Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If backhaul systems or local specialist installation tools are used for device joining, then security is maintained, but device complexity and operational complexity increase
Solution Approach 1:
The joining device performs self-registration by automatically transmitting its installation code through optical means to the HAN coordinator, eliminating the need for manual intervention, specialized tools, or complex backhaul systems. The device autonomously completes the joining process while maintaining security through encoded information transmission.
Solution Approach 2:
The patent replaces complex mechanical or manual joining mechanisms (such as physical tools, manual code entry, or backhaul system interventions) with an optical communication-based automatic transmission system. This substitution simplifies the joining process while preserving security through encoded information transfer.
2Reliability
If manual code entry or backhaul systems are used, then security protocols are maintained, but ease of operation deteriorates
Solution Approach 1:
The joining device automatically transmits its installation code through optical means to the HAN coordinator without requiring manual intervention. The device performs self-registration autonomously, making the joining process simple and intuitive for end users while maintaining security through encoded information transmission.
3Ease of operation
If optical communication is used for direct transmission, then ease of operation improves, but transmission reliability may be compromised
Solution Approach 1:
The installation code is pre-encoded with cryptographic protection before transmission. This preliminary encoding action ensures that even though the transmission occurs over a direct optical link, the information remains secure and accurate, preventing tampering or misinterpretation during the transmission process.
