Solution Overview

Problem

Existing flexible self-adhesive labels face issues where the liner detaches from the adhesive layer during use, leading to waste and contamination, and previous solutions involving multiple overlapped labels are costly.

Innovation Solution

A flexible self-adhesive label design with a selectively peelable liner, featuring a base region and anti-tear configurations that prevent the liner from separating from the adhesive layer, ensuring the liner remains attached and reducing waste, while allowing the adhesive region to be exposed for use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the liner is removed from the adhesive layer, then the adhesive region can be exposed for use, but the liner detaches and becomes waste that is often disposed incorrectly

Engineering Contradiction:

Improveselective peeling of adhesive regionVSAvoidliner waste and contamination

Core Design Contradiction:

Ease of operationVSLoss of substance

Solution Approach 1:

The liner is divided into two distinct regions: a first liner region that can be selectively peeled away to expose the adhesive, and a second liner region that remains attached to the label body. This segmentation allows the useful portion of the liner to be removed while the protective portion stays with the label, preventing waste and contamination.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The fold line acts as an intermediary mechanism that connects the removable first liner region to the retained second liner region. This fold line allows controlled separation of the liner portions while maintaining the connection between the liner and label body through the base region, enabling selective exposure without complete detachment.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of manufacture

If a single label with covered adhesive region is used, then manufacturing costs are reduced, but the liner may detach during use

Engineering Contradiction:

Improvesingle label structureVSAvoidliner attachment stability

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The liner is segmented into a removable first region and a retained second region, allowing the label to maintain a simple single-label structure while ensuring the liner remains attached where needed. This segmentation provides reliability without requiring multiple overlapped labels.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The solution moves from considering the liner as a single flat layer to a multi-dimensional structure with folded portions and distinct regions. The fold line creates a three-dimensional configuration that allows part of the liner to be removable while keeping other parts attached, resolving the contradiction between simplicity and reliability.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

Flexible self-adhesive label with a covered adhesive region selectively peelable, the label comprising a flexible layer (10); a pressure-sensitive adhesive layer (20) covering at least a first region (22) of a first side of the flexible layer (10); a liner (30) with a first liner region (32) adhered over the first region (22) and intended to be removed from the first region (22) leaving it exposed; wherein the adhesive layer (20) also covers a second region (23) of the first side of the flexible layer (10); and the liner (30) includes a base region (31), attached to the second region, the base region (31) and the first liner region (32) being connected through a first fold line (33) whose ends are approximately tangent to anti-tear configurations (36) of the liner (30), allowing to expose the first region (22) keeping the liner (30) attached to the second region (23).
