Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid control assemblies in thermal management systems have complex structures that complicate the implementation of different communication manners among multiple communication ports.
Innovation Solution
A fluid control assembly with at least two columns of communication ports spaced apart in a circumferential direction, featuring a valve core with shared communication channels that facilitate communication between ports in multiple operation modes, simplifying the assembly's structure by reducing the need for individual channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple individual communication channels are provided for different communication modes, then reliable fluid control is achieved, but device complexity increases
Solution Approach 1:
The patent merges multiple communication channels into a single shared communication channel that can serve different port combinations through rotational positioning. Instead of providing separate dedicated channels for each communication mode, one shared channel is designed to communicate with different pairs of ports (e.g., first and second ports, third and fourth ports) depending on the rotational position of the valve core, thereby reducing structural complexity while maintaining control reliability.
Solution Approach 2:
The shared communication channel is designed with multi-functionality to perform multiple communication tasks. The same channel can establish communication between different port pairs by rotating the valve core to different positions, making the channel universal rather than dedicated to a single function, thus reducing the total number of channels needed.
2Device complexity
If a shared communication channel is used to reduce structure complexity, then device complexity decreases, but manufacturing precision requirements increase
Solution Approach 1:
The patent employs a dynamic solution where the valve core can rotate to different positions to establish different communication paths through the shared channel. This dynamic positioning allows the same channel to serve multiple functions, reducing structural complexity. The rotational mechanism enables precise alignment of the shared channel with different port pairs as needed, managing the precision requirements through controlled movement rather than static precision.
