Solution Overview

Problem

Conventional heating systems require significant space and installation due to separate components and lack of alternative heat sources, leading to increased costs and inefficiencies, especially in low-energy houses.

Innovation Solution

A compact heating center integrating a condensing boiler as a conventional heat source and an internal heat pump as a renewable energy source, eliminating the need for a separate buffer storage tank by using the boiler body for heat storage, and incorporating a secondary heat exchanger for efficient energy transfer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If separate buffer storage tank and individual heating components are used, then heating system functionality is ensured, but space requirements and installation complexity increase

Engineering Contradiction:
Improvespace requirementsVSAvoidinstallation complexity
Core Design Contradiction:
Volume of moving objectVSDevice complexity

Solution Approach 1:

The patent combines the buffer storage tank, condensing boiler, and heat pump into a single integrated heating center unit. This merging of previously separate components reduces the overall space requirements and simplifies installation while maintaining all necessary heating functions.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The heating center is designed as a multi-functional unit that can operate in different modes (heating, cooling, buffer storage) using a single integrated system. The unit can function as a condensing boiler, heat pump, or buffer tank depending on operational requirements, eliminating the need for separate dedicated components.

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

2Reliability

If conventional heating systems with separate components are installed, then reliable heating is provided, but installation costs and time increase

Engineering Contradiction:
Improveheating reliabilityVSAvoidinstallation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The heating center is pre-assembled and pre-tested as a complete integrated unit before delivery to the installation site. This preliminary preparation of the system allows for rapid installation by simply connecting the pre-assembled unit to existing infrastructure, significantly reducing on-site installation time while ensuring reliability through factory testing.

Inventive Principle:
Principle #10Preliminary action

3Quantity of substance

If separate buffer storage tank is used, then heat storage capacity is ensured, but space and installation costs increase

Engineering Contradiction:
Improveheat storage capacityVSAvoidinstallation area
Core Design Contradiction:
Quantity of substanceVSArea of stationary object

Solution Approach 1:

The buffer storage functionality is integrated into the heating center by incorporating a buffer tank as an internal component rather than a separate external installation. This merging eliminates the need for additional installation area while maintaining the necessary heat storage capacity through the integrated tank design.

Inventive Principle:
Principle #5Merging (Combining)
