Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large compressor or complex apparatus is used to refill the pressure chamber, then the pressure chamber can be refilled to maintain predetermined pressure, but the device complexity and equipment size increase
Solution Approach 1:
The patent makes the pressure chamber volume adjustable through a movable partition wall that can be positioned at different levels. This dynamic adjustment allows the system to maintain predetermined pressure with a simpler refilling apparatus, as the volume can be adapted to match the refilling capability of smaller compressors or pumps.
Solution Approach 2:
The system changes the physical parameter of pressure chamber volume to enable refilling with simpler equipment. By adjusting the volume parameter, the predetermined pressure can be achieved even when using smaller, less complex refilling apparatus, thus resolving the contradiction between pressure maintenance reliability and device complexity.
2Adaptability or versatility
If the pressure chamber volume is fixed, then the structure is simple, but the ability to adjust pressure settings is limited
Solution Approach 1:
The partition wall is designed to be movable rather than fixed, allowing the pressure chamber volume to be dynamically adjusted. This enables different pressure settings while adding minimal structural complexity, as the partition wall can be guided along predetermined paths or positions within the chamber.
Solution Approach 2:
The pressure chamber is segmented into adjustable sections by the movable partition wall. This segmentation allows independent adjustment of volume while maintaining a relatively simple overall structure, enabling versatile pressure settings without requiring a completely complex redesign of the chamber.
3Loss of energy
If a small simple compressor is used for refilling, then the equipment size is reduced, but the ability to reach predetermined pressure levels is compromised
Solution Approach 1:
By changing the volume parameter of the pressure chamber through movable partition walls, the system enables smaller compressors to achieve the same pressure levels. The reduced volume allows smaller equipment to generate sufficient pressure, thus reducing equipment size while maintaining pressure level achievement capability.
Solution Approach 2:
The dynamic adjustment of chamber volume allows the system to optimize the pressure generation process for smaller compressors. By adjusting the volume to match the capabilities of compact refilling equipment, the system achieves predetermined pressure levels effectively while minimizing equipment size and energy loss.
