Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coolant control valves (CCVs) lack the ability to provide continuous and variable coolant flow control for powertrain components in vehicles, limiting their efficiency and adaptability.
Innovation Solution
A coolant control valve (CCV) design incorporating an electric actuator, a rotary ball valve, and a rotary disc valve, which are actuated in unison to allow continuous variable positioning, enabling precise control over coolant flow through multiple inlets and outlets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional CCV design is used, then the structure is simple, but the coolant flow control is limited to fixed states without continuous variability
Solution Approach 1:
The valve body is divided into multiple segments including a first rotary valve body and a second rotary valve body, each with independent fluid openings. This segmentation allows each segment to control specific flow paths, enabling continuous variable coolant flow control while maintaining manageable structural complexity through modular design
Solution Approach 2:
The patent employs rotary valve bodies that can rotate to different positions to dynamically adjust coolant flow. The first and second rotary valve bodies can be actuated independently or together, providing dynamic control over multiple fluid openings to achieve continuous variable flow rates rather than fixed states
2Measurement precision
If multiple rotary valves are added for continuous flow control, then the flow control precision is improved, but the device complexity increases
Solution Approach 1:
The first rotary valve body and second rotary valve body are integrated within a single valve housing, sharing common actuation mechanisms and fluid passages. This merging approach allows multiple control functions to be achieved while reducing overall device complexity compared to separate valve assemblies
Solution Approach 2:
The rotary valve bodies are designed with multiple fluid openings that can serve different functions depending on rotation position. The same valve structure can control coolant flow to different outlets or adjust flow rates, providing multi-functionality that reduces the need for additional specialized components

AI summary
A coolant control valve includes an electric actuator and a valve housing having a first housing and a second housing. The first housing includes a first fluid chamber, at least one inlet, and at least one outlet. The second housing includes a second fluid chamber, at least one inlet and at least one outlet. A rotary ball valve is disposed within the first fluid chamber and actuated about a first axis by the electric actuator. A rotary disc valve, having at least one fluid opening, is disposed within the second fluid chamber and non-rotatably coupled to the rotary ball valve.
