Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an IC chip is designed to correspond to only one communication standard, then the communication reliability is ensured, but the adaptability to different communication standards deteriorates
Solution Approach 1:
The IC chip is designed to support multiple communication standards (RFID, NFC, magnetic secure transmission) within a single device, enabling the magnetic tape cartridge to communicate with various types of reading devices regardless of their specific communication standard, thus achieving universal compatibility while maintaining reliable communication
2Adaptability or versatility
If multiple IC chips corresponding to different communication standards are mounted, then the adaptability to communication standards is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
Multiple communication standard functionalities are merged into a single IC chip, consolidating what would otherwise require separate chips for RFID, NFC, and magnetic secure transmission standards. This integration reduces the number of components, simplifies the device structure, and lowers manufacturing costs while maintaining support for multiple communication standards
3Adaptability or versatility
If multiple IC chips corresponding to different communication standards are mounted, then the adaptability to communication standards is improved, but the manufacturing cost increases
Solution Approach 1:
The patent combines multiple communication standard capabilities into a single IC chip, reducing the bill of materials by eliminating the need for multiple separate chips. This consolidation simplifies the assembly process, reduces component procurement costs, and lowers overall manufacturing expenses while achieving multi-standard adaptability
