Hydrant Nozzle Cap Adapter for Multi-Style Nozzle Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fire hydrant nozzle caps configured for one style of nozzle connection often cannot be used with different styles, limiting compatibility and versatility in mounting various systems.
Innovation Solution
A nozzle cap adapter with an adapter ring and nozzle connector that can engage different nozzle styles, such as U.S. Storz, allowing for secure mounting and sealing across various nozzle connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a nozzle cap is configured for one specific style of nozzle connection, then it can securely connect to that particular nozzle type, but it cannot be used with other nozzle styles, limiting compatibility
Solution Approach 1:
The adapter ring serves as an intermediary component between the nozzle cap and various nozzle styles. The adapter ring includes different connector types (e.g., threaded connector, U.S. Storz connector, Canadian Storz connector) that can be selectively engaged with corresponding nozzles, enabling the single nozzle cap to interface with multiple nozzle styles without requiring multiple specialized caps
Solution Approach 2:
The adapter ring is designed with multi-functionality to connect with multiple nozzle styles (threaded, U.S. Storz, Canadian Storz). This universal design allows a single adapter ring to perform the function of multiple specialized connectors, thereby improving compatibility while maintaining a unified structure
2Adaptability or versatility
If multiple specialized nozzle caps are used for different nozzle styles, then each cap can be optimized for its specific nozzle type, but the overall system complexity increases and versatility decreases
Solution Approach 1:
The invention merges multiple connector functionalities into a single adapter ring structure. Instead of requiring separate nozzle caps for threaded nozzles, U.S. Storz nozzles, and Canadian Storz nozzles, the adapter ring integrates all these connection capabilities into one component, reducing the total number of parts needed in the system
3Adaptability or versatility
If a universal adapter is designed to fit multiple nozzle styles, then compatibility improves, but the secure connection and sealing reliability may be compromised
Solution Approach 1:
The adapter ring incorporates different connector types at different locations, each optimized for its specific nozzle style. The threaded connector provides rotational engagement for threaded nozzles, while the bayonet-style U.S. and Canadian Storz connectors provide quarter-turn engagement for their respective nozzles. Each local connection interface maintains high reliability through its specialized design

AI summary
Example aspects of a nozzle cap adapter, a nozzle cap assembly, and a method for method for mounting a nozzle cap to a fire hydrant nozzle are disclosed. The nozzle cap adapter can comprise an adapter ring defining a first adapter ring end, a second adapter ring end opposite the first adapter ring end, and an interior void extending from the first adapter ring end to the second adapter ring end; a nozzle connector extending from the second end of the adapter ring, the nozzle connector configured to rotatably engage a fire hydrant nozzle; and a latch coupled to the adapter ring and configured to removably lock the nozzle cap adapter onto the fire hydrant nozzle.
