Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional RFID label application methods face challenges when applied to articles with materials that interfere with electromagnetic waves, such as metal or water, leading to inefficient operations and potential label detachment, especially when using hollow tubes which require additional adhesive or cellophane tape and can cause articles to lean during stacking.

Innovation Solution

A RFID label application method and device that allows the RFID tag to be partially separable from the article without special members, using a label design with a tag-fixed portion that can be raised from the common label portion along a partition line, reducing interference from the article's material and enabling efficient application by folding and applying mechanisms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If hollow tubes are used to create gap between label and article, then electromagnetic wave interference is reduced, but device complexity and manufacturing difficulty increase due to need for additional adhesive or cellophane tape

Engineering Contradiction:

Improveelectromagnetic wave interferenceVSAvoidlabel structure complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The label is divided into two distinct portions: a common label portion that adheres to the article and a tag-fixed portion that houses the RFID tag. These portions are connected by a hinge structure, allowing the tag-fixed portion to be raised away from the article surface, creating the necessary gap without hollow tubes or additional fastening materials.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The hinge structure enables dynamic positioning of the tag-fixed portion, allowing it to transition between a lowered position (flush with the article) and a raised position (creating gap for electromagnetic wave transmission). This dynamic adjustment optimizes both adhesion and RFID communication based on the application context.

Principle #15Dynamics

2Object-affected harmful factors

If hollow tubes are used to create gap between label and article, then electromagnetic wave interference is reduced, but operational efficiency decreases due to additional steps for adhesive or cellophane tape application

Engineering Contradiction:

Core Design Contradiction:

Object-affected harmful factorsVSProductivity

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The hinge structure inherently provides the gap-making function without requiring external adhesive or cellophane tape. The mechanical design of the hinge itself enables the tag-fixed portion to be raised and positioned, eliminating additional operational steps and improving application efficiency.

Inventive Principle:

Principle #25Self-service

3Object-affected harmful factors

If hollow tubes are used to create gap between label and article, then electromagnetic wave interference is reduced, but stability decreases causing articles to lean during stacking

Engineering Contradiction:

Core Design Contradiction:

Object-affected harmful factorsVSStability of the object's composition

Solution Approach 1:

The hinge structure enables dynamic positioning of the tag-fixed portion, allowing it to transition between a lowered position (flush with the article, maintaining stability during stacking) and a raised position (creating gap for electromagnetic wave transmission during RFID operations). This dynamic adjustment resolves the conflict between stability and electromagnetic wave interference reduction.

AI summary

A RFID tag is partially separable from an article to which the tag is applied such that influence on the RFID tag from the article may be reduced thereby. A label is applied to an article, wherein the label is tacked on a backing paper. The label is fixed with a tag-fixed portion fixed with a RFID tag comprising an IC chip and a communication antenna. The tag-fixed portion has a predetermined size and is partitioned from a common label portion. The common label portion is partitioned into a first label portion that is articulated with the tag-fixed portion and a second label portion, from which the tag-fixed portion is separable along a partition line extending across the common label portion from a side of the tag-fixed portion. The method comprises associating the first label portion of the common label portion with a first surface of the article such that the partition line of the label follows a corner line of a corner portion of the article, and applying the label to the article such that the tag-fixed portion articulated with the first label portion is raised from the article.
