Chamber Fabric With Free Sections for Easy Chamber Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing chambered fabrics face difficulties in easily opening or shaping the chambers formed between fabric layers, which are often produced with closely lying layers, making it time-consuming and challenging to insert or fill substrates.
Innovation Solution
A chambered fabric design featuring spaced-apart fabric layers connected by floating spacer elements, with unbound regions allowing for free fabric sections that facilitate easy opening and shaping of chambers, enabling production in a single weaving process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If fabric layers are produced close together in a single weaving process, then manufacturing efficiency is improved, but chamber opening becomes difficult and time-consuming
Solution Approach 1:
The fabric structure is segmented into distinct regions: a fabric body region where layers are connected by spacers to form chambers, and free fabric sections where layers are separated and unbound. This segmentation allows the fabric to maintain structural integrity in the body while providing easy access for chamber opening through the free sections.
Solution Approach 2:
The free fabric sections are built into the structure during the single weaving process, preliminarily preparing the fabric for easy chamber opening. The unbound, separated layers in these sections are pre-configured to facilitate subsequent chamber access without requiring additional processing steps.
2Stability of the object's composition
If fabric layers are connected closely by spacers, then structural integrity is improved, but chamber accessibility deteriorates
Solution Approach 1:
Different regions of the fabric have different connection qualities: the fabric body has strong spacer connections for structural integrity, while the free fabric sections have no spacer connections for easy chamber access. This local differentiation of connection strength allows both requirements to be satisfied in different locations.
Solution Approach 2:
The fabric is divided into functional zones with distinct connection characteristics. The segmented structure allows the body portion to maintain stability through spacer connections while the free sections provide accessibility by lacking these connections, enabling easy chamber opening when needed.

AI summary
Chamber fabric (1) comprising two spaced-apart tissue layers (2, 3), each tissue layer (2, 3) comprising warp elements (4) and weft elements (5) bound in a predetermined manner, the tissue layers (2, 3) being connected to each other in the region of a tissue body (6) by floating spacer elements (7), the spacer elements (7) alternately shifting from one tissue layer (2) to the other tissue layer (3) and being unbound in the region between the tissue layers (2, 3), so that a sectionally bounded chamber (9) is formed between the tissue layers (2, 3) and the spacer elements (7) along a first extension (8) of the tissue body (6). A tissue layer (2, 3) is continued as a free tissue section (11) on one side (10, 11) of the tissue body (6) in the direction of the first extension (8) of the tissue body (6). The composite tissue comprises at least two such chamber tissues.The method for using such a chamber tissue (1) is characterized by opening the chamber (9) by means of the free tissue section (12).
