Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional anti-counterfeiting labels with encrypted codes, QR codes, RFID tags, and hologram stickers are used, then product identification and tracking capabilities are improved, but vulnerability to replication and counterfeiting increases due to high-quality digital scanning and printing machines
Solution Approach 1:
The patent applies photo-chromic nano particles that change color when exposed to UV light, creating dynamic visual effects that are extremely difficult to replicate. This color-changing property provides a reliable authentication mechanism that resists counterfeiting, as static color patterns can be easily copied by digital printing machines.
Solution Approach 2:
The label combines multiple materials with different properties: cellulose base layer for structural integrity, photo-chromic nano particles for dynamic color change, silica-infused macro particles for three-dimensional texture, and fade-resistant transparent plastic sheet for protection. This composite structure creates authentication features that are difficult to replicate with conventional printing technologies.
2Reliability
If high secure anti-counterfeiting labels with multiple security features are implemented, then protection against tampering and illegal handling is improved, but ease of manufacture decreases due to complex production processes
Solution Approach 1:
The patent merges multiple authentication features into a single integrated label structure: the photo-chromic nano particles, silica-infused macro particles, and QR code are all applied to one label during the manufacturing process. This consolidation maintains high security protection while simplifying production compared to applying multiple separate security features.
Solution Approach 2:
The patent uses photo-chromic nano particles that change their optical parameters (color) in response to UV light exposure. This dynamic parameter change provides enhanced security without requiring complex mechanical structures or multi-step manufacturing processes, as the effect is achieved through material property changes during a single production cycle.
3Reliability
If three-dimensional structures with multi-colored particles and photo-chromic nano particles are applied to foundation paper, then anti-counterfeiting capabilities are improved, but manufacturing precision requirements increase due to the need for dense coating and laminating
Solution Approach 1:
The patent employs a dense coating of particles on the foundation paper that creates a porous yet uniform structure. The photo-chromic nano particles and silica-infused macro particles are distributed throughout this coating, providing unique authentication patterns while maintaining manufacturing feasibility through controlled porosity that allows for uniform particle distribution without requiring extreme precision.
4Productivity
If QR code authentication with GPS coordinates is implemented, then instant authentication capability is improved, but device complexity increases due to the integration of multiple authentication mechanisms
Solution Approach 1:
The QR code on the label serves multiple functions: it provides instant authentication when scanned, stores GPS coordinates for location tracking, and can trigger counterfeit alerts. This multi-functionality achieves rapid authentication and enhanced security without requiring separate devices or systems, as all capabilities are integrated into a single QR code structure that can be read by standard scanning devices.

AI summary
“Non-fungible anti-counterfeit photo-chromic nano-micro three-dimensional tags/labels are designed in such a manner that duplication and counterfeiting of the labels are prevented. The label comprises of a frame quick response (QR) code part (103), which surrounds a three-dimensional sticker part, which consists of a foundation paper (113) made of cellulose, a non-fungible three-dimensional (3D) structure and a fade-resistant transparent plastic sheet (201). The structure consists of multi-colored micro particles (107), silica-infused 3D macro particles (109) and the photo-chromic nano particles (111). The sheet is laminated on the paper after application of dense coating of particles. The code part contains all information about the sticker part and is scannable by a specific application module, which allows to scan the code part to recognize the data in the code part, to direct the data to a customer's database server, which instantly maps the code data with the scanned image that is stored in its database to verify label authenticity. If the data matches with each other, the backend server sends a message to the application module that the product is genuine. In case of any variation between the scanned and stored data, the system sends a counterfeit alert to the application user, instantly requests to take the GPS coordinates of the location and sends report to manufacturer's designated contact.
