Beverage Pump Elastic Mounting for Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vibrations from pumps in beverage preparation machines are transmitted to the housing, affecting the quality and operational feel of the device and other components.
Innovation Solution
An elastic support member, such as a bellow-shaped or leaf spring, is used to mount the pump within the housing, absorbing vibrations and preventing their transmission to the housing. This support member allows movement in multiple degrees of freedom and can include electric connection means for a space-saving and automatic assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pump is rigidly mounted to the housing, then the pump is stable and secure, but vibrations are transmitted to the housing affecting quality and operational feel
Solution Approach 1:
An elastic support member is introduced as an intermediary element between the pump and the housing. This mediator absorbs vibrations through its elastic properties while maintaining the pump's stable mounting, thus resolving the contradiction between stability and vibration transmission.
Solution Approach 2:
The support member's elasticity parameter is utilized to change the mechanical coupling characteristics between the pump and housing. By using an elastic rather than rigid connection, the system maintains stability while reducing vibration transmission to acceptable levels.
2Object-affected harmful factors
If an elastic support member is used to reduce vibrations, then vibration transmission is reduced, but the pump mounting complexity increases
Solution Approach 1:
The electric connection means are merged with the elastic support member, integrating two functions (mechanical support and electrical connection) into a single component. This reduces overall mounting complexity while maintaining vibration reduction benefits.
Solution Approach 2:
The elastic support member is designed to perform multiple functions: mechanical support, vibration absorption, and electrical connection. This multi-functionality reduces the need for separate components, thereby simplifying the overall mounting structure despite the added complexity of the elastic element.
3Object-affected harmful factors
If the elastic support member allows movement in multiple degrees of freedom, then vibration absorption is improved, but the precision of pump positioning decreases
Solution Approach 1:
The support member transitions from a static rigid connection to a dynamic elastic connection that allows controlled movement. This dynamic capability enables vibration absorption in multiple degrees of freedom while the elastic properties maintain sufficient positioning precision for 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 elastic support member effectively dampens and absorbs vibrations, enhancing the absorption of axial, lateral, and rotational movements, thereby reducing the transmission of vibrations to the housing and improving the operational stability and efficiency of the pump.
Implementation Method 1
a pump support connected to the housing of the device at which the pump is mounted, in particular comprising an elastic support member, in particular one or more leaf springs or a bellow-shaped elastic support member, for resiliently supporting the pump
Implementation Method 2
The elastic support member can be arranged to be deformable around a plurality of flexion axes to absorb vibrations from the vibrating pump chamber
