Vertical Pump Clamp Locking for Secure Repositioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pump body installation devices in ECMO systems lack simplicity and convenience in adjusting the pump body position after installation, with complex operations and subjective locking mechanisms that compromise safety and efficiency.
Innovation Solution
A vertical quick clamping and fixing device featuring a fixing seat with a mounting groove, a locking block with a connecting part that rotates within the groove, and elastic positioning parts that guide and secure the pump body into place, allowing for easy repositioning and secure locking through a rotating mechanism with guided surfaces and elastic components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional locking mechanism with multiple rotations is used, then the locking is secure, but the operation becomes complex and time-consuming
Solution Approach 1:
The locking mechanism is segmented into distinct functional components: the rotating member with limiting piece for locking action, and the elastic positioning part with guide surfaces for positioning. This segmentation allows each component to perform its specific function efficiently, reducing overall operational complexity while maintaining security
Solution Approach 2:
The mechanism transitions from static to dynamic operation through the rotating member that can rotate to engage or disengage the limiting piece. The elastic positioning part dynamically adjusts during insertion and rotation, providing both guidance and locking in a single continuous motion rather than multiple discrete steps
2Device complexity
If finger tightening is used for locking, then the mechanism is simple, but the tightening degree is subjective and safety is compromised
Solution Approach 1:
The guide surfaces provide tactile feedback during insertion, guiding the elastic positioning part into the correct position in the mounting groove. The limiting piece on the rotating member provides mechanical feedback through engagement and disengagement, giving clear indication of locked vs. unlocked states, eliminating subjective judgment
Solution Approach 2:
The elastic positioning part automatically positions itself along the guide surfaces during insertion, and the rotating member self-locks when rotated to the appropriate position. The mechanism serves itself by providing automatic positioning and locking without requiring subjective human judgment about tightening degree
3Stability of the object's composition
If the pump body is fixedly installed, then the installation is stable, but the position cannot be adjusted after installation
Solution Approach 1:
The connecting part is designed to be rotatable within the mounting groove, transforming the installation from a static fixed position to a dynamic adjustable position. The rotating member with limiting piece maintains stability during rotation through controlled engagement, allowing position changes while preserving installation security
Solution Approach 2:
The mounting groove and connecting part combination serves multiple functions: it provides stable fixation when the connecting part is stationary, allows position adjustment when rotated, and maintains locking security through the limiting piece. This multi-functionality resolves the contradiction between stability and adjustability
