Camera Module Filter Holder for Compact Integral Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional camera module packaging technologies face challenges in reducing the size of camera modules while ensuring the light filter's manufacturing accuracy and protecting it from damage, as they require larger light filters and have difficulties in controlling the assembly of the light filter's position and shape within the packaging structure.
Innovation Solution
The camera module incorporates a light filter holder that cooperates with an integral base, providing a supportive structure for the light filter, allowing it to be installed at a lower position closer to the photosensitive element, and features a supporting groove and engaging groove design to reduce the total height and assembly area, ensuring proper alignment and protection of the light filter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional packaging technology is used to embed electronic components, then the occupying space is reduced and dust is avoided, but the light filter size increases and manufacturing accuracy becomes harder to control
Solution Approach 1:
The patent divides the packaging structure into two separate components: an integral base for embedding electronic components and a separate light filter holder for mounting the light filter. This segmentation allows each component to be optimized independently, enabling small camera module size while maintaining light filter manufacturing accuracy through the dedicated holder structure with precise positioning features.
Solution Approach 2:
The light filter holder acts as an intermediary component between the integral base and the light filter. It provides a specialized mounting structure with engaging grooves and positioning features that ensure precise light filter placement and manufacturing accuracy, while allowing the integral base to focus on compact electronic component embedding.
2Device complexity
If the light filter is installed directly on the integral base, then the assembly is simplified, but the light filter is easy to be damaged and positioning accuracy is hard to control
Solution Approach 1:
The light filter holder serves as a protective intermediary between the integral base and the light filter. It provides a dedicated mounting structure with engaging grooves that securely hold the light filter, preventing damage during assembly and operation while maintaining positioning accuracy through specialized fixation features.
Solution Approach 2:
The light filter holder provides pre-established protection and positioning features before the light filter is installed. The engaging grooves and mounting structures are built into the holder in advance, ensuring the light filter is properly protected and positioned from the moment of installation, preventing damage and positioning errors.
3Area of stationary object
If a larger light filter is used to cover the packaging portion, then the filtering area is increased, but the manufacturing cost increases and manufacturing accuracy becomes harder to control
Solution Approach 1:
By separating the light filter mounting function from the electronic component embedding function, the patent allows the light filter to be sized precisely for its filtering needs rather than being oversized to cover the entire packaging portion. The light filter holder provides the necessary structural coverage, enabling a smaller, more cost-effective light filter with better manufacturing accuracy.
Solution Approach 2:
The light filter holder provides localized structural support and positioning features exactly where needed for light filter mounting, rather than requiring the light filter itself to provide overall structural coverage. This allows the light filter to be optimized for filtering performance with appropriate local features, reducing size and cost while maintaining accuracy.

AI summary
A camera module and an array camera module based on an integral packing process are disclosed. The camera module or each of the camera module units of the array camera module includes a circuit board, an integral base, a photosensitive element operatively connected to the circuit board, a lens, a light filter holder installed at the integral base and a light filter installed at the light filter holder. The light filter is not required to be directly installed to the integral base, so that the light filter is protected and the requiring area of the light filter is reduced.
