Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If standard piston compressors and pumps are used to achieve high pressure, then pressure is improved, but device complexity and manufacturing cost increase significantly
Solution Approach 1:
The piston is segmented into multiple working surfaces (first, second, third, and fourth working surfaces) that interact with different chambers formed by partition walls. This segmentation allows the single piston to perform multiple functions simultaneously, achieving high pressure through coordinated action of multiple chambers rather than requiring complex multi-stage compression systems.
Solution Approach 2:
The single piston serves multiple functions by having different working surfaces that compress different fluids in different chambers. The first piston surface compresses fluid in the first chamber, while the second piston surface compresses fluid in the second chamber, allowing one component to replace what would traditionally require multiple separate compression mechanisms.
2Force
If conventional lubrication systems are implemented to reduce friction, then friction is reduced, but device complexity increases
Solution Approach 1:
The invention uses hydraulic principles by introducing a hydraulic film through the third working surface and third chamber. This hydraulic film acts as a lubricant between the piston and fourth partition wall, reducing friction without requiring complex mechanical lubrication systems. The hydraulic pressure itself creates the lubricating effect.
3Stress or pressure
If multiple working circuits are used in pumps to achieve high pressure, then pressure is improved, but device weight and manufacturing cost increase
Solution Approach 1:
Multiple compression circuits are merged into a single piston structure. The first and second chambers with their respective partition walls are integrated around a single piston, allowing simultaneous compression in multiple chambers without requiring separate pump units. This merging reduces overall device weight while maintaining high pressure capability.
4Adaptability or versatility
If rotary pistons operate with high clearance to handle fluids with impurities, then adaptability is improved, but sealing efficiency deteriorates
Solution Approach 1:
The invention introduces intermediate hydraulic chambers and hydraulic films as mediators between the piston and partition walls. The third chamber with its hydraulic film acts as an intermediary that maintains sealing efficiency even when clearances are increased to accommodate impurities. The hydraulic pressure in this intermediate chamber ensures continuous contact and sealing.
