Board Production Error Handling by Operator Authority Level
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In board production lines, inexperienced operators may inadvertently cause further problems by attempting to implement complex solutions, and existing learning systems do not differentiate between the effectiveness of solutions based on the operator's skill level, leading to inefficiencies in problem resolution.
Innovation Solution
A board production management device that includes a solution memory section, authority authenticating section, and effectiveness-rate learning section to authenticate worker authority levels and adjust the effectiveness rate of solutions accordingly, ensuring only executable solutions are implemented by operators of matching or higher authority levels, and prioritizing high-precision solutions by adjusting learning coefficients based on worker expertise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple candidate solutions are provided for problem events, then the effectiveness of countermeasure operations can be improved, but inexperienced operators may implement inappropriate solutions and cause further problems
Solution Approach 1:
The patent applies local quality by providing different information to different operators based on their skill level. Experienced operators receive comprehensive solution information including multiple candidate solutions and their effectiveness, while inexperienced operators receive simplified guidance with pre-selected appropriate solutions. This differentiated information provision ensures that each operator receives exactly the level of detail and complexity they can effectively utilize, preventing inexperienced operators from implementing inappropriate solutions while still providing comprehensive support to experienced operators.
Solution Approach 2:
The patent changes the parameter of information provision based on operator skill level. The system adjusts the amount, type, and complexity of solution information provided according to the operator's experience. For inexperienced operators, the system filters and prioritizes information to show only the most appropriate solutions, while for experienced operators, the system provides full details including multiple candidate solutions and their effectiveness ratings. This dynamic parameter adjustment resolves the contradiction by adapting the information provision to the operator's capability.
2Quantity of substance
If learning systems accumulate all solutions equally, then comprehensive knowledge is built, but ineffective solutions from inexperienced operators pollute the knowledge base
Solution Approach 1:
The patent applies local quality to the knowledge base by creating different storage regions or weighting schemes for solutions from different operator skill levels. Solutions from experienced operators are stored with higher weight or in a premium category, while solutions from inexperienced operators are either stored with lower weight or subjected to additional validation. This differentiated storage approach allows the system to accumulate comprehensive knowledge from all operators while maintaining high precision in the effectiveness rates by giving more credibility to solutions from experienced operators.
Solution Approach 2:
The patent implements feedback mechanisms where the effectiveness of each solution is tracked and used to update future recommendations. When a solution is implemented, the system monitors whether it successfully resolves the problem and uses this feedback to adjust the effectiveness rating. Solutions from experienced operators that prove effective receive higher ratings and are more likely to be recommended, while ineffective solutions or those from inexperienced operators that fail to resolve problems receive lower ratings. This feedback loop ensures that the knowledge base continuously improves in precision while accumulating comprehensive experience.
3Loss of information
If all solutions are presented to operators, then complete information is available, but operators cannot quickly identify the most appropriate solution
Solution Approach 1:
The patent applies segmentation by dividing the solution information into hierarchical levels or categories. The system segments solutions based on their effectiveness, applicability to different problem types, and suitability for different operator skill levels. This segmentation allows the interface to display only the most relevant solutions first, while maintaining access to the complete solution set. Operators can quickly identify appropriate solutions from the prioritized display, and if needed, access additional solutions through expanded views, thus reducing time to identify appropriate solutions without losing information completeness.
Solution Approach 2:
The patent applies preliminary action by pre-processing and pre-ranking solutions before they are presented to operators. The system automatically evaluates each solution's effectiveness, applicability, and suitability based on historical data and operator profiles, then pre-arranges them in an optimized presentation order. This preliminary ranking and filtering action occurs in the background, so when operators view the solutions, the most appropriate ones are already positioned for quick identification. This eliminates the need for operators to manually evaluate all solutions, significantly reducing the time to identify appropriate solutions while maintaining complete information availability.

AI summary
A board production management device for managing a board production line including a solution memory section for linking and storing a problem event that may occur in a board production line and that requires a countermeasure operation, a solution to serve as the countermeasure operation, and a set authority level set for a worker who may implement the solution; an solution memory section for authenticating the authority level of a worker who implements the countermeasure operation; and a solution notification section for separately reporting, when a problem event occurs, an executable solution corresponding to a set authority level equal to or less than the authority level, and an unexecutable solution corresponding to a set authority level exceeding the authority level.
