Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-zone hydronic heating or cooling systems have complex and expensive supply manifolds due to the need for individual actuators for each zone valve, increasing complexity and cost.
Innovation Solution
A novel supply manifold design featuring a single actuator that can be displaced along a longitudinal axis and orthogonally positioned to individually actuate any of the valves, using a screw drive and solenoid mechanism to open or close quarter-turn ball valves, reducing the need for multiple actuators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple actuators are used to actuate each zone valve individually, then each valve can be controlled independently, but the manifold becomes complex and expensive
Solution Approach 1:
A single actuator is designed to perform multiple functions by sequentially actuating different zone valves through linear displacement along the manifold. The actuator serves all valves in sequence rather than each valve having its own dedicated actuator, reducing overall system complexity while maintaining independent control capability.
Solution Approach 2:
The actuator is made movable along the longitudinal axis of the manifold to dynamically access different valve positions. This dynamic positioning allows one actuator to serve multiple stationary valves, transforming a static one-to-one actuator-valve relationship into a dynamic one-to-many relationship.
2Ease of operation
If multiple actuators are used to actuate each zone valve individually, then each valve can be controlled independently, but the manufacturing cost increases
Solution Approach 1:
By designing a single actuator that can service multiple zone valves through linear displacement, the manufacturing cost is reduced compared to installing separate actuators on each valve. The universal actuator design eliminates the need to manufacture, purchase, and install multiple identical actuator units.
Solution Approach 2:
The function of multiple actuators is merged into a single actuator unit that performs the combined function of all valve actuations. This consolidation reduces component count, simplifies manufacturing, and lowers overall system cost while maintaining the capability to independently control each zone valve.
3Device complexity
If a single actuator is used to actuate multiple valves, then the manifold is simplified and cost is reduced, but the actuator must be displaced to access different valves
Solution Approach 1:
The actuator is designed to dynamically displace along the longitudinal axis to access different valve positions sequentially. This dynamic movement capability allows a single actuator to reach multiple stationary valves, simplifying the manifold structure while enabling independent control of each zone through controlled actuator positioning.

Implementation Method 1
The manifold has a first displacement mechanism, e.g. a screw drive driven by an electric motor, for displacing the actuator along a longitudinal axis
Implementation Method 2
The manifold has a second displacement mechanism, e.g. a solenoid, for displacing the actuator orthogonally to the longitudinal axis

AI summary
A supply manifold for a hydronic heating or cooling system has a housing a plurality of valves disposed on respective outlets of the housing in a linear arrangement. Each outlet is adapted to connect to a conduit for delivering the liquid to a zone. Each valve controls a flow of the heating or cooling liquid into each respective conduit. The supply manifold has a single actuator for individually actuating one of the valves. A first displacement mechanism, e.g. a screw drive power by an electric motor, displaces the actuator along a longitudinal axis parallel to the linear arrangement of the valves to thereby access any one of the valves. A second displacement mechanism, e.g. a solenoid, displaces the actuator orthogonally to the longitudinal axis to thereby cause engagement or disengagement of the actuator with a selected one of the valves for opening or closing.
