Fluid Distribution Manifold With Feedback Valve Flow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fluid distribution systems, such as those for pool management, face challenges in achieving precise flow rates due to limitations in valve actuators, increased complexity and cost with multiple valves, and variability in operational conditions, leading to unstable performance and difficulty in integrating new devices.
Innovation Solution
A fluid distribution manifold with multiple valve assemblies and a controller system that monitors and adjusts flow rates independently through each outlet, allowing seamless integration of new devices and maintaining system stability by dynamically controlling valve operations based on real-time flow rate data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple valves and actuators are used to direct fluid flow to different fluid handling devices, then flow distribution capability is improved, but system complexity and cost increase
Solution Approach 1:
The system divides the fluid distribution function into multiple independent valve assemblies, each serving a specific fluid handling device. Each valve assembly is a self-contained unit with its own actuator, valve body, and flow control mechanism, allowing independent operation and simplifying the overall system architecture.
Solution Approach 2:
The manifold structure provides a universal platform that can accommodate multiple types of fluid handling devices (pumps, filters, heaters, water features) through standardized valve assemblies. The same basic valve assembly design can serve different devices, reducing the need for custom components and simplifying system integration.
2Ease of operation
If multiple valves with predefined flow rates are used, then flow control is provided, but precision and flexibility in flow rate setting are limited
Solution Approach 1:
The valve assemblies incorporate adjustable flow control mechanisms that allow dynamic modification of flow rates rather than fixed predefined settings. The valve members can be positioned at various angles or openings to continuously adjust flow rate, providing both ease of operation and precision control.
Solution Approach 2:
The system includes flow sensors that monitor actual flow rates and provide feedback to the control system. This feedback mechanism allows the actuators to adjust valve positions dynamically to achieve precise target flow rates, compensating for system variations and ensuring accurate flow control.
3Adaptability or versatility
If more valves and plumbing components are installed to serve additional fluid handling devices, then system functionality is improved, but installation time and labor cost increase
Solution Approach 1:
Each valve assembly is designed as a pre-assembled modular unit containing the valve body, actuator, and necessary connections. These modules can be manufactured independently and installed as complete units, significantly reducing on-site assembly time and labor requirements compared to traditional custom-installed valve systems.
Solution Approach 2:
The valve assemblies are designed to be integrated into the manifold structure, with components nested within each other (valve body within manifold port, actuator on valve body). This nested configuration reduces the overall space required and simplifies installation by eliminating separate mounting operations for each component.
4Adaptability or versatility
If traditional valve systems are used, then fluid distribution is achieved, but physical space required for valves and components increases
Solution Approach 1:
Multiple valve assemblies are integrated into a single manifold structure, merging what would traditionally be separate valve installations into one compact unit. The manifold serves as a common housing that accommodates multiple valve bodies and actuators in a space-efficient arrangement, reducing the overall footprint compared to individual valve installations.
Solution Approach 2:
The valve assemblies utilize nested configurations where valve bodies are positioned within manifold ports, actuators are mounted on valve bodies, and flow channels are integrated within the manifold structure. This nested arrangement minimizes the external dimensions and physical space required for the entire fluid distribution system.

AI summary
A housing assembly for a manifold includes a first housing with an inlet and a plurality of outlets, a second housing, and a valve retainer engaged with the first and second housings. The valve retainer includes a retention plate defined between first and second surfaces, a plurality of slot walls extending from the first surface, and a protruding edge that extends from a flanged lip and surrounds the plurality of slot walls. The retention plate defines a plurality of slots corresponding to the plurality of slot walls. The first housing may define a groove that receives the protruding edge, and the second housing may include a rim that engages the flanged lip of the valve retainer. Valve housings including first and second mating structures separated by wall segments may be positioned in outlets of the first housing and corresponding slots of the valve retainer.
