Camera Module Sealing Member for Impurity Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Miniaturization of camera modules leads to issues with fluid and adhesive impurities, such as burrs, entering the module during manufacturing, causing image pollution due to the lack of effective sealing mechanisms.
Innovation Solution
A camera module design featuring a sealing member made of elastically deformable materials like rubber or silicon, which is inserted into a concave groove on the base and deforms to create a seal with the cover can, preventing impurities from entering the internal space without the need for a separate sealing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If camera module is miniaturized to meet customer demand for smaller designs, then the size of the camera module is reduced, but fluid impurities and adhesive impurities can more easily enter and adhere to the image sensor and infrared cutoff filter, causing image pollution
Solution Approach 1:
A sealing member is pre-installed on the base at the location where the cover can will be attached, before the final assembly. This preliminary sealing preparation ensures that when the cover can is coupled to the base, impurities are already blocked from entering the internal space, preventing image pollution even in the miniaturized structure
Solution Approach 2:
A sealing member made of elastically deformable material is introduced as an intermediary element between the base and the cover can. This sealing member deforms during assembly to fill gaps and create a reliable seal, preventing impurities from entering the camera module's internal space where the image sensor and infrared cutoff filter are located
2Object-affected harmful factors
If a separate sealing process is added to prevent impurity inflow, then contamination is reduced, but the manufacturing process becomes more complex and time-consuming
Solution Approach 1:
The sealing function is merged with the assembly process itself. The sealing member is designed to be installed on the base and automatically seal when the cover can is coupled, combining the sealing action with the mechanical assembly operation. This eliminates the need for separate sealing steps such as coating or additional fastening operations
Solution Approach 2:
The sealing member is designed to automatically perform its sealing function during the normal assembly process. When the cover can is coupled to the base, the sealing member deforms and creates the seal without requiring external intervention or additional sealing operations. The assembly process itself provides the sealing action
3Object-affected harmful factors
If a sealing mechanism is implemented to block impurity inflow, then image pollution is prevented, but the device structure becomes more complex
Solution Approach 1:
A sealing member made of elastically deformable material is used to create a flexible seal between the base and the cover can. This flexible sealing approach effectively blocks impurity inflow while maintaining a simple structure that integrates easily into the camera module assembly
Solution Approach 2:
The sealing member is pre-installed on the base in a simple manner before the cover can is attached. This preliminary installation ensures that the sealing function is already in place, and the final assembly simply completes the seal through the coupling action, avoiding complex sealing mechanisms
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
This design effectively blocks the inflow of impurities, reducing the risk of image pollution and eliminating the need for additional sealing processes, thereby simplifying manufacturing and reducing the risk of contamination and faulty assemblies.
Implementation Method 1
the sealing member may be formed of an elastically deformable material, such as rubber or silicon... the sealing member may be elastically deformed in a flat shape by being pressured on an inner circumferential surface of the cover can
