Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Submersible cooling pumps face challenges with fixed stud sets that cannot adapt to varying liquid container depths, requiring multiple pump sizes, and have inconvenient and dangerous methods for observing motor rotation direction and lack dust protection.
Innovation Solution
A submersible cooling pump design with a removable support pipe for adjustable stud length, a screw-fastened motor cover for easy inspection, arrow-shaped sight holes for direct rotation direction observation, and a protective cover to prevent dust and debris entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed stud set is used to connect the motor set with the impeller set, then the structure is simple, but the length cannot be changed to adapt to different depths of the liquid container, requiring multiple pump sizes
Solution Approach 1:
The stud set is divided into multiple segments (first stud, second stud, third stud) that can be selectively assembled. Each stud has a specific length, and by choosing different combinations, the overall length can be adjusted to match different liquid container depths, eliminating the need for multiple complete pump sizes.
Solution Approach 2:
The stud set configuration is made dynamic and adjustable rather than fixed. The patent allows selection of different stud combinations based on the required depth, transforming the static structure into an adaptable one that responds to varying operational requirements.
2Ease of operation
If an indicator point is provided on the blades of the motor set for observing rotation direction, then the rotation direction can be determined, but it requires removing the motor cover which is inconvenient and dangerous
Solution Approach 1:
The indicator structure is nested within the motor assembly. The indicator point is positioned on the motor shaft or connected components that are visible through the motor cover, allowing observation without disassembly. The indicator rotates along with the motor shaft, providing rotation direction information while remaining protected within the motor housing.
3Temperature
If heat dissipating holes are provided in the motor cover, then heat generated by the motor can be dissipated, but dust or chips can enter the pump and cause damages
Solution Approach 1:
The motor cover is designed with differentiated local qualities: certain areas have heat dissipating holes for thermal management, while other areas maintain solid coverage for protection. The cover is not uniformly perforated but has strategically placed openings that balance heat dissipation needs with contamination prevention.
