Reusable Polyester Bag Kit for Bulk Shopping
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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
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.
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.
3Loss of substance
If reusable bags are introduced to save natural resources, then environmental sustainability is improved, but device complexity and storage requirements increase
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.
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.
4Reliability
If 100% polyester material is used, then label adhesion and hygiene are improved, but manufacturing cost increases
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.
