Suspension-Mounted Piping Fixing for Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing piping fixing structures for radiator hoses, which involve fixing the hoses to a radiator core support via an elastic body to absorb vibrations, increase manufacturing costs and can lead to vibration transmission to the vehicle body, affecting ride comfort.
Innovation Solution
A piping fixing structure that uses a suspension member elastically supported by the vehicle body via a first vibration damping member, which supports the suspension and fixes the piping, extending from a driving source, using a second vibration damping member to prevent vibration transmission without additional parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a radiator hose is fixed to a radiator core support via an elastic body to absorb vibration, then vibration interference with peripheral parts is prevented, but manufacturing cost increases due to additional parts
Solution Approach 1:
The patent merges the piping fixing function with the suspension member by integrating the fixing mechanism directly into the suspension member structure. The suspension member serves dual purposes: supporting the suspension system and fixing the piping, thereby eliminating the need for separate elastic bodies or additional fixing components while still providing vibration absorption through the inherent elasticity of the suspension member.
Solution Approach 2:
The suspension member is designed to perform multiple functions simultaneously: it acts as both a suspension support structure and a piping fixing mechanism. This multi-functional design allows the piping to be secured without requiring dedicated elastic bodies or separate mounting components, reducing part count while maintaining vibration isolation capabilities.
2Object-affected harmful factors
If a radiator hose is fixed to a radiator core support, then vibration interference with peripheral parts is prevented, but vibration travels to the vehicle body causing deterioration of ride comfort
Solution Approach 1:
The suspension member acts as an intermediary element between the piping and the vehicle body. It provides a flexible mounting point that secures the piping while its elastic properties allow it to absorb and isolate vibrations, preventing them from being transmitted to the rigid vehicle body structure. The suspension member mediates between the need for secure fixation and the need for vibration isolation.
3Object-affected harmful factors
If space is provided around a radiator hose to avoid vibration interference, then peripheral part interference is prevented, but effective use of space is reduced
Solution Approach 1:
The patent transitions from a static space-provision approach to a dynamic fixation approach. Instead of allocating fixed space around the piping to accommodate vibrations, the suspension member provides dynamic support that allows the piping to move with the suspension movements while maintaining secure attachment. This enables tighter space arrangement without risking peripheral part interference.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution effectively absorbs vibrations at the suspension member, preventing them from reaching the vehicle body, thus enhancing ride comfort without adding extra components, and simplifies the attachment process, reducing manufacturing costs.
Implementation Method 1
