Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional anti-vibration support structures for onboard devices require multiple suspension bolts and complex assembly processes due to the use of elastic members like anti-vibration rubber, resulting in a complicated structure.
Innovation Solution
An anti-vibration support structure comprising a first and second support, a target support, and first and second elastic members, where the target support is retained between the supports via the elastic members without the need for fastening members like bolts, simplifying the structure and assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If suspension bolts are used to fix the underfloor device to the floor structure, then the anti-vibration support structure can be assembled, but the structure becomes complicated and the assembly process becomes complicated
Solution Approach 1:
The patent removes the suspension bolts from the support structure, retaining only the elastic member (anti-vibration rubber) to perform both the support and anti-vibration functions. This extraction of unnecessary fastening components directly reduces structural complexity while maintaining anti-vibration performance through the elastic member's inherent properties.
Solution Approach 2:
The elastic member is designed to simultaneously perform multiple functions: supporting the underfloor device, providing anti-vibration performance, and eliminating the need for separate fastening mechanisms. This multi-functionality consolidates the structure, reducing the number of components and simplifying assembly while maintaining reliability.
2Reliability
If suspension bolts are used to fix the underfloor device, then the device can be securely mounted, but the assembly process becomes complicated
Solution Approach 1:
By removing the suspension bolts entirely and relying on the elastic member's elastic force and friction to secure the underfloor device, the assembly process is simplified to a single insertion motion without requiring threading, tightening, or multiple fastening steps, thereby improving ease of operation while maintaining mounting security.
Solution Approach 2:
The elastic member automatically secures the underfloor device through its elastic force and friction, without requiring external fastening actions. The structure self-secures upon installation, eliminating the need for complex assembly operations involving bolts and fasteners.
3Strength
If multiple suspension bolts are used, then the underfloor device can be firmly supported, but the structure becomes complicated
Solution Approach 1:
The elastic member is designed with sufficient elastic force and friction characteristics to simultaneously provide firm support and secure mounting functions that would traditionally require multiple bolts. This single-component solution maintains support strength while eliminating the complexity of multiple fastening elements.
Solution Approach 2:
The elastic member utilizes composite material properties (elasticity and friction) to achieve both support strength and secure mounting in a single component, replacing multiple rigid bolt connections with a flexible yet strong elastic element that adapts to the mounting requirements.

Implementation Method 1
The anti-vibration support structure for an onboard device includes a first elastic member and a second elastic member. The target support is supported by being retained between the first support and the second support at least via the first elastic member and the second elastic member.

AI summary
In an anti-vibration support structure for an onboard device (100), a first support (110) is located under the floor of a vehicle (10) and is fixed to the vehicle (10). A second support (120) is located under the floor of the vehicle (10) and is fixed to the vehicle (10). The second support (120) is located above the first support (110) while being apart from the first support (110). A target support (130) is fixed to an onboard device (20). The target support (130) is located at least in part between the first support (110) and the second support (120) so as not to be in contact with the first support (110) and the second support (120). The target support (130) is supported by being retained between the first support (110) and the second support (120) at least via a first elastic member (140) a second elastic member (150).
