Camera Module Protrusion Bonding for Contamination Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera modules are vulnerable to contamination by external foreign substances due to their sealed structure, which can compromise the integrity of internal components.
Innovation Solution
A camera module design featuring a first body with a protrusion and coupling groove, and a second body with a protrusion and coupling groove, along with adhesive members on the inner and outer surfaces of the second protrusion, including holes or grooves to increase adhesive placement area, ensuring a firm coupled state.

Engineering Contradiction Analysis
1Object-affected harmful factors
If a sealed structure is used to protect internal components, then protection against contamination is improved, but the coupling stability between bodies deteriorates
Solution Approach 1:
The invention transitions from a simple planar adhesive application to a three-dimensional adhesive distribution by adding protrusions with multiple surfaces (inner surface, upper surface, outer surface) and incorporating holes/grooves. This dimensional expansion allows adhesive to be placed on multiple surfaces simultaneously, increasing total adhesive area and improving coupling stability while maintaining the sealed protective structure.
Solution Approach 2:
The adhesive placement area is segmented into multiple distinct surfaces (inner surface, upper surface, outer surface of the protrusion) rather than a single continuous area. This segmentation allows adhesive to be distributed across multiple locations, creating multiple bonding points that collectively enhance coupling stability between the first and second bodies.
2Stability of the object's composition
If adhesive members are placed on multiple surfaces of the protrusion, then coupling stability is improved, but manufacturing complexity increases
Solution Approach 1:
The protrusion structure with its multiple surfaces and integrated holes/grooves is pre-formed as part of the molding process. This preliminary formation of the complex geometry allows subsequent adhesive application to occur on multiple pre-positioned surfaces without requiring complex assembly steps, thereby improving coupling stability while limiting the increase in manufacturing complexity.

AI summary
This camera module comprises: a first body including a lens; a second body coupled to the first body; and a printed circuit board which is disposed in a space inside the first body and the second body and includes an image sensor. The first body includes: a first protrusion protruding downward from the lower surface; and a first coupling groove located inside the first protrusion. The second body includes: a second protrusion protruding upward from the upper surface and facing the first coupling groove; and a second coupling groove located outside the second protrusion and facing the first protrusion. Adhesive members are arranged on the inner surface, the upper surface, and the outer surface of the second protrusion, and the second protrusion has one or more grooves or holes for arranging the adhesive members.
