Dust-Sticking Optical Filtering Module for Camera Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The light filtering piece in camera lenses is prone to dust accumulation, leading to poor imaging quality and instability, as it is directly installed inside the base and lacks effective dust removal mechanisms.
Innovation Solution
A dust-sticking optical filtering module is introduced, featuring a base with a light-transmitting space, a slidably positioned light filtering assembly, and a dust-sticking plate at the base's bottom to capture dust, along with a thermally conductive silica gel plate for heat management and improved dust adhesion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the light filtering piece is installed directly inside the base, then the structure is simple, but dust accumulates on the light filtering piece causing poor imaging quality
Solution Approach 1:
The base is divided into an upper base and a lower base that can be separated. The light filtering assembly is positioned between them, allowing the lower base to be removed for dust collection without affecting the light filtering function. This segmentation enables independent access to the dust-sticking plate while maintaining the integrity of the optical path.
Solution Approach 2:
A dust-sticking plate is introduced as an intermediary component between the light filtering piece and the base. This plate with adhesive surface captures dust particles before they can settle on the light filtering piece, thereby protecting the imaging quality without requiring complex dust removal mechanisms.
2Ease of manufacture
If the light filtering piece is installed directly inside the base, then the installation is simple, but the device stability is poor
Solution Approach 1:
The base is segmented into upper and lower parts that can be easily assembled and disassembled. The light filtering assembly is positioned in a designated space between them, providing stable positioning while allowing convenient access for maintenance and dust collection operations.
Solution Approach 2:
The dust-sticking plate serves as a mediator that stabilizes the light filtering assembly by providing a dedicated mounting surface. This separate plate ensures the light filtering piece remains securely positioned while allowing the lower base to be removed for dust collection without disturbing the optical components.
3Manufacturing precision
If a dust-sticking plate is added to the base, then dust can be effectively captured, but the device complexity increases
Solution Approach 1:
The dust-sticking plate is merged with the lower base as an integrated component. The plate is positioned at the bottom of the light-transmitting space and is removed together with the lower base, eliminating the need for separate dust collection mechanisms and reducing overall structural complexity.
Solution Approach 2:
The dust-sticking plate uses its own adhesive surface to automatically capture dust particles that enter the light-transmitting space. This self-service mechanism eliminates the need for external dust removal devices, motors, or complex control systems, maintaining simplicity while effectively protecting imaging quality.
4Adaptability or versatility
If the light filtering assembly is made slidable, then the light aperture can be adjusted, but dust accumulation during sliding affects imaging
Solution Approach 1:
The dust-sticking plate acts as a mediator that intercepts dust particles during the sliding motion of the light filtering assembly. As the assembly slides to adjust aperture, any dust that becomes airborne is captured by the adhesive surface of the plate, preventing it from settling on the light filtering piece and maintaining imaging quality throughout the adjustment process.
