Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in reducing antenna interference between the conductive housing and the camera module, while maintaining design aesthetics.
Innovation Solution
The proposed solution involves electrically connecting the camera bracket to the conductive housing used as an antenna, and providing a segmented portion adjacent to the camera bracket with a ground between them to prevent induced current scattering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the camera bracket is electrically connected to the conductive housing used as an antenna, then design aesthetics are improved, but antenna interference increases due to induced current scattering
Solution Approach 1:
The conductive housing is divided into segmented portions that are electrically isolated from each other. The camera bracket is connected to one segmented portion while other segmented portions serve as ground references, preventing induced current from scattering across the entire housing structure while maintaining the aesthetic benefit of electrical connection.
Solution Approach 2:
Different regions of the housing are assigned different electrical functions: one segmented portion is connected to the camera bracket as a signal reference, while other segmented portions are designated as ground. This local differentiation allows the camera bracket to be electrically connected for aesthetic purposes while confining current paths to specific local regions rather than allowing widespread interference.
2Object-affected harmful factors
If the camera module is spaced apart from the conductive portion used as antenna, then antenna interference is reduced, but design aesthetics deteriorate
Solution Approach 1:
The housing is segmented into electrically isolated portions, allowing the camera bracket to be positioned close to the conductive housing for aesthetic purposes while the segmentation prevents electrical interference. The camera bracket connects to one segmented portion while other portions serve as isolated ground references.
3Reliability
If a ground portion is added between the camera bracket and segmented portion, then antenna performance is improved by restricting resonance, but device complexity increases
Solution Approach 1:
The ground portion is merged with the segmented portions of the housing structure, utilizing the existing conductive housing as both the antenna element and the ground reference. This integration approach improves antenna performance by providing proper grounding to restrict resonance while avoiding additional separate ground structures that would increase device complexity.
