Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Linear compressors face challenges with vibration and noise due to complex support systems, which increase manufacturing costs, reduce productivity, and lead to defects during assembly, while also providing inadequate damping performance.
Innovation Solution
A simplified supporting damper system for linear compressors, featuring a shell with a support part and a damper that extends inwardly to provide multiple contact points along the shell's inner surface, reducing vibration and noise through a more stable and efficient design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If multiple components (bolts, washers, rubber) are used to support the plate spring, then the supporting stability is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent merges the functions of multiple separate components (bolts, washers, rubber buffers) into a single integrated plate spring structure. The plate spring simultaneously provides mechanical support, vibration damping, and structural connection, eliminating the need for separate supporting components while maintaining stability.
Solution Approach 2:
The plate spring is designed to perform multiple functions: it supports the compressor body, dampens vibrations, reduces noise, and provides structural connection between components. This multi-functional design replaces what would traditionally require several specialized components.
2Stability of the object's composition
If multiple components are provided to support the plate spring, then the supporting stability is improved, but the productivity decreases due to increased assembly complexity
Solution Approach 1:
By combining multiple supporting functions into a single plate spring component, the assembly process is simplified. Instead of requiring multiple separate parts to be assembled, only one component needs to be installed, significantly improving assembly efficiency and productivity.
3Stability of the object's composition
If multiple components are used for supporting the plate spring, then the supporting stability is improved, but the manufacturing cost increases
Solution Approach 1:
The patent consolidates multiple components into a single plate spring, reducing the total number of parts that need to be manufactured, stored, and assembled. This consolidation directly reduces manufacturing costs while maintaining the required supporting stability.
4Stability of the object's composition
If multiple components are provided for supporting the plate spring, then the supporting stability is improved, but the reliability decreases due to increased defect possibility
Solution Approach 1:
By reducing the number of separate components to just the plate spring, the patent minimizes the opportunities for assembly defects. Fewer parts mean fewer potential failure points and simpler assembly processes, thereby improving reliability.
5Device complexity
If plate spring support is used for the compressor body, then the structure is simplified, but the damping performance is insufficient
Solution Approach 1:
The patent modifies the physical parameters of the plate spring (such as material properties, thickness, shape, and configuration) to enhance its damping capabilities. By optimizing these parameters, the plate spring achieves superior vibration and noise reduction performance while maintaining structural simplicity.

Implementation Method 1
a supporting damper that extends from the support part toward an inner surface of the shell
Implementation Method 2
The permanent magnet may be driven to linearly reciprocate by electromagnetic force between the permanent magnet and the inner (or outer) stator

AI summary
A linear compressor includes a shell having a first opening and a second opening defined at opposite ends of the shell, a compressor body including a cylinder and a piston accommodated in the shell, a support part that protrudes from an end portion of the compressor body toward the second opening, a supporting damper that extends from the support part toward an inner surface of the shell. The supporting damper includes a first portion that is coupled to the support part and that defines a single contact region between the support part and the supporting damper, and at least two second portions that extend from the first portion to the inner surface of the shell and that define at least two contact regions that are spaced apart from each other along the inner surface of the shell.
