1Loss of time

If transmission time is corrected without optimizing communication parameters, then transmission timing is improved, but communication quality deteriorates

Engineering Contradiction:

Improvetransmission timingVSAvoidcommunication quality

Core Design Contradiction:

Loss of timeVSReliability

Solution Approach 1:

The patent changes communication parameters (transmission interval, transmission time) based on network state analysis. The determination unit analyzes time information from frames to determine if parameter correction is needed, and the correction notification unit notifies target devices of optimized parameters, thereby improving communication quality while maintaining timing accuracy.

2Reliability

If communication parameters are adjusted to optimize network quality, then communication quality is improved, but system complexity increases

Engineering Contradiction:

Improvecommunication qualityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The correction device automatically determines whether parameter correction is needed and identifies which devices need correction without manual intervention. The determination unit autonomously analyzes time information from received frames and decides if communication parameters need optimization, reducing the need for complex manual configuration while maintaining high communication quality.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system uses feedback from time information in transmitted frames to continuously optimize communication parameters. The correction device receives frames, analyzes their time information, determines if parameters need correction, and notifies target devices of optimized parameters, creating a closed-loop feedback system that automatically improves communication quality without increasing overall system complexity.

Inventive Principle:

Principle #23Feedback

AI summary

A correction device included in a communication system is configured to determine whether a communication parameter, which is set in a transmission setting for transmitting a frame in at least one target device, needs to be corrected based on time information included in a frame. The correction device is configured to adjust the communication parameter to suppress a deterioration in a communication quality in response to determining that the communication parameter needs to be corrected. Then, the correction devices is configured to notify the at least one target device of a new communication parameter that has been adjusted.
