Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spraying devices for cleaning materials in automatic production lines, such as TFT-LCD manufacturing, suffer from poor liquid uniformity and cleaning effectiveness due to fixed or sinusoidal spraying trajectories, leading to inadequate cleaning and increased device wear from unnecessary vibrations.
Innovation Solution
A spraying device with a rotating sidewall featuring multiple sets of staggered spraying holes and an elongated spraying spout that aligns with different sets of holes during rotation, allowing for uniform liquid distribution across varying areas and reducing wear through controlled movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a stationary spraying device with fixed spraying holes is used, then the structure is simple and easy to manufacture, but the liquid spraying uniformity is poor and the cleaning effect is insufficient
Solution Approach 1:
The patent transforms the stationary spraying device into a dynamic one by enabling the sidewall to rotate or swing relative to the spraying spout. This dynamic movement allows the spraying spout to align with different sets of spraying holes at different times, creating variable spraying trajectories that improve liquid distribution uniformity across the material surface.
2Area of stationary object
If a swing-type spraying device is used to improve spraying coverage, then the liquid can reach more areas, but the spraying trajectory becomes sinusoidal causing poor uniformity and large vibrations
Solution Approach 1:
The patent segments the spraying holes into multiple sets arranged along the circumference of the rotating sidewall. Each set contains multiple spraying holes positioned at different locations. By rotating the sidewall, the system selectively activates different sets of holes, creating a segmented spraying pattern that covers a larger area while maintaining uniformity through controlled alignment with the infusion channel.
Solution Approach 2:
The patent replaces the sinusoidal swing motion with a controlled rotation or swinging motion of the entire sidewall assembly. This dynamic adjustment allows the spraying spout to align precisely with different sets of spraying holes, creating more uniform spray trajectories that cover larger areas without the harmful vibrations of traditional swing mechanisms.
3Area of stationary object
If a swing-type spraying device is used to expand spraying coverage, then more areas can be cleaned, but the device experiences large vibrations during acceleration and deceleration affecting product yield
Solution Approach 1:
The patent implements a controlled rotation or swinging mechanism for the sidewall that can operate smoothly without abrupt acceleration or deceleration. The rotating sidewall aligns with the spraying spout in a controlled manner, allowing the system to expand coverage area while minimizing vibrations that could affect product quality and yield.
4Area of stationary object
If a swing-type spraying device is used to improve spraying coverage, then the spraying area increases, but the device experiences larger wear due to continual swinging
Solution Approach 1:
The patent employs a controlled rotation or swinging mechanism for the sidewall that reduces mechanical stress and wear. The rotation-based approach allows for smoother operation compared to traditional swing mechanisms, extending the service life of the spraying device while maintaining the ability to cover larger spraying areas through the circumferential arrangement of multiple spraying hole sets.

Function Achieved in This Case
The device achieves improved liquid uniformity and cleaning efficacy by aligning the spraying spout with different sets of holes, reducing product yield impact from vibrations, and minimizing device wear through controlled rotation without acceleration or deceleration.
Implementation Method 1
liquid in the reservoir enter the spraying pipe through the open end of the spraying pipe, and is sprayed onto the material to be cleaned through the spraying holes of the spraying pipe
