Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing elastic labeling bands face challenges in securely attaching to irregularly shaped articles and maintaining labeling functionality without distortion, while also withstanding transport and handling, especially when including both human and machine-readable indicia.

Innovation Solution

A labeling band assembly featuring a web with a central release agent and lateral edge portions, where an elastic film is bonded to the edge portions to form connection zones, allowing for the creation of perforated labeling bands with a securing mechanism that stretches to accommodate various article sizes and shapes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If elastic material is used to affix labels to irregularly shaped articles, then the labeling band can accommodate various shapes and sizes, but the label may become distorted during stretching and securing

Engineering Contradiction:

Improveaccommodation of irregular shapesVSAvoidlabel distortion

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The labeling band is divided into distinct functional zones: a central label zone with release agent that remains relatively stationary, and lateral elastic zones that provide stretching capability. This segmentation allows the label portion to maintain its shape while the elastic portions accommodate irregular article geometries.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the labeling band have different properties: the central portion has release agent for label detachment and minimal stretch, while the lateral edge portions have elastic properties for stretching and securing. This local differentiation enables the label to remain undistorted while the elastic zones adapt to various shapes.

Inventive Principle:

Principle #3Local quality

2Strength

If the elastic material is made stronger to withstand transport and handling, then the labeling function is maintained, but the ease of application and removal becomes difficult

Engineering Contradiction:

Improvewithstand transport and handlingVSAvoidapplication and removal

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

A release agent is introduced as an intermediary substance between the elastic material and the label. This release agent allows the label to be easily detached from the elastic band during application and removal, while the elastic material itself maintains sufficient strength to withstand transport and handling forces.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If the release agent is applied over the entire web, then the label can be easily removed, but the elastic film cannot be properly bonded to the web at the connection zones

Engineering Contradiction:

Improvelabel removalVSAvoidbonding strength

Core Design Contradiction:

Ease of operationVSStrength

Solution Approach 1:

The release agent is applied selectively only to the central portion of the web where the label is located, while the lateral edge portions remain free of release agent to provide bonding zones. This localized application ensures both easy label removal from the central area and strong bonding at the elastic connection zones.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The web is divided into functional zones with different surface treatments: the central portion has release agent for easy label detachment, while the lateral edge portions have no release agent to ensure strong bonding between the elastic film and web at the connection zones.

Inventive Principle:

Principle #1Segmentation

AI summary

A method of forming an elastic labeling band. The method includes covering a central portion of a web of tag material with a release agent, advancing the web of tag material longitudinally and disposing a layer of molten elastomer over the advancing web of tag material, including over the release agent on the central portion thereof. The layer of molten elastomer is disposed over the web of tag material so that the elastomer bonds only to those portions of the web not covered with the release agent. The method includes curing the elastomer to define, with the web bonded thereto, an advancing web assembly, and separating a longitudinal segment from the web assembly to define an elastic labeling band.
