Communication Node Conflict Resolution via Dynamic Slot Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in setting transmission timing for multiple nodes in a data transmission system, especially when assembling outboard motors and other devices, leading to communication conflicts.
Innovation Solution
An information communication device with multiple nodes, each assigned a specific transmission slot within a synchronized communication cycle, includes a conflict detector and a transmission area setter that adjusts slots based on discrimination information to prevent conflicts, using both static and dynamic transmission areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If transmission timing is separately set for each terminal station to prevent communication conflicts, then communication reliability is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The system enables nodes to automatically detect transmission conflicts and adjust their own transmission slots without external intervention. Each node monitors the communication bus, detects conflicts with other nodes of the same type, and autonomously changes its transmission slot to resolve the conflict, eliminating the need for manual network configuration
Solution Approach 2:
The system implements a feedback mechanism where nodes monitor the communication bus for transmission conflicts. When a conflict is detected (indicated by error signals from other nodes), the affected node receives feedback information and automatically adjusts its transmission slot in response to this feedback, creating a closed-loop conflict resolution system
2Stability of the object's composition
If transmission slots are fixed in the static transmission area, then communication stability is improved, but adaptability deteriorates
Solution Approach 1:
The system combines a static transmission area with fixed slots for stability with a dynamic adjustment capability that allows nodes to change their transmission slots when conflicts are detected. The transmission slot assignment transitions from a static configuration to a dynamic one based on real-time conflict detection, maintaining overall system stability while enabling necessary adaptability
Solution Approach 2:
The communication cycle is segmented into a static transmission area with predetermined slots and a dynamic adjustment mechanism. The static area provides stable, predictable transmission timing, while the dynamic component allows individual nodes to adapt their slots within the structured framework of the communication cycle

AI summary
An information communication device for communicating information among a plurality of components includes a plurality of nodes, each being of a particular node type that corresponds to a particular transmission slot of a plurality of transmission slots. Each transmission slot is formed from a communication cycle that has a prescribed time period. The plurality of transmission slots are synchronized with one another. The communication cycle includes a static transmission area and a dynamic transmission area, where the static transmission area includes the plurality of transmission slots that correspond to the node types. The dynamic transmission area is adapted to transmit information. Each of the plurality of nodes includes a conflict detector that determines when a transmission conflict occurs as a result of nodes of the same node type beginning transmission using the same transmission slot. Each of the plurality of nodes also includes a transmission area setter for changing the transmission slots in the static transmission area based upon information transmitted in the dynamic transmission area.
