Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face increased communication delay and load when multiple devices transmit data simultaneously, leading to system complexity and inefficiency due to the need for additional software and dynamic priority changes, which are not universally shared, and static design challenges from varying power and usage patterns.
Innovation Solution
A communication apparatus with an electronic control unit that manages transmission timing, measures actual transmission time, and adjusts next transmission timing based on whether the time exceeds a specified period, thereby leveling network load and reducing maximum delay time with minimal system burden.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If dynamic priority change method is used to reduce communication delay, then communication delay of low priority data is suppressed, but system configuration becomes complicated and burden increases
Solution Approach 1:
The invention applies dynamics by making the transmission timing adjustable rather than fixed. The electronic control unit dynamically determines transmission timing based on actual transmission time measurements, allowing the system to adapt to varying communication loads without requiring complex priority management software or protocols.
Solution Approach 2:
The communication apparatus performs self-adjustment by automatically measuring its own transmission time and modifying its next transmission timing based on whether the measured time exceeded the specified time. This self-service mechanism eliminates the need for external priority management or complex software interfaces.
2Productivity
If static transmission timing is used to level communication load, then network load is balanced, but optimal resource utilization is difficult to achieve due to power and usage variations
Solution Approach 1:
The invention replaces static transmission timing with dynamic adjustment. The electronic control unit continuously adapts transmission timing based on actual transmission time measurements, allowing the system to optimize communication resource utilization in real-time while maintaining balanced network load, regardless of power or usage variations.
Solution Approach 2:
The invention implements feedback by measuring the actual transmission time and using this information to determine the next transmission timing. This closed-loop control allows the system to respond to actual communication conditions and adjust accordingly, achieving both optimal resource utilization and reduced communication delay.
3Speed
If multiple communication apparatuses transmit simultaneously, then data transmission speed increases, but communication load increases and causes communication delay
Solution Approach 1:
The invention uses periodic transmission with adaptive timing adjustment. Instead of continuous or simultaneous transmission, the electronic control unit schedules transmissions periodically but dynamically adjusts the timing based on actual transmission time measurements, preventing overload while maintaining efficient data transmission speed.
Solution Approach 2:
The system dynamically adjusts transmission timing to balance speed and delay. By making transmission timing adaptive rather than fixed or simultaneous, the system allows multiple apparatuses to transmit efficiently while preventing network overload and communication delay.

AI summary
A communication apparatus includes an electronic control unit configured to manage transmission timing of predetermined data to the network, transmit the data to the network based on the transmission timing, measure an actual transmission time, determine whether the actual transmission time exceeds a specified transmission time, when the transmitted data is predetermined control object data, when determination is made that the actual transmission time is equal to or less than the specified transmission time, set next transmission timing of the control object data to be the predetermined period, and when the transmitted data is the control object data, when determination is made that the actual transmission time exceeds the specified transmission time, delay next transmission timing of the control object data by a predetermined waiting time with respect to the predetermined period.
