Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pump devices lack a compact design with easy component replacement and efficient fluid delivery, particularly in sterile or high-sterility environments, where defective components need quick replacement without fluid loss.
Innovation Solution
A pump device with a spring-elastic conveying element that forms an interchangeable unit with the conveying space element, allowing for easy replacement and minimizing fluid loss, featuring a drive unit with a movably mounted force-acting element that encircles the conveying space to facilitate fluid conveyance through a circular ring configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the conveying device uses a rigid conveying chamber element and elastically deformable conveying element design, then the device achieves compact structure and efficient fluid delivery, but component replacement becomes complex and time-consuming
Solution Approach 1:
The conveying device is divided into modular components: a conveying chamber element and a conveying element that can be separated and replaced independently. This segmentation allows the conveying element to be quickly exchanged without replacing the entire conveying device, maintaining high productivity while enabling easy repair.
Solution Approach 2:
The conveying element is designed as an elastically deformable component that can dynamically change shape during operation to efficiently convey fluid, while its modular design allows static replacement when needed. This dynamic flexibility during operation combined with easy replaceability resolves the contradiction between productivity and ease of repair.
2Productivity
If the conveying element is designed to be elastically deformable for efficient fluid conveyance, then conveying capacity is improved, but the element cannot maintain sterile conditions and requires frequent replacement
Solution Approach 1:
The conveying element is separated as a replaceable module from the conveying chamber element. This allows the conveying element to be designed for elastic deformation (maintaining conveying capacity) while enabling its complete removal and replacement when sterility is compromised, thus maintaining reliability through easy exchange of the deformable component.
Solution Approach 2:
The conveying element can be designed as a disposable or limited-life component that maintains sterile conditions during its service life. When sterility is compromised or the element wears out, it is replaced rather than sterilized or repaired, ensuring reliability while allowing the element to be optimized for elastic deformation and conveying capacity.
3Volume of moving object
If the conveying device uses a compact design with encircling drive element, then device size is reduced, but component accessibility for replacement becomes difficult
Solution Approach 1:
The conveying device is segmented into a conveying chamber element and a conveying element with different accessibility requirements. The conveying chamber element can be designed as a compact, encircling structure, while the conveying element is designed as a separable module that can be accessed and replaced without disassembling the entire compact structure, resolving the contradiction between compact size and repair accessibility.
