Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hydrogen fuel vehicles face vibration and movement issues due to separately mounted fuel cell stacks and accessories, which lack effective insulation and control mechanisms, leading to shaking and reduced driving performance.
Innovation Solution
A mount comprising an inner and outer pipe with insulators to insulate and control the movement of vehicle components, featuring bridge and axial/radial stopping portions to absorb and stop vibrations and movements in multiple directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the fuel cell stack and accessories are mounted separately on the vehicle body, then the mounting flexibility and accessibility are improved, but vibration insulation and movement control are insufficient
Solution Approach 1:
The mount is divided into multiple functional components: an inner pipe coupled to the vehicle body, an outer pipe coupled to the fuel cell stack, and multiple insulators positioned at different locations. This segmentation allows each component to perform a specific function - the insulators selectively insulate vibrations in different directions while the pipe structure provides mounting flexibility and accessibility.
Solution Approach 2:
The insulators act as intermediary elements between the inner pipe (vehicle body) and outer pipe (fuel cell stack). These insulators mediate the vibration transmission by selectively insulating vibrations in specific directions while allowing controlled movement in other directions, thus resolving the contradiction between mounting flexibility and vibration insulation.
2Device complexity
If a single insulator is used to mount the fuel cell stack, then the structure is simple, but it cannot effectively control vibrations and movements in multiple directions
Solution Approach 1:
The insulator system is segmented into multiple insulators positioned at different locations around the outer pipe. Each insulator is responsible for insulating vibrations in specific directions, creating a comprehensive vibration control system that addresses multi-directional vibrations without requiring an overly complex single-structure solution.
Solution Approach 2:
The vibration insulation problem is solved by adding spatial dimensionality - instead of using a single insulator that must handle all directions, multiple insulators are distributed in different spatial positions around the outer pipe. This dimensional approach allows each insulator to specialize in specific directional vibrations while collectively providing comprehensive coverage.
3Object-affected harmful factors
If the insulator structure is made more complex to improve vibration insulation, then vibration control is improved, but manufacturing cost and assembly complexity increase
Solution Approach 1:
The mount is segmented into standardized components (inner pipe, outer pipe, multiple insulators) that can be manufactured independently using conventional processes. This segmentation allows each component to be produced efficiently and assembled in a straightforward sequence, maintaining ease of manufacture while achieving superior vibration insulation through the coordinated arrangement of components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The mount effectively insulates and controls vibrations and movements, improving driving performance by preventing shock transmission and reducing resonance, thus enhancing vehicle stability and travel performance.
Implementation Method 1
a first insulator formed between the inner pipe and the outer pipe. The first insulator is configured to insulate vibration of the vehicle component and to stop a first direction movement of the vehicle component occurring in an axial direction of the inner pipe
Implementation Method 2
a second insulator disposed to be axially spaced apart from the first insulator. The second insulator is configured to stop a second direction movement of the vehicle component occurring in the axial direction of the inner pipe and a movement of the vehicle component occurring in a radial direction of the inner pipe

AI summary
A mount is configured to control and insulate movement and vibration of a vehicle component mounted to a vehicle body. The mount includes an inner pipe coupled to the vehicle body, an outer pipe disposed on an external side of the inner pipe and coupled to the vehicle component mounted to the vehicle body, and a first insulator between the inner pipe and the outer pipe. The first insulator is configured to insulate vibration of the vehicle component and to stop a first direction movement of the vehicle component occurring in an axial direction of the inner pipe. The mount further includes a second insulator disposed to be axially spaced apart from the first insulator. The second insulator is configured to stop a second direction movement of the vehicle component occurring in the axial direction of the inner pipe and a movement of the vehicle component occurring in a radial direction of the inner pipe.
