Endoscopic Shaft Radial Control Train Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Endoscopic devices with deflectable shafts face challenges in maintaining the integrity and ease of maintenance of their deflection mechanisms, particularly due to complex threading requirements for control trains, which can lead to time-consuming and cumbersome procedures during production, maintenance, and repair.
Innovation Solution
The endoscopic device incorporates a second connection member with a passageway and radial opening for guiding and inserting the control train, allowing for radial insertion and simplifying the assembly and maintenance processes, potentially eliminating the need for complex threading and enhancing the security of the control train within the mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the control train is inserted through complex threading procedures, then the control train can be secured in the connection member, but the assembly and maintenance processes become time-consuming and cumbersome
Solution Approach 1:
The patent introduces a radial opening that allows the control train to be inserted radially into the connection member, changing the insertion direction from axial (threading) to radial. This dimensional change simplifies the assembly process while maintaining secure positioning of the control train within the connection member
2Ease of manufacture
If traditional threading procedures are used to insert the control train, then the control train can be secured, but the production and repair processes become complicated and time-consuming
Solution Approach 1:
The patent extracts the threading mechanism from the connection member design and replaces it with a radial opening and passageway system. This removal of the complex threading requirement simplifies both the manufacturing process and the overall device structure while maintaining the functional integrity of the control train integration
