Vibration-Proof Mount Layout With Rigid Mounting Zone
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vibration-proof mounts are not designed to reduce manufacturing and transportation costs, specifically in terms of weight, leading to a need for a lighter alternative.
Innovation Solution
A vibration-proof mount configuration with an upper base plate having a first mounting portion of higher rigidity than a lower base plate, connected by multiple first connecting members that disperse the load, allowing for reduced thickness and weight, and optionally including a second thinner mounting portion for connected devices with a separating or linking mechanism to manage vibrations and loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the thickness of the lower base plate is increased to reduce deformation, then the structural strength is improved, but the weight of the vibration-proof mount increases
Solution Approach 1:
The first mounting portion is configured with higher rigidity than the lower base plate, creating a local quality differentiation. This allows the mounting portion to have the necessary structural strength while the overall mount can be designed with reduced weight by not uniformly increasing thickness throughout the entire structure.
2Reliability
If the first mounting portion is configured with higher rigidity, then the load application to the lower base plate is improved, but the manufacturing complexity increases
Solution Approach 1:
The first mounting portion is configured with higher rigidity than the lower base plate, creating a local quality differentiation. This allows the mounting portion to have the necessary structural strength while the overall mount can be designed with reduced weight by not uniformly increasing thickness throughout the entire structure.
3Reliability
If multiple first connecting members are disposed at intervals, then the load dispersion is improved, but the device complexity increases
Solution Approach 1:
The connection between the upper and lower base plates is segmented into multiple first connecting members disposed at intervals. This segmentation allows the load to be dispersed across multiple connection points, improving reliability while the modular nature of the connecting members keeps manufacturing relatively simple.

AI summary
A vibration-proof mount which is interposed between a vibration device including a vibration source and an elastic member disposed on a foundation surface includes an upper base plate including a first mounting portion where the vibration device is mounted, a lower base pate arranged below the upper base plate and supporting the upper base plate, and a plurality of connecting members connecting the upper base plate and the lower base plate, the plurality of connecting members including at least two or more first connecting members disposed between the first mounting portion and the lower base plate at intervals from one another. The first mounting portion is configured to have higher rigidity than the lower base plate.
