Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a simple disc with drilled holes is used as an oil slinger, then the structure is simple and easy to manufacture, but dielectric oil circulation is diminished and cooling/lubrication efficiency is reduced
Solution Approach 1:
The invention changes the geometric parameters of the oil slinger from simple drilled holes to complex 3D printed structures with curved surfaces and varying thickness. This transforms the oil flow parameters, creating more efficient circulation patterns while maintaining manufacturability through additive manufacturing.
Solution Approach 2:
The invention transitions from a 2D flat disc with holes to a 3D structure with varying thickness, curved surfaces, and multi-level features. This dimensional enhancement allows for more sophisticated oil deflection and circulation control without complicating the manufacturing process, as 3D printing naturally handles complex geometries.
2Device complexity
If a simple disc with drilled holes is used as an oil slinger, then the design is simple, but adaptability to different ESP motor shaft designs is limited
Solution Approach 1:
The 3D printed oil slinger design incorporates universal mounting features and adjustable geometries that allow it to adapt to multiple ESP motor shaft designs. The complex 3D structure can be customized through software while maintaining a universal base design, enabling one component to serve multiple applications across different manufacturers' equipment.
Solution Approach 2:
The invention introduces dynamic adjustability to the oil slinger design, where key parameters such as vane angles, hole positions, and surface curvatures can be modified based on the specific shaft design. This dynamic configuration capability allows the same basic component to adapt to various shaft geometries without requiring complete redesign.
3Ease of manufacture
If drilled holes are used in the oil slinger, then manufacturing is simple, but oil deflection control is limited
Solution Approach 1:
The invention changes the oil deflection control from simple hole geometry to complex 3D printed features including curved surfaces, varying thickness profiles, and multi-directional flow paths. These parameter changes enable precise control over oil deflection angles and flow distribution while maintaining ease of manufacture through additive manufacturing processes.
