Sprinkler Informational Plug Segmentation Universality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Irrigation devices, such as sprinklers, require a way to easily customize and indicate the type of water they discharge, including non-potable water sources, without the need for multiple device versions, and to convey additional information like location or advertising.
Innovation Solution
A removable informational plug that can be attached to sprinklers, featuring different colors and designs to indicate water type, location, or advertising, using a keyway locking mechanism for secure attachment and easy removal, made from materials like plastic with grip elements and markings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If separate versions of sprinklers are created for different water types, then clear identification of water type is achieved, but device complexity and inventory requirements increase
Solution Approach 1:
The identification function is segmented from the main sprinkler body and placed on a separate, removable plug. This allows the same sprinkler body to be used with different plugs for different water types, eliminating the need for multiple complete device versions while maintaining clear identification.
Solution Approach 2:
A universal sprinkler body design is created that can accommodate multiple types of informational plugs. The standardized interface allows a single sprinkler model to serve multiple functions by simply changing the plug, reducing inventory complexity while maintaining clear water type identification.
2Ease of operation
If informational plugs are made easily removable, then customization and maintenance become simpler, but secure attachment and debris prevention become more difficult
Solution Approach 1:
The plug is designed as a separate, removable component with distinct engagement features. This segmentation allows for simple insertion and removal operations while incorporating built-in mechanisms like lips and grooves that provide secure attachment and prevent debris entry when properly installed.
Solution Approach 2:
An intermediary mechanical interface (keyway and key mechanism) is introduced between the plug and sprinkler body. This intermediary structure enables easy removal by aligning and pulling, while simultaneously providing secure attachment through interlocking features that prevent accidental dislodgement and block debris pathways.
3Adaptability or versatility
If multiple informational plugs are stored for different purposes, then versatility is improved, but storage space and inventory management become more complex
Solution Approach 1:
A universal plug design with standardized dimensions and attachment mechanisms is created that can serve multiple informational purposes. The same basic plug type can be used for different water types, locations, or informational messages, reducing the total number of different plug varieties needed while maintaining versatility.
Solution Approach 2:
Rather than creating different physical plug types, the system uses parameter changes (color, text, symbols) on a standardized plug form factor. This allows the same plug structure to convey different information by simply changing its visual parameters, reducing inventory complexity while maintaining adaptability.

AI summary
A sprinkler informational plug is provided. The plug includes a cap, a shaft, and a key. The cap includes a plurality of grips disposed about peripheral surface of the cap. The shaft is tapered between the cap and the key. The key includes a first bit and a second bit extending from the key. The plug is configured to be inserted through a cover and to engage a lock plate of the sprinkler to secure the plug to the sprinkler.
