Solution Overview

Problem

Endoscopes require frequent replacement of endoscope tubes to accommodate different diameters, which is cumbersome and inefficient, especially in bronchoscopy where thicker devices are needed for stent insertion and ventilation connections must be reattached, making it difficult to switch between smaller and larger diameters without significant effort.

Innovation Solution

A medical device with a detachable endoscope head featuring a longitudinal channel and radially arranged measuring channels that can be connected to a quick-coupling measuring adapter, allowing for easy attachment and detachment without tools, enabling the use of different endoscope tubes with adapter sleeves for diameter compensation, ensuring secure and gas-conducting connections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the entire endoscope tube is replaced to switch between different diameters, then the correct diameter for the application is achieved, but the time and effort required for replacement and reconnection increases significantly

Engineering Contradiction:
Improveability to use different endoscope tube diametersVSAvoidtime required for tube replacement and reconnection
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The endoscope system is divided into separate modular components: the endoscope head and the endoscope tube can be independently detached and reconnected. This segmentation allows the tube to be replaced without replacing the entire endoscope assembly, reducing time loss while maintaining adaptability to different tube diameters.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The endoscope head is designed with universal connection interfaces that can accommodate multiple tube diameters (e.g., 10mm, 12mm, 14mm, 16mm) through standardized coupling mechanisms. This multi-functionality allows a single endoscope head to work with various tube sizes, eliminating the need to replace the entire system when changing tube diameters.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If thicker endoscope tubes are used for stent placement, then the ability to place stents is enabled, but the handling difficulty and required practice increase

Engineering Contradiction:
Improveability to place stentsVSAvoidhandling ease
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The connection interface between the endoscope head and tube incorporates dynamic elements such as spring-loaded clamping mechanisms that automatically adjust to different tube thicknesses. This dynamic adaptation allows the system to maintain secure connections while accommodating varying tube diameters, reducing the handling difficulty associated with thicker tubes.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If multiple measuring channels are included in the endoscope head, then measurement capabilities are enhanced, but the complexity of connecting each channel individually increases

Engineering Contradiction:
Improvemeasurement capabilityVSAvoidconnection complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Multiple measuring channels are merged into a single integrated connection interface. The coupling mechanism between the endoscope head and tube combines multiple channel connections into one unified attachment action, allowing all measuring channels to be connected simultaneously through a single plug-in movement rather than requiring individual connection of each channel.

Inventive Principle:
Principle #5Merging (Combining)
