Solution Overview

Problem

Existing capacitor assemblies for air conditioning systems, particularly in motor vehicles, face structural and thermodynamic limitations that restrict installation space and increase material usage, complicating the manufacturing and soldering processes.

Innovation Solution

A capacitor assembly design where the inlet and outlet openings are arranged on the same side of the tubes, allowing for fluid communication with the headers, reducing installation space constraints and enabling more flexible thermodynamic design, while also simplifying the manufacturing process and reducing material usage by integrating the inlet and outlet with the collection container or first collecting tube.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If the inlet and outlet openings are arranged on opposite sides of the tubes (conventional design), then the structural stability is improved, but the installation space requirements increase and design freedom is reduced

Engineering Contradiction:
Improveinstallation spaceVSAvoidstructural complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The patent applies dimensionality change by arranging both inlet and outlet openings on the same side of the condenser assembly (first header) rather than on opposite sides. This reconfigures the spatial arrangement from a linear/opposite configuration to a lateral/same-side configuration, freeing up the opposite side for alternative uses such as mounting brackets or additional components, thereby reducing installation space requirements while maintaining structural integrity

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The first header is designed to serve multiple functions: it acts as both the inlet header and outlet header for the refrigerant flow, and simultaneously provides mounting surfaces for both inlet and outlet openings. This multi-functionality reduces the need for separate dedicated headers for each function, simplifying the overall structure and reducing installation space requirements

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

2Loss of substance

If separate headers are used for inlet and outlet, then the fluid flow control is improved, but the material usage increases and manufacturing complexity increases

Engineering Contradiction:
Improvematerial usageVSAvoidmanufacturing process
Core Design Contradiction:
Loss of substanceVSEase of manufacture

Solution Approach 1:

The patent merges the inlet header and outlet header functions into a single first header component. Both the inlet opening and outlet opening are provided on the same first header, eliminating the need for a separate second header for outlet purposes. This consolidation reduces material usage by removing redundant header structure while simplifying the manufacturing process by reducing the number of components that need to be produced, assembled, and soldered

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If the inlet and outlet are arranged on the same side, then the installation freedom is improved, but the thermodynamic flow path optimization may be compromised

Engineering Contradiction:
Improvedesign freedomVSAvoidflow path precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent employs dynamic flow management within the single header by providing multiple inlet openings and multiple outlet openings that can be selectively activated or deactivated based on operating conditions. The header internal geometry is designed to dynamically distribute refrigerant flow across multiple tubes, ensuring optimal thermodynamic performance is maintained regardless of which specific inlet/outlet combinations are in use, thus preserving flow path precision while achieving design freedom

Inventive Principle:
Principle #15Dynamics
