Linear Compressor Piston Assembly for Lateral Force Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Linear compressors face issues with lateral force damage to the piston and increased manufacturing complexity due to the need for precise component alignment and support.
Innovation Solution
The compressor design incorporates a piston with a guide portion, a head portion, an intake valve, a fixing member, a rod extending axially, and elastic members connected to the fixing member and rod, which distribute lateral forces and improve rigidity through spacers and fastening members, reducing the complexity of the manufacturing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a piston reciprocates axially in a linear compressor, then compression function is achieved, but lateral force damages the piston
Solution Approach 1:
The patent introduces a guide portion as an intermediary component between the piston and cylinder. This guide portion receives and directs the lateral force that would otherwise damage the piston, allowing the piston to reciprocate axially for compression while protecting it from lateral force damage through the mediating action of the guide structure
2Strength
If precise component alignment and support structures are added to handle lateral forces, then piston protection is improved, but device complexity increases
Solution Approach 1:
The patent merges the guide portion with the piston structure itself, forming an integrated component rather than adding separate support structures. The guide portion is formed as part of the piston assembly, which simplifies the overall device complexity while still providing the necessary lateral force management and piston protection

Function Achieved in This Case
This design effectively distributes lateral forces applied to the piston, enhancing its durability and reducing the manufacturing complexity by simplifying the component assembly process while maintaining the compressor's efficiency.
Implementation Method 1
a first elastic member connected to the fixing member and other side of the rod; a second elastic member disposed to be spaced apart from a rear of the first elastic member and connected to the fixing member and the other side of the rod
