Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dual-purpose cleaning tools for automobiles and workpieces face issues with inaccurate alignment, limited control over cleaning scope, and inability to perform coating processes, requiring high-pressure air and lacking in cleaning speed and quality.
Innovation Solution
An adjustable coating and cleaning gun with a hollow elliptical swinging spray pipe made of flexible material, allowing horizontal swinging for precise surface cleaning, and an adjustable sleeve for controlling cleaning angle and scope, enabling both dust removal and coating applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a free end outer nozzle is used in existing dual-purpose guns, then the structure is simple, but the cleaning scope cannot be controlled and alignment is inaccurate
Solution Approach 1:
The patent applies the dynamics principle by making the spray pipe swingable rather than fixed. The spray pipe can rotate and swing to adjust the cleaning scope and direction, allowing the user to control the cleaning area dynamically. This resolves the contradiction by enabling scope control through movement while maintaining operational simplicity.
Solution Approach 2:
The patent segments the spray system into a fixed spray head and a swingable spray pipe. This segmentation allows the spray pipe to be independently adjusted for scope control while the spray head remains stable. The division enables controlled flexibility without compromising overall structural simplicity.
2Force
If high pressure compressed air is used to increase cleaning force, then cleaning power is improved, but the swinging amplitude increases and alignment accuracy decreases
Solution Approach 1:
The swingable spray pipe design allows dynamic adjustment of the spray direction independent of pressure. Users can align the spray pipe precisely before applying high pressure, and the swing mechanism remains stable during operation. This resolves the contradiction by decoupling alignment precision from pressure-induced swinging.
Solution Approach 2:
The patent enables preliminary alignment of the spray pipe before high pressure air is applied. The swingable design allows users to position the spray pipe accurately in advance, lock it in place, and then activate high pressure cleaning. This preliminary positioning prevents misalignment caused by pressure-induced swinging.
3Adaptability or versatility
If existing dual-purpose gun structure is used, then it can blow dust and clean, but it cannot perform coating processing
Solution Approach 1:
The patent applies universality by designing the spray system to handle multiple types of materials - compressed air for dust blowing, cleaning solution for washing, and coating materials for surface treatment. The swingable spray pipe and adjustable spray head enable the same structure to perform dust removal, cleaning, and coating functions, achieving multi-functionality without significant structural 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 solution provides accurate surface positioning, high cleaning efficiency, and ease of use, allowing for adjustable cleaning angles and scopes, and supports both dust removal and coating processes.
Implementation Method 1
vertical rigidity of the swinging spray pipe is higher than horizontal rigidity so that the swinging spray pipe can only swing in a horizontal direction during operation
Implementation Method 2
a cleaning solution capillary spray pipe is arranged in the swinging spray pipe; and the cleaning solution capillary spray pipe penetrates through the spray pipe joint and is communicated with the cleaning solution storage kettle
