Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If device status verification is performed according to a preset interval, then the system can detect device participation and detachment, but the detection delay increases and prompt status detection becomes impossible
Solution Approach 1:
The patent implements a feedback mechanism where devices actively report their status (participation and detachment) to the management device through message transmission. This real-time feedback replaces periodic verification, enabling immediate status detection without time delays while maintaining detection accuracy.
Solution Approach 2:
Devices perform preliminary actions by proactively notifying the management device of their status changes before the next verification interval begins. This prevents detection delays by ensuring status information is available immediately upon change, rather than waiting for the next preset verification time.
2Reliability
If a management device is selected from network nodes to manage the group, then network node group formation and maintenance is achieved, but processing time for role determination and status detection increases
Solution Approach 1:
The patent applies preliminary action by having devices determine management device roles during the initial network formation phase before full operation begins. This preliminary role determination avoids time-consuming selection processes during operation, enabling swift status detection and management from the start of network activity.
Solution Approach 2:
Network devices autonomously determine their own roles and capabilities without requiring complex centralized coordination. Each device self-identifies as a management device or managed device based on preset conditions, eliminating time-consuming role assignment negotiations while ensuring reliable network management structure.
3Ease of operation
If communication parameter configuration is performed automatically in ad hoc networks, then user operation complexity is reduced, but the lack of device status management mechanisms prevents initiation of communication among multiple devices
Solution Approach 1:
The patent introduces a management device as an intermediary that coordinates communication parameter configuration among multiple devices. This intermediary maintains device status information and manages the configuration process, enabling reliable communication initiation while keeping user operations simple through automated backend coordination.
Solution Approach 2:
The management device receives feedback from managed devices about their status and capabilities, then coordinates parameter configuration accordingly. This feedback mechanism ensures that communication parameters are reliably configured for all participating devices while maintaining ease of operation through automated processes.

AI summary
In a communication apparatus on a network where communication apparatuses perform direct communication with each other, a network management apparatus for managing the network based on message information transmitted and received on the network is determined. When the communication apparatus itself is determined as the network management apparatus, the apparatus collects information indicating device capabilities from other communication apparatuses. On the other hand, the communication apparatus receives information indicating device capabilities from another communication apparatus when the other communication apparatus is determined as the network management apparatus.
