Lightweight Vibration-Proof Mount With Segmented Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vibration-proof mounts do not consider reducing manufacturing and transportation costs by minimizing weight, leading to a need for a lighter weight solution.
Innovation Solution
A vibration-proof mount design with an upper base plate and a lower base plate connected by multiple first connecting members, where the first mounting portion has higher rigidity than the lower base plate, dispersing the load and allowing for reduced thickness and weight, and optionally incorporating a second mounting portion with a connecting portion and a separating or linking member to further reduce weight and prevent vibration transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the vibration-proof mount is made with conventional design, then the structural strength is sufficient, but the weight is excessive
Solution Approach 1:
The patent applies different rigidity levels to different parts of the mounting portion: the first mounting portion has higher rigidity to support the vibration device, while the second mounting portion has lower rigidity to reduce weight. This local differentiation allows the structure to be strong where needed and light where not required, resolving the contradiction between overall strength and weight reduction.
Solution Approach 2:
The mounting portion is divided into multiple segments (first mounting portion and second mounting portion) with different rigidity characteristics. This segmentation allows each part to be optimized independently - the first portion maintains high strength for vibration support while the second portion reduces weight, thereby resolving the contradiction between structural strength and weight.
2Force
If the first mounting portion has higher rigidity than the lower base plate, then the load is dispersed more effectively, but the manufacturing complexity increases
Solution Approach 1:
The patent implements local quality by making only the first mounting portion (the region directly supporting the vibration device) have higher rigidity than the lower base plate, while other portions maintain lower rigidity. This localized approach to rigidity enhancement minimizes the additional manufacturing complexity while maximizing load dispersion effectiveness at the critical support point.

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.
