Camera Module Dust-Blocking Member With Adhesive Groove Trap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dust particles can fall on the filter or photosensitive chip during the assembly of a camera module, degrading its imaging quality.
Innovation Solution
A dust collecting and blocking member is integrated into the camera module, comprising a frame body with an adhesive and recessed grooves, which traps and adheres dust particles during assembly, ensuring the optical components remain dust-free.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a camera module is assembled without additional protective components, then the assembly process is simple and quick, but dust particles fall on the filter or photosensitive chip, degrading imaging quality
Solution Approach 1:
The dust collecting and blocking member is pre-installed on the filter before the photosensitive chip is mounted. This preliminary protective action ensures that dust particles are trapped during the subsequent assembly operations, preventing contamination of the optical components without requiring complex protective measures during assembly.
Solution Approach 2:
The dust collecting and blocking member acts as an intermediary component between the assembly environment and the optical components. It serves as a protective barrier that intercepts dust particles, allowing the assembly process to proceed while maintaining cleanliness of the filter and photosensitive chip surfaces.
2Reliability
If a dust collecting and blocking member is added during assembly, then dust particles are trapped and optical components remain clean, but the assembly process becomes more complex
Solution Approach 1:
The dust collecting and blocking member is prepared and positioned in advance on the filter assembly. This preliminary preparation simplifies the overall assembly process by eliminating the need for complex dust prevention measures during assembly operations, as the protective component is already in place.
Solution Approach 2:
The dust collecting and blocking member is designed to be self-contained with integrating dust collection and blocking functions. The adhesive layer and groove structure are built into the component itself, allowing it to autonomously trap dust particles without requiring additional external protective systems or complex assembly procedures.

AI summary
A dust collecting and blocking member with an aperture for a camera module, includes a frame body and an adhesive connected to the frame body. The frame body includes a first surface and a second surface opposites to the first surface, the aperture penetrates the first surface and the second surface, the first surface is recessed inwardly to form an annular groove, the annular groove circles the aperture. The adhesive is disposed inside the annular groove, and the frame body and adhesive function together to block trap and hold any dust present during manufacture of the camera module, to avoid an image quality which is less than optimal.
