Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If an expanding core axis is used to spray spherical cores with small apertures, then positioning precision is improved, but productivity deteriorates due to individual spraying only
Solution Approach 1:
The spraying tool is segmented into multiple independent positioning cores (first positioning core, second positioning core, etc.) arranged along the axial direction, each capable of independently positioning and spraying a spherical core. This allows multiple spherical cores to be sprayed simultaneously while maintaining individual positioning precision for each core.
Solution Approach 2:
The invention transitions from single-point spraying to multi-point spraying by arranging positioning cores along the axial dimension. The first positioning core, second positioning core, and subsequent cores are distributed at different axial positions, enabling parallel processing of multiple spherical cores without compromising the precise positioning capability in the radial direction.
2Productivity
If multiple spherical cores are sprayed simultaneously, then productivity is improved, but positioning precision deteriorates due to increased complexity
Solution Approach 1:
The tool body is divided into multiple independent positioning core units, each with its own positioning mechanism. This segmentation allows each core to maintain independent positioning accuracy while contributing to overall multi-core spraying capability, preventing the deterioration of precision that would normally accompany increased complexity.
Solution Approach 2:
Each positioning core serves as a universal positioning unit that can handle spherical cores with consistent dimensional and coaxiality requirements. The standardized design of positioning cores ensures that the same precision standards are maintained across all spraying positions, enabling multiple cores to be sprayed simultaneously with uniform quality.
3Manufacturing precision
If a complex positioning mechanism is used to ensure precise positioning of steel balls, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The positioning function is extracted and concentrated into dedicated positioning cores that are separate from the main tool body. Each positioning core (first positioning core, second positioning core, etc.) is an independent component designed specifically for positioning spherical cores, simplifying the overall structure by separating positioning functions from spraying functions and reducing interdependencies.
Solution Approach 2:
The positioning cores are pre-configured with precise geometric features (such as cylindrical surfaces and positioning holes) that inherently provide positioning accuracy before the spraying process begins. The steel balls are positioned by simply being placed into the positioning holes of the positioning cores, eliminating the need for complex adjustment mechanisms during operation.

Function Achieved in This Case
The tool enables simultaneous spraying of multiple spherical cores with enhanced efficiency by ensuring precise positioning and distribution, simplifying the process and increasing throughput.
Implementation Method 1
Before a spherical core is fixed to the spraying spindle, spot-welding of a steel ball in an inner hole of the spherical core is required to be performed for the purpose of positioning.

AI summary
A spherical core spraying tool comprises a spraying spindle and connecting rods; the spraying spindle is circumferentially provided with a plurality of protruding rings, and is axially provided with a strip-shaped groove; the connecting rods are disposed in the groove; one end of the spraying spindle is a power input end, and the other end is provided with a locking sleeve; the groove runs through the protruding rings. By spot-welding steel balls in an inner hole of a spherical core and fitting the spherical core over the spraying spindle, the steel balls are stuck in the groove of the spraying spindle, and the both sides of the steel balls are tightened by means of the connecting rods in abutting-against fashion, so that a plurality of spherical cores is fixed together with the spraying spindle, and the plurality of spherical cores can be spray-coated simultaneously, thereby improving the efficiency.
