Folded Fabric Bonding Structure to Prevent Filling Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fabric bonding methods, such as sewing and adhesive use, fail to provide durable connections while preventing filling discharge, especially when ventilation holes or sewing lines are formed, leading to issues with product quality and durability.
Innovation Solution
A fabric bonding structure using a bonding member with a strap form, folded to create internal regions, where fillings are isolated from the outside, and a sealing line is formed without sewing, using an adhesive to bond the member to the fabrics, ensuring even distribution of deformation forces and preventing filling discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If sewing is used to connect fabrics, then bonding strength is improved, but filling discharge occurs through needle holes
Solution Approach 1:
A bonding member is introduced as an intermediary component between the first and second fabrics. This bonding member includes a first surface that bonds to the first fabric and a second surface that bonds to the second fabric, eliminating the need for direct sewing between fabrics and preventing filling discharge through needle holes while maintaining bonding strength.
2Object-generated harmful factors
If adhesive bonding is used to prevent filling discharge, then filling discharge is prevented, but bonding force deteriorates over time
Solution Approach 1:
The bonding member is constructed as a composite structure with a first surface optimized for bonding to the first fabric and a second surface optimized for bonding to the second fabric. This composite design allows the use of different bonding mechanisms or materials on each surface, achieving both filling discharge prevention and long-term bonding force durability.
3Object-generated harmful factors
If adhesive bonding is used to connect fabrics, then filling discharge is prevented, but bonding structure deforms under external force
Solution Approach 1:
The bonding structure is segmented into distinct components: the first fabric, the bonding member, and the second fabric. The bonding member acts as a separate structural element that can be designed with specific mechanical properties to resist deformation under external force while maintaining its bonding function, thus preventing both filling discharge and structural deformation.
4Adaptability or versatility
If sewing lines are formed for finishing clothes, then design and function are improved, but filling discharge occurs through sewing lines
Solution Approach 1:
The bonding member serves as an intermediary that enables the formation of sewing lines or ventilation holes for design and functional purposes while preventing filling discharge. By providing a dedicated bonding interface, the bonding member allows sewing operations to be performed on the bonding member itself rather than directly on the fabric layers, thus maintaining both design flexibility and filling containment.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution provides excellent bonding force without forming sewing lines, prevents filling discharge, and maintains durability even with external forces or design elements like ventilation holes, enhancing the quality and longevity of fabric goods.
Implementation Method 1
The bonding member may be bonded to the first fabric and the second fabric by using an adhesive.

AI summary
Disclosed are a fabric bonding structure and processed fabric goods having the same. The fabric bonding structure includes: a first fabric; a second fabric provided so as to be in contact with the first fabric; and a bonding member having a first surface and a second surface at the other side of a side of the first surface, and being folded so that two points of the first surface meet, and the second surface being bonded to each of the first fabric and the second fabric, and the fabric bonding structure is applicable to processed fabric goods, such as clothes and bedclothes. According to the fabric bonding structure and the processed fabric goods having the same, it is possible to isolate fillings filled inside a fabric from the outside even without forming a sewing line, and bonding force at a bonding portion is excellent compared to a method of forming a sewing line or a bonding method using an adhesive in the related art.
