Solution Overview

Problem

The installation of heating systems with pressure-maintaining and/or degassing devices is complex and prone to errors due to the requirement for maintaining a specific distance between two heating medium flow paths, leading to increased costs and potential hydraulic disruptions.

Innovation Solution

A connection unit with two separate, spaced-apart lines for the pressure-maintaining and/or degassing device and a coaxial line for the heating circuit distributor, where the inner line of the coaxial line protrudes beyond the outer line, simplifying the connection process and ensuring the required hydraulic distance is maintained without the need for multiple connections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If two spaced-apart T-pieces are used to connect the heating medium flow paths to the heating system, then the required distance between connection points is maintained, but installation complexity increases and installation errors may occur

Engineering Contradiction:
Improvedistance between connection pointsVSAvoidinstallation complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent combines two separate connection operations into a single coaxial connection unit. The first line connection and second line connection are merged into one integrated component that connects to the heating circuit distributor via a single coaxial interface, eliminating the need for two separate T-pieces and reducing installation steps while maintaining the required hydraulic distance through the protruding inner line design

Inventive Principle:
Principle #5Merging (Combining)

2Manufacturing precision

If two spaced-apart T-pieces are used for connection, then the connection points are at the required distance, but the risk of installation errors increases

Engineering Contradiction:
Improvedistance between connection pointsVSAvoidinstallation error risk
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

The connection unit is pre-configured with the inner line protruding beyond the outer line by the required distance before installation. This preliminary arrangement of the hydraulic path ensures that when the unit is installed as a single component, the correct hydraulic distance is automatically maintained, eliminating installation errors related to spacing

Inventive Principle:
Principle #10Preliminary action

3Manufacturing precision

If two additional connecting pieces are used on the heating circuit distributor, then the connection points are sufficiently distant, but production complexity and cost increase

Engineering Contradiction:
Improvedistance between connection pointsVSAvoidproduction complexity
Core Design Contradiction:
Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The patent merges the functionality of two separate connecting pieces into a single integrated connection unit. The first line connection and second line connection are combined into one component with a single coaxial interface, simplifying the manufacturing process and reducing production costs while maintaining the required distance through the protruding inner line configuration

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The present invention relates to a connection unit (1) for fluidically connecting a pressure-maintaining and/or degassing device to a heating circuit distributor (2) of a heating system, a first heating medium flow path from the heating circuit distributor (2) via a pressure-dependent switching valve to the pressure-maintaining and/or degassing device and a second heating medium flow path leads from the pressure maintenance and/or degassing device to the heating circuit distributor (2) via a pump that can be switched on and off depending on the pressure. The connection unit (1) according to the invention is characterized in that on the side of the pressure-maintaining and/or degassing device for the two heating medium flow paths it has two separate, spaced-apart lines (11, 12), each with a matching counter-line connection for the pressure-maintaining and /or degassing device connectable line connection (11 ', 12') that on the side of the heating circuit distributor (2) for the two heating medium flow paths a coaxial line (13) with a single connection (13 '), which is connected to a matching mating connection ( 23) can be connected to the heating circuit distributor (2), and that the inner line (13.1) of the coaxial line (13) protrudes beyond an end of the outer line (13.2) of the coaxial line (13) on the distributor side. The invention also relates to a heating circuit distributor (2) and a heating system with such a connection unit (1).
