Solution Overview

Problem

The development of electric vehicles has increased the need for optimized air conditioning and heat pump systems with simplified and economical manufacturing processes, while requiring space-saving thermal management systems that are not effectively addressed by existing technologies.

Innovation Solution

A refrigerant module for thermal management systems is proposed, comprising a compressor directly connected to a first refrigerant unit with channels for distributing refrigerant fluid, and a second refrigerant unit, where the compressor and both units are fluidly connected, allowing for compact design and easy handling, with optional incline and decoupling elements for reduced vibrations and improved installation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the compressor and refrigerant units are separately connected with multiple conduits, then the system has flexibility in installation, but the system occupies more space and has higher manufacturing complexity

Engineering Contradiction:
Improvesystem volumeVSAvoidmanufacturing complexity
Core Design Contradiction:
Volume of moving objectVSDevice complexity

Solution Approach 1:

The patent merges the compressor and multiple refrigerant units into a single integrated refrigerant module where the compressor is directly fluidly connected to the first and second refrigerant units. This consolidation eliminates the need for separate conduits and multiple connection points, reducing overall system volume while simplifying manufacturing processes.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The refrigerant module serves multiple functions within a single integrated structure: the compressor provides refrigerant compression, while the integrated refrigerant units handle both cooling and heating operations. This multi-functionality reduces the need for separate components and conduits, thereby reducing system volume and manufacturing complexity.

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

2Ease of operation

If the compressor and refrigerant units are integrated into one module, then the system is compact and easy to handle, but the vibrations from the compressor may affect system stability

Engineering Contradiction:
Improveease of handlingVSAvoidvibrations
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a bracket as an intermediary component that mechanically connects the compressor to the refrigerant units while providing vibration isolation. This bracket acts as a mediator that transmits necessary mechanical support while filtering out harmful vibrations, allowing the integrated module to remain compact and easy to handle without compromising stability.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If multiple conduits are used to connect compressor to refrigerant units, then the system has redundant fluid paths, but the material consumption and manufacturing cost increase

Engineering Contradiction:
Improvefluid path redundancyVSAvoidmaterial consumption
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The patent combines multiple refrigerant units and their associated conduits into a single integrated refrigerant module. The first and second refrigerant units are directly fluidly connected to the compressor within the module, eliminating the need for separate external conduits and reducing material consumption while maintaining reliable fluid paths.

Inventive Principle:
Principle #5Merging (Combining)
