Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional labels provide limited information and incur additional costs for anti-counterfeiting and traceability, while QR codes require separate decoding and additional labels, lacking immediate verification and incurring manufacturing costs.
Innovation Solution
A composite information label using silicon ink with thermochromic and ultraviolet fluorescent inks, allowing for miniaturization, high resolution, and environmental adaptability, including a release layer for long-term adherence and combining inks to provide multiple information layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional labels are used to provide product information, then the label area must be large to accommodate all information, but this increases the label size and costs
Solution Approach 1:
The patent merges multiple information layers into a single composite label by combining visible ink for basic information with thermochromic and fluorescent inks for additional information layers, eliminating the need for separate labels or large label areas
Solution Approach 2:
The patent adds dimensional information storage by using thermochromic ink that responds to temperature changes and fluorescent ink that responds to UV light, creating multiple information dimensions within the same physical label space
2Loss of information
If QR codes are used to store more information, then information density increases, but additional decoding equipment and separate anti-counterfeiting labels are required
Solution Approach 1:
The composite label provides self-verification capabilities through environmental response - the thermochromic and fluorescent inks automatically reveal additional information when exposed to specific conditions, eliminating the need for external decoding equipment
Solution Approach 2:
The single composite label performs multiple functions: it provides basic visible information, stores hidden thermochromic information, contains fluorescent anti-counterfeiting data, and enables traceability, replacing multiple separate systems
3Reliability
If URL or laser anti-counterfeiting labels are added to QR codes, then anti-counterfeiting function is improved, but manufacturing costs increase
Solution Approach 1:
The patent combines anti-counterfeiting functionality directly into the base label through fluorescent and thermochromic inks, eliminating the need for separate laser labels or URL verification systems
Solution Approach 2:
The label uses composite ink materials with different environmental responses (thermochromic, fluorescent, visible) to create multiple verification layers within a single label structure
4Ease of manufacture
If water-based ink is used for printing, then printing process is simple, but the label lacks friction resistance and water resistance
Solution Approach 1:
The patent uses silicon-based ink materials that provide inherent friction resistance, water resistance, and durability while maintaining printability, replacing conventional water-based inks

AI summary
The present invention provides a composite information label, which includes a basic information module and a variation information module. The basic information module forms a first information, in which the basic information module is a visible ink. The variation information module forms at least one of a second information and a third information, in which the variation information module is a parameter variation ink. The basic information module and the variation information module combined into one or multiple layers, so the basic information module interacted with the variation information module, and the first information, the second information and the third information provides as least one of the functions of the showing, hiding, penetrating or blocking. The present invention also provides the composite information label printing method.
