Connector, heating radiator and method for connection of a heating radiator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection parts for radiators are complex and costly due to their need for rotatable components to adjust flow direction, making flexible on-site adaptation difficult and expensive.
Innovation Solution
Designing connection parts with distinct flow and return elements that can be easily inserted into the same connection part, using a screw connection and differentially oriented overflow cross-sections to block fluid flow, eliminating the need for rotatable blocking elements and simplifying manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If rotatable blocking elements are used to adjust flow direction, then flexible on-site adaptation is achieved, but device complexity and production costs increase
Solution Approach 1:
The connection part is divided into separate functional components: a stationary connection body with multiple connection pieces, and separate blocking elements (flow element and return element) that can be independently inserted. This segmentation eliminates the need for complex rotatable mechanisms while maintaining adaptability through simple insertion/removal of blocking elements.
Solution Approach 2:
The blocking function is extracted from a complex rotatable mechanism and implemented through simple, separate blocking elements that can be independently inserted into the connection part. This extraction simplifies the overall device structure while preserving the ability to adapt flow direction on-site.
2Adaptability or versatility
If rotatable blocking elements are used to adjust flow direction, then flexible on-site adaptation is achieved, but production costs increase
Solution Approach 1:
By segmenting the connection part into a stationary body and separate blocking elements, manufacturing becomes simpler and more cost-effective. Each component can be manufactured independently using standard machining processes, avoiding the need for complex rotatable mechanisms.
Solution Approach 2:
The blocking elements are designed as simple, inexpensive components that can be easily manufactured and replaced if needed. This approach uses simple blocking elements rather than expensive rotatable mechanisms, significantly reducing production costs while maintaining adaptability.
3Ease of manufacture
If distinct flow and return elements are used, then manufacturing complexity is reduced, but device assembly requires additional steps
Solution Approach 1:
The blocking elements are designed with predetermined orientations and insertion directions. The flow element and return element are each configured to block specific connection pieces when inserted, eliminating the need for complex assembly procedures. The preliminary design of the blocking elements ensures they automatically assume the correct position upon insertion.

AI summary
The invention relates to a connection part (1, 1) for a radiator (29) for conducting a heating fluid, the connection part (1, 1) having two connecting pieces, at least one connecting piece and a flow element (2) or return element (21), wherein in an assembled state in which the connecting part (1, 1) is inserted with a longitudinal axis coaxial to the at least one connecting piece in the connecting part (1, 1), the connecting piece can be flowed through by the flow element (2) or return element (21). and the flow element (2) or return element (21) blocks a flow connection between only one of the connection pieces and the connection piece, and wherein in a basic state of the connection part (1, 1) in which the flow element (2) and return element (21 ) is not inserted into the connecting part (1, 1), the connecting piece and the connecting piece are fluidically connected to one another through the connecting part (1, 1). In order to produce a connection part in which flexible adjustment of the connection parts at the installation site of the radiator is just as easily possible as in the prior art, but in which case significantly simplified and therefore more cost-effective components can be used, it is proposed according to the invention that the flow element (2) and the return element (21) are rotationally symmetrical about the longitudinal axis and block the flow connection independently of an angular position about the longitudinal axis. The present invention also relates to a heating element (29) with connection parts (1, 1) according to the invention and a method for connecting it.
