Gas Compressor Fastening Structure for Stable Tool-Free Storage Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas compressors face challenges in stabilizing the mechanical connection between the auxiliary storage unit and the compressor, especially when attachment is tool-free, leading to instability and difficulty in detachable integration.
Innovation Solution
A gas compressor design featuring a fastening unit that elastically deforms a connecting buffer portion to stabilize the position of the auxiliary storage unit, using a detachable fastening mechanism that applies force to elastically deform the buffer, ensuring stable mechanical connection without tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the auxiliary storage unit is attached to the gas compressor without using a tool such as a driver, then the ease of operation is improved, but the reliability of the mechanical connection deteriorates
Solution Approach 1:
The fastening mechanism is divided into multiple independent fastening members (first and second fastening members) that separately engage with corresponding engagement portions on the auxiliary storage unit and main body portion, allowing tool-free attachment while distributing the connection load across multiple points to maintain reliability
Solution Approach 2:
Connection portions with elastic connectors act as intermediaries between the fastening members and the main body portion/auxiliary storage unit. The elastic connectors provide flexible mechanical engagement that maintains stable connection without requiring tools, bridging the gap between ease of operation and connection reliability
2Reliability
If the auxiliary storage unit is integrated with the gas compressor by screw connection, then the reliability of the mechanical connection is improved, but the device complexity increases due to requiring a driver
Solution Approach 1:
The driver tool is extracted from the fastening process entirely. Instead of using screws that require a driver, the invention employs snap-fit fastening members with elastic connectors that can be attached and detached by hand, eliminating the need for external tools while maintaining connection stability
Solution Approach 2:
The fastening mechanism is designed to be self-sufficient without requiring external tools. The elastic connectors automatically engage with the engagement portions when the fastening members are inserted, and the mechanism can be detached by simply releasing the fastening members, making the entire fastening process self-serviceable
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design allows easy attachment and detachment of the auxiliary storage unit while maintaining a stable mechanical connection, preventing unintentional disengagement and ensuring consistent positioning through the reaction force of the elastic buffer.
Implementation Method 1
The leg portion includes an elastic connecting buffer portion configured to be brought into contact with the support portion, and the fastening unit fastens the auxiliary storage unit by applying a force in a direction in which the first connecting buffer portion is elastically deformed
Implementation Method 2
the position of the gas compressor with respect to the auxiliary storage unit is stabilized by a reaction force of the connecting buffer portion
