Rigid Endoscope Camera Integration Without an Eyepiece Group
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rigid endoscopes used in clinical diagnosis and treatment have high application penetration and market share due to their unique advantages in image quality and cost performance, but they often include redundant components like the eyepiece group and mechanical structures that increase processing and assembly costs.
Innovation Solution
The endoscope system integrates a rigid endoscope with a camera system, removing the eyepiece group and associated mechanical structures by using a photographic objective lens group to directly magnify and image the relay image, and an image sensor to convert the magnified image into an electrical signal, thereby reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the rigid endoscope includes traditional components like eyepiece group and mechanical structures, then the image quality and reliability are maintained, but the processing and assembly costs increase
Solution Approach 1:
The patent extracts and removes the eyepiece group and associated mechanical structures (eye mask, connection interface) from the rigid endoscope system. The connection housing is designed to be directly connected to the external lens tube without these intermediate components, simplifying the overall structure while maintaining the core imaging function through the camera system attachment.
Solution Approach 2:
The connection housing is designed with universal functionality to accommodate different camera systems through detachable connection. This single component serves multiple purposes: structural support, optical path transmission, and interface for various imaging devices, replacing the need for specialized mechanical structures and eye masks.
2Ease of manufacture
If the eyepiece group and associated mechanical structures are removed, then the processing and assembly costs are reduced, but the image transmission path may be affected
Solution Approach 1:
The connection housing serves as an intermediary component that maintains the optical path stability. It provides a stable mounting structure for the camera system and ensures proper alignment with the external lens tube, compensating for the removal of traditional mechanical structures while maintaining image transmission reliability.
Solution Approach 2:
The patent replaces the traditional mechanical eyepiece observation system with an electronic camera system. The image transmission function is maintained through the optical interface between the external lens tube and camera system, substituting mechanical eye mask structures with a detachable camera connection interface.
