Helicoidal Spring Pump Mount for Beverage Machine Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vibrations from reciprocating piston pumps in beverage preparation machines negatively affect the quality and operational feel of the devices and other components, as existing solutions like suspension with spaced apart suspenders or elastic supports do not adequately address the issue.
Innovation Solution
A beverage preparation machine design that mounts a vibrating pump on a helicoidal dampening spring, which absorbs and reduces vibrations, allowing friction-free movement of the pump and connected components, thereby minimizing vibration transmission to other machine parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the pump is mounted directly in the housing, then the device structure is simple, but vibrations are transmitted to other machine parts affecting quality and operational feel
Solution Approach 1:
A dampener comprising a spring is introduced as an intermediary element between the pump and the housing. The spring absorbs and attenuates vibrations generated by the pump during operation, preventing their transmission to other machine parts while maintaining a relatively simple mounting structure.
Solution Approach 2:
The dampener is pre-installed between the pump mounting surface and the housing to provide vibration cushioning before the pump is mounted. This beforehand cushioning arrangement ensures that vibrations are absorbed at the source without requiring complex post-mounting adjustments or additional vibration isolation components.
2Object-affected harmful factors
If spaced apart suspenders or elastic supports are used to reduce vibrations, then vibration transmission is reduced, but the number of components increases and assembly becomes more complex
Solution Approach 1:
The dampener integrates multiple functions into a single component: it provides vibration isolation, supports the pump weight, and serves as a mounting interface. This merging of functions reduces the number of separate components compared to using multiple suspenders or elastic supports, while achieving effective vibration reduction.
Solution Approach 2:
The spring-based dampener performs multiple roles simultaneously: it acts as a vibration isolator, a structural support element, and a mounting interface for the pump. This multi-functionality eliminates the need for separate vibration isolation components, simplifying the overall device structure.
3Object-affected harmful factors
If multiple components are used for pump mounting and vibration reduction, then vibration isolation is improved, but the number of potential leak points and assembly complexity increases
Solution Approach 1:
The dampener combines vibration isolation functionality with the pump mounting structure into a single integrated component. This reduces the number of separate parts and connection interfaces, thereby minimizing potential leak points and improving overall system reliability.
