Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a physical connection is used between the reader device and computing device, then data security is improved, but device portability and user convenience deteriorate
Solution Approach 1:
The patent replaces the mechanical physical connection system with a wireless communication system. The reader device communicates with the computing device via wireless signals, eliminating the need for physical cables or connectors while maintaining data transmission capabilities. This substitution resolves the contradiction by removing the portability barrier without compromising security, as the wireless communication incorporates encryption and authentication protocols.
Solution Approach 2:
The patent introduces cryptographic protocols and security layers as intermediaries between the reader device and computing device. These security mechanisms mediate the wireless communication by encrypting data transmissions and authenticating devices, ensuring that the removal of physical connections does not compromise data security. The intermediary security layer enables wireless communication to achieve both portability and security.
2Ease of operation
If the reader device is made portable and wearable, then user convenience is improved, but data security may deteriorate due to wireless communication
Solution Approach 1:
The patent changes the operational parameters of communication from wired to wireless, and implements dynamic security parameters including encryption keys, authentication tokens, and session management. These parameter changes enable the system to adapt to wireless communication requirements while maintaining security standards. The reader device can adjust security parameters based on communication context, ensuring both portability and security are achieved.
3Reliability
If a physical connection is required, then secure data transfer is improved, but device size and carryability worsen
Solution Approach 1:
The patent replaces the mechanical connection system with wireless communication, eliminating the need for physical cables, connectors, and associated housing structures. This substitution significantly reduces the reader device's weight and size, making it portable and wearable, while the implemented cryptographic security measures ensure that data transfer security is maintained or even enhanced compared to physical connections.
