Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional roller pump devices require multiple steps and component removal for inserting and removing tube pieces, making the process cumbersome.
Innovation Solution
A tube retention device with pivotably coupled clamp components that rotate in opposite directions in response to tube force, allowing easy insertion and removal of tube pieces by manual pressing and lifting, and featuring a detachable design for accommodating different tube diameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional tube retention mechanisms with multiple components are used, then the tube piece can be securely retained, but the insertion and removal process becomes complex and time-consuming
Solution Approach 1:
The clamp is divided into two separable clamp components (first and second) that can be independently positioned and adjusted. Each clamp component can be separately engaged with the tube, allowing for simplified insertion where the tube can be guided between the components, and easier removal where components can be independently disengaged.
Solution Approach 2:
The clamp components are made movable relative to each other along the tube axis, transitioning between a closed position (for secure retention) and an open position (for easy insertion/removal). This dynamic capability allows the device to adapt its state based on operational needs, simplifying the overall process.
2Adaptability or versatility
If a fixed retention device is used, then the structure remains stable, but switching between different tube diameters requires complete device removal and reinstallation
Solution Approach 1:
The clamp components are designed to be movable and adjustable, allowing them to adapt to different tube diameters without requiring complete device disassembly. The components can be positioned at different locations along the tube, enabling quick adaptation to various tube sizes while maintaining structural stability during operation.
Solution Approach 2:
The retention device is designed to accommodate multiple tube diameters using the same basic structure. The adjustable clamp components can be repositioned to fit different tube sizes, making the device universal and eliminating the need for complete removal and reinstallation when switching tubes.
3Reliability
If multiple clamp components are used to secure the tube, then the tube retention is more reliable, but the device structure becomes more complex
Solution Approach 1:
The clamp is segmented into two main components that work together to secure the tube. This segmentation provides reliable retention through dual-point contact while keeping each component relatively simple in structure, avoiding the need for multiple complex mechanisms.
Solution Approach 2:
The first and second clamp components are combined with the block structure to form an integrated retention system. The components work together synergistically, with each performing a specific function, to achieve reliable tube retention without requiring additional separate mechanisms.

Function Achieved in This Case
Facilitates quick attachment and removal of tube pieces to roller pump heads, reducing operational complexity and enabling seamless switching between tube sizes without removing the entire retention device.
Implementation Method 1
the first and second clamp components may be configured to rotate, in opposite directions and in response to application of force by a tube piece upon the first and second tube-engagement surfaces, from an open position to a closed position

AI summary
A tube retention device includes first and second wall surfaces having a first attachment point and a second attachment point, respectively. A first clamp component, having a first tube-engagement surface, is pivotably coupled to the first wall surface at the first attachment point, and configured to rotate about an axis at least approximately normal to the first wall surface. A second clamp component, having a second tube-engagement surface, is pivotably coupled to the second wall surface at the second attachment point, and configured to rotate about an axis at least approximately normal to the second wall surface. The clamp components may be configured to rotate, in opposite directions and in response to application of force by a tube piece upon the tube-engagement surfaces, from an open position to a closed position, where the tube piece is retained between the clamp components when the clamp components are in the closed position.
