Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional compressors experience unstable piston motion and vibration due to eccentric loading of resonant springs, leading to reduced capability and reliability.
Innovation Solution
The compressor design positions the centers of multiple resonant springs on the same circumference to ensure uniform loading, stabilizing the piston motion and preventing eccentric rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the resonant springs are positioned with different radii from the piston center, then the spring structure can be simplified, but the piston experiences eccentric loading causing unstable motion and vibration
Solution Approach 1:
The patent applies asymmetry in reverse - it establishes symmetry by positioning all resonant spring centers at the same radius from the piston center. This symmetric arrangement ensures that the springs are evenly distributed around the piston, creating balanced forces that prevent eccentric loading and stabilize piston motion, thereby resolving the reliability issue while maintaining reasonable structural complexity
2Ease of manufacture
If the resonant springs are positioned with different radii from the piston center, then the installation process is simplified, but noise and vibration increase due to eccentric rotation
Solution Approach 1:
The patent uses symmetric positioning of resonant spring centers at the same radius to create balanced force distribution. This symmetry prevents eccentric rotation of the piston, thereby reducing noise and vibration harmful factors while maintaining a straightforward installation process
3Device complexity
If the resonant springs are positioned with different radii from the piston center, then the structural design is simplified, but component abrasion increases due to unstable piston motion
Solution Approach 1:
The patent establishes symmetric positioning of resonant spring centers at the same radius from the piston center. This creates balanced loading conditions that stabilize piston motion, preventing excessive wear and abrasion of components while maintaining reasonable structural design complexity
