Auto Stop Fluid Valve Cap Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid valves in fountains require removal of the fountain body cover to interrupt liquid flow for maintenance or filter replacement, which is time-consuming and inefficient.
Innovation Solution
An auto stop fluid valve system with a poppet valve mechanism that allows fluid flow interruption without removing the fountain cover, utilizing a filter and cap mechanism to control the poppet valve's open and closed positions, enabling fluid flow management within the fountain without disassembling it.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the fountain body cover is removed to interrupt liquid flow for maintenance, then the liquid flow can be stopped, but the maintenance time is increased and the process becomes inefficient
Solution Approach 1:
The valve assembly is segmented into modular components including a body, poppet valve, filter, and cap that can be independently accessed and maintained. The filter is contained in a separate filter chamber that can be serviced without removing the entire fountain cover, enabling targeted maintenance of specific components while the rest of the system remains intact.
Solution Approach 2:
The system enables self-service maintenance through the cap mechanism that allows operators to stop liquid flow and access the filter by simply removing the cap, without requiring disassembly of the fountain cover. This self-contained design allows end-users to perform basic maintenance tasks independently, significantly reducing maintenance time and eliminating the need for professional service for routine tasks.
2Ease of repair
If the fountain body cover is removed to access the valve mechanism, then maintenance can be performed, but the operational complexity increases
Solution Approach 1:
The valve assembly is divided into distinct functional segments: the main body housing, the poppet valve mechanism, the filter chamber, and the cap. This segmentation allows each component to be accessed, inspected, and maintained independently through the cap opening, simplifying the maintenance process while maintaining a relatively simple overall structure that does not require complex disassembly procedures.
3Productivity
If a traditional valve mechanism is used requiring cover removal, then the structure remains simple, but the operational efficiency decreases
Solution Approach 1:
The cap-operated valve mechanism enables users to independently control liquid flow and access the filter without requiring assistance or complex procedures. By simply removing the cap, users can stop the liquid flow via the poppet valve and access the filter for maintenance, empowering end-users to perform routine maintenance tasks themselves and significantly improving operational efficiency.
Solution Approach 2:
The poppet valve is pre-positioned within the valve chamber and automatically responds to cap removal by closing the flow path. This preliminary positioning and automatic response mechanism eliminates the need for additional操作步骤 during maintenance, allowing users to stop flow and access the filter in a single straightforward action, thereby maximizing operational efficiency.

Function Achieved in This Case
Facilitates quick maintenance and filter replacement by allowing water supply to be turned off and on without removing the fountain cover, significantly reducing maintenance time and simplifying the process.
Implementation Method 1
The poppet valve being capable of movement between open and closed positions... The poppet valve moving to the closed position when the filter is in the lowered position or removed

AI summary
An embodiment includes a valve with a filter in which the flow of water through the valve is stopped by lowering a filter within the valve. This movement of the filter allows a poppet valve to close, stopping the flow of water. Subsequent raising of the filter holds the poppet valve in the open position, allowing the flow of water through the filter for further use. Embodiments are found in drinking fountains and facilitate the maintenance of the drinking fountain by allowing a technician to shut off the water using a screwdriver without requiring the removal of the fountain cover.
