Firefighters face inconvenience and operational challenges due to the need to carry multiple tools for adjusting different types of standpipe pressure regulating valves, which can lead to loss of essential tools during emergencies.
Innovation Solution
A multi-functional standpipe operations spanner tool that includes a body with a handle, hex sockets, adjustable wrench, and spanners designed to fit various standpipe pressure regulators and valves, allowing for adjustment of pressure and operation of different valve types with a single tool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If firefighters carry multiple separate tools for different valve types, then they can adjust all types of standpipe pressure regulating valves, but the tool quantity and complexity increase
Solution Approach 1:
The patent combines multiple valve adjustment tools (hex socket wrench, spanner, and adjustable wrench) into a single integrated tool. The handle contains a hex socket for pressure regulator adjustments, while the distal end features both a spanner and adjustable wrench for valve adjustments, eliminating the need to carry multiple separate tools.
Solution Approach 2:
The integrated tool is designed to perform multiple functions: the hex socket portion adjusts pressure regulating valves, the spanner adjusts valve bonnets, and the adjustable wrench handles various valve types. This multi-functional design allows a single tool to replace several specialized tools.
2Adaptability or versatility
If firefighters carry multiple separate tools for different valve types, then they can adjust all types of standpipe pressure regulating valves, but the risk of losing essential tools increases
Solution Approach 1:
By merging multiple essential valve adjustment tools into one integrated device, the patent ensures that all necessary functions are contained in a single tool. This eliminates the risk of losing individual components, as the hex socket, spanner, and adjustable wrench are permanently integrated into one unit that firefighters carry.
3Ease of manufacture
If separate tools are used for each valve type, then each tool can be optimized for its specific function, but the ease of operation decreases due to tool selection and switching
Solution Approach 1:
The integrated tool allows firefighters to perform all valve adjustment operations with a single device. The handle provides hex socket access for pressure regulators, while the distal end offers both spanner and adjustable wrench capabilities, eliminating the need to select and switch between multiple specialized tools during emergency operations.
