Fabric Bag With Integrated Weaving And Segmented Folding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fabric bags occupy large storage space due to their bulky folded size and require lengthy sewing times for handle straps, while also forming unattractive creases when unfolded.
Innovation Solution
The fabric bag is designed with inner and outer vertical bent grooves on the body fabric, allowing it to be folded in multiple layers, reducing size, and handle straps are integrally woven and sewn on opposite sides, reducing sewing time and preventing creases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the bag body is folded roughly for storage, then the storage process is simple, but the folded volume is large and occupies excessive storage space
Solution Approach 1:
The bag body is divided into multiple folding sections with bent grooves at regular intervals, allowing the fabric to be folded into compact layers rather than a single large fold, thereby reducing the folded volume while maintaining simple storage process
Solution Approach 2:
The bag is folded not only in the horizontal direction but also in the vertical direction through multiple layers created by bent grooves, utilizing three-dimensional folding to maximize space reduction in a compact storage form
2Ease of manufacture
If the bag body is folded roughly for storage, then the storage process is simple, but unattractive random creases are generated when unfolded
Solution Approach 1:
The bag body is segmented into regular folding sections with predetermined bent grooves, ensuring that folds occur only at designated locations rather than random positions, which prevents unattractive irregular creases while maintaining simple storage process
Solution Approach 2:
The bent grooves are pre-formed in the fabric during manufacturing, preparing the bag in advance for neat folding. This preliminary structuring ensures that when the bag is folded for storage, it follows predetermined paths that prevent random crease formation
3Adaptability or versatility
If handle straps are produced independently and fastened through sewing twice, then the handle straps can be separately manufactured, but the sewing time is long and productivity is degraded
Solution Approach 1:
The handle straps are merged with the bag body fabric in a single integrated weaving process, creating a unified structure where the handle straps are formed as extensions of the main fabric. This eliminates the need for separate manufacturing and multiple sewing operations, significantly reducing sewing time while maintaining manufacturing flexibility

AI summary
A fabric bag and a method for producing the fabric bag are proposed. The fabric bag may be maximally reduced a folded volume of a bag body when folded and stored, by enabling the bag body to be folded in multiple layers to reduce its size in left and right directions, and includes: a body fabric including a front body fabric, a lower folded part, and a rear body fabric; a bag body produced by folding the lower folded part of the body fabric and sewing ends of opposite sides of the folded body fabric with side sewing parts; and a handle strap woven to extend integrally on each opposite side of an open end of the rear body fabric and having each end thereof to be woven and connected to each opposite side of the open end of the front body fabric by a strap sewing part.
