Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical endoscopes face challenges in acquiring high-quality images due to signal distortion and noise, and existing electronic endoscopes cause discomfort due to a large diameter tip end, leading to pain and rejection during insertion.
Innovation Solution
A micro endoscope camera module with an objective lens at the front end and an image capturing means supported at the rear, utilizing an illumination fiber to reduce the scope diameter and prevent backward displacement during assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the objective lens, image sensor, and light source are all provided at an inner end of a scope, then image acquisition capability is improved, but the diameter of the tip end portion becomes large causing discomfort during insertion
Solution Approach 1:
The endoscope is divided into two separate tube bodies: a first tube body containing the objective lens and a second tube body containing the image sensor and light source. This segmentation allows each component to be positioned optimally without requiring all components to be concentrated at the tip end, thereby reducing the tip diameter while maintaining image acquisition capability.
Solution Approach 2:
The image sensor is positioned along the longitudinal axis of the scope rather than being concentrated at the transverse tip end. By extending the optical path along the length of the scope rather than packing components at the end, the tip diameter is reduced while still achieving high-quality image capture.
2Device complexity
If the scope tube is not physically supported at the rear, then the structure is simpler, but the scope tube may be pushed backward during assembly or use
Solution Approach 1:
The second tube body is designed to support the first tube body at the rear end before assembly is completed. This preliminary support structure prevents backward displacement of the scope tube during the assembly process and during use, ensuring proper positioning without requiring complex additional support mechanisms.
3Length of moving object
If the illumination fiber is not guided into the scope tube, then the structure is simpler, but the scope diameter cannot be reduced
Solution Approach 1:
The illumination fiber is guided through and nested within the scope tube structure. The fiber passes through the first tube body and is positioned within the illumination hole, allowing the lighting function to be integrated into the existing tube structure without significantly increasing the outer diameter of the scope.
