Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dust removing devices lack a flow rate adjustment mechanism for both the ejection and suction of compressed fluid, leading to inefficient removal of dust from holes in objects.
Innovation Solution
A dust removing device equipped with an ejection volume adjustment part to control the flow rate of compressed fluid ejected from a jet nozzle and a suction volume adjustment part to control the suction flow rate, allowing for efficient removal of dust by adjusting these flow rates and generating vacuum suction before ejection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional dust removing devices eject compressed fluid from a jet nozzle into a hole without flow rate adjustment, then the device structure is simple, but dust cannot be efficiently removed
Solution Approach 1:
The patent applies parameter changes by introducing flow rate adjustment mechanisms that allow dynamic control of compressed fluid ejection flow rate and vacuum suction flow rate. This enables optimization of dust removal efficiency by adjusting parameters according to different working conditions, resolving the contradiction between simple structure and high productivity.
Solution Approach 2:
The patent implements dynamics by making the flow rates of ejection and suction adjustable rather than fixed. The ability to dynamically change flow rates allows the system to adapt to varying dust conditions and hole characteristics, improving productivity while maintaining reasonable structural complexity.
2Productivity
If dust is removed by ejecting compressed fluid at positive pressure only, then the device structure is simple, but dust cannot be efficiently removed
Solution Approach 1:
The patent merges two functions - ejection of compressed fluid at positive pressure and vacuum suction at negative pressure - into a single integrated system. This combination allows dust to be both loosened by positive pressure and efficiently removed by negative pressure, significantly improving dust removal efficiency while maintaining unified device operation.
Solution Approach 2:
The patent ensures continuous useful action by coordinating the ejection and suction processes to work simultaneously and continuously. The compressed fluid continuously ejects to loosen dust while vacuum suction continuously removes it, creating an uninterrupted dust removal process that maximizes productivity.
3Productivity
If flow rate adjustment mechanism is added to control ejection and suction flow rates, then dust removal efficiency is improved, but energy consumption increases
Solution Approach 1:
The patent uses parameter changes to optimize the balance between productivity and energy consumption. By allowing adjustment of flow rates, the system can operate at optimal efficiency points for different dust conditions, avoiding excessive energy consumption while maintaining high dust removal efficiency. The adjustable parameters enable energy-efficient operation tailored to specific working conditions.
4Productivity
If flow rate adjustment mechanism is added to control ejection and suction flow rates, then dust removal efficiency is improved, but device complexity increases
Solution Approach 1:
The patent applies parameter changes through flow rate adjustment mechanisms that add control capability without fundamentally changing the core ejection and suction functions. The adjustment mechanisms modify operational parameters rather than requiring complete structural redesign, thus improving productivity while limiting the increase in device complexity.

AI summary
A needle screw fitted to a compressed fluid supply part that is provided on a nozzle main body of a dust removing device adjusts the jet flow rate of a first compressed fluid from a jet nozzle by adjusting the flow path area of a first fluid supply path. Meanwhile, the suction flow rate of a second compressed fluid to be discharged into a discharge flow path is adjusted by adjusting the flow path area of a second fluid supply path by turning a nozzle main body-side adjustment screw that is provided on the nozzle main body and a suction nozzle-side adjustment screw that is provided on a suction nozzle.
