Solution Overview
Problem
Existing dialysis machines face challenges in detecting and locating leaks in fluid-carrying lines due to complex and expensive sealing connections, which can lead to measurement and calculation errors, and fail to pinpoint the exact location of leaks.
Innovation Solution
A leakage connection adapter with a universal inlet and outlet design, featuring a sealing ring that simplifies installation by pressing onto a wall without requiring precise alignment, ensuring a reliable seal and direct flow to a leak detector via gravity, eliminating accumulation points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex sealing connection is used to ensure reliable leak detection, then the sealing reliability is improved, but the device complexity and installation difficulty increase
Solution Approach 1:
The sealing connection is divided into separate components: a sealing ring (Dichtungsring) that can be pre-installed on the collection container opening, and a separate hose connection. This segmentation allows the sealing function to be isolated and simplified, reducing overall connection complexity while maintaining reliability.
Solution Approach 2:
The sealing ring is pre-installed on the collection container opening before the hose connection is attached. This preliminary action ensures that the sealing surface is already prepared and positioned correctly, eliminating the need for complex alignment procedures during final assembly and reducing installation difficulty.
2Reliability
If a complex sealing connection is used to ensure reliable leak detection, then the sealing reliability is improved, but the installation time and cost increase
Solution Approach 1:
By separating the sealing ring from the hose connection, the installation process is divided into simple, independent steps. The sealing ring can be quickly snap-fitted onto the opening, and the hose connection can be separately attached, significantly reducing installation time compared to a complex integrated connection system.
Solution Approach 2:
The sealing ring is designed as a simple, inexpensive component that can be easily replaced if needed. This approach reduces installation costs and allows for quick maintenance without requiring complex tools or extensive installation procedures.
3Reliability
If a complex sealing connection is used to ensure reliable leak detection, then the sealing reliability is improved, but the ease of operation deteriorates
Solution Approach 1:
The sealing ring is pre-positioned on the collection container opening, creating a ready-to-use sealing surface. This preliminary action eliminates the need for operators to perform complex alignment procedures during installation, making the operation simple and intuitive while ensuring reliable sealing.
Solution Approach 2:
The sealing ring is designed to self-align and self-seal when installed on the opening. The hose connection simply needs to be placed over the sealing ring, and the sealing action occurs automatically through the ring's geometry and material properties, requiring no additional adjustment or complex操作步骤 from the operator.
4Reliability
If a complex sealing connection is used to ensure reliable leak detection, then the sealing reliability is improved, but the manufacturing cost increases
Solution Approach 1:
The sealing function is isolated to a separate, simple sealing ring component that can be manufactured using standard molding or machining processes. This segmentation allows each component (sealing ring, hose connection, collection container) to be manufactured independently using optimal, cost-effective processes, reducing overall manufacturing cost compared to a complex integrated connection system.
Solution Approach 2:
The sealing ring is designed as a simple, inexpensive component with no complex features, making it suitable for cost-effective mass production. The simplicity of the design allows for low-cost manufacturing while still providing reliable sealing performance.
