Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional RFID communication methods are used for data exchange, then communication functionality is achieved, but the chip cannot process complex signals or perform specific processes beyond conventional authentication
Solution Approach 1:
The patent segments the signal processing capability by introducing separate photosensors that detect specific optical excitation profiles from filter material, distinct from conventional RFID communication. This segmentation allows the CPU to handle both conventional communication and complex signal processing independently, resolving the contradiction between enhanced adaptability and device complexity
Solution Approach 2:
The patent introduces filter material as an intermediary between the external excitation source and the photosensor. This intermediary converts specific optical excitation profiles into detectable signals, enabling the chip to process complex signals without directly increasing internal processing complexity, thus resolving the technical contradiction
2Adaptability or versatility
If on-chip sensors trigger exceptions or warm resets, then sensor functionality is achieved, but operational capabilities are restricted
Solution Approach 1:
The patent replaces the conventional exception/warm reset trigger mechanism with a photosensor-based optical detection system. Instead of relying on mechanical or electrical triggers that limit operational capabilities, the photosensor detects optical excitation profiles, enabling diverse operational modes including authentication, process activation, and verification without compromising operational simplicity
Solution Approach 2:
The patent makes the photosensor and filter material combination universal by designing it to work with multiple excitation profiles corresponding to different processes. This multi-functionality allows a single sensor system to handle various operational capabilities including authentication, process activation, and hardware verification, resolving the contradiction between adaptability and ease of operation
3Ease of manufacture
If the chip is integrated in different card materials, then manufacturing flexibility is achieved, but consistent sensor excitation and signal processing become difficult
Solution Approach 1:
The patent changes the parameter of excitation detection by using photosensors that detect optical excitation profiles rather than relying on material-dependent physical or chemical changes. This parameter change allows consistent sensor excitation and signal processing across different card materials, resolving the contradiction between manufacturing flexibility and manufacturing precision
