Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning turbines are ineffective in completely removing work residues from the work zone, leading to residual material on the product and potential clogging, and are often noisy and short-lived.
Innovation Solution
A cleaning turbine with an axial-symmetrical shape, featuring a base surface, upper surface, and circumferential surface with angularly spaced slits and radial lateral apertures, which generates a suction flow to remove chips through slits and powders through centrifugal action, and a concave base surface to enhance air flow and depression for effective residue removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a cleaning turbine generates air streams to move work residues, then the work zone becomes visible and cavities are cleared, but the turbine cannot effectively clean the affected zone leaving large quantities of residues on the product
Solution Approach 1:
The turbine body is segmented with multiple slits distributed around its circumference, creating multiple suction zones that collectively cover the entire work zone. This segmentation allows simultaneous removal of residues from different areas, significantly improving cleaning effectiveness while maintaining visibility of the work zone
Solution Approach 2:
The turbine introduces air streams as an intermediary medium that carries work residues from the work zone through the slits to the suction device. This intermediary air flow effectively transports both visible and fine residues, solving the problem of incomplete cleaning while maintaining work zone visibility
2Productivity
If the turbine rotates to generate air flow for suction, then work residues are removed from the work zone, but the turbine produces excessive noise
Solution Approach 1:
The turbine utilizes pneumatic principles by rotating to generate air streams that create depression for suction. The controlled air flow through the slits and lateral apertures achieves effective residue removal while the pneumatic design optimizes flow patterns to reduce turbulence and noise generation
3Ease of manufacture
If the turbine structure is simplified for ease of manufacture, then production cost decreases, but the turbine lifespan is reduced
Solution Approach 1:
The turbine employs segmented slits and lateral apertures that are integrated into the turbine body during manufacturing. This segmentation design, while requiring precision manufacturing, creates a robust structure where each slit and aperture acts as an independent flow path, distributing mechanical stresses and improving overall durability without significantly complicating the manufacturing process
Solution Approach 2:
The turbine body serves multiple functions: it generates rotational motion, creates air streams for suction, provides structural support, and directs flow through integrated slits and lateral apertures. This multi-functionality reduces the need for additional components, simplifying the overall structure while enhancing durability through optimized load distribution

Implementation Method 1
By making the cleaning turbine according to the present invention rotate, a flow of air is generated that, by depression, sucks the work residues from the work zone through the slits
Implementation Method 2
The finer work residues, that is, the powders, are expelled through the lateral apertures by the centrifugal effect conferred by the rotation of the turbine
