Elastic Pump Mounting for Beverage Machine Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Beverage preparation machines experience vibrations from the pump, which 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 resiliently 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 incorporate electric connection means for a space-saving and automatic assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pump is rigidly mounted in the housing, then the pump is stable and secure, but vibrations are transmitted to the housing affecting quality and operational feel
Solution Approach 1:
The patent introduces an elastic support member as an intermediary element between the pump and the housing. This elastic member acts as a mediator that connects the pump to the housing while simultaneously absorbing vibrations, thus preventing vibration transmission to the housing while maintaining pump stability and security.
Solution Approach 2:
The patent changes the mechanical properties of the support structure from rigid to elastic. By using an elastic support member instead of a rigid mounting, the system transforms the support characteristics to allow vibration absorption while maintaining structural integrity and pump stability.
2Reliability
If the pump is rigidly mounted in the housing, then the pump is stable and secure, but other components housed within the housing are negatively affected by vibrations
Solution Approach 1:
The elastic support member serves as an intermediary that isolates the pump's vibrations from other components within the housing. By positioning this elastic element between the pump and the housing structure, it absorbs and dampens vibrations before they can propagate to other sensitive components housed within the same enclosure.
Solution Approach 2:
The support structure's mechanical parameters are changed from rigid to elastic properties. This transformation enables the support to absorb vibrational energy through elastic deformation, thereby protecting other components within the housing from harmful vibrations while maintaining pump stability.
3Object-affected harmful factors
If an elastic support member is used to reduce vibrations, then vibration transmission is prevented, but the pump may become less stable
Solution Approach 1:
The patent optimizes the elastic properties of the support member to achieve a balance between vibration absorption and pump stability. By carefully selecting the elasticity parameters of the support member, the system achieves sufficient vibration isolation while maintaining adequate mechanical support and stability for the pump during operation.
