Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the link integrity function is employed to stop communication function when a specific communication path has failure, then network reliability is improved, but device complexity increases and manual intervention is required
Solution Approach 1:
The access point stores multiple relay modes with different communication paths in advance. When a communication failure occurs, the system can immediately switch to a pre-configured alternative path without requiring real-time manual intervention or complex dynamic routing calculations.
Solution Approach 2:
The access point autonomously monitors communication path status and automatically switches between relay modes based on detected failures. This self-service capability eliminates the need for manual intervention by network managers while maintaining high network reliability.
2Ease of operation
If the access point autonomously manages communication parameters for multiple communication paths, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The communication parameters are segmented into discrete relay modes, each representing a specific communication path configuration. This segmentation allows the access point to manage complexity by treating each path as an independent, switchable unit rather than managing continuous parameter adjustments.
Solution Approach 2:
The system manages communication parameters by defining distinct relay modes with different parameter sets (communication paths, authentication methods, etc.). Switching between modes involves changing these parameters in a controlled manner, making the complexity manageable through parameter discretization.
3Adaptability or versatility
If multiple relay modes with different communication paths are stored, then adaptability is improved, but memory requirements increase
Solution Approach 1:
The access point is designed with multi-functionality to handle multiple relay modes, allowing a single device to serve multiple communication paths and failure scenarios. This universal design enables the system to adapt to different network conditions without requiring separate dedicated systems for each path.

AI summary
A relay device performing wireless communication with a wireless communication device to relay communication between the wireless communication device and another communication device. First and second relay modes of the relay device each include a set of communication parameters for relaying communication via respective first and second communication paths. The relay device includes a communication failure determination section for determining, whether there is a communication failure in the first communication path, and a relay mode controlling section for enabling the first relay mode and disenabling the second relay mode when there is no communication failure in the first communication path, and disenabling the first relay mode and enabling the second relay mode when there is a communication failure in the first communication path. A communication control section controls communication based on either the first relay mode or the second relay mode that is enabled by the relay mode controlling section.
