Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaners are inadequate for dust removal on three-dimensional surfaces, particularly those with complex concave, convex, or concave-convex configurations, as they struggle to effectively reach and clean curved portions due to varying gaps between the dust-removing head and the workpiece.
Innovation Solution
A cleaner with a dust-removing head designed using 3D printing technology, featuring a work-corresponding face with a convex or concave offset configuration, and air-jetting holes of varying diameters to ensure uniform air flow and efficient dust removal, coupled with an air suction system to prevent surrounding pollution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional air jetting nozzle and suction nozzle are used for dust removal, then dust removal on flat surfaces is effective, but dust removal on three-dimensional surfaces with curved portions is insufficient
Solution Approach 1:
The dust-removing head is designed to be movable relative to the workpiece, allowing it to follow the contours of three-dimensional surfaces. The head can be positioned at multiple locations and adjusted to maintain optimal spacing from the surface, enabling effective dust removal across complex geometries including curved portions that would be inaccessible to fixed conventional nozzles.
Solution Approach 2:
The invention transitions from two-dimensional flat surface cleaning to three-dimensional surface cleaning by designing the dust-removing head with a work-corresponding face that matches the three-dimensional topology of the workpiece. This allows the cleaning system to operate effectively on surfaces with varying heights and curvatures, adding a vertical dimension to the cleaning capability.
2Adaptability or versatility
If the cleaner is customized to correspond to three-dimensional work, then adaptability to three-dimensional surfaces is improved, but gaps between parts of the work and dust-removing head greatly vary, causing insufficient dust removal on curved portions
Solution Approach 1:
The system employs dynamic positioning and spacing control of the dust-removing head to maintain optimal gap distances from the workpiece surface across varying geometries. The head can be independently positioned at multiple locations, allowing real-time adjustment to compensate for variations in surface curvature and ensure consistent dust removal performance across the entire three-dimensional workpiece.
Solution Approach 2:
The dust-removing head is divided into multiple independent dust-removing units, each capable of being positioned and controlled separately. This segmentation allows each unit to independently adapt to local surface variations, ensuring effective dust removal on curved portions while maintaining appropriate spacing from the workpiece surface.
3Ease of manufacture
If conventional air jetting is used, then simple flat surface cleaning is achieved, but dust removal on complicated concave, convex, or concave-convex three-dimensional work becomes more difficult
Solution Approach 1:
The cleaning system is segmented into multiple independent dust-removing units, each equipped with its own air jetting nozzle and suction nozzle. This segmentation allows each unit to independently target specific areas of complex three-dimensional surfaces, improving dust removal effectiveness on complicated geometries while maintaining the simplicity of individual unit design and operation.
Solution Approach 2:
The dust-removing head is designed as a universal module that can effectively clean various types of surfaces including flat, curved, concave, and convex geometries. By integrating multiple dust-removing units with adjustable positioning, the system achieves multi-functionality that handles complicated three-dimensional workpieces while maintaining ease of operation through standardized unit design.
