Beverage Pump Support Assembly for Housing Vibration Damping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Beverage preparation machines experience vibrations from oscillating or rotational movements of pumps, 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 mount the pump within the housing, absorbing vibrations through deformability around multiple flexion axes, and an elastic sealing member is connected to the rigid duct to prevent vibration transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a pump with oscillating or rotational movement is used to promote liquid, then liquid flow is improved, but vibrations are generated and transmitted to the housing
Solution Approach 1:
An elastic support member is introduced as an intermediary element between the pump and the housing. This support member absorbs and dampens vibrations generated by the pump's oscillating or rotational movement, preventing their transmission to the housing while allowing the pump to maintain its liquid-promoting function.
Solution Approach 2:
The physical state of the support structure is changed from rigid to elastic. By using an elastic support member with appropriate material properties (viscoelasticity, damping characteristics), the system transforms the way vibrations are handled, converting harmful vibrational energy into heat through internal friction within the elastic material.
2Stability of the object's composition
If the pump is rigidly mounted to the housing, then structural stability is improved, but vibrations are transmitted to the housing and other components
Solution Approach 1:
The rigid support structure is replaced with an elastic support member that exhibits flexible mechanical behavior. This elastic element can deform under vibrational loads, absorbing energy through elastic deformation and viscous damping, thereby maintaining structural stability while preventing vibration transmission.
Solution Approach 2:
The support member is made from composite or viscoelastic materials that combine rigidity for structural support with damping properties for vibration absorption. These materials exhibit both elastic solid and viscous fluid characteristics, allowing them to maintain structural integrity while dissipating vibrational energy.
3Object-generated harmful factors
If vibrations are reduced by isolating the pump, then vibration transmission is improved, but pump movement flexibility may be reduced
Solution Approach 1:
The support system transitions from a static rigid connection to a dynamic elastic connection. The elastic support member can adapt its stiffness and damping characteristics based on the operating conditions, allowing sufficient pump movement flexibility for liquid promotion while effectively isolating vibrations at different frequencies and amplitudes.
