Solution Overview

Problem

Current systems for assisting circuit-substrate-related work in electric circuit production lack effectiveness in determining and implementing improvement actions for quality deterioration, leading to suboptimal maintenance and reliability in electric circuit quality.

Innovation Solution

A circuit-substrate-related-work assisting device and method that includes a quality judging portion, an improvement-action determining portion, an action notifying portion, and an action-completion-information receiving portion to assess and address quality deterioration by determining appropriate improvement actions and notifying both machines and operators, ensuring effective implementation and monitoring of these actions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If quality inspection and improvement action notification are implemented, then work quality can be maintained, but system complexity increases

Engineering Contradiction:
Improvework qualityVSAvoidassisting device structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The assisting device is divided into four distinct functional portions: a quality judging portion that assesses work quality, an improvement-action determining portion that identifies corrective actions, an action notifying portion that communicates recommendations, and an action-completion-information receiving portion that verifies implementation. This segmentation allows each component to perform its specific function independently, making the overall system more manageable and maintainable while ensuring comprehensive quality monitoring

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The assisting device integrates multiple functions into a single unified system that can handle quality assessment, improvement action determination, notification, and completion verification. This multi-functional approach consolidates what could be separate systems into one cohesive device, reducing overall system complexity while maintaining comprehensive quality management capabilities

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If improvement actions are determined and notified, then quality deterioration can be addressed, but time for action implementation is required

Engineering Contradiction:
Improvequality deterioration responseVSAvoidaction implementation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The quality judging portion continuously monitors work quality in real-time, identifying quality deterioration trends before they result in defective products. The improvement-action determining portion then proactively recommends corrective actions based on the detected trends, enabling operators to address issues before they escalate. This preliminary action approach prevents quality problems rather than merely reacting to them, reducing the time needed for corrective implementation

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The action-completion-information receiving portion receives feedback from operators or the work-performing device about whether improvement actions have been implemented. This feedback loop allows the system to verify whether corrective actions were taken and to continue monitoring quality trends to assess whether the actions were effective. The continuous feedback mechanism ensures timely response to quality issues while tracking the implementation status of improvement actions

Inventive Principle:
Principle #23Feedback

AI summary

A circuit-substrate-related-work assisting device and method with high utility are provided. The circuit-substrate-related-work assisting device and method for assisting a circuit-substrate-related work performed by a circuit-substrate-related-work performing machine on a circuit substrate that constitutes an electric circuit are arranged as follows: a judgment as to a change in work quality of the circuit-substrate-related-work performing machine is made (158); an improvement action for improving the work quality is determined where a degree of deterioration of the work quality exceeds a prescribed degree (160); the determined improvement action is notified to at least one of the circuit-substrate-related-work performing machine and an operator of the circuit-substrate-related-work performing machine (162); at least one of the circuit-substrate-related-work performing machine and the operator of the circuit-substrate-related-work performing machine receives action-completion information that is information as to completion of the notified improvement action (166); and a judgment as to a change in the work quality before and after the completion of the improvement action is made, conditionally on reception of the action-completion information. It is possible to appropriately confirm improvement effects of the quality by the implemented improvement action.
