Camera Shield for Magnetic Crosstalk Reduction in Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing integration of components within mobile terminals leads to a small space where the camera module and handset assembly are closely arranged, resulting in magnetic crosstalk that affects their performance.
Innovation Solution
A shield is positioned between the camera module and the handset assembly to reduce magnetic field interference, using materials like stainless steel or wave-absorbing materials to minimize interference while optimizing space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the camera module and handset assembly are arranged close together to save space, then the space utilization is improved, but magnetic crosstalk between the two components increases
Solution Approach 1:
A shield is introduced as an intermediary component positioned between the camera module and the handset assembly. This shield acts as a mediator that blocks magnetic field lines, preventing direct magnetic coupling between the two components while allowing them to maintain close proximity for space efficiency.
Solution Approach 2:
The internal space of the terminal is segmented into distinct magnetic zones by introducing the shield. This divides the continuous space into separate regions with different magnetic field characteristics, isolating the camera module from the magnetic interference of the handset assembly.
2Object-affected harmful factors
If a shield is added between the camera module and handset assembly to reduce magnetic interference, then magnetic crosstalk is reduced, but device complexity increases
Solution Approach 1:
The shield is merged with the existing bracket structure that holds the camera module. By integrating the shielding function into the supporting bracket, the design eliminates the need for a separate standalone shield component, thereby reducing assembly complexity while maintaining magnetic interference protection.
