Twin Return Port Water Pump for Multi-System Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current water pumps in engine assemblies typically have only one return port, limiting their ability to supply water to multiple systems simultaneously without complex hose arrangements, which is problematic due to space constraints.
Innovation Solution
A water pump design featuring twin return ports with corresponding connectors and hoses, allowing for the independent supply of water to multiple systems such as the thermostat and cab heater, facilitated by a cast pad with side-by-side ports and identically configured connectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a water pump has only one return port, then the structure is simple, but it cannot supply water to multiple systems simultaneously without complex hose arrangements
Solution Approach 1:
The single return port is segmented into multiple return ports (first return port and second return port) on the pump housing. This allows water to be distributed to multiple systems (thermostat, cab heater, etc.) simultaneously through separate ports, eliminating the need for complex branched hose arrangements and reducing installation complexity while improving versatility
2Adaptability or versatility
If branched hoses are used to supply water to multiple systems, then multiple systems can be served, but space constraints make the arrangement difficult
Solution Approach 1:
Multiple return ports are positioned at different locations and orientations on the pump housing (top horizontal pad, side walls, etc.), utilizing three-dimensional space effectively. This spatial distribution of ports eliminates the need for long branched hoses extending across limited engine bay space, reducing the area required for hose arrangements while maintaining the ability to serve multiple systems
