Processing Device Network for Reliable Sequential Process Execution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In systems where multiple devices perform sequential processes, errors can lead to wasted processes and the need for device restoration, compromising the reliability of completing a series of processes.
Innovation Solution
A system where processing devices are connected to transmit information and execute processes based on confirmation from other devices that have completed the process normally, ensuring all devices receive and confirm the process request from an external device before proceeding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If devices sequentially perform processes without confirmation, then process execution speed is improved, but reliability of completing the series of processes deteriorates due to errors causing wasted processes and restoration requirements
Solution Approach 1:
Each processing device performs a determination action in advance (before executing the predetermined process) to check whether all other devices have completed their processes. This preliminary check prevents wasted processes and ensures reliable completion of the series of processes while maintaining sequential execution efficiency.
2Productivity
If devices execute processes without checking other devices' status, then process efficiency is improved, but process waste increases when errors occur
Solution Approach 1:
Each processing device receives feedback information from other devices regarding their process completion status. Based on this feedback, each device determines whether to proceed with its predetermined process, thereby avoiding process execution that would result in waste due to subsequent errors.
3Reliability
If a confirmation mechanism is added to verify process completion, then reliability of completing processes is improved, but device complexity increases
Solution Approach 1:
Each processing device independently performs the determination of whether all other devices have completed their processes, without requiring a centralized control mechanism. This self-service approach maintains reliability while minimizing the increase in device complexity.
