Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If a conventional centrifugal projector is used to project projection material onto a workpiece, then surface treatment can be performed, but the amount of projection material used is relatively large
Solution Approach 1:
The control cage is divided into multiple segments with individual openings, allowing precise control over projection material discharge locations. This segmentation enables concentrated projection onto specific workpiece areas, reducing overall material consumption while maintaining effective surface treatment coverage.
Solution Approach 2:
The invention introduces angular positioning of openings in the control cage relative to the workpiece, adding a dimensional control aspect. By adjusting the angular positions and inclining angles of blade surfaces, the projection material distribution is optimized in three-dimensional space, achieving concentrated projection that reduces material usage.
2Loss of substance
If projection material is projected in a concentrated manner, then material usage is reduced, but the projection distribution must be precisely controlled
Solution Approach 1:
The blade surfaces are pre-inclined at specific angles (15-45 degrees) relative to the radial direction before projection material contact. This preliminary angular configuration ensures that projection material is automatically concentrated and directed onto the workpiece in a controlled manner, achieving precise projection distribution without requiring complex real-time adjustments.
Solution Approach 2:
The invention optimizes specific parameters including the inclining angles of blade surfaces (15-45 degrees), the angular positions of control cage openings, and the rotational speed of the impeller. By carefully adjusting these parameters, the projection material distribution is precisely controlled to achieve concentrated projection with minimal material usage.
