Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing looms are limited to single-level twisting healds and jacquard healds, unable to combine different levels of twisting and jacquard healds to produce fabric weaves with varied leno weaves, resulting in singular fabric configurations and breathability limitations.
Innovation Solution
A multi-nested twisting loom with multiple levels of twisting healds, including a second-level and first-level healds, arranged in a staggered manner, combined with a jacquard heald, to form leno and jacquard weaves with varying breathable hole sizes and complex patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If single-level twisting healds and jacquard healds are used, then the loom structure is simple, but the fabric weave configuration is singular and breathability is limited
Solution Approach 1:
The patent implements multi-level nesting of twisting healds, where first-level twisting healds are nested within second-level twisting healds, which are in turn nested within jacquard healds. This nested structure allows multiple levels of twisting operations to be performed simultaneously on different warp groups, creating diverse leno weave patterns with varying breathability characteristics without requiring multiple separate loom units.
Solution Approach 2:
The patent segments the warp yarns into multiple groups, with each group assigned to specific twisting heald levels. First-level twisting healds manipulate certain warp groups while second-level twisting healds manipulate other warp groups, allowing independent control of twisting patterns in different fabric regions. This segmentation enables the creation of complex multi-pattern fabrics with varied breathability zones.
2Adaptability or versatility
If multi-level twisting healds are combined, then fabric breathability and pattern complexity improve, but the loom structure becomes more complex
Solution Approach 1:
The patent extends the traditional single-level heald arrangement into multiple hierarchical levels, adding a vertical dimension to the heald structure. First-level twisting healds operate at one level while second-level twisting healds operate at another level, with each level controlling different warp groups. This multi-dimensional arrangement enables independent control of twisting patterns at different depths, creating fabrics with varied breathability and complex patterns.
3Adaptability or versatility
If uniform leno weave patterns are used, then the weaving process is simple, but the fabric lacks varied breathable hole sizes
Solution Approach 1:
The patent applies different twisting patterns and breathable hole sizes to different local regions of the fabric by assigning specific warp groups to different twisting heald levels. Certain warp groups pass through first-level twisting healds to create leno weaves with specific hole sizes, while other warp groups pass through second-level twisting healds to create leno weaves with different hole sizes. This local differentiation enables the fabric to have varied breathability characteristics in different zones.

AI summary
Disclosed is a multi-nested twisting loom, a method, a fabric weave, and an upper. The multi-nested twisting loom includes several nested twisting heald sets. The nested twisting heald sets are sequentially arranged along a weft direction on the loom. Each nested twisting heald set includes a second-level twisting heald at a front end of a warp advancing direction and a first-level twisting heald at a rear end. The second-level twisting heald is composed of a single twisting heald. The first-level twisting heald is composed of m twisting healds, where m is greater than 1. The leno weave in the present disclosure is composed of different levels of twisted areas, which increases the variety of leno weaves. Breathable holes with different sizes are formed between different levels of twisted areas, which better fit various parts of the human body and meet the different breathable needs of different
