Roller Pump Tube Clamp for Fast Insertion and Secure Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional roller pump devices require multiple steps and component removal for inserting and removing tube pieces, leading to inefficient operation.
Innovation Solution
A tube retention device with pivotable clamp components that rotate in response to tube force, allowing simple insertion and removal by pressing or lifting, and a lid that prevents clamps from opening when closed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional tube retention mechanisms with multiple components are used, then reliable tube retention is achieved, but device complexity and operational time increase
Solution Approach 1:
The clamp is divided into two separable clamp components that can independently engage with the tube retention block, allowing simplified assembly and disassembly while maintaining secure retention when engaged
Solution Approach 2:
The tube retention mechanism is extracted as a separate removable component from the pump head, enabling independent replacement and maintenance without affecting the entire pump system
2Reliability
If conventional fastening devices requiring multiple steps are used, then secure tube fastening is achieved, but operational efficiency decreases
Solution Approach 1:
The clamp components are pre-configured with engagement features that automatically align with the tube retention block, eliminating the need for manual alignment steps and enabling rapid one-handed operation
Solution Approach 2:
The clamp components are designed to transition smoothly between engaged and disengaged states through simple pressing or lifting motions, enabling rapid tube insertion and removal without complex manipulation
3Ease of operation
If removable tube retention mechanisms are used, then ease of tube replacement is improved, but risk of improper closure increases
Solution Approach 1:
The engagement features provide tactile and visual feedback when the clamp components are properly secured to the tube retention block, giving operators confirmation of correct assembly without requiring additional verification steps

Implementation Method 1
configured to rotate, in opposite directions and in response to application of force by a tube piece upon the tube-engagement surfaces
Implementation Method 2
a lid configured to engage the clamp components thereby preventing them from opening when the lid is closed

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.
