Variable Aperture Mechanism for Compact Camera Light Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable electronic devices with cameras often have limited size and thickness, leading to cameras without physical apertures, which restrict light adjustment and consequently limit their photographic capabilities.
Innovation Solution
A camera device with a variable aperture mechanism, adjustable via a physical force applied to a lever, utilizing a lens barrel, a movable carrier with magnets, and an aperture driving module to adjust the aperture hole area, allowing for optimal light control based on photography functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a physical aperture is included in the camera device, then light adjustment capability is improved, but device size increases
Solution Approach 1:
The variable aperture is nested within the lens barrel structure, with the aperture hole area integrated into the lens assembly. The first movable carrier containing the variable aperture is positioned within the lens barrel, allowing the aperture mechanism to occupy minimal space while still providing adjustable light control capability.
Solution Approach 2:
The aperture is designed as a variable aperture rather than a fixed structure. The aperture hole area can be dynamically adjusted by applying physical force to the lever, which moves the first movable carrier within the lens barrel. This dynamic design allows the same compact structure to provide multiple aperture settings for different photography functions.
2Volume of moving object
If the camera device is minimized in size, then portability is improved, but photographic capability deteriorates
Solution Approach 1:
The compact camera device incorporates a variable aperture mechanism that enables multiple photography functions within a minimized structure. The adjustable aperture hole area allows the same compact device to adapt to different photography modes (e.g., portrait, landscape, low-light) by controlling light entry, thus providing universal photographic capability without increasing device size.
3Measurement precision
If a variable aperture mechanism is added, then light control precision is improved, but device complexity increases
Solution Approach 1:
The aperture adjustment mechanism uses a simple lever system with magnet-coil interaction rather than complex multi-component mechanical linkages. The physical force applied to the lever creates magnetic interaction between the magnet member and coil, which moves the first movable carrier to adjust the aperture hole area. This magnetic-mechanical hybrid approach provides precise light control while minimizing the number of mechanical parts and overall system complexity.
