Multi-Interface Service Stop for Flexible Valve Shutoff
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional service stops in valve assemblies often require specific tools for operation, which can be problematic if the tool interface is damaged or not readily available, limiting flexibility and ease of use, especially in large buildings where shutting off the entire water supply is impractical.
Innovation Solution
A valve assembly with a service stop featuring multiple tool interfaces that can receive different types of hand tools, such as flathead screwdrivers, hex wrenches, nut drivers, and others, allowing for flexible operation without the need for a single specific tool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a service stop uses a single specific tool interface, then the structure is simple and easy to manufacture, but the flexibility and ease of operation are limited when the tool is damaged or not available
Solution Approach 1:
The service stop is designed with multiple tool interfaces (first tool interface and second tool interface) that can accommodate different types of tools. This allows the same service stop to be operated by various tools such as flathead screwdrivers, hex wrenches, or nut drivers, providing universality and adaptability without requiring multiple separate components.
Solution Approach 2:
Multiple tool interfaces are integrated into a single service stop body. The first tool interface and second tool interface are combined in one structure, allowing the service stop to function with multiple tool types simultaneously. This merging approach provides versatility while maintaining a unified, manageable structure.
2Ease of operation
If a service stop accepts multiple tool types, then the ease of operation and flexibility improve, but the device complexity increases
Solution Approach 1:
The service stop incorporates multiple tool interfaces that enable operation with different tool types. This universality ensures that users can operate the service stop with whichever tool is most convenient or available, significantly improving ease of operation without requiring complex external systems.
Solution Approach 2:
Multiple tool interfaces are merged into a single service stop assembly, creating a compact design that provides operational flexibility. The combined structure allows various tools to access the service stop without requiring separate mechanisms for each tool type.
3Reliability
If the service stop has multiple tool interfaces, then the reliability improves by reducing dependency on a single tool, but the manufacturing complexity increases
Solution Approach 1:
The service stop is designed with multiple tool interfaces that can accommodate different tool types, ensuring reliable operation regardless of which tool is used. This multi-functionality provides redundancy and reliability without requiring complex external systems or multiple separate components.
Solution Approach 2:
Multiple tool interfaces are combined into a single service stop body that can be manufactured as one integrated component. This merging approach allows for streamlined production processes while providing reliable, multi-tool compatibility.

AI summary
A valve assembly includes an inlet to receive a fluid into the valve assembly, an outlet to discharge the fluid from the valve assembly and a service stop coupled to the inlet or the outlet. The service stop can rotate relative to the inlet or the outlet to control a flow of the fluid through the inlet or the outlet. The service stop can include a first tool interface to receive a first hand tool and transfer a first torque from the first hand tool to the service stop to facilitate rotating the service stop using the first hand tool. The service stop can include a second tool interface to receive a second hand tool different from the first hand tool and configured to transfer a second torque from the second hand tool to the service stop to facilitate rotating the service stop using the second hand tool.
