System having an object supported by a vibration damping mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suspension systems for vibrating components, such as motors in household appliances, often fail to provide sufficient mechanical decoupling and stabilization, leading to misalignment, instability, and excessive vibration transmission due to neglecting the six degrees of freedom of movement.
Innovation Solution
A mounting system using a set of at least three springs, with top and bottom ends defining upper and lower polygons, where the center of gravity aligns with the lower polygon, and the springs are angled inwardly to provide a stabilization surface, reducing the need for additional supports and enhancing stability through a pendulum effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple rubber suspension component or single spring is used, then the device complexity is reduced, but the mechanical decoupling and stabilization performance is insufficient
Solution Approach 1:
The mounting system is segmented into multiple independent spring elements (at least three springs) arranged in a specific geometric configuration. Each spring handles specific degrees of freedom, providing comprehensive vibration isolation while maintaining manageable system complexity through modular arrangement
Solution Approach 2:
The invention transitions from simple vertical suspension to a three-dimensional geometric arrangement where springs are offset from the vertical axis. This angular configuration adds horizontal stabilization capability while maintaining vertical load support, addressing multiple degrees of freedom simultaneously
2Stability of the object's composition
If multiple springs are added to prevent rotation and improve alignment, then the stabilization performance is improved, but the device complexity and part count increase
Solution Approach 1:
The mounting system merges vertical load support and horizontal stabilization functions into a single integrated spring arrangement. The angularly offset springs simultaneously provide both functions, eliminating the need for separate vertical and horizontal suspension components
Solution Approach 2:
Each spring in the arrangement serves multiple functions: supporting vertical load, preventing rotation, and providing horizontal alignment. This multi-functionality reduces the overall number of components needed compared to dedicated single-function mounts
3Ease of operation
If an object is placed on top of springs, then the installation is simple, but the alignment is more complicated and requires more springs
Solution Approach 1:
The springs are pre-configured in a specific angular geometric arrangement with offset mounting points before the object is installed. This preliminary configuration ensures that the object automatically achieves proper alignment when placed on the springs, eliminating complex post-installation adjustment
4Ease of manufacture
If the center of mass is not aligned with spring mounting points, then the object can be easily mounted, but the object will rotate and cause misalignment
Solution Approach 1:
The spring mounting points are deliberately positioned asymmetrically relative to the object's center of mass, with springs offset from the vertical axis. This asymmetric arrangement creates inherent stabilizing moments that automatically correct misalignment and prevent rotation during operation

AI summary
An object is mounted within a housing of a coffee machine by a mounting which is to provide vibration damping for the object. The mounting includes a set of at least three springs, each having a top end coupled to the housing and a suspended bottom end at which the object is supported. The top ends define an upper polygon and the bottom ends define a lower polygon. A center of gravity of the object is along a vertical line which passes through the lower polygon, and springs are angled inwardly towards the lower polygon.
