Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing siphon-type airbrushes have a complex structure that increases manufacturing costs and difficulties in processing, leading to instability and low coaxiality between the nozzle and sprayer, affecting their performance.
Innovation Solution
A siphon-type airbrush design with a front handle connected to a tail handle, featuring a siphon channel, air inlet valve, and a nozzle base with threaded connections, along with sealing rings and an adjustable mechanism to ensure stability and coaxiality, simplifying the structure and processing while reducing manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the nozzle is installed at the front end of the front handle by means of a sprayer, then the airbrush can be assembled, but the structure becomes complicated and processing difficulty increases
Solution Approach 1:
The invention introduces a separate nozzle base component that connects the sprayer to the front handle. This segmentation allows the complex connection to be divided into manageable parts: the nozzle base with threaded hole receives the sprayer, while its outer threaded end connects to the front handle. This modular approach simplifies the overall structure and ease of manufacture.
2Reliability
If the nozzle is connected with the front handle merely through the sprayer, then the structure is simpler, but the positional stability of the nozzle becomes difficult to maintain
Solution Approach 1:
The nozzle base serves as an intermediary component between the sprayer and the front handle. It provides a stable mounting platform with a threaded hole that securely receives the sprayer, ensuring the nozzle maintains its positional stability and coaxiality during operation, while the threaded connection to the front handle provides firm fixation.
3Manufacturing precision
If the nozzle is connected merely through the sprayer, then fewer components are used, but the coaxiality between the nozzle and sprayer decreases
Solution Approach 1:
By introducing the nozzle base as a separate component with a threaded hole for the sprayer and a threaded outer end for the front handle, the invention creates a dedicated mounting interface that ensures proper alignment and coaxiality between the nozzle and sprayer, while maintaining a reasonable structure complexity.
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 simplifies the structure, reduces manufacturing costs, and enhances the stability and coaxiality of the nozzle and sprayer, improving the airbrush's performance and ease of use.
Implementation Method 1
the principle of the siphon-type airbrush is that compressed air is used to generate a negative pressure at the position of the nozzle, such that the paint in the paint bottle is siphoned into the nozzle to be sprayed out
Implementation Method 2
compressed air is used to generate a negative pressure at the position of the nozzle
Implementation Method 3
the rear end of the nozzle base is in threaded connection with the front handle; and the front end of the nozzle base is in threaded connection with the sprayer
Implementation Method 4
sealing rings are respectively disposed between the front handle and the nozzle base, between the nozzle base and the sprayer, and between the nozzle base and the nozzle body
