Solution Overview

Problem

Existing heating and air conditioning installations that use decoupling bottles for hydraulic independence are costly, large, time-consuming to assemble, and prone to leakage due to the number of hydraulic connections required.

Innovation Solution

A compact heat transfer module with a decoupling bottle directly connected to a heat exchange device, featuring a pump integrated within the decoupling bottle, a bent pipe to manage fluid flow, and a thermoplastic material with low thermal conductivity, reducing the need for extensive pipework and minimizing size while ensuring hydraulic decoupling and efficient fluid circulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a decoupling bottle is used to achieve hydraulic independence between primary and secondary loops, then hydraulic independence is achieved, but the installation cost increases due to additional parts and hydraulic connections

Engineering Contradiction:
Improvehydraulic independenceVSAvoidnumber of parts and connections
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the decoupling bottle with the heat exchange device into a single integrated unit. The decoupling bottle is positioned inside the heat exchange device housing, and both components share common hydraulic connections. This integration eliminates the need for separate decoupling bottle connections to the heat exchange device, reducing the total number of hydraulic connections and parts while maintaining hydraulic independence between primary and secondary loops.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If a decoupling bottle is used to achieve hydraulic independence, then hydraulic independence is achieved, but the installation size increases

Engineering Contradiction:
Improvehydraulic independenceVSAvoidinstallation size
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The patent implements nesting by placing the decoupling bottle inside the heat exchange device housing. The decoupling bottle occupies internal space within the existing heat exchange device structure rather than requiring separate external space. This nested arrangement allows both the heat exchange device and decoupling bottle to coexist in a compact configuration, reducing the overall installation footprint while maintaining the hydraulic independence function.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Reliability

If multiple hydraulic connections are used for the decoupling bottle, then hydraulic independence is achieved, but assembly time increases

Engineering Contradiction:
Improvehydraulic independenceVSAvoidassembly time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent merges the hydraulic connection points of the decoupling bottle with those of the heat exchange device. The decoupling bottle's inlet and outlet connections are aligned with and integrated into the heat exchange device's connection points, allowing both components to share the same hydraulic interfaces. This integration reduces the number of separate connection operations required during assembly, thereby reducing assembly time while maintaining hydraulic independence.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The module (30) has a heat exchange device (32) including a cold water inlet (34) and a hot water outlet (36). A decoupling bottle (44) includes a hot water inlet (46), a cold water inlet, a hot water outlet and a cold water outlet (52). The bottle hydraulically decouples the water flow between the hot water outlet and the hot water inlet, and the water flow between the cold water outlet and the cold water inlet. The hot water inlet and the cold water outlet of the bottle are connected directly to the hot water outlet and the cold water inlet of the heat exchange device. An independent claim is also included for a thermal control installation of water.
