Adjustable Aperture Camera Device with Dust-Proof Shutter Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional camera devices with adjustable apertures face challenges in preventing dust from entering the aperture adjusting mechanism and have a thick design, making it difficult to integrate such functionality into mobile devices like smartphones, where space and thickness are critical.
Innovation Solution
A camera device design featuring an optical system frame with a shutter blade mechanism that adjusts the aperture, where the shutter blade is positioned between the cover plate and the bottom plate, and a transparent plate forms an accommodating space to prevent dust entry and reduce thickness by allowing more room for components, enabling aperture adjustment and depth of field control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the transparent plate is just adhered to an external surface of the external shell for convenience of manufacture, then the manufacturing process is simple, but dust can fall into the blade room of the aperture adjusting device
Solution Approach 1:
The transparent plate is divided into two functional parts: a first transparent plate adhered to the external shell for dust protection, and a second transparent plate forming the front surface of the aperture adjusting device. This segmentation allows each part to serve its specific function while maintaining manufacturing simplicity.
Solution Approach 2:
A supporting base is introduced as an intermediary component between the aperture adjusting device and the external shell. The supporting base provides a dedicated mounting structure that prevents dust entry into the blade room while maintaining the simplicity of the overall manufacturing process.
2Adaptability or versatility
If the aperture adjusting device is deployed into the mobile terminal to enable aperture adjustment, then the depth of field control is improved, but the thickness of the mobile terminal increases
Solution Approach 1:
The aperture adjusting device is merged with the existing camera lens assembly by integrating it into the optical path between the lens and the image sensor. This combination allows aperture adjustment functionality to be added without requiring separate space, thereby controlling the overall device thickness.
Solution Approach 2:
The aperture adjusting device is positioned in the optical path dimension rather than adding thickness in the vertical dimension. By utilizing the existing space along the optical axis, the design achieves aperture control without increasing the overall thickness of the mobile terminal.
3Adaptability or versatility
If the shutter blade is positioned between the cover plate and the bottom plate to adjust aperture, then the aperture control is achieved, but the device thickness increases
Solution Approach 1:
The shutter blade mechanism is nested within the space between the cover plate and the bottom plate, utilizing the existing structural volume. The aperture adjusting device is positioned such that it fits within the available space without requiring additional thickness, achieving aperture control through efficient spatial utilization.

AI summary
A camera device is packaged inside an external shell of an electronic apparatus. The external shell has an opening. The camera device has a transparent plate, a part of which is adjacent to the opening of the external shell. The transparent plate forms an accommodating space for accommodating other components of the camera device. Thus, the dust can be prevented from falling into a shutter blade room of the camera device. The camera device also includes a shutter blade, a driver, and a plate. The plate has an aperture, and the aperture of the camera device is defined thereby. The aperture of the plate is completely pervious to light when the shutter blade is at a first position, and the aperture of the plate is partially pervious to light when the shutter blade is at a second position, thereby changing the aperture of the camera device.
