Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional wireless communication systems are used for ad hoc networks, then information exchange between devices is enabled, but the configuration process becomes complex and requires significant user intervention
Solution Approach 1:
The patent applies preliminary action by pre-configuring access modes with identifiers and cryptographic parameters before actual communication occurs. The system stores access modes with associated identifiers and cryptographic means in advance, so that during information exchange, the user simply selects the appropriate access mode without needing to perform complex configuration procedures. This resolves the contradiction by preparing the complexity beforehand, making operation simple during use.
Solution Approach 2:
The system implements self-service through automatic identification and authentication mechanisms. When a user selects an access mode, the system automatically retrieves the associated identifier and cryptographic parameters, performs authentication without manual intervention, and establishes the communication channel automatically. This eliminates the need for users to manually configure complex network parameters, thereby simplifying operation while maintaining security.
2Extent of automation
If manual configuration methods are used for wireless communication, then user control over data exchange is maintained, but the process requires prolonged user intervention
Solution Approach 1:
The patent stores access modes with their associated identifiers and cryptographic parameters in advance within the device memory. During information exchange, the user simply selects the desired access mode, and the system automatically retrieves and applies the pre-configured parameters, eliminating the need for real-time configuration. This preliminary preparation dramatically reduces configuration time while enabling automatic data exchange.
Solution Approach 2:
The system implements feedback mechanisms where the selected access mode automatically triggers the retrieval and application of corresponding cryptographic parameters and identifiers. The system provides automatic feedback by validating the selected mode, retrieving associated parameters, and establishing the communication channel without requiring additional user input. This feedback loop enables automatic data exchange while minimizing user intervention time.
3Reliability
If cryptographic means are implemented for secure data exchange, then information security is improved, but the complexity of data handling increases
Solution Approach 1:
The patent pre-stores cryptographic parameters including public keys, private keys, and encryption algorithms associated with each access mode before actual communication occurs. When a user selects an access mode, the system automatically retrieves and applies the pre-configured cryptographic means for data encryption and authentication. This eliminates the need for users to manually manage complex cryptographic operations, thereby maintaining high security while reducing the perceived complexity of data handling.
Solution Approach 2:
The system performs self-service by automatically managing cryptographic operations including key retrieval, data encryption, and authentication validation. When an access mode is selected, the system autonomously handles all cryptographic processing without requiring user intervention in the complex data handling procedures. This automation maintains strong security while abstracting away the complexity from the user perspective.
4Ease of operation
If hardware transmission devices are used for wireless communication, then direct device connection is enabled, but the need for physical connections increases complexity
Solution Approach 1:
The patent replaces mechanical connection systems with wireless communication interfaces that use electromagnetic fields for data transmission. Instead of requiring physical hardware connections between devices, the system uses wireless interfaces with associated access modes that enable communication through electromagnetic signals. This substitution eliminates the complexity of physical connections while maintaining the functionality of direct device communication, thereby simplifying operation without sacrificing connection capability.
