Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compressed air supply systems for vehicles lack the speed, flexibility, and efficiency required for quick adjustment of ground clearance, particularly in air spring systems, leading to inefficiencies in pressure medium management and storage.
Innovation Solution
A pressure medium supply system with a two-stage or multi-stage compressor that optimizes the routing of charged pressure medium and additional pressure medium from the first compressor stage to the second stage, utilizing directional valves and a vent valve system to enhance load utilization and storage, allowing for simultaneous supply and regeneration of the system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a conventional single-stage compressor is used, then the device complexity is low, but the speed and flexibility of pressure medium supply are insufficient
Solution Approach 1:
The compressor is divided into multiple stages (first compression stage and second compression stage), with each stage performing partial compression. This segmentation allows the system to achieve higher speeds and flexibility in pressure medium supply while managing complexity through modular design.
Solution Approach 2:
The patent introduces a temporal dimension to the compression process by implementing sequential multi-stage compression. Pressure medium flows through multiple compression stages in sequence, enabling faster and more flexible pressure buildup compared to a single-stage system, while the modular staged architecture manages system complexity.
2Productivity
If pressure medium is stored in a reservoir under high pressure, then the productivity of the pneumatic system is improved, but the loss of energy increases due to pressure maintenance
Solution Approach 1:
The patent implements dynamic pressure management by maintaining different pressure levels in different reservoirs (first reservoir at lower pressure, second reservoir at higher pressure). This parameter variation allows the system to achieve high productivity when needed while reducing energy loss during normal operation by using the lower-pressure reservoir first.
Solution Approach 2:
The system pre-compresses pressure medium to different levels in separate reservoirs in advance. The first compression stage fills the first reservoir, and the second compression stage fills the second reservoir. This preliminary action ensures that high-pressure medium is available when needed for high productivity, while the staged approach optimizes energy usage.
3Use of energy by moving object
If a two-stage compressor with simultaneous routing is used, then the use of energy is optimized, but the device complexity increases
Solution Approach 1:
The charging arrangement is designed with multi-functionality, where the same compression stages and routing infrastructure serve multiple purposes: compressing atmosphere to first reservoir, compressing first reservoir to second reservoir, and providing pressure medium to the pneumatic system. This universality optimizes energy usage by eliminating redundant compression steps while managing complexity through integrated design.
4Reliability
If the compressor runs continuously to maintain high pressure, then the pressure level in the reservoir is maintained, but the loss of time for system response increases
Solution Approach 1:
The system performs preliminary compression actions by filling the first reservoir with the first compression stage and the second reservoir with the second compression stage in advance. This stored high-pressure medium is readily available when needed, ensuring reliable pressure supply without requiring continuous compressor operation, thus reducing response time and energy consumption.
