Camera Module Lens Holder Segmentation for Filter Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing camera module assembly process is cumbersome and costly due to the need to remove the lens holder from the circuit board for cleaning, which can damage components and increase manufacturing costs.
Innovation Solution
A camera module design with a lens holder featuring inner and outer threads for secure engagement of the lens barrel, allowing the filter to be inserted and removed through mounting holes without disassembling the lens holder from the circuit board, along with a method for detecting and addressing contaminants or filter cracks without removing the lens holder.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lens holder is removed from the circuit board for cleaning the filter or image sensor, then the cleaning access is improved, but the assembly complexity increases and the risk of component damage increases
Solution Approach 1:
The lens holder is segmented by providing separate mounting holes for the filter and image sensor, allowing independent access to each component. The filter mounting hole enables filter removal without affecting the image sensor or lens module, thus simplifying the cleaning process while maintaining assembly integrity.
Solution Approach 2:
The filter is extracted as a separate, independently removable component through the dedicated filter mounting hole. This allows the filter to be removed and cleaned without removing the entire lens holder from the circuit board, eliminating the need for complex disassembly while improving cleaning accessibility.
2Ease of operation
If the lens holder is removed from the circuit board for cleaning, then the cleaning capability is improved, but the manufacturing cost increases
Solution Approach 1:
The lens holder structure is segmented with a dedicated filter mounting hole separate from the image sensor mounting area. This segmentation allows the filter to be serviced independently, reducing manufacturing costs by eliminating the need for expensive complete assembly disassembly procedures and reducing the risk of component damage during cleaning.
3Ease of operation
If the lens holder is removed from the circuit board, then the filter cleaning access is improved, but the time consumption increases
Solution Approach 1:
The filter is extracted as an independently accessible component through the filter mounting hole, allowing it to be removed and cleaned without removing the entire lens holder from the circuit board. This extraction approach significantly reduces the time required for filter maintenance while maintaining adequate cleaning access.
4Ease of operation
If the lens holder is removed from the circuit board, then the cleaning accessibility is improved, but the risk of component damage increases
Solution Approach 1:
The lens holder is segmented with a dedicated filter mounting hole that provides independent access to the filter. This segmentation allows the filter to be removed and cleaned without disturbing the image sensor, lens module, or other sensitive components, thereby maintaining high cleaning accessibility while minimizing the risk of component damage.

AI summary
A camera module includes a lens module, a circuit board, an image sensor, a lens holder and a filter. The lens holder includes a hollow main body and a bottom base connected to the main body. The main body is connected to the lens module. The bottom base defines a receiving cavity. A sidewall of the bottom based defines at least one mounting hole close to the hollow main body and communicating with the receiving cavity. The filter is positioned on the bottom base and received in the receiving cavity. The at least one mounting hole is configured for allowing the filter to enter into the receiving cavity or be taken out of the receiving cavity. The circuit board is positioned on the bottom base. The image sensor is received in the receiving cavity and electrically connected to the circuit board.
