Endoscope Operation Portion Partitioning Board and Position Regulating Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During the assembly of endoscope internal components, there is a challenge in maintaining the correct arrangement and preventing overlap, which can lead to functional issues such as deformation of tubes, signal line breakage, and reduced illumination due to the elasticity and slackness of components like fluid tubes, light guide fiber bundles, and signal cables within the operation portion.
Innovation Solution
An endoscope design featuring a partitioning board and an endoscope internal component position regulating member with predetermined resilience, which partitions the operation portion's internal space into specific areas to guide and regulate the placement of bending wires, fluid tubes, light guide fiber bundles, and signal cables, preventing overlap and maintaining slackness for easy reciprocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fluid tubes, light guide fiber bundles, and signal cables are arranged in the operation portion internal space with slackness to enable reciprocation, then the components can move freely during bending operations, but the components may overlap or contact with each other causing deformation, signal line breakage, or reduced illumination
Solution Approach 1:
The operation portion internal space is divided into multiple regulated spaces by the position regulating member, which has a through hole. This segmentation separates different components (fluid tubes, light guide fiber bundles, signal cables) into distinct zones, allowing each to reciprocate independently without overlapping or contacting others, thus maintaining both freedom of movement and component integrity
Solution Approach 2:
The position regulating member acts as an intermediary structure between the components and the operation portion housing. It provides regulated spaces that guide component movement and prevent harmful contacts, enabling reciprocation while protecting against deformation and breakage
2Device complexity
If the operation portion internal space is used to accommodate all endoscope internal components, then the components can be integrated in a compact structure, but it becomes difficult to maintain correct arrangement and prevent overlap during assembly
Solution Approach 1:
The position regulating member divides the operation portion internal space into regulated spaces with specific geometries. Each regulated space is designed to accommodate specific components in predetermined positions, providing assembly guidance that ensures correct arrangement while maintaining compact integration
Solution Approach 2:
The position regulating member is pre-installed in the operation portion before component assembly. Its regulated spaces with through holes are prepared in advance to guide component placement, making assembly easier and more precise by providing built-in positioning features
3Ease of manufacture
If the position regulating member has predetermined resilience to regulate component positions, then components can be easily regulated during assembly, but the structure becomes more complex
Solution Approach 1:
The position regulating member is designed with predetermined resilience, meaning its physical parameter (elasticity) is optimized during manufacturing. This allows the component to provide regulatory function through its material property rather than complex mechanical structures, achieving ease of assembly without excessive structural complexity
