Valve Mounting Assembly Spoon Flow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing valve systems that control air flow through inlets, outlets, and exhausts are complex due to their reliance on check valves and steel balls, which complicates the arrangement and efficiency of fluid flow control.
Innovation Solution
A valve mounting system with an upper and lower plate configuration, where a spoon moves about an axis to control fluid flow through an opening, utilizing a lever assembly and a cone-shaped threaded fastener to adjust the spoon's position and restrict or allow fluid flow, allowing for precise control and increased airflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If check valves and steel balls are used to control air flow, then flow control function is achieved, but device complexity increases
Solution Approach 1:
The patent extracts and eliminates the complex check valve and steel ball mechanism from the air flow control system. Instead, it uses a simple spoon-shaped member that can be positioned to block or allow flow through the inlet passage, achieving the same flow control function with significantly reduced structural complexity.
Solution Approach 2:
The patent inverts the traditional approach by using a positive blocking mechanism (spoon member that can be actively positioned to block the inlet) rather than a passive check valve system. This inversion allows for more precise and reliable flow control while simplifying the overall device structure.
2Device complexity
If a simple opening is used for air flow, then device complexity is reduced, but flow control precision is insufficient
Solution Approach 1:
The patent implements a dynamic flow control mechanism where the spoon-shaped member can be positioned at different locations within the inlet passage. This dynamic positioning capability allows precise control of air flow while maintaining a simple overall structure, as the same component can provide various flow restriction levels based on its position.
Solution Approach 2:
The spoon-shaped member acts as an intermediary element between the simple opening and precise flow control requirements. By positioning this intermediary component at different locations, the system achieves precise flow control without requiring complex structural modifications to the basic opening design.
3Measurement precision
If spoon position is adjusted to control flow, then flow control precision is improved, but device complexity increases
Solution Approach 1:
The spoon-shaped member is designed to be self-positioning through the interaction of air flow and the member itself. The flow dynamics naturally guide the spoon to appropriate positions, eliminating the need for complex external actuation mechanisms while maintaining precise flow control capability.
Solution Approach 2:
The patent replaces complex mechanical actuation systems with a flow-driven positioning mechanism. The air flow itself provides the force to position the spoon-shaped member, substituting elaborate mechanical control systems with a simpler flow-based control approach that achieves the same precision.

AI summary
A valve mounting system includes an upper plate including an upper inlet, an upper outlet, and an upper exhaust. A lower plate includes a lower inlet, a lower outlet, and a lower exhaust that are aligned with the upper inlet, the upper outlet, and the upper exhaust, respectively to define an inlet, an outlet and an exhaust, respectively. A spoon moves about an axis to control a flow of fluid through an opening. The opening is one of the inlet, the outlet and the exhaust.
