Steam Iron Quick Connector With Automatic Locking Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for connecting a steam pipe to a solenoid valve in steam-generating appliances require significant effort and time, often leading to musculoskeletal disorders due to limited accessibility during assembly, and existing quick connectors are either bulky or unsuitable for this specific application.
Innovation Solution
A quick connector with a body and head that automatically locks, featuring an elastic clip with transverse branches that engage in a groove, reducing assembly time and effort, and providing secure and audible/visual confirmation of locking, while allowing easy disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If force-fitting the steam pipe onto the connection tube and using pliers to place a clamp, then the connection is secure, but the assembly operation requires a great deal of time and effort
Solution Approach 1:
The connector is divided into two separate parts: a body that is integral with the steam pipe and a head that is carried by the solenoid valve. This segmentation allows each part to be independently manufactured and assembled, enabling quick connection without complex tools or procedures.
Solution Approach 2:
The elastic clip automatically engages with the groove on the head when the head is inserted into the body, creating self-locking functionality. This eliminates the need for manual clamping or additional securing operations, allowing the connection to secure itself automatically.
2Reliability
If force-fitting the steam pipe onto the connection tube and using pliers to place a clamp, then the connection is secure, but the operation generates musculoskeletal disorders due to limited accessibility
Solution Approach 1:
By separating the connector into body and head components, the design eliminates the need for difficult force-fitting operations and manual clamping with pliers, reducing physical strain and accessibility requirements during assembly.
Solution Approach 2:
The automatic locking mechanism through elastic clip engagement eliminates the need for manual clamping operations, reducing physical effort and eliminating the risk of musculoskeletal disorders associated with using pliers in confined spaces.
3Extent of automation
If using a quick connector with elastic clip and groove engagement, then assembly is simplified and automated, but the connector must be compact and suitable for steam applications
Solution Approach 1:
The connector is segmented into body and head parts, each with simple geometries that are easy to manufacture. The body contains a cavity and channel, while the head has a groove, creating a straightforward automatic locking mechanism through elastic clip engagement.
Solution Approach 2:
The elastic clip is designed with specific local properties (elasticity) to provide automatic locking functionality. The groove on the head and cavity in the body are strategically positioned to enable simple yet effective engagement, maintaining compactness while achieving automation.

AI summary
The apparatus has a steam generating base connected to a steam iron by a cord. The cord comprises a steam conduit (20) for transporting steam. The conduit is connected to the base by a quick connector. The quick connector comprises a head (6) axially retained in a cavity of a body (5), and an automatic locking unit for locking the head at a locking position in which the head is sealingly connected to the body. The head is carried by a solenoid valve (4) that is fixed to a vessel for generation of steam under pressure. The locking unit comprises an elastic fastener (7) carried by the body.
