Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic identification tags for textile parts are bulky, difficult to integrate into seams, and prone to damage during sewing, limiting their practicality for widespread deployment in the clothing industry.
Innovation Solution
A method for securing an electronic tag to a textile part by embedding a wired electronic device comprising a chip and an antenna wire within a stitched seam, specifically using overlock stitches to protect and integrate the tag seamlessly into the textile.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional RFID tags with plastic supports and conductive tracks are used, then the tags have sufficient structural integrity and ease of handling, but the tags become bulky and difficult to integrate into textile seams
Solution Approach 1:
The conventional RFID tag structure is segmented into its essential functional components: the electronic chip and the antenna wire. The non-essential bulk components (plastic support, large conductive tracks) are removed or minimized. This segmentation allows the tag to be reduced to a compact form that can be easily integrated into textile seams while retaining its identification functionality.
Solution Approach 2:
The essential functional elements (chip and antenna wire) are extracted from the bulky conventional tag structure. By removing the large plastic support and extensive conductive tracks, the invention isolates only the necessary components for RFID operation, enabling seamless integration into textile products without the bulk of traditional tags.
2Reliability
If transponders are placed in textile seams using conventional methods, then identification functionality is achieved, but the transponders are prone to damage during sewing and can slip out of the seam
Solution Approach 1:
The RFID tag integration process is merged with the seam formation process itself. The chip and antenna wire are positioned within the seam path, and the sewing operation simultaneously creates both the structural seam and the protective enclosure for the RFID components. This merging eliminates the need for separate attachment steps and ensures the tag is permanently secured within the seam structure.
Solution Approach 2:
The chip and antenna wire are preliminarily positioned within the seam path before the sewing operation commences. This preliminary positioning ensures that as the seam is formed, the RFID components are automatically enclosed and protected by the stitching, preventing damage and slippage without requiring additional securing steps.
3Volume of moving object
If wired electronic devices are integrated into textile seams, then the tags become compact and easily integratable, but the chip and antenna wire require precise positioning to avoid damage during sewing
Solution Approach 1:
An intermediary positioning structure or guide mechanism is introduced to facilitate the precise placement of the chip and antenna wire within the seam path. This intermediary element ensures that the RFID components are correctly positioned before sewing begins, allowing compact integration without requiring extremely high precision during the actual sewing operation, as the positioning is established in a preliminary stage.

AI summary
A method for making a textile part, comprising a step of forming a stitched seam. The stitched seam step also aims to secure an electronic tag to the textile part. The electronic tag is formed from a strip comprising a wired electronic device comprising a chip associated with at least one antenna wire, the chip and the antenna wire being arranged inside the stitched seam. The invention also relates to the textile part provided with the tag.
