Flexible Condition Change Labels for High-Speed Vial Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current condition change labels are not suitable for unit application to vials and syringes due to stiffness issues, which prevents them from wrapping these shapes without flagging and requires high-speed application, and existing indicators are too bulky or stiff for high-speed use.
Innovation Solution
Condition change labels with a stiffness range of 0.001 mN·m to 0.06 mN·m, featuring a laminated structure with a blister to house an indicator substance and an adhesive for flexible yet rigid application, allowing them to wrap curved surfaces without flagging and be used in high-speed label applicators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If condition change labels are made rigid to detach from liner, then they can be applied by high speed label applicator, but they cannot wrap curved surfaces without flagging
Solution Approach 1:
The patent applies parameter changes by precisely controlling the stiffness of the label within a specific range (0.001 to 0.06 mN·m). This quantitative parameter optimization allows the label to exhibit both rigidity for high-speed application and flexibility for wrapping curved surfaces, resolving the contradiction between these two opposing requirements.
2Shape
If condition change labels are made flexible to wrap curved surfaces, then they can conform to vials and syringes, but they cannot detach from liner for high speed application
Solution Approach 1:
The patent resolves this contradiction by establishing a specific stiffness parameter range (0.001 to 0.06 mN·m) that enables the label to achieve optimal balance between flexibility for wrapping and rigidity for detachment during high-speed application.
3Volume of stationary object
If existing indicators are made bulky to house indicator substance, then they can contain sufficient indicator material, but they are too stiff for high speed application
Solution Approach 1:
The patent applies this principle by using a thin, flexible label structure that houses the indicator substance in a compact manner. The label's flexibility allows it to conform to curved surfaces and enable high-speed application, while still containing sufficient indicator material through efficient spatial arrangement.
Solution Approach 2:
The patent optimizes the physical parameters of the label, particularly its stiffness (0.001 to 0.06 mN·m) and thickness, to achieve a balance between indicator substance capacity and flexibility for high-speed application.

AI summary
Described herein are condition change labels, methods of forming them, and methods of using them. Generally, condition change labels include a first layer including a blister laminated to a first side of a bottom layer thereby creating a container; an indicator substance located in the container; and an adhesive disposed on at least a portion of a second side of the bottom layer, wherein the condition change label has a stiffness less than about 0.06 mN•m.
