Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If existing thermally insulated packages are used to provide good temperature control, then temperature control characteristics are improved, but cost and complexity increase and multiple use capability is reduced

Engineering Contradiction:
Improvetemperature controlVSAvoidpackage complexity
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The package is divided into modular components: an outer shell, removable inner containers holding PCM panels, and separate insulation layers. This segmentation allows individual components to be replaced, cleaned, or maintained independently, enabling multiple uses while maintaining temperature control functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The inner containers holding PCM panels are designed to be removable and replaceable. After use, the inner containers can be easily removed from the outer shell for cleaning, sterilization, or replacement of PCM panels, allowing the package structure to be reused multiple times while recovering and maintaining the temperature control function.

Inventive Principle:
Principle #34Discarding and recovering

2Temperature

If existing thermally insulated packages are designed for good temperature control, then temperature stability is improved, but compactness and robustness are reduced

Engineering Contradiction:
Improvetemperature stabilityVSAvoidrobustness
Core Design Contradiction:
TemperatureVSStrength

Solution Approach 1:

The outer shell is designed with inherent structural strength and rigidity to protect the internal PCM panels and insulation from mechanical damage during transport and handling. This robust outer structure cushions and protects the more delicate internal components, enabling the package to withstand rough handling while maintaining temperature stability.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

3Temperature

If existing thermally insulated packages provide adequate temperature control, then temperature regulation is improved, but ease of manufacture and cost-effectiveness are reduced

Engineering Contradiction:
Improvetemperature regulationVSAvoidmanufacturing ease
Core Design Contradiction:
TemperatureVSEase of manufacture

Solution Approach 1:

The package is constructed from separate, easily manufactured components: a simple outer shell, standardized inner containers, and off-the-shelf insulation materials. Each component can be manufactured independently using simple processes, then assembled together, reducing overall manufacturing complexity and cost while maintaining effective temperature regulation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The outer shell serves multiple functions: it provides structural support, acts as a thermal barrier, and serves as a protective container. This multi-functionality reduces the number of separate components needed, simplifying manufacturing and reducing costs while maintaining temperature regulation capability.

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