Numerically Controlled Air Blowing Device Nozzle Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air blowing devices cannot be used as air blowing devices due to their small effective cross-sectional area in the cleaning-liquid feed channel, which prevents the ejection of dry air from the nozzle.
Innovation Solution
A numerically controllable air blowing device is designed with a feed base movable in multiple directions, a spindle housing with a rotatable spindle, and a nozzle block featuring slit and pipe nozzles, along with a fluid channel system that includes main pipes, annular channels, and connecting tubes to efficiently blow dry air onto objects, allowing for effective removal of water and other matter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a cleaning-liquid feed channel with small effective cross-sectional area is used, then the cleaning device can effectively deliver cleaning liquid to the cleaning tool, but it cannot be used as an air blowing device to eject dry air from the nozzle
Solution Approach 1:
The invention divides the fluid delivery system into separate channels: a cleaning-liquid feed channel for delivering cleaning liquid and a dry air channel for delivering dry air. This segmentation allows each channel to be optimized for its specific function, with the dry air channel having sufficient cross-sectional area for air ejection while the cleaning-liquid channel maintains its design for liquid delivery
Solution Approach 2:
The patent creates a multi-functional system where the same nozzle structure can handle both cleaning liquid delivery and dry air blowing operations. By providing separate feed channels for each fluid type, the nozzle becomes universal, capable of performing multiple functions (cleaning and drying) without requiring separate equipment
2Adaptability or versatility
If the feed base is made movable in multiple directions with numerical control, then the device can handle various objects and improve operational flexibility, but the device complexity increases
Solution Approach 1:
The feed base is designed with movable capabilities in multiple directions (vertical, horizontal, and rotational movements) under numerical control. This dynamic positioning system allows the nozzle to be precisely positioned relative to different workpieces, enabling the device to handle various objects with different sizes, shapes, and orientations while maintaining operational flexibility
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 air blowing device effectively removes water and other matter from machine parts by providing a controlled and intense air flow, capable of handling various objects through numerical control of the nozzle orientation and air pressure, while being more energy-efficient than traditional air compressors.
