Solution Overview

Problem

Climatization containers face challenges with condensation buildup and pressure differences leading to difficulty in opening doors due to rapid temperature changes, which existing solutions do not adequately address.

Innovation Solution

A valve assembly integrating an air pressure relief valve and a drain valve within a single body portion to manage air and liquid flow, allowing air pressure equalization and waste liquid drainage, thereby reducing the size and improving thermal efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate air pressure relief valve and drain valve are provided, then reliability is improved, but device complexity increases

Engineering Contradiction:
Improvevalve function reliabilityVSAvoidvalve assembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the air pressure relief valve and drain valve into a single integrated valve assembly with a common body portion. This merging approach maintains the functional reliability of both valves while reducing device complexity by eliminating the need for separate valve installations and reducing the number of components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The valve assembly is designed as a multi-functional component where a single body portion houses both the air pressure relief valve and drain valve. This universal design allows one component to perform multiple functions (pressure relief and liquid drainage) that would traditionally require separate components, thereby improving reliability without increasing complexity.

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

2Reliability

If separate air pressure relief valve and drain valve are provided, then functional reliability is improved, but manufacturing cost increases

Engineering Contradiction:
Improvevalve function reliabilityVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

By merging the air pressure relief valve and drain valve into a single integrated assembly, the patent reduces manufacturing costs through economies of scale, simplified production processes, and reduced inventory requirements, while maintaining the functional reliability of both valve functions.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The multi-functional valve assembly allows manufacturers to produce a single component that performs multiple functions, reducing overall manufacturing complexity and cost compared to producing and assembling separate valves, while ensuring both functions remain reliable.

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

3Adaptability or versatility

If multiple separate valves are installed, then functional completeness is improved, but thermal efficiency deteriorates

Engineering Contradiction:
Improvevalve function completenessVSAvoidthermal efficiency
Core Design Contradiction:
Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The patent merges multiple valve functions into a single integrated assembly with a common body portion, reducing the number of penetration points through the container wall. This consolidation maintains functional completeness while improving thermal efficiency by minimizing insulation breaches and reducing heat transfer pathways.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The universal valve assembly design provides complete valve functionality (both air pressure relief and liquid drainage) through a single component that penetrates the container wall at one location, thereby maintaining adaptability and versatility while reducing energy loss compared to multiple separate valves.

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

4Volume of moving object

If valve assembly size is reduced, then interior volume is maximized, but manufacturing complexity increases

Engineering Contradiction:
Improvecontainer interior volumeVSAvoidvalve assembly integration complexity
Core Design Contradiction:
Volume of moving objectVSDevice complexity

Solution Approach 1:

The patent achieves size reduction by merging the air pressure relief valve and drain valve into a single integrated assembly, which maximizes the container interior volume. The integration complexity is managed through modular design and standardized manufacturing processes.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The compact multi-functional valve assembly provides complete valve functionality in a reduced size, maximizing interior volume. The design balances integration complexity with manufacturing feasibility through careful component arrangement and standardized production methods.

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