Ventricular Connecting Assembly With Adjustable Split-Ring Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The operation of current ventricular connecting assemblies is cumbersome, causing inconvenience during the mounting of blood pumps.
Innovation Solution
A ventricular connecting assembly featuring a clamping assembly with a split ring and adjustable inner diameter, facilitated by a locking mechanism that adjusts the relative positions of connecting arms, allowing for easy clamping and unclamping of the inlet tube of the blood pump.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional ventricular connecting assembly is used to fix the blood pump, then the blood pump can be securely mounted, but the operation becomes cumbersome and inconvenient
Solution Approach 1:
The split ring is designed with adjustable inner diameter that can switch between clamping and non-clamping states, transforming a static structure into a dynamic one that adapts to different operational requirements, thereby improving ease of operation while maintaining secure mounting
2Ease of operation
If the split ring inner diameter is made adjustable to facilitate mounting, then the ease of operation improves, but the device complexity increases
Solution Approach 1:
The locking assembly integrates multiple functions (adjusting relative positions of connecting arms, maintaining clamped state, and controlling split ring inner diameter) into a single rotational mechanism, which simplifies the overall device structure while achieving adjustable inner diameter for easier operation
