Solution Overview

Problem

The existing packaging solutions, such as plastic bags, are no longer authorized due to environmental regulations, and reusable alternatives like paper bags are not always practical for bulk shopping, necessitating a more efficient and hygienic option that conserves natural resources.

Innovation Solution

A kit of 6 reusable packaging bags made of 100% polyester, designed with specific dimensions, handles, and a compact storage system, allowing easy handling and maintenance, while being adaptable for various uses.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If plastic bags are used for bulk fruit and vegetables, then packaging functionality is provided, but environmental regulations prohibit their use

Engineering Contradiction:
Improvepackaging functionalityVSAvoidenvironmental harm
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the material parameter from plastic to 100% polyester, transforming the packaging bag to meet environmental regulations while maintaining its functionality for bulk fruit and vegetable packaging. This material substitution resolves the contradiction between providing packaging functionality and avoiding environmental harm.

Inventive Principle:
Principle #35Parameter changes

2Object-affected harmful factors

If paper bags are used as alternative to plastic bags, then environmental harm is reduced, but hygiene and practicality for bulk shopping are insufficient

Engineering Contradiction:
Improveenvironmental harmVSAvoidhygiene and durability
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent changes the material parameter from paper to 100% polyester, which provides both environmental benefits (reducing harm) and superior performance characteristics (hygiene and durability) needed for bulk shopping. The polyester material resists degradation and maintains cleanliness better than paper.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent uses 100% polyester material that combines the environmental advantages of reusable packaging with the practical benefits of durability and hygiene, creating a composite solution that satisfies both ecological and functional requirements.

Inventive Principle:
Principle #40Composite materials

3Loss of substance

If reusable bags are introduced to save natural resources, then environmental sustainability is improved, but device complexity and storage requirements increase

Engineering Contradiction:
Improvenatural resource consumptionVSAvoidstorage system complexity
Core Design Contradiction:
Loss of substanceVSDevice complexity

Solution Approach 1:

The patent implements a nested storage system where six individual polyester bags are compacted and stored within a single reusable cover. The bags are arranged in a compact configuration that fits neatly inside the cover, reducing storage space requirements while maintaining reusability and environmental benefits.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent combines multiple individual bags (six total) into a single integrated kit stored within one cover. This merging reduces the overall complexity of storage and handling, allowing users to carry and store the entire set in a single compact unit rather than managing six separate bags.

Inventive Principle:
Principle #5Merging (Combining)

4Reliability

If 100% polyester material is used, then label adhesion and hygiene are improved, but manufacturing cost increases

Engineering Contradiction:
Improvelabel adhesion and hygieneVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent specifies a weight parameter for the polyester material (30-60 g per m²) that optimizes the balance between cost and performance. This parameter range ensures adequate label adhesion and hygiene properties while controlling manufacturing costs, making the solution economically viable.

Inventive Principle:
Principle #35Parameter changes
