Camera Module Shielding Sheet for Connector Noise
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic apparatuses, such as laptop PCs, the miniaturization and thinning of the chassis create a challenge in effectively shielding the camera module's connector from static electricity and noise, due to limited space and the need to cover adjacent components.
Innovation Solution
The electronic apparatus employs a sheet-shaped member with a pore, installed to cover the area from the connector unit to adjacent components, striding over gaps and level differences, ensuring comprehensive shielding while accommodating the miniaturized design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the chassis is miniaturized and thinned to reduce size, then the portability and compactness are improved, but the space for installation of the camera module is reduced, making it difficult to effectively shield the connector from static electricity and noise
Solution Approach 1:
The shielding sheet is extended in the thickness direction (Z direction) to form an overhanging portion that covers the connector from above. This vertical extension allows the shielding to effectively cover the connector without requiring additional horizontal space, thus resolving the contradiction between miniaturized chassis size and effective shielding coverage.
Solution Approach 2:
A thin sheet-shaped member (aluminum foil or conductive adhesive tape) is used as the shielding material. This thin film can be conformally applied to cover both the connector and adjacent components, providing effective shielding while occupying minimal space within the miniaturized camera module structure.
2Area of stationary object
If components are densely implemented on the substrate to save space, then the space utilization is improved, but gaps are created between the shielding member and the connector when attempting to cover the connector, compromising the shielding effectiveness
Solution Approach 1:
The shielding sheet is extended in the thickness direction (Z direction) to form an overhanging portion that reaches down to cover the connector. This vertical extension allows the shielding to effectively cover the connector without requiring additional horizontal space, thus resolving the contradiction between miniaturized chassis size and effective shielding coverage.
Solution Approach 2:
The shielding sheet is divided into multiple functional portions: a first portion covering adjacent components, a second portion covering the connector, and an overhanging portion extending between them. This segmentation allows each portion to be optimally positioned to eliminate gaps while maintaining overall shielding continuity.
3Adaptability or versatility
If a level difference is formed between the connector unit and adjacent components, then the component layout flexibility is improved, but gaps are created that prevent effective shielding coverage
Solution Approach 1:
The shielding sheet is extended in the thickness direction (Z direction) to form an overhanging portion that bridges the level difference between the connector and adjacent components. This vertical extension allows the shielding to continuously cover both components at different heights, resolving the contradiction between layout flexibility and shielding coverage.

Function Achieved in This Case
This solution effectively secures the shielding property of the camera module by preventing gaps between the shielding member and the connector, thus enhancing protection against static electricity and noise, even in densely packed camera modules.

AI summary
An electronic apparatus includes: a camera module which is loaded thereon. The camera module includes: a substrate; a connector unit which is implemented on the substrate; a component which is implemented on the substrate, is adjacent to the connector unit, leaving a gap between the component and the connector unit and that a level difference is formed between the surface thereof and the surface of the connector unit and is equipped with a sheet-shaped member for shielding electromagnetic waves which is so installed as to cover an area which ranges from the surface of the connector unit to the surface of the component, striding over the gap. The sheet-shaped member has a pore on a position where the sheet-shaped member overlaps with the gap vertically.
