Cold-Weather Gear Batting Retention Using Interlaced Linear Members
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cold-weather protection gear, such as sleeping bags, face issues with batting leaning, leading to reduced heat insulation, increased weight, and decreased loft due to quilting or non-woven cloth usage, which also compromises cushioning and productivity.
Innovation Solution
A cold-weather protection gear with a lining, surface cloth, and batting, held in place by first and second linear members comprising chenille yarns extending in different directions, preventing batting leaning and maintaining loft without additional seams or partitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If quilting is used to prevent batting leaning, then batting stability is improved, but heat insulation deteriorates due to loft collapse
Solution Approach 1:
The invention divides the batting retention function into multiple discrete linear members spaced at intervals, rather than using continuous quilting. This segmentation allows the batting to be held stable without compressing it across the entire surface, preserving loft and heat insulation in the spaces between linear members.
Solution Approach 2:
The linear members provide localized batting retention only at specific points where needed, rather than uniformly constraining the batting across the entire garment. This local approach maintains batting stability where required while preserving overall loft and insulation properties in non-constrained areas.
2Stability of the object's composition
If non-woven cloth is superposed to lock batting, then batting retention is improved, but weight increases and productivity decreases
Solution Approach 1:
The invention extracts the essential function of batting retention from the complex non-woven cloth system and implements it through simple linear members that can be easily attached. This extraction eliminates the need for complex bonding processes while maintaining effective batting retention.
Solution Approach 2:
The invention changes the physical form of the retention mechanism from a continuous non-woven fabric layer to discrete linear members with specific spacing and orientation. This parameter change simplifies the manufacturing process while achieving the same retention function more efficiently.
3Stability of the object's composition
If non-woven cloth is used to hold batting, then batting stability is improved, but cloth softness deteriorates
Solution Approach 1:
The invention copies only the essential retention function of the non-woven cloth using simple linear members, eliminating the need for the bulky non-woven material itself. This allows the garment to maintain batting stability while preserving the natural softness of the primary fabrics.
4Stability of the object's composition
If partitions are sewn to prevent batting leaning, then batting stability is improved, but device complexity increases
Solution Approach 1:
Instead of using complex partition structures that divide the garment into sections, the invention inverts the approach by using simple linear members that run across the garment. This inverted simplicity reduces structural complexity while achieving effective batting stabilization.
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
The solution provides excellent heat insulation, lightweight, and soft texture while allowing compact storage and improved productivity by eliminating the need for quilting and non-woven cloths.
Implementation Method 1
a plurality of first effect strands extending from each of the first core strands to the periphery of the first core strands and interlacing with the batting
Implementation Method 2
Warmness of the cold-weather protection gear having such a structure depends on a thickness of the batting which creates an immovable air layer

AI summary
Cold-weather protection gear is provided which includes a lining that covers a user; a surface cloth that covers the lining; and batting enclosed between the lining and the surface cloth. Linear members located between the lining and the surface cloth extend in a first direction while meandering, and are aligned with each other at an interval in a second direction crossing the first direction. Each of the linear members includes at least one core strand extending in the first direction; and a plurality of effect strands extending from each of the core strands and interlacing with the batting such that the batting is held in place relative to the linear members.
