Engineering Contradiction Analysis
1Ease of operation
If electronic access control systems are used, then access authorization can be granted conveniently, but the system becomes vulnerable to hacking and unauthorized access
Solution Approach 1:
The access control system is segmented into multiple independent components: electronic identification (RFID/magnetic strip) and physical identification (microparticle arrangement). Each component provides a separate layer of security, so that compromise of one does not necessarily compromise the entire system. The microparticles are further segmented into multiple layers with different colors and positions, creating a complex physical identifier that is difficult to replicate.
Solution Approach 2:
The system uses composite identification media combining electronic components (RFID chips, magnetic strips) with physical components (microparticles made of melamine-alkyd resin with multiple colored layers). This composite approach creates a multi-modal identification system that is more resistant to hacking than purely electronic systems, while maintaining ease of operation through integrated reading mechanisms.
2Reliability
If multiple layers of microparticles are used to create unique identification, then forgery resistance increases, but manufacturing complexity increases
Solution Approach 1:
The microparticles are manufactured as inexpensive, simple objects using straightforward layer deposition techniques. While each particle has multiple layers for identification purposes, the manufacturing process uses cost-effective materials (melamine-alkyd resin) and simple deposition methods, making the complex appearance achievable through economical means. This allows high forgery resistance without prohibitive manufacturing costs.
Solution Approach 2:
The system creates unique microparticle identifiers by varying multiple parameters: the number of layers, the color of each layer, the thickness of layers, and the spatial arrangement of particles. These parameter variations can be controlled during manufacturing to create billions of unique combinations, providing high forgery resistance while using relatively simple manufacturing processes that only require precise control of these parameters rather than complex assembly operations.
