Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing reciprocating compressors face limitations in frequency usage due to self-resonance in coil springs, mechanical stress, vibration distance, and complex device structures, which restrict compressor efficiency and size reduction.
Innovation Solution
The use of an electromagnetic resonance spring, generated by a magnet and stator core interaction, allows for resonant motion of the piston, overcoming frequency limitations and simplifying the compressor structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a coil spring is used as a resonance spring, then the piston can be supported elastically, but the frequency usage is limited due to self-resonance in the coil spring
Solution Approach 1:
The patent replaces the mechanical coil spring with an electromagnetic resonance spring that uses electromagnetic fields instead of mechanical elasticity. The electromagnetic resonance spring comprises a coil and a magnet that generate electromagnetic forces to provide the resonant support for the piston, eliminating the self-resonance limitations of mechanical springs and expanding the usable frequency range.
2Stability of the object's composition
If resonance springs are installed at both sides of the piston, then the piston can be properly supported, but the device structure becomes complex
Solution Approach 1:
The patent merges the functions of multiple resonance springs into a single electromagnetic resonance spring assembly. The electromagnetic resonance spring integrates both sides of support functionality through the interaction between the coil and magnet, eliminating the need for separate springs at each side of the piston and simplifying the overall device structure.
3Stability of the object's composition
If compression coil springs are used, then the piston can be elastically supported, but the horizontal length of the compressor increases
Solution Approach 1:
The patent replaces the mechanical compression coil spring with an electromagnetic resonance spring that provides elastic support through electromagnetic forces. This substitution eliminates the need for physical coil spring components that occupy horizontal space, thereby reducing the overall horizontal length of the compressor while maintaining piston support stability.
