Peristaltic Pump Dispenser Cassette With Elastic Cartridge Connector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispenser cassettes for peristaltic pumps have complex production and installation processes due to the need for individual attachment and tensioning of cartridges, leading to longer production times and inefficiencies.
Innovation Solution
A dispenser cassette design featuring a first and second cartridge connected by an elastic U-shaped connector, allowing for translational and rotational movement, which forms an integral component and reduces the need for separate tube tensioning, enabling easier operation and adaptation to different pump designs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a three-part construction with individual cartridges is used, then the dispenser cassette can be designed with separate functional modules, but the attachment and removal process becomes complex and time-consuming
Solution Approach 1:
The patent combines multiple cartridges into a single integrated cartridge assembly that is attached to the pump as one unit. The cartridges are arranged side-by-side and connected through a common base structure, allowing the entire assembly to be mounted or removed in a single operation rather than individually attaching each cartridge. This merging approach maintains the modular functional design while eliminating the complexity of multiple attachment steps.
2Reliability
If tubes are individually tensioned and attached to each cartridge, then the medium can be conveyed effectively, but the production and installation process becomes complicated and time-consuming
Solution Approach 1:
The tubes are pre-attached to the cartridges during the manufacturing process, with proper tensioning and positioning already established. The cartridge assembly is produced as a pre-configured unit where all tube connections are made and tested before delivery to the customer. This preliminary action eliminates the need for complex on-site tube attachment and tensioning, significantly reducing installation time and complexity while maintaining reliable medium conveyance.
Solution Approach 2:
Multiple tubes are bundled and routed together through the integrated cartridge assembly, with common mounting points and alignment features. This merging of tube management allows all tubes to be installed and tensioned as a group rather than individually, streamlining the production process while ensuring each tube maintains proper tension for effective peristaltic pumping.
3Manufacturing precision
If cartridges are attached individually to the peristaltic pump, then each cartridge can be positioned precisely, but the installation and maintenance process requires multiple sequential steps
Solution Approach 1:
The cartridges are integrated into a single rigid or semi-rigid assembly with a common mounting interface. This integrated structure maintains precise positioning of each cartridge relative to the others while presenting a single attachment interface to the pump. The entire cartridge assembly can be installed or removed in one operation, eliminating the need for multiple sequential attachment steps while preserving the precise positioning required for proper tube routing and pump operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design simplifies the production and installation of dispenser cassettes, reduces production time, and allows for flexible use with various peristaltic pumps, while minimizing tube load and enabling precise medium dosing without additional resistance.
Implementation Method 1
The second cartridges are connected to one another by an elastic connector... Because of the elasticity of the connector, the cartridges can move in relation to one another to a certain extent.
Implementation Method 2
The tubes used in a dispenser cassette must have a flexible outer wall. The medium is conveyed in the tubes through peristalsis.
