Water Pump Mounting Structure for Even Force Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water pump mounting structures in internal combustion engines face challenges in evenly distributing the weight of heavy actuators, leading to potential displacement and reduced assembly performance, particularly when the actuator is heavy.
Innovation Solution
The water pump mounting structure incorporates upper and lower extending portions on the water pump housing with multiple fastening points that are perpendicular to the joint face, allowing for even distribution of forces and secure attachment to the engine body, using a combination of first and second fastening portions to support the pump driving shaft and actuator, ensuring stability and sealability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single fastening point is used to mount the water pump housing, then the mounting structure is simple, but the weight of heavy actuators concentrates at one point causing displacement and reduced assembly performance
Solution Approach 1:
The mounting structure is segmented into multiple fastening points (first and second fastening portions) distributed across the water pump housing. This segmentation distributes the actuator weight across multiple attachment points to the engine body, preventing concentration of load at a single point and thereby eliminating displacement while maintaining structural simplicity.
2Device complexity
If fastening portions are positioned away from the pump driving shaft, then the mounting structure is simpler, but the force distribution becomes uneven causing displacement
Solution Approach 1:
The fastening portions are strategically positioned at specific locations on the water pump housing that optimize force distribution. The first fastening portion is located at one end of the upper extending portion while the second fastening portion is positioned between the pump driving shaft and the first fastening portion. This local optimization ensures even force distribution across the housing, preventing displacement while maintaining structural simplicity.
