Camera Module Sealing Assembly to Prevent Lens Condensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The issue of water droplets or water marks inside camera modules due to condensation and temperature differences, which affect image clarity and product perception, cannot be resolved by external cleaning and pose a significant challenge in the industry.
Innovation Solution
A camera module design that includes a frame, appearance component, and transparent cover, sealed with waterproof adhesive layers, where the transparent cover is attached in a non-aqueous airtight cavity to prevent moisture entry during assembly, using a vacuum or nitrogen-filled environment to maintain dryness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the camera module is assembled in a normal environment, then the assembly process is simple and fast, but water droplets and water marks form inside the lens due to condensation
Solution Approach 1:
The patent applies the inert atmosphere principle by assembling the camera module in a non-aqueous airtight cavity (such as a vacuum or nitrogen-filled environment). This prevents moisture from the external environment from entering the camera module during assembly, thereby avoiding condensation and water mark formation on the lens while maintaining efficient production
2Reliability
If the camera module structure is sealed completely, then moisture is prevented from entering, but the lens cannot be exposed for imaging
Solution Approach 1:
The patent applies the flexible shell principle by using a transparent cover (lens cover) made of waterproof and airtight material that selectively seals the camera module. This cover allows the lens to be exposed for imaging while preventing moisture and water from entering the internal cavity, thus resolving the contradiction between sealing and lens exposure
3Reliability
If the transparent cover is attached after assembly, then the lens opening can be sealed, but moisture may have already entered during assembly
Solution Approach 1:
The patent applies the preliminary action principle by performing the entire assembly process including transparent cover attachment within a non-aqueous airtight cavity before exposure to the external environment. This preliminary sealing in a controlled environment prevents moisture ingress that would otherwise occur during subsequent handling and assembly steps
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively prevents water droplets and water marks inside the camera module, improving yield and performance by ensuring a moisture-free assembly process.
Implementation Method 1
A camera module includes a frame, a camera body, an appearance component, and a transparent cover... use elements such as a frame, an appearance component, and a waterproof adhesive layer to encapsulate the camera body
Implementation Method 2
The initial camera module is placed in a non-aqueous airtight cavity... the process of attaching the transparent cover is performed in the non-aqueous airtight cavity to prevent external water and/or moisture from entering the frame during assembly

AI summary
A camera module includes a frame, a camera body, an appearance component, and a transparent cover. The frame includes a first opening. The camera body is disposed in the frame and includes a lens. The first opening corresponds to and exposes the lens. The appearance component is disposed on the frame and includes a second opening corresponding to and exposing the lens and a framing portion protruding from a top surface of the appearance component and framing the second opening. The transparent cover is engaged with the framing portion and covers the lens.
