Tamper-Evident Price Reduction Label with Segmented Adhesive and Release Zones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional price reduction labels with tamper-resistant slits can be reused when applied on top of existing labels due to the entire surface being coated with release material, leading to removal without tearing.
Innovation Solution
A price reduction label design featuring alternating adhesive and release regions on both surfaces, with strategically placed re-application preventing slits, allowing the label to be wound without backing paper and ensuring it tears when removed, preventing reuse by applying new labels over existing ones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the entire upper surface of the price reduction label is coated with release material to enable use without backing paper, then the ease of operation is improved, but the reliability of preventing reuse deteriorates because the label can be removed without tearing when applied on top of another label
Solution Approach 1:
The label surface is segmented into multiple adhesive regions and multiple release regions in an alternating pattern. This segmentation allows the label to be applied without backing paper while ensuring that when applied over another label, the adhesive regions contact the non-release regions of the underlying label, guaranteeing tearing and preventing reuse.
Solution Approach 2:
Different regions of the label surface are given different properties: adhesive regions have adhesive material for bonding, while release regions have release material for temporary holding during application. This local differentiation ensures that when the label is applied over another label, the adhesive regions contact non-release regions, guaranteeing the label will tear upon removal and preventing reuse.
2Reliability
If the label is designed with alternating adhesive and release regions to prevent reuse when applied on top of other labels, then the reliability of preventing reuse is improved, but the device complexity increases due to the patterned coating requirements
Solution Approach 1:
The label surface is divided into alternating adhesive and release regions, creating a segmented pattern that ensures proper functionality. This segmentation is achieved through coordinated coating of adhesive material on the back surface and release material on the front surface in corresponding alternating patterns, providing a reliable solution for preventing reuse while maintaining manufacturability.
