Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pump devices, particularly submersible pumps, face challenges in effectively cooling their components, especially the drive shaft end bearings, which can lead to reduced efficiency and reliability due to inadequate heat management.
Innovation Solution
Incorporating a bearing receptacle with integrated cooling channels that utilize a high thermal conductivity fluid to cool the drive shaft end bearings, combined with a plate-like design and multiple passage openings for flexibility and efficient fluid flow, and potentially produced through casting for simplified production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If cooling channels are integrated into the bearing receptacle, then cooling efficiency of the drive shaft end bearing is improved, but device complexity increases
Solution Approach 1:
The cooling channels are integrated directly into the bearing receptacle structure, merging the cooling function with the bearing support function. This eliminates the need for separate cooling components and reduces overall device complexity while improving cooling efficiency of the drive shaft end bearing.
Solution Approach 2:
The bearing receptacle serves multiple functions: it supports the drive shaft end bearing and simultaneously provides cooling through integrated channels. This multi-functionality reduces the number of separate components needed, resolving the contradiction between improved cooling and reduced complexity.
2Temperature
If multiple cooling channels are added to improve cooling performance, then heat management improves, but manufacturing complexity increases
Solution Approach 1:
The cooling channels are designed with optimized parameters including diameter, length, and routing that balance cooling performance with manufacturability. The channels are configured to achieve effective heat removal while maintaining feasibility for standard manufacturing processes.
Solution Approach 2:
The cooling channels are strategically positioned and dimensioned to provide targeted cooling where heat generation is highest in the bearing receptacle. This localized approach optimizes cooling efficiency without requiring excessive channel complexity throughout the entire structure.
3Adaptability or versatility
If the bearing receptacle is designed with plate-like form and passage openings, then adaptability and flexibility improve, but structural strength may be reduced
Solution Approach 1:
The bearing receptacle is designed as a plate-like structure with multiple passage openings that segment the solid material into a patterned structure. This segmentation provides flexibility and adaptability for various mounting configurations while the overall plate structure maintains sufficient structural strength through its geometry and material properties.
