Solution Overview
Problem
Conventional fluid pump systems face inefficiencies in cooling both the motor and hydraulic fluid, often requiring larger and heavier designs with more components, and lack effective temperature control mechanisms to optimize performance across varying operational conditions.
Innovation Solution
A portable fluid pump system incorporating a cooling assembly with a single fan that cools both the motor and fluid conduit, utilizing a shroud and heat exchanger conduit with temperature sensors and a controller to manage airflow and heat transfer efficiently, allowing for reduced size, weight, and improved component lifespan.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate cooling mechanisms are used for motor and fluid, then cooling effectiveness is improved, but device complexity and weight increase
Solution Approach 1:
The patent combines the motor cooling and fluid cooling functions into a single integrated cooling assembly. The fan draws air that simultaneously cools the motor through direct airflow and cools the fluid through the heat exchanger conduit, eliminating the need for separate cooling systems while maintaining effective temperature control for both components.
Solution Approach 2:
The cooling assembly serves multiple functions: it cools the motor, cools the hydraulic fluid through the heat exchanger, and uses a single fan and airflow path for both purposes. This multi-functional design reduces the overall number of components while achieving comprehensive cooling effectiveness.
2Temperature
If larger cooling components are used, then temperature control is improved, but portability is reduced
Solution Approach 1:
The integration of motor cooling and fluid cooling into one compact assembly reduces the total volume and weight of cooling components compared to having separate systems. The shared fan and airflow path eliminate redundant parts, making the overall system more portable while maintaining effective temperature control.
3Device complexity
If integrated cooling is used, then device compactness is improved, but temperature control precision may worsen
Solution Approach 1:
The cooling assembly incorporates temperature sensors that monitor the temperature of both the motor and the hydraulic fluid. This feedback mechanism allows the system to detect temperature changes and adjust cooling performance accordingly, maintaining precise temperature control despite the integrated compact design.
