Imaging Unit Light Guide for Mobile Close-Up Obstruction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In close-up imaging using mobile terminals, the illumination light from the lighting section is often obstructed by the close-up lens, leading to insufficient illumination of the imaging target.
Innovation Solution
An imaging unit with an optical member that guides illumination light from the lighting section around the side of the close-up lens, ensuring that light reaches the target without obstruction, and includes adjustable mechanisms for precise alignment and emission direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a close-up lens is attached to the imaging section for magnification imaging, then the imaging magnification is improved, but the illumination light from the lighting section is obstructed by the lens
Solution Approach 1:
The patent introduces a light guide member that extends illumination light in a new spatial dimension, routing light from the lighting section around the close-up lens to reach the imaging target. This dimensional approach allows light to bypass the lens obstruction rather than attempting to pass through or around it in the traditional plane, effectively resolving the contradiction between achieving magnification and maintaining illumination.
2Device complexity
If the lighting section is used as is for close-up imaging, then the device structure is simple, but illumination light is shaded by the close-up lens and insufficient light reaches the target
Solution Approach 1:
The patent introduces a light guide member as an intermediary component between the lighting section and the imaging target. This mediator component redirects and transports illumination light around the close-up lens, enabling light to reach the target without requiring fundamental changes to the existing lighting section structure, thus balancing added functionality with structural simplicity.
3Length of moving object
If illumination light is directed straight from the lighting section to the target, then the light path is short and simple, but the light path is blocked by the close-up lens
Solution Approach 1:
The patent segments the illumination path into multiple sections: light from the lighting section first enters the light guide member, then travels through the light guide member's internal structure, and finally exits to illuminate the target. This segmentation allows the light to navigate around the close-up lens obstruction while maintaining an efficient overall path, ensuring reliable illumination despite the extended routing.
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
The solution effectively prevents light obstruction, ensuring uniform illumination of the close-up target and improving image quality by directing light around the lens, thus enhancing the imaging system's performance.
Implementation Method 1
an optical member that guides illumination light from the lighting section, from the lighting section of the mobile terminal toward a side of the target rather than an end of the lens section on the side of the target
