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

VSEngineering 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

Engineering Contradiction:
Improvedust removal qualityVSAvoidadaptability to three-dimensional surfaces
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

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.

Inventive Principle:
Principle #15Dynamics

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.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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

Engineering Contradiction:
Improveadaptability to three-dimensional surfacesVSAvoiddust removal quality
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

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.

Inventive Principle:
Principle #15Dynamics

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.

Inventive Principle:
Principle #1Segmentation

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

Engineering Contradiction:

Core Design Contradiction:
Ease of manufactureVSManufacturing precision

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
