Fastener Tape Weave Patterns for Thread Attribute Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide fasteners made from environmentally-friendly threads lack effective methods for identifying the use of recycled, biodegradable, or plant-derived materials, making it difficult to trace and manage thread information in production and after delivery.
Innovation Solution
A fastener tape woven from weft and warp threads with identification regions that allow visual or tactile identification of environmentally-friendly characteristics, using specific weave patterns and structures to indicate main and sub-attributes such as certificates or suppliers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If spectroscopic analysis is performed on threads to identify material composition, then material identification capability is improved, but detection difficulty and time consumption increase significantly
Solution Approach 1:
The patent creates a visual copy or representation of thread attributes through colored markers embedded in the fastener tape. Instead of performing complex spectroscopic analysis, the tape incorporates color-coded indicators that directly represent material composition, certification status, and other attributes, allowing instant visual identification without laboratory equipment
Solution Approach 2:
The patent replaces the mechanical/chemical analysis system (spectroscopic analysis) with an optical information system (colored markers). The colored markers serve as visual codes that can be read by human eyes or simple imaging systems, substituting complex analytical instrumentation with simple optical detection
2Loss of information
If multiple certification information is provided on fastener tape, then information completeness is improved, but identification difficulty increases due to lack of visual distinction
Solution Approach 1:
The patent applies different local qualities (colors, patterns, positions) to different regions of the fastener tape to encode specific information. Each colored marker or patterned region represents a specific attribute such as material type, certification level, or supplier information, allowing multiple pieces of information to be visually distinguished and easily identified
Solution Approach 2:
The patent uses color-coded markers embedded in the fastener tape to represent different thread attributes and certification levels. Different colors indicate different material compositions, certifications, or suppliers, enabling instant visual differentiation of multiple information types without requiring complex analysis or text reading

AI summary
Fastener tape is woven from a weft thread and warp threads both of which are threads with a main attribute. The fastener tape includes: first and second side-edges extending along an elongation direction of the fastener tape to define a fastener tape width; and a tape main portion interposed between the first and second side-edges. The tape main portion includes an identification region woven by plural warp threads and the weft thread interlaced with one another, the identification region having an identification region width which is a partial width of an entire width of the fastener tape width and is a width in accordance with a number of the plural warp threads. Structure of the identification region is configured to allow identification that the weft thread and the warp threads are with the main attribute and/or to allow identification of a sub-attribute subdivided from the main attribute.
