Solution Overview

Problem

Existing disposable plastic bags take decades to decompose, causing pollution, while reusable cloth bags are often forgotten at home, leading to accumulation and ineffective use.

Innovation Solution

A disposable biodegradable bag made from sheets of biodegradable material, such as biodegradable dryer sheets, which are stitched together to form a bag that can be used once and disposed of without causing pollution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If disposable plastic bags are used, then convenience is improved, but environmental pollution worsens due to decades-long decomposition time

Engineering Contradiction:

ImproveconvenienceVSAvoidenvironmental pollution

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent changes the material parameter from conventional plastic to biodegradable materials (paper, fabric, bioplastics), fundamentally altering the decomposition time parameter from decades to weeks or months, thereby resolving the environmental pollution issue while maintaining the disposable convenience

Inventive Principle:

Principle #35Parameter changes

2Object-affected harmful factors

If reusable cloth bags are used, then environmental pollution is reduced, but ease of operation worsens due to the need to remember and transport them

Engineering Contradiction:

Improveenvironmental pollutionVSAvoidconvenience

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The patent applies the disposable principle by creating bags that are intentionally designed for single-use or limited-use scenarios. These biodegradable disposable bags eliminate the need for users to remember and transport reusable bags, while still being environmentally friendly due to their rapid decomposition capability

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Object-affected harmful factors

If biodegradable materials are used, then environmental pollution is reduced through easy decomposition, but manufacturing complexity increases

Engineering Contradiction:

Improveenvironmental pollutionVSAvoidmanufacturing complexity

Core Design Contradiction:

Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The patent segments the manufacturing process into simple, modular steps: providing individual biodegradable sheets and coupling them together to form bags. This segmentation simplifies the overall manufacturing complexity by breaking down the process into manageable, independent operations that can be performed with basic equipment

Inventive Principle:

Principle #1Segmentation

AI summary

A method for manufacturing a disposable biodegradable bag for carrying items then discarding the bag without creating unwanted pollution includes providing a first rectangular sheet of biodegradable material having a first top edge, a first bottom edge, and a first pair of lateral side edges. The first rectangular sheet of biodegradable material may be a first biodegradable dryer sheet. The method further includes providing a second rectangular sheet of biodegradable material having a second top edge, a second bottom edge, and a second pair of lateral side edges. The second rectangular sheet of biodegradable material may be a second biodegradable dryer sheet. The method further includes coupling the first bottom edge to the second bottom edge and coupling the first pair of lateral side edges to the second pair of lateral side edges to form a bag having an opening between the first top edge and the second top edge.
