Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If dendritic structures are fabricated using electrodeposition methods, then unique identification tags can be created, but large-scale fabrication and secure application methods were previously lacking
Solution Approach 1:
The patent applies preliminary action by forming the dendritic structure within an encapsulating coating during the fabrication process itself, before the tag is applied to the article. This ensures the structure is protected from tampering from the outset, eliminating the need for separate security measures and enabling both large-scale production and inherent security.
Solution Approach 2:
The encapsulating coating acts as an intermediary that protects the dendritic structure during fabrication and application. The coating is applied over the dendritic structure formed on the substrate, creating a secure, tamper-proof tag that can be mass-produced while maintaining security integrity.
2Reliability
If protective layers are applied to enclose dendritic structures, then tamper-proof security is achieved, but fabrication complexity increases
Solution Approach 1:
The patent merges the dendritic structure formation and protective coating application into a single integrated fabrication process. The encapsulating coating is applied over the dendritic structure in one continuous operation, combining what would traditionally be separate steps into a unified process that reduces overall complexity.
Solution Approach 2:
The encapsulating coating serves multiple functions simultaneously: it protects the dendritic structure from tampering, provides a substrate for application to articles, and enables the tag to be formed in a single fabrication process. This multi-functionality reduces the need for additional components or steps.
3Adaptability or versatility
If mobile device-based image analysis is used for identification, then authentication capability is enhanced, but image analysis accuracy and reproducibility challenges remain
Solution Approach 1:
The patent creates a physical copy or replica of the dendritic structure that can be imaged and analyzed. The encapsulating coating preserves the dendritic structure's unique pattern, allowing accurate optical copying and digital analysis. This enables mobile devices to capture and analyze the unique pattern without direct physical contact, enhancing authentication while maintaining precision.
