produce graphical outputs visible through the transparent cover, a first conductive display cowling below a first region of the display element, and a second conductive display cowling below a second region of the display element and spaced apart from the first conductive display cowling, thereby forming a gap between the first conductive display cowling and the second conductive display cowling. The mobile phone may further include a battery positioned below the gap.
