Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If heat pump systems are manufactured with individual assembly and complex configurations to offer a wide variety of models, then design diversity and customer customization are improved, but manufacturing effort, packaging complexity, and assembly time increase significantly

Engineering Contradiction:
Improvedesign diversityVSAvoidassembly complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The heat pump system is divided into modular components (compressor module, evaporator module, condenser module, control module) that can be independently manufactured and then assembled. This segmentation allows standardization of each module while enabling flexible combinations to create diverse system configurations, thereby reducing overall assembly complexity and manufacturing effort.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If heat pump systems are manufactured with individual assembly and complex configurations to offer a wide variety of models, then design diversity and customer customization are improved, but packaging effort and service complexity increase significantly

Engineering Contradiction:
Improvedesign diversityVSAvoidpackaging effort
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

By segmenting the system into standardized modules, each module can be packaged separately in uniform containers. This reduces packaging complexity compared to custom-packaging entire assembled systems, while still allowing diverse configurations to be created from the same set of packaged modules.

Inventive Principle:
Principle #1Segmentation

3Productivity

If heat pump systems use modular design with standardized connections, then manufacturing effort and assembly time are reduced, but the ability to offer diverse configurations may be limited

Engineering Contradiction:
Improveassembly speedVSAvoidconfiguration variety
Core Design Contradiction:

Solution Approach 1:

The modular components are designed with universal interfaces and standardized connections that can accommodate multiple configuration types. For example, the compressor module can be universally connected to different evaporator and condenser modules, allowing rapid assembly of various system configurations while maintaining assembly efficiency.

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

AI summary

The invention relates to a modular heat pump system, which has, as module types, a refrigeration circuit module (8), a hydraulic module (10), a hot water module (12), and optionally a heat source module (22), in particular for a split installation. For each module type, a plurality of module variants, in particular of different power classes, can be assembled by suitably combining the individual components. By combining the module types (8, 10, 12, 22), different module variants and different heat pump types or heat pumps of the same type having different power can be assembled in a simple manner. The planning complexity and production complexity are kept low by this modular design.
