Vehicle Camera Module Packing Member Segmentation for Assembly Adhesion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Camera modules for vehicles face challenges in maintaining waterproofing performance due to exposure and require improved adhesion and mounting stability to prevent detachment during assembly.
Innovation Solution
A camera module design featuring a packing member with inwardly protruded support parts and a ring-shaped structure, including a hitching part and connection part, to enhance adhesion and prevent detachment between the front and rear bodies, utilizing silicone or rubber materials for sealing and secure mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a packing member is used for sealing between front and rear bodies, then waterproofing performance is improved, but the packing member may detach during assembly reducing reliability
Solution Approach 1:
The packing member is divided into multiple functional segments: a ring-shaped body for sealing, and multiple support parts (first support part with through hole, second support part with hitching part and connection part) for mounting. This segmentation allows the sealing function and mounting function to be independently optimized while working together as an integrated solution.
Solution Approach 2:
The support parts are integrated within the ring-shaped packing member structure. The first support part is positioned at the first lateral surface with its through hole, while the second support part is positioned at the second lateral surface with the hitching part and connection part nested into the ring structure, creating a compact integrated component.
2Reliability
If the packing member is securely mounted to prevent detachment, then reliability is improved, but adhesionability during assembly deteriorates
Solution Approach 1:
Different regions of the packing member have different properties optimized for their specific functions: the ring-shaped body provides continuous sealing contact, the first support part with through hole provides localized mechanical anchoring, and the second support part with hitching part provides localized engagement features. This local quality differentiation resolves the conflict between secure mounting and ease of assembly.
Solution Approach 2:
The support parts act as intermediary elements between the packing member and the housing structures. The first support part mediates between the packing member and the first housing through the through hole, while the second support part mediates between the packing member and the second housing through the hitching part and connection part, facilitating secure yet manageable assembly.

AI summary
The exemplary embodiment of the present disclosure relates to a camera module including a rear-opened front body, a rear body coupled to a rear side of the front body to form an inner space, a lens part coupled to the front body, an image sensor accommodated at the inner space to convert a light having passed the lens part to an electrical signal, a PCB (Printed Circuit Board) accommodated at the inner space and mounted with the image sensor, and a closed curve-shaped packing member interposed between the front body and the rear body, wherein the packing member includes a support part extensively formed from the packing member to an inner side, and the front body or the rear body includes a support part accommodation groove having a shape corresponding to that of the support part, whereby adhesionability during assembly of packing member can be maximized to thereby minimize an installation defect, a depressed or stamped phenomenon of a packing member that may occur during assembly process.
