Vehicle Seat Air Spring Leveling Without Compressor Noise
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seat leveling and stabilization systems rely on compressors, which are loud and slow, making them unsuitable for quiet operation and fast dynamic level regulation.
Innovation Solution
A vehicle seat system with an air spring connected to an additional volume module, where a control unit adjusts the volume of the work volume to change air spring pressure, maintaining a constant distance between the seat top and a reference area without the need for a compressor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a compressor is used to regulate the internal pressure of the air spring, then the level control function is achieved, but the noise level increases and the response speed decreases
Solution Approach 1:
The patent extracts the harmful compressor component from the system and replaces it with a passive additional volume module. The air spring's pressure regulation is achieved by changing the volume of the additional volume module, eliminating the need for an active compressor and thus removing the source of noise and slow response.
Solution Approach 2:
The patent changes the volume parameter of the additional volume module to regulate the air spring's internal pressure. By adjusting the volume of the additional volume module, the system achieves rapid pressure equalization without the delays inherent in compressor operation, while also eliminating compressor noise.
2Stability of the object's composition
If the compressor is activated frequently to maintain constant distance, then the level stabilization is improved, but the noise exposure increases and ear problems may occur
Solution Approach 1:
The patent removes the compressor from the system entirely, replacing it with a passive volume adjustment mechanism. This eliminates the frequent activation of noisy equipment while maintaining stable distance control through volume-based pressure regulation.
Solution Approach 2:
The system uses the additional volume module to automatically regulate air spring pressure through volume changes. The module passively equalizes pressure without requiring active compressor intervention, thereby eliminating frequent noise exposure while maintaining stabilization.
3Stress or pressure
If a compressor is used for fluid supply, then pressure regulation is achieved, but the activation speed is slow and fluid supply is insufficient for rapid control
Solution Approach 1:
The patent extracts the compressor and replaces it with a direct volume adjustment mechanism. The additional volume module can change volume rapidly without the mechanical delays of compressor activation, enabling fast fluid supply for dynamic level control.
Solution Approach 2:
The additional volume module is pre-configured to provide the necessary fluid volume for pressure regulation. When volume adjustment is needed, the system can immediately access the pre-positioned fluid volume without waiting for compressor activation and fluid generation, achieving rapid response.
