Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for collecting and analyzing component mounting information are hindered by the large volume of logging data, making it difficult to acquire and compare relevant information related to trigger events during the component mounting process.
Innovation Solution
A trace assistance device and method that records and stores manipulation and operation logs, allowing for the acquisition and output of target and comparison histories related to trigger events, enabling efficient comparison and analysis of board production line operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If logging information is collected comprehensively including board number, mounting position, component name, mounting condition, actual measurement value, and acquired image, then the completeness of information is improved, but the amount of information stored increases making it difficult to acquire and compare relevant information
Solution Approach 1:
The patent segments the large volume of logging information into distinct categories: manipulation log (operator actions), operation log (machine responses), trigger event log (error occurrences), and detailed logging information (specific parameters). This segmentation allows the system to manage comprehensive information while enabling targeted retrieval by querying specific log types rather than searching through all data simultaneously.
Solution Approach 2:
The patent introduces an information management system that acts as an intermediary between the comprehensive logging information and the user. This system provides structured storage, association mechanisms between different log types, and query interfaces that translate user requests into efficient data retrieval operations, thereby simplifying the complexity of managing detailed logging information.
2Loss of information
If all types of logging information are stored in memory, then the information availability is improved, but the time required to acquire and compare relevant information increases
Solution Approach 1:
The patent implements preliminary organization of logging information by pre-categorizing data into manipulation logs, operation logs, and trigger event logs with established association relationships. When a trigger event occurs, the system can immediately retrieve associated manipulation and operation logs without performing ad-hoc searches, significantly reducing the time required to acquire and compare relevant information while maintaining full information availability.
3Measurement precision
If detailed manipulation and operation histories are recorded and associated, then the analysis capability is improved, but the data processing complexity increases
Solution Approach 1:
The patent segments the log management system into distinct functional modules: manipulation log recording, operation log recording, trigger event detection, and association management. Each module handles specific tasks independently, which maintains analysis precision through detailed recording while reducing overall system complexity through modular design and clear separation of concerns.

AI summary
A trace assistance device includes a memory section, an acquisition section, and an output section. The memory section is configured to store a manipulation log in which multiple manipulation histories of an operator with respect to a board production line are recorded, and an operation log in which multiple operation histories of the board production line actuated due to a manipulation of the operator are recorded in association with each other in a memory device. The acquisition section is configured to, when a predetermined trigger event occurs during the board work, acquire at least one target manipulation history related to the trigger event, a target operation history associated with the target manipulation history, a comparison manipulation history that is the same as or similar to the target manipulation history, and a comparison operation history associated with the comparison manipulation history from the manipulation log and the operation log stored in the memory device. The output section is configured to output an operation of the board production line recorded in the target operation history and an operation of the board production line recorded in the comparison operation history, which are acquired by the acquisition section, in a comparable manner.
