Textile Fabric Sealing Edge with Low Weave Density
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production of auxiliary channels in textile fabrics for sealing fillable chambers is complex and negatively affects the appearance of the fabric, making it difficult to achieve both effective sealing and aesthetic requirements.
Innovation Solution
A method involving a textile fabric with a One Piece Woven (OPW) structure, where a flat sealing edge with a lower weave density is designed to allow a sealant to penetrate and solidify, creating a reliable seal without the need for an additional filling channel, and the jacquard weaving process is used to produce this design with varying densities for precise sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an auxiliary channel is formed to fill sealing compound for sealing contact areas, then sealing reliability is improved, but device complexity and manufacturing complexity increase
Solution Approach 1:
The invention extracts the sealing function from a separate auxiliary channel structure and integrates it directly into the fabric weave pattern itself. The sealing elements are taken out as a distinct structural component and embedded within the fabric's own architecture, eliminating the need for separate sealing channels while maintaining sealing reliability.
Solution Approach 2:
The invention merges the sealing function with the fabric structure by integrating sealing elements directly into the weave pattern. Instead of having separate sealing channels and fabric layers, the sealing capability is combined with the fabric's own structural elements, simplifying the overall device complexity while maintaining sealing effectiveness.
2Reliability
If an auxiliary channel is formed for sealing, then sealing effectiveness is improved, but appearance quality deteriorates
Solution Approach 1:
The sealing function is merged with the fabric's own structural elements, making the sealing components invisible or indistinguishable from the rest of the fabric surface. This integration eliminates the visual impact of separate auxiliary channels while maintaining sealing effectiveness.
Solution Approach 2:
The fabric structure is designed with localized variations in weave density or material properties at specific contact areas, creating sealing zones that are visually integrated with the surrounding fabric. These local modifications provide sealing functionality without disrupting the overall surface appearance.
3Reliability
If fabric layers are attached and bonded together, then tightness of fabric pockets is improved, but sealing of contact areas becomes difficult
Solution Approach 1:
The sealing elements are pre-integrated into the fabric structure during the weaving process, before the fabric layers need to be attached and bonded. This preliminary integration of sealing capability eliminates the need for subsequent sealing operations, making the manufacturing process easier while maintaining fabric tightness.
Solution Approach 2:
The fabric structure is designed to be self-sealing through its own integrated sealing elements, eliminating the need for external sealing compounds or additional bonding steps. The fabric layers attach and bond together while the embedded sealing elements automatically provide the necessary sealing at contact areas.
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 method allows for simple and effective sealing of fillable chambers while maintaining a high aesthetic quality, as the sealant is limited to the sealing edge and the fabric can withstand high pressures and external loads, with the added benefit of eliminating the need for an additional sealing compound.
Implementation Method 1
a lower weave density than adjacent textile areas and subsequently coated with the sealing compound... such that a suitable sealant, such as silicone, can penetrate the fabric of the sealing edge, for example, through pressure, diffusion, or capillary action
Implementation Method 2
the jacquard weaving process is used to produce this design with varying densities for precise sealing
