Balloon Mounting Jig With Sliding Surface For Endoscope
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing balloon mounting jigs for endoscopes are cumbersome and time-consuming to operate, often resulting in wrinkles on the balloon and difficulty in maintaining its position during insertion.
Innovation Solution
A balloon mounting jig with a hollow cylindrical main body and pair of guide pieces that have a sliding surface for easy insertion and removal of the endoscope insertion part, reducing friction and tension on the balloon.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the balloon is moved by gripping the guide pieces and dragging it with frictional force, then the balloon can be positioned on the insertion part, but wrinkles are likely to occur on the balloon
Solution Approach 1:
A sliding member is introduced as an intermediary between the operator's gripping action and the balloon. The sliding member has a smooth sliding surface that contacts the balloon, allowing the balloon to be moved along the insertion part without direct friction from gripping the guide pieces, thereby preventing wrinkles while maintaining ease of operation
Solution Approach 2:
The function of moving the balloon is extracted from the guide pieces and assigned to a separate sliding member. This separates the guiding function (guide pieces) from the moving function (sliding member), allowing the guide pieces to remain stationary while the sliding member carries the balloon along the insertion part without causing wrinkles
2Reliability
If the first guide piece and the second guide piece are pulled out from the balloon, then the balloon can be positioned, but the position of the balloon easily shifts
Solution Approach 1:
The sliding member is designed with engagement structures that preliminarily secure the balloon position before the guide pieces are removed. The sliding member maintains the balloon in the correct position during the entire process, and only after the balloon is properly positioned and secured does the sliding member allow the guide pieces to be pulled out, preventing position shifts
Solution Approach 2:
The sliding member acts as an intermediary that maintains balloon position stability throughout the mounting process. It provides continuous support and positioning guidance, preventing the balloon from shifting when the guide pieces are removed, thereby maintaining reliability while managing device complexity
3Ease of operation
If the balloon is moved by frictional force between the insertion part and the balloon, then the balloon can be positioned, but it is difficult to move the guide pieces due to balloon tension
Solution Approach 1:
The sliding member serves as an intermediary that reduces the direct transmission of balloon tension to the guide pieces. The sliding surface between the sliding member and the balloon allows for smooth movement with reduced friction, enabling the guide pieces to be moved more easily despite the balloon tension
Solution Approach 2:
The friction-based mechanical interaction between the guide pieces and balloon is replaced with a sliding mechanism. The sliding member introduces a low-friction interface that substitutes the high-friction direct contact, reducing the force required to move the guide pieces against balloon tension

Function Achieved in This Case
The jig allows for effortless movement and positioning of the balloon on the endoscope insertion part, reducing the risk of wrinkles and improving operational efficiency.
Implementation Method 1
a sliding surface on which an outer peripheral surface of the insertion part or the insertion assisting tool is slidable is provided on inner surfaces of the main body and the pair of guide pieces
