Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging and laser ranging devices are bulky due to the external mounting of the laser ranging device, which increases the size and reduces portability.
Innovation Solution
A compact ranging and imaging integrated lens is designed with an infrared imaging part and a ranging part, where the laser transmitting and receiving lens sets are mounted on the edge of the lens holder, separated from each other, and the control processing module is positioned behind the lens holder, minimizing external protrusions and reducing interference with the imaging path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the laser ranging device is externally mounted on the optical observation device, then the ranging function is achieved, but the external size increases and portability is reduced
Solution Approach 1:
The patent integrates the laser ranging device and optical observation device into a single unified structure. The laser transmitting lens set and receiving lens set are mounted on the lens holder of the optical observation device, merging two previously separate devices into one integrated system, thereby achieving ranging function without increasing external size
2Reliability
If the laser ranging device is externally mounted, then the ranging function is achieved, but the device complexity increases
Solution Approach 1:
The patent combines the laser ranging device with the optical observation device by mounting the laser transmitting and receiving lens sets on the existing lens holder structure. This merging approach integrates multiple functions into a single device, reducing overall structural complexity while maintaining full ranging functionality
3Measurement precision
If the laser transmitting and receiving lens sets are separated and mounted on the lens holder edge, then mutual interference is reduced and ranging accuracy is improved, but the manufacturing complexity increases
Solution Approach 1:
The patent divides the laser ranging system into separate transmitting and receiving lens sets, positioning them at different locations on the lens holder edge. This segmentation prevents mutual optical interference between the two systems, improving ranging accuracy while maintaining manageable manufacturing complexity through modular assembly
4Manufacturing precision
If the control processing module is positioned behind the lens holder, then the infrared imaging light path is not blocked and imaging quality is maintained, but the device integration complexity increases
Solution Approach 1:
The patent positions the control processing module in the axial direction behind the lens holder, utilizing the depth dimension rather than occupying the lateral imaging path. This spatial arrangement in another dimension allows the control module to be integrated without blocking the infrared imaging light path, maintaining imaging quality while achieving functional integration

AI summary
A compact ranging and imaging integrated lens includes an infrared imaging part and a ranging part. The ranging part is integrated in an infrared imaging lens, and a laser transmitting lens set and a laser receiving lens set are mounted on an edge of a lens holder and separated from each other, such that the laser transmitting lens set and the laser receiving lens set will not occupy space beyond the area where a first lens is located, and will not form obvious protrusions on the outside of the compact ranging and imaging integrated lens, thus making the compact ranging and imaging integrated lens more compact in overall structure, reducing the influence on infrared imaging and mutual interference between components, and improving the ranging accuracy of the compact ranging and imaging integrated lens.
