Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical connectors are used for power and data transfer between the machine and cassettes, then reliable power supply and communication are achieved, but the risk of tampering and unauthorized access increases
Solution Approach 1:
The patent replaces mechanical connectors with inductive coupling coils that transfer power and data wirelessly through magnetic fields. The first coil in the machine and second coil in the cassette enable inductive power transfer and communication without physical contact, eliminating the security vulnerabilities of exposed connectors while maintaining reliable operation.
Solution Approach 2:
The patent introduces magnetic fields as an intermediary medium between the machine and cassette for power and data transfer. The coils generate and transmit electromagnetic energy through the magnetic field, acting as a mediator that enables communication and power supply without direct physical connection, thereby preventing tampering.
2Object-affected harmful factors
If inductive coupling coils are used for wireless power and data transfer, then security against tampering is improved, but the complexity of the system increases
Solution Approach 1:
The patent makes the coils multi-functional by using them for both power transfer and data communication through the same inductive coupling mechanism. This universal approach consolidates what could be separate systems into a single integrated solution, reducing overall system complexity while maintaining security benefits.
Solution Approach 2:
The patent merges power transfer and data communication functions into a single inductive coupling system. By combining these functions that could operate separately into one integrated coil-based system, the patent reduces the number of components and simplifies the overall architecture while achieving the security goals.
3Object-affected harmful factors
If encryption methods are implemented for secure communication, then unauthorized access is prevented, but the processing time and operational speed may be reduced
Solution Approach 1:
The patent applies encryption selectively to only the portions of communication that require security, rather than encrypting all data transmissions uniformly. This partial application of encryption minimizes the impact on communication speed while still protecting sensitive information from unauthorized access.
