Changeable Bag Modular Coupling System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bags are not adaptable to changing types, shapes, or colors, which limits their versatility in a society where personal expression is important.
Innovation Solution
A changeable bag design comprising a first bag body, a second bag body, and a coupling portion that allows for detachable coupling of the first bag body into the second bag body, enabling various configurations such as different types, shapes, and colors through bottom, narrow side, and wide side coupling mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a bag is manufactured with fixed type, shape, and color, then the manufacturing process is simple and cost-effective, but the bag cannot be changed depending on personal taste or style preferences
Solution Approach 1:
The bag is divided into separate modular components including a first bag body, a second bag body, and independent coupling portions. These segments can be detached and reconfigured to create different bag styles and configurations, allowing users to change the bag's appearance and function without manufacturing entirely new bags.
Solution Approach 2:
The first bag body is designed to be accommodated within the second bag body, creating a nested structure. The coupling portion enables this nested configuration while also allowing the bags to be separated or reconfigured in different arrangements, providing multiple usage modes from a single set of components.
2Adaptability or versatility
If a bag is designed as a single fixed configuration, then the structure is simple and durable, but the bag lacks versatility for different occasions and personal expressions
Solution Approach 1:
The coupling portion is designed to be detachable and reconfigurable, transforming the bag from a static fixed configuration to a dynamic system that can be easily assembled, disassembled, and reconfigured. This allows users to adapt the bag's configuration for different occasions while maintaining simple operation through intuitive coupling mechanisms.
3Adaptability or versatility
If multiple different bags are manufactured to satisfy different style preferences, then personal expression is supported, but resource consumption and waste increase
Solution Approach 1:
The bag components are designed with universal functionality, where the same first bag body, second bag body, and coupling portion can be configured in multiple ways to create different bag styles. This multi-functionality allows a single set of components to replace what would traditionally require multiple different bags, reducing material consumption and waste while still supporting personal expression and style customization.

AI summary
A changeable bag includes a first bag body having a first accommodating portion; a second bag body having a second accommodating portion accommodating the first bag body; and a coupling portion that detachably couples the first bag body accommodated in the second bag body to the second bag body, wherein the coupling portion includes a bottom coupling portion that detachably couples a bottom of the first bag body and a bottom of the second bag body.
