Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fluid distribution sockets for medical gases and vacuum in hospitals face challenges in maintenance, waste reduction, and robustness, particularly in the tip guide's structure and manufacturing process, which generates metal waste and requires frequent disassembly and assembly.
Innovation Solution
A tip guide comprising a filtration element with a polymer support part and a metallic connection head, allowing for detachable attachment within a fluid distribution socket, reducing metal waste and ensuring robustness for frequent connections and disconnections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the tip guide is made entirely of metal material, then robustness for frequent connection/disconnection operations is improved, but metal waste during manufacturing increases
Solution Approach 1:
The tip guide is constructed using composite materials: the connection head is made of metal material (stainless steel or brass) to ensure robustness for frequent connection/disconnection operations, while the body is made of polymer material to reduce metal waste during manufacturing. This composite structure allows each part to be made from the most suitable material for its specific function.
2Ease of manufacture
If the tip guide structure is simplified for easier manufacturing, then ease of manufacture is improved, but robustness for frequent operations may deteriorate
Solution Approach 1:
The tip guide is divided into two separate parts: a connection head and a body, which are manufactured separately and then assembled together. This segmentation allows the connection head to be manufactured with metal material for robustness while the body can be manufactured with polymer material for ease of production, ultimately improving both manufacturing simplicity and robustness.
3Ease of repair
If the tip guide is designed for detachable attachment, then ease of maintenance is improved, but connection reliability may worsen
Solution Approach 1:
The tip guide is designed as a detachable, replaceable component with a simplified structure that allows for easy maintenance and replacement. The connection head with its threading mechanism enables straightforward attachment and detachment from the socket, facilitating quick maintenance while maintaining sufficient connection reliability for medical applications.
