Solution Overview

Problem

Existing medicine storage containers made of PP or PET materials lack effective moisture shielding, requiring separate desiccants that complicate the container configuration and pose risks of desiccant leakage and contamination.

Innovation Solution

An eco-friendly container design featuring a detachable inner case made of zeolite material and an outer case made of PET, allowing for easy separation and recycling, while the zeolite inner case absorbs moisture to protect pharmaceuticals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If PP or PET materials are used for storage containers, then manufacturing cost and material availability are improved, but moisture shielding capability deteriorates

Engineering Contradiction:

Improvemanufacturing costVSAvoidmoisture intrusion

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The container is divided into two separate cases: an outer case made of PP/PET material for structural protection and an inner case made of zeolite material for moisture absorption. This segmentation allows each component to be optimized for its specific function while maintaining ease of manufacture through standardized materials.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention combines different materials with complementary properties: PP/PET provides structural integrity and cost-effectiveness, while zeolite provides hygroscopic moisture absorption. This composite material approach resolves the contradiction by assigning different material functions to different components.

Inventive Principle:

Principle #40Composite materials

2Object-affected harmful factors

If a separate desiccant is provided in the container, then moisture protection capability is improved, but device complexity and configuration difficulty worsen

Engineering Contradiction:

Improvemoisture protectionVSAvoidcontainer configuration

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The moisture absorption function is merged into the inner case structure itself through the zeolite material, eliminating the need for separate desiccant components. This integration simplifies the overall container configuration while maintaining effective moisture protection.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The inner case serves multiple functions simultaneously: it contains the pharmaceutical product and provides moisture absorption through its zeolite material. This multi-functionality eliminates the need for separate desiccant components, reducing device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Object-affected harmful factors

If a separate desiccant is provided in the container, then moisture protection capability is improved, but reliability and contamination risk worsen

Engineering Contradiction:

Improvemoisture protectionVSAvoiddesiccant leakage risk

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

By integrating moisture absorption into the inner case structure through zeolite material, the invention eliminates the separate desiccant component that could leak or contaminate. The moisture protection function is built-in, improving reliability.

Inventive Principle:

Principle #5Merging (Combining)

4Object-affected harmful factors

If a separate desiccant is provided in the container, then moisture protection capability is improved, but ease of recycling and disposal worsens

Engineering Contradiction:

Improvemoisture protectionVSAvoidrecycling separation

Core Design Contradiction:

Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The container is segmented into clearly defined outer and inner cases that can be easily separated. This segmentation, combined with the integration of moisture absorption into the inner case, simplifies the recycling process by eliminating separate desiccant components to sort and separate recyclable materials from non-recyclables.

Inventive Principle:

Principle #1Segmentation
