Solution Overview

Problem

The existing process for producing woven articles with superimposed ribbons requires separate weaving and stitching steps, leading to increased production costs and time due to the need for different equipment and operators.

Innovation Solution

A weaving process and loom configuration that allows for the simultaneous weaving and stitching of superimposed ribbons, using a horizontal loom with separate heddles and shuttle elements to interlace and stitch the ribbons in a single operation, reducing the complexity and cost of production.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate weaving and stitching steps are used to produce superimposed ribbons, then the ribbons can be produced with different decorations and materials, but the production time and costs increase due to multiple processing steps and equipment

Engineering Contradiction:

Improveribbon decoration and material varietyVSAvoidproduction time and cost

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent combines the weaving and stitching operations into a single integrated process. The loom is configured with multiple heddles and shuttles that can simultaneously weave multiple ribbons and stitch them together in one continuous operation, eliminating the need for separate weaving and stitching steps while maintaining the ability to use different materials and decorations for each ribbon.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The loom is designed as a multi-functional device that can perform both weaving and stitching operations. The stitching mechanism is integrated into the loom structure, allowing the same machine to create both the woven ribbons and the stitching that joins them, rather than requiring dedicated separate equipment for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of manufacture

If separate weaving and stitching steps are used, then different equipment can be optimized for each function, but the number of operators and equipment complexity increase

Engineering Contradiction:

Improveequipment optimization for each functionVSAvoidnumber of equipment and operators

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent merges multiple functions into a single loom system. The stitching mechanism is integrated directly into the loom structure, with stitching threads and heddles built into the weaving machine itself, eliminating the need for separate stitching equipment and reducing overall system complexity despite the multi-functional capability.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The loom is designed as a universal machine that performs both weaving and stitching functions. The same equipment handles multiple tasks through coordinated operation of different components (multiple heddles, shuttles, and stitching mechanisms) rather than requiring specialized separate machines for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If multiple separate processing steps are used, then each step can be controlled independently, but the production process becomes more complex and requires more operators

Engineering Contradiction:

Improveindependent process controlVSAvoidprocess complexity and operator requirements

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent combines multiple process controls into a single integrated system. The loom's control mechanism coordinates the weaving and stitching operations simultaneously through a unified control structure, reducing the need for multiple independent control systems while maintaining the ability to control different aspects of the process.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A process for weaving superimposed ribbons which are stitched to each other comprises a sequence of successive cycles, in which each cycle comprises the steps of: - providing on a loom (10) a first plurality of warp threads (21) which are intended for weaving a lower ribbon (1), subdividing them between a first upper row (24) of threads and a first lower row (25) of threads so as to define between the first rows of threads a first shed (26), - providing on the loom a second plurality of warp threads (31) which are intended for weaving an upper ribbon (2), subdividing them between a second upper row (34) of threads and a second lower row (35) of threads so as to define between the second rows of threads a second shed (36), wherein the second lower row (35) of threads is positioned higher than the first upper row (24) of threads, - passing a first weft thread (23) through the first shed (26) and a second weft thread (33) through the second shed (36), - moving at least one or more of the warp threads (21) of the lower ribbon (1) between the first upper row (24) and the first lower row (25) so as to bind the first weft thread (23), - moving at least one or more of the warp threads (31) of the upper ribbon (2) between the second upper row (34) and the second lower row (35), so as to bind the second weft thread (33), - providing on the loom at least one stitching thread (17) which extends between the pluralities of warp threads (21, 31), wherein the stitching thread is moved, at the time of one or more cycles, between the second upper row (34) and the first lower row (25), and vice versa, so as to bind together the first and second weft thread (23, 33).
