Swivel Radiator Coupling With Sliding Bushing Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing swivel-type coupling devices for domestic radiators are complex and time-consuming to assemble due to the requirement of connecting tubular male and female members before attaching them to the heating fluid conveying conduits, necessitating additional welding operations.
Innovation Solution
A swivel-type coupling device featuring cup-shaped members with an axial bore, a bushing with a radially inward flange, and a resilient element that allows axial sliding and fluid-tight sealing, enabling coaxial arrangement and assembly without subsequent welding by using a bushing with elastomeric seals and a resilient member for centering and fluid flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If tubular male and female coupling members are connected together before attaching to heating fluid conveying conduits, then fluid-tight sealing is maintained, but assembly time and complexity increase due to additional welding operations
Solution Approach 1:
The coupling device is divided into separate cup-shaped members that can be independently attached to the heating fluid conveying conduits. The first cup-shaped member attaches to one conduit while the second cup-shaped member attaches to another conduit, allowing parallel assembly operations instead of sequential connection of male and female members followed by conduit attachment.
Solution Approach 2:
The cup-shaped members are designed with pre-formed sealing surfaces and sealing elements that are already in place before assembly. This preliminary preparation of sealing components allows the members to be directly attached to the conduits without requiring additional welding operations to establish fluid-tight connections.
2Adaptability or versatility
If tubular male and female coupling members are used with connecting ring, then relative rotation between conduits is enabled, but device complexity increases requiring multiple separate operations
Solution Approach 1:
The cup-shaped members integrate multiple functions into single components. Each cup-shaped member combines the functions of coupling, sealing, and rotation enablement in one piece that attaches directly to the conduit, eliminating the need for separate connecting rings and multiple assembly operations required by traditional male-female coupling designs.

AI summary
The invention relates to a swivel -type coupling device (10) enabling relative rotation between heating fluid conveying conduits of a domestic heating radiator unit connected thereto. The swivel -type coupling device comprises: a first cup- shaped member (11) having an axial bore extending therethrough and being connectable to a first heating fluid conveying conduit, a second cup- shaped member (12) having an axial bore extending therethrough and being connectable to a second heating fluid conveying conduit. The cup -shaped members are coaxially arranged with their hollow portions facing one another, in order to form an axial cavity which communicates with heating fluid conveying conduits. A bushing (14) is arranged to slide axially within the axial cavity and is capable of providing a fluid- tight seal of the axial cavity. A resilient element (17) is interposed between the bushing and the first cup -shaped member of the coupling device.
