Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Beverage preparation machines, such as those with circulating pumps, generate vibrations that lead to noise and nuisance, which existing solutions like resilient mounts and controlled pumping do not fully address.
Innovation Solution
A vibration-barrier mechanical connection between the beverage preparation module and the liquid reservoir, using an elastic interface and a resilient section in the fluid circulation line to prevent vibration propagation, along with a disconnectable reservoir and vibration-dampening components like rubber feet, to isolate the reservoir from vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a pump is used to circulate liquid through the beverage preparation machine, then liquid circulation is achieved, but vibrations and noise are generated
Solution Approach 1:
The patent introduces resilient elements as intermediary components between the pump and the machine structure. These resilient elements act as mediators that allow the pump to function while absorbing and isolating the vibrations it generates, preventing their transmission to the overall machine structure and reducing noise.
Solution Approach 2:
The patent employs flexible resilient elements and dampening materials that can deform elastically to absorb vibration energy. These flexible components are integrated into the machine structure to create vibration isolation zones that protect rigid parts from vibrational stress and noise generation.
2Object-generated harmful factors
If resilient mounts are used for the pump, then vibrations are dampened in the machine, but the complexity of the mounting system increases
Solution Approach 1:
The patent combines multiple functions into integrated mounting structures that simultaneously provide mechanical support, vibration damping, and structural connection. By merging these functions into unified components rather than separate elements, the system achieves effective vibration isolation without proportionally increasing complexity.
Solution Approach 2:
The patent utilizes composite mounting structures that combine rigid and resilient materials with complementary properties. These composite elements provide both the structural strength needed for support and the elastic properties required for vibration damping, achieving multiple objectives with unified components.
3Object-generated harmful factors
If resilient feet are applied underneath the machine, then vibrations are dampened and less propagated to the surface, but the stability of the machine during operation may be compromised
Solution Approach 1:
The patent employs resilient feet with controlled elasticity that provide dynamic response to vibrations. These feet are designed to be sufficiently compliant to dampen high-frequency vibrations and noise propagation to the supporting surface, while maintaining adequate rigidity and friction to ensure operational stability during beverage preparation.

AI summary
A beverage preparation machine (1) comprises: a beverage preparation module (2) that vibrates during use, in particular a module for preparing a beverage by circulating a liquid via a flavoring ingredient such a pre-portioned ingredient contained in a capsule; and a reservoir (4) for storing liquid and supplying such liquid to the beverage preparation module. The beverage preparation module and the reservoir are connected by a vibration-barrier mechanical connection (3, 45, 291, 431) for inhibiting or preventing propagation of vibrations from the beverage preparation module to the reservoir.
