Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a relay mode is adopted for communication with a single preferred mode, then device complexity is reduced, but communication reliability deteriorates due to blind spots and instability in certain scenarios
Solution Approach 1:
The patent segments communication modes into multiple mode sets, where each set contains mutually incompatible modes but modes from different sets are compatible. This segmentation allows the system to manage complexity by organizing modes into structured groups while maintaining multiple viable communication paths for improved reliability.
Solution Approach 2:
The patent changes the parameter of communication mode selection by introducing a negotiation mechanism that dynamically selects optimal modes from different sets based on channel conditions. This allows the system to adapt to varying communication environments and avoid blind spots of any single mode.
2Reliability
If multiple communication modes are combined to achieve point-to-point interconnection, then communication reliability is improved, but device complexity increases due to mutual interference between modes
Solution Approach 1:
By dividing communication modes into multiple sets with clear compatibility rules, the patent reduces the complexity of managing multiple modes. The segmentation ensures that only compatible modes from different sets are activated simultaneously, avoiding mutual interference while maintaining improved reliability through mode diversity.
Solution Approach 2:
The patent introduces a negotiation mechanism as an intermediary that manages the selection and coordination of communication modes. This intermediary handles the complexity of mode management by automatically selecting optimal compatible modes based on channel conditions, relieving the system of manual configuration complexity.
3Device complexity
If communication modes are selected without considering channel quality, then device complexity is reduced, but communication efficiency deteriorates due to suboptimal mode selection
Solution Approach 1:
The patent implements a feedback mechanism where nodes exchange response information including characteristic parameters representing channel quality. This feedback enables the negotiation mechanism to select optimal communication modes based on actual channel conditions, improving communication efficiency without significantly increasing device complexity through automated decision-making.

AI summary
Provided are a networking method, communication method, and communication system for a multi-mode communication device, a device, and a chip. The networking method includes: sending response information about available communication modes between a network access node and a to-be-connected node to the network access node, where the available communication modes are divided into a plurality of sets, and modes in each of the sets are incompatible with each other, and modes in different sets are compatible with each other; and locking an optimal mode, selected from each of the sets based on the response information, as handshake information between the two nodes when a preset negotiation result is met, such that the network access node reports corresponding routing information, and a root node updates networking routing information.
