Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of supporting an electric compressor in electric vehicles without an integrated engine, which leads to increased vibration and noise, compromising vehicle comfort.
Innovation Solution
A supporting structure that utilizes elastic members, with the first elastic member positioned below the compressor's center of gravity and the second elastic member positioned away from the compression mechanism side, effectively reducing vibration input to the vehicle body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If an electric compressor is used in electric vehicles without an integrated engine, then the vehicle can achieve sustainable transportation and improved fuel efficiency, but vibration and noise increase, compromising vehicle comfort
Solution Approach 1:
The supporting structure divides the compression mechanism into separate components with independent elastic members, allowing each part to be optimized for vibration reduction while maintaining compression function
Solution Approach 2:
Elastic members are introduced as intermediary elements between the compression mechanism and the vehicle body, serving as vibration isolation mediators that decouple the harmful vibrations from the compressor while maintaining structural support
2Adaptability or versatility
If the compression mechanism is separated from the engine structure, then the electric compressor can be independently installed, but a separate supporting structure is required, increasing device complexity
Solution Approach 1:
The elastic members serve multiple functions simultaneously: they provide mechanical support for the compression mechanism, isolate vibrations, and allow for adjustable positioning, reducing the need for additional dedicated components
Solution Approach 2:
The supporting structure uses elastic members that can dynamically adapt to vibration frequencies and loads, providing flexible support that adjusts to operating conditions rather than requiring rigid, complex mounting structures
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 described supporting structure significantly reduces vibration and noise from the compressor, enhancing vehicle comfort and contributing to the development of sustainable transportation systems.
Implementation Method 1
The first elastic member is disposed below the center of gravity in an up-down direction
Implementation Method 2
the second elastic member uses the lever principle to suppress the vibration (larger vibration) on the other end of the compression mechanism side
Implementation Method 3
The supporting structure includes elastic members. The elastic members include a first elastic member and a second elastic member

AI summary
A supporting structure that may reduce the vibration of the compressor input to the vehicle body is provided in the disclosure. The supporting structure is used to support a compressor that compresses gas, and includes elastic members. The elastic members include a first elastic member and a second elastic member. A center of gravity of the compressor is set between the first elastic member and the second elastic member, and the first elastic member is disposed below the center of gravity in an up-and-down direction. The second elastic member is farther away from a compression mechanism side of the compressor than the first elastic member.
