Vibration-Proof Mount Structure for Lower Weight and Load Dispersion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vibration-proof mounts do not consider reducing weight, which is desirable for manufacturing and transportation costs.
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 from a vibration device to the lower base plate, allowing for reduced thickness and weight, and optionally including a second mounting portion for connected devices with lower load and thinner design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the vibration-proof mount uses a conventional design without considering weight reduction, then the structural strength and load-bearing capacity are maintained, but the weight of the mount increases, leading to higher manufacturing and transportation costs
Solution Approach 1:
The patent applies local quality by making the first mounting portion have higher rigidity than the lower base plate. This localized increase in rigidity at the mounting portion allows the mount to bear loads effectively while the rest of the structure can be optimized for weight reduction, resolving the contradiction between weight reduction and load-bearing capacity
Solution Approach 2:
The patent segments the mounting structure into distinct components with different rigidity requirements - the first mounting portion with higher rigidity and the lower base plate with standard rigidity. This segmentation allows each part to be optimized independently, enabling weight reduction in the lower base plate while maintaining sufficient strength through the rigid mounting portion
2Stability of the object's composition
If the first mounting portion has lower rigidity than the lower base plate, then the structure can be more flexible and lighter, but deformation under load increases, reducing the effectiveness of load dispersion to the lower base plate
Solution Approach 1:
The patent makes the first mounting portion have higher rigidity than the lower base plate, creating a localized rigid zone that controls deformation at the critical load application point. This allows the lower base plate to be thinner and lighter while the rigid mounting portion ensures proper load dispersion occurs without excessive deformation
3Strength
If the lower base plate thickness is increased to improve load distribution, then the load-bearing capacity and stability are enhanced, but the weight of the entire vibration-proof mount increases
Solution Approach 1:
The patent resolves this contradiction by concentrating the rigidity enhancement in the first mounting portion rather than increasing the thickness of the entire lower base plate. This localized approach allows effective load distribution while minimizing the weight increase, as only the critical mounting area requires higher rigidity
Solution Approach 2:
The patent segments the structural requirements by making the first mounting portion thicker or more rigid than the lower base plate. This segmentation allows the lower base plate to maintain adequate load distribution capability with reduced thickness, while the mounting portion provides the necessary rigidity for effective load transfer

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.
