Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing couplings for fluid systems, such as irrigation systems, require time-consuming and messy processes like primer and glue application or threaded attachments, leading to unreliable connections and increased installation time.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If primer and glue are used to attach conduits, then a fluid-tight seal can be achieved, but the installation process becomes time-consuming and messy
Solution Approach 1:
The patent replaces the chemical bonding system (primer and glue) with a mechanical retention system consisting of a coupling device with internal gripping features. The coupling uses a retention mechanism with teeth or ridges that mechanically engage with the conduit surface, eliminating the need for chemical adhesives and significantly reducing installation time while maintaining connection reliability
Solution Approach 2:
The coupling device is divided into distinct functional components: an external coupling portion that interfaces with the conduit, an internal coupling portion that connects to system components, and a retention mechanism with gripping features. This segmentation allows each component to perform its specific function efficiently, with the retention mechanism providing secure mechanical attachment without chemical substances
2Productivity
If threaded or barbed fittings are used to attach conduits, then connection speed improves, but the connection integrity becomes uncertain
Solution Approach 1:
The coupling device incorporates localized gripping features (teeth or ridges) at specific positions within the coupling body that concentrate mechanical engagement forces. These localized features create high-contact-area points that securely grip the conduit without requiring threading or barbing, thus maintaining connection integrity while preserving installation speed
Solution Approach 2:
The coupling device may utilize composite construction combining rigid structural portions for strength with elastomeric or flexible gripping surfaces that conform to and securely hold the conduit. This composite approach ensures both rapid installation and reliable connection integrity by combining the advantages of different material properties
3Ease of manufacture
If known couplings are used to attach irrigation components, then assembly can be achieved, but installation time increases significantly
Solution Approach 1:
The coupling device merges multiple functions into a single integrated component: fluid-tight sealing, mechanical retention, and component alignment are all achieved through one coupling device rather than requiring separate fittings, adhesives, or fasteners. This consolidation maintains assembly capability while dramatically reducing installation time by eliminating multiple steps
Solution Approach 2:
The coupling device is pre-configured with internal gripping features and sealing elements during manufacturing, so that during installation, the conduit simply needs to be inserted into the coupling. The retention mechanism is already in place to provide immediate mechanical engagement, eliminating the need for on-site assembly of multiple components or application of adhesives

AI summary
A coupling may be configured to receive and secure an insertion end of a conduit. An outer surface of the insertion end of the conduit may be smooth and free of grooves, flanges and beads. A first member of the coupling may define a first passageway. A second member of the coupling may define a second passageway. The first member may be in spin weld engagement with the second member. A gripping ring having an inner edge defining a series of teeth may be disposed within the second member. A support ring and O-ring may also be disposed within the second member.
