Solution Overview

Problem

Existing heat exchanger designs for motor vehicle air conditioning systems lack flexibility in adapting to different installation conditions within vehicles, as they rely on fixed soldered connections that do not easily accommodate varying installation requirements.

Innovation Solution

A flexible strip holder system is introduced, where a strip is indirectly attached to the header via a connection flange and intermediate bracket, both soldered to the manifold, allowing for adjustable attachment points and variable length configurations, enabling self-fixing without additional tools during the soldering process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed holder design is used for the heat exchanger, then the manufacturing process is simple, but the adaptability to different installation conditions in vehicles is poor

Engineering Contradiction:
Improveadaptability to installation conditionsVSAvoidholder structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The holder strip is designed with a variable length that can be adjusted during installation. The strip can be cut to different lengths depending on the specific installation requirements in different vehicles, transforming a static fixed-length design into a dynamic adjustable-length design, thereby improving adaptability without significantly increasing structural complexity

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The holder system is divided into multiple components: the holder strip, connection flange, and intermediate bracket. This segmentation allows each component to be independently optimized and assembled in different configurations to suit various installation conditions, enhancing versatility while maintaining manageable complexity

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If multiple separate components are used for holder and connection flange, then the positioning flexibility is improved, but the number of soldering connections and tools required increases

Engineering Contradiction:
Improveease of solderingVSAvoidnumber of components
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The connection flange and intermediate bracket are designed to be combined into a single integrated component. This merging eliminates the need for a separate soldering connection between the holder strip and the collecting tube, reducing the number of soldering operations from three to two, and eliminating the need for additional clamping devices during soldering, thereby improving ease of operation

Inventive Principle:
Principle #5Merging (Combining)

3Stability of the object's composition

If the holder strip is directly soldered to the header pipe, then the connection is stable, but the positioning flexibility and adaptability to different installation points is reduced

Engineering Contradiction:
Improveattachment stabilityVSAvoidattachment point flexibility
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The connection flange and intermediate bracket serve as intermediary components between the holder strip and the collecting tube. These intermediaries provide standardized soldering connection points while allowing the holder strip to be positioned at various locations along its length, thus maintaining attachment stability through reliable soldered connections while enabling positioning flexibility for different installation requirements

Inventive Principle:
Principle #24Intermediary (Mediator)
