Medical Gas Supply Device Threaded Fitting Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical gas supply devices face challenges due to the lack of a globally recognized standard for threaded connections, leading to increased production and warehouse costs and limited flexibility, requiring multiple models and installation modifications for different connectors.
Innovation Solution
A medical gas supply device with a threaded fitting that can be quickly adapted by releasing external fastening means, featuring two interchangeable threaded connectors complying with different standards, and a locking system using a pin and groove mechanism for easy replacement and production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single threaded connector type is used in the device, then the manufacturing cost is reduced and production is simplified, but the adaptability to different regional standards and user needs is limited
Solution Approach 1:
The threaded fitting is designed to incorporate multiple threaded connectors of different types (e.g., different thread pitches, diameters, or standards) within a single component. This allows the device to universally connect to various regional standards and user appliance types without requiring multiple separate device models, thereby improving adaptability while maintaining a single device structure.
2Adaptability or versatility
If multiple device models with different outlet fittings are produced to meet international market demands, then the adaptability to different standards is improved, but the production cost and warehouse costs substantially increase
Solution Approach 1:
Multiple threaded connector options are merged into a single threaded fitting component. Instead of producing separate device models for different markets, the invention combines multiple connector types (e.g., different thread specifications) within one fitting that can be configured or selected based on the required standard, thereby reducing production variety and associated costs while maintaining adaptability.
3Adaptability or versatility
If the threaded fitting is fixed and cannot be modified, then the device structure is simplified and more reliable, but the flexibility for end users to connect different appliance categories is limited
Solution Approach 1:
The threaded fitting is designed with dynamic characteristics, allowing it to be modified or reconfigured by end users based on their specific needs. This may include features such as removable sections, interchangeable connector elements, or adjustable configurations that enable users to adapt the fitting for different appliance types without requiring complex tools or procedures, thereby improving both flexibility and ease of operation.
