Quick-Connect Waterway Fitting With Audible Leak-Safe Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waterway connections in appliances and plumbing are difficult to disconnect and reconnect, often leading to leaks and consumer dissatisfaction due to improper reassembly, and either lack leak-proof integrity or are too secure for easy disassembly.
Innovation Solution
A quick-connect fitting with a male and female component, secured by a clip that snaps into place with an audible confirmation, allowing easy disconnection and reconnection while maintaining a leak-proof seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If waterway connections are made securely to ensure leak-proof connection, then connection reliability is improved, but disassembly difficulty increases
Solution Approach 1:
The connection system is divided into male and female fittings with distinct functional features. The male fitting has a recess for engagement, while the female fitting has apertures for the clip. This segmentation allows the connection to be secure during operation but easily disassembled by targeting specific components (the clip).
Solution Approach 2:
The clip acts as an intermediary component that mediates between the male and female fittings. It provides the secure locking mechanism for leak-proof connection while also serving as the release mechanism for disassembly. The tab on the clip engages with the recess in the male fitting, creating a controlled engagement that can be easily released.
2Ease of operation
If connection features are designed for easy disconnection, then ease of operation is improved, but connection reliability deteriorates
Solution Approach 1:
The connection system transitions from a static, permanently secure connection to a dynamic system that can easily transition between connected and disconnected states. The clip can be quickly engaged to create a secure connection and just as quickly disengaged to release the connection, providing operational flexibility without compromising connection integrity when engaged.
3Reliability
If connection security is increased to prevent inadvertent loosening, then connection reliability is improved, but consumer ability to disassemble for service deteriorates
Solution Approach 1:
The clip serves as an intermediary that separates the security function from the disassembly function. It provides the necessary security to prevent inadvertent loosening through its locking engagement, while simultaneously serving as the target for intentional disassembly during service. The tab-recess engagement ensures secure connection, but the clip's external accessibility makes it the obvious target for service disassembly.
4Reliability
If prior connections were made securely, then leak-proof performance is improved, but reassembly accuracy deteriorates leading to leaks
Solution Approach 1:
The male and female fittings have asymmetric, complementary features that guide proper alignment during reassembly. The recess in the male fitting and the corresponding engagement features in the female fitting create a unique geometric relationship that ensures correct orientation. This asymmetric design makes it obvious when the components are properly aligned, eliminating the precision problems that plague symmetric connection systems.
