Six-Way Valve Selector Design for Compact HVAC Fluid Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current HVAC and radiator systems face challenges in efficiently switching between different temperature conditioning liquids for heating and cooling, often requiring complex valve arrangements and multiple valves to manage separate circuits, which can be bulky and prone to leakage.
Innovation Solution
A compact 6-way valve design with a moveable selector mechanism allows for seamless switching between two fluid sources by rotating a single control pin, enabling recirculation of either the first or second fluid source through the treatment unit, thus simplifying the control of temperature conditioning liquids in HVAC systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate valves are used to control different temperature conditioning liquid supplies, then the control function is achieved, but the device complexity and space requirements increase
Solution Approach 1:
The patent combines multiple separate valves into a single integrated 6-way valve body that can control both heating and cooling circuits. The valve body includes multiple valve seats and movable elements that work together to achieve the same control function that previously required separate valves, thereby reducing device complexity and space requirements while maintaining full adaptability.
Solution Approach 2:
The valve is designed as a universal 6-way valve that can handle both heating and cooling temperature conditioning liquids through a single device. The valve body incorporates multiple valve seats (first and second valve seats) and movable elements that can direct different fluid sources to appropriate outlets, enabling one valve to perform the work of multiple specialized valves.
2Adaptability or versatility
If multiple separate valves are used to manage separate circuits, then the control function is achieved, but the risk of leakage increases
Solution Approach 1:
By merging multiple valve functions into a single integrated valve body with unified sealing mechanisms, the patent reduces the number of potential leakage points. The valve body includes multiple valve seats and movable elements that create sealed pathways for different circuits, eliminating the need for separate valves that would each have their own sealing interfaces and potential failure points.
3Volume of moving object
If a compact valve design is used, then the space requirements are reduced, but the ease of maintenance may be affected
Solution Approach 1:
The patent segments the valve into distinct functional components including a valve body, movable elements, and valve seats that can be accessed independently. The compact design maintains internal integration for space efficiency while providing external access points and modular components that facilitate maintenance without requiring complete disassembly, thus balancing compactness with ease of repair.

AI summary
A valve for an indoor temperature regulating system, includes a fixed valve housing having at least six valve connections and a valve selector for switching between providing a circulating flow from a first fluid source and a second fluid source thereby enabling fluid of different temperatures to a treatment unit. The valve selector includes a disc plate provided with openings and the valve main body is provided with valve openings connected via channels to the valve connections The valve selector and valve main body are slideable against each other. In the first mode valve openings are in register with lower disc plate openings such that two flow paths connecting the first fluid source with the treatment unit are enabled and in the second mode valve openings are in register with lower disc plate openings such that two flow paths connecting the first fluid source with the treatment unit are enabled.
