Switching Aperture with Variable Connecting Member for Camera Magnification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional optical lens systems for cameras face difficulties in performing magnified image formation functions due to issues with focal depth and image clarity when attempting to magnify objects, leading to blurred images and increased complexity in adding separate lens systems for magnification.
Innovation Solution
Incorporating a switching aperture with a variable connecting member, such as an electro-active polymer or piezoelectric material, that adjusts the width of the light beam to increase focal depth, allowing for selective formation of captured or magnified images by controlling the aperture's opening through a power supply state, eliminating the need for additional lens systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate lens system for magnifying object is detachably provided in a front surface of an optical lens system for camera, then object magnification functions can be performed, but the device complexity increases and portability deteriorates
Solution Approach 1:
The patent combines the magnification function with the existing camera lens system by providing a magnification lens that can be integrated into the front surface of the optical lens system. This merging approach allows the device to perform both camera functions and magnification functions without requiring completely separate systems, thereby reducing overall device complexity while maintaining versatility.
Solution Approach 2:
The optical lens system is designed to serve multiple functions: it can operate as a standard camera for capturing images and as a magnification device when the magnification lens is engaged. This multi-functionality is achieved through a unified design where the same optical components serve different purposes based on configuration, eliminating the need for entirely separate dedicated systems.
2Adaptability or versatility
If the object is brought close to the optical lens system for object magnification, then magnification is achieved, but the focal depth decreases and image clarity deteriorates
Solution Approach 1:
The patent employs a movable magnification lens that can be dynamically adjusted in position relative to the object and the image sensor. This dynamic adjustment capability allows the system to maintain proper focal depth and image clarity across different magnification levels by actively repositioning the lens to optimize the optical path, rather than relying on a fixed lens position that would compromise image quality.
