Solution Overview
Problem
Conventional high-pressure gas compressors with moving pistons face challenges in achieving complete sealing and are prone to wear, requiring more installation space and having higher maintenance needs compared to the proposed diaphragm-based compressor system.
Innovation Solution
A high-pressure compressor system utilizing a deformable diaphragm within a pressure container, where the diaphragm compresses gas by deforming against a contour bar, eliminating the need for seals with moving components and allowing for higher compression ratios with reduced material thickness and installation space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional piston compressors are used for high-pressure gas compression, then compression function is achieved, but sealing difficulties and wear problems occur
Solution Approach 1:
The patent extracts the sealing problem from the compression system by eliminating moving seals entirely. The diaphragm compressor separates the compression chamber from the drive mechanism, so the diaphragm itself acts as a seal that deforms to compress gas without requiring seals against moving parts. This resolves the sealing reliability issue by removing the source of sealing failures.
Solution Approach 2:
The diaphragm serves as an intermediary element between the drive mechanism and the gas being compressed. It transmits the compression force while maintaining separation between the moving components and the gas, eliminating the need for seals between moving parts and the compression chamber.
2Productivity
If piston compressors are used, then gas compression is achieved, but more installation space is required
Solution Approach 1:
The patent uses a flexible diaphragm instead of rigid piston structures. The diaphragm can deform elastically to compress gas, allowing for a more compact design. The thin-film diaphragm replaces bulky piston assemblies, reducing the overall footprint while maintaining compression capability.
3Power
If conventional compressors with moving parts are used, then compression is achieved, but higher maintenance needs result
Solution Approach 1:
The patent extracts the wear-prone sealing components from the compression system. By using a diaphragm that deforms without contacting moving parts, the design eliminates the primary sources of wear and maintenance needs while preserving compression power.
Solution Approach 2:
The diaphragm is designed as a simple, replaceable component with no moving parts to wear out. While the diaphragm itself may need periodic replacement, the overall maintenance burden is reduced compared to complex sealing systems in piston compressors.

AI summary
A high-pressure compressor and a system including a high-pressure compressor are described, wherein the high-pressure compressor includes at least one pressure container surrounding at least one media chamber and at least one compressor assembly. A diaphragm separates the at least one media chamber from at least one compressor chamber.
