Solution Overview

Problem

The high demand for heat pumps and hybrid systems in the transition to secure and sustainable heating is hindered by the shortage of installers trained in refrigeration system mechatronics, leading to long lead times and installation delays.

Innovation Solution

A method for configuring a hybrid system that includes a first type of heat generator (e.g., heat pump) and a second type of heat generator (e.g., combustion appliance), where a configuration control unit receives information about the configuration status of both types of heat generators and defines the configuration order, allowing for partial installation and operation independent of the availability of heat pumps or certified installers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a heat pump is installed in a hybrid system, then sustainable heating and climate target compliance are improved, but installation complexity and certification requirements increase

Engineering Contradiction:
Improveclimate target complianceVSAvoidinstallation complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The configuration process is segmented into distinct phases: initial system configuration without heat pump, heat pump addition phase, and integration phase. This allows the system to be installed and commissioned in stages, reducing the complexity burden at any single point in time.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The control unit is pre-configured with the capability to manage hybrid systems before the heat pump is physically installed. Configuration data structures and control logic are prepared in advance, so that when the heat pump is added later, the system can seamlessly integrate it without requiring complete reconfiguration or certified refrigeration technicians.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If heat pump installers with refrigeration system mechatronics training are required, then system reliability is improved, but installer availability and installation speed worsen

Engineering Contradiction:
Improvesystem reliabilityVSAvoidinstallation speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The configuration control unit performs self-configuration and automatic detection of heat generator types. The system automatically adapts its control logic based on which heat generators are present, eliminating the need for installers to manually configure complex hybrid parameters or possess specialized refrigeration certification.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The control unit is designed with universal functionality to manage multiple heat generator types (combustion appliance, heat pump, solar thermal) through a single interface and configuration paradigm. This multi-functionality allows any qualified installer to work with any combination of heat generators without requiring type-specific expertise.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Loss of time

If the complete hybrid system is configured before heat pump availability, then project timeline is improved, but configuration accuracy worsens

Engineering Contradiction:
Improveproject timelineVSAvoidconfiguration accuracy
Core Design Contradiction:
Loss of timeVSManufacturing precision

Solution Approach 1:

The system configuration is made dynamic rather than static. The control unit continuously monitors which heat generators are present and automatically adjusts its operational mode and control parameters. This allows the system to be fully configured in the planning phase with placeholder data, then automatically refine its configuration when actual components are installed, maintaining both timeline and accuracy.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The configuration control unit implements feedback mechanisms that detect the actual presence and status of heat generators, then automatically adjust configuration parameters accordingly. This closed-loop approach ensures that even if initial configuration assumptions were incorrect, the system self-corrects when real components are connected, maintaining configuration accuracy without delaying the project.

Inventive Principle:
Principle #23Feedback
