Solution Overview

Problem

Conventional insulating packaging for temperature-sensitive products, such as perishable food and medicines, often requires additional insulating materials like Styrofoam, which is not always desirable due to environmental concerns and logistical challenges.

Innovation Solution

A metal-coated insulating packaging made from paper or cardboard materials, featuring a multi-layered structure with a silver paste coating for enhanced thermal insulation, allowing for effective temperature regulation without the need for additional insulating materials.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If additional insulating material like Styrofoam is introduced into the packaging, then thermal insulation is improved, but device complexity and environmental harm increase

Engineering Contradiction:
Improvethermal insulationVSAvoidpackaging structure
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The patent applies parameter changes by modifying the surface properties of the packaging material through metal coating. The coating changes the thermal radiation characteristics of the packaging surface, enabling it to reflect thermal radiation and achieve insulation effects without adding bulky insulating materials like Styrofoam.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent uses composite materials by combining paper or cardboard base material with a metal coating layer. This composite structure maintains the advantages of the base material (lightweight, formable) while adding the thermal radiation reflection properties of the metal coating, achieving insulation without the complexity of multi-layer foam structures.

Inventive Principle:
Principle #40Composite materials

2Temperature

If additional insulating material like Styrofoam is introduced into the packaging, then thermal insulation is improved, but environmental harm increases

Engineering Contradiction:
Improvethermal insulationVSAvoidenvironmental harm
Core Design Contradiction:
TemperatureVSObject-affected harmful factors

Solution Approach 1:

The patent employs disposable paper or cardboard packaging with metal coating instead of reusable or hard-to-recycle Styrofoam. The coated packaging maintains insulation performance for the required transport duration and can be easily disposed of or recycled, reducing environmental persistence and pollution compared to traditional foam materials.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The patent replaces mechanical insulating structures (thick foam layers) with a surface coating system that achieves insulation through optical properties (thermal radiation reflection). This substitution eliminates the need for bulky mechanical insulation while reducing material waste and environmental impact.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Temperature

If metal coating is applied to the packaging, then thermal radiation reflection is improved, but manufacturing complexity increases

Engineering Contradiction:
Improvethermal radiation reflectionVSAvoidcoating application
Core Design Contradiction:
