Dual-Lens Module Synchronous Movement for Wide-Angle Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera lenses with a single lens module have limited photographing range, making it difficult to capture entire thin and high or wide objects without changing focal length, which can result in reduced image quality.
Innovation Solution
A dual-lens module with independent receiving spaces and lens sets within a lens tube, where both lens sets have parallel optical axes and move synchronously, allowing for an enlarged photographing range without adjusting focal length.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a single lens module is used, then the device structure is simple, but the photographing range is limited and cannot capture entire thin and high or wide objects
Solution Approach 1:
The patent divides the single lens module into two independent lens sets (first lens set and second lens set) with different optical axes. Each lens set can capture a specific portion of the scene, and by combining the images from both lens sets, the overall photographing range is expanded to capture entire thin and high or wide objects that a single lens cannot capture
2Area of moving object
If the focal length is changed to capture the whole object, then the photographing range is improved, but the definition of the obtained image is lowered
Solution Approach 1:
Instead of using a single lens with adjustable focal length that compromises image quality, the patent segments the imaging function into two fixed-focus lens sets. Each lens set maintains optimal focus for its specific field of view, and the combination of both images provides full coverage without sacrificing image definition through focal length changes
3Area of moving object
If dual lens sets are added, then the photographing range is enlarged, but the device complexity increases
Solution Approach 1:
The patent merges two lens sets into a single integrated lens tube structure, where both lens sets share common components such as the lens tube, support plate, and driving mechanism. This combining approach enlarges the photographing range while minimizing the increase in device complexity through shared structural elements
Solution Approach 2:
The dual-lens module is designed with multi-functionality, where the first and second lens sets can capture different portions of the scene simultaneously. The module can photograph both thin and high objects and wide objects by utilizing the different optical axes and fields of view of the two lens sets, providing versatile imaging capabilities in a single device
