Solution Overview

Problem

Existing circuit forming methods using curable resin and conductive fluid are prone to errors that can disrupt the process, leading to inefficiencies and increased downtime, especially when operations are conducted outside regular working hours.

Innovation Solution

A circuit forming device and method that categorizes errors as automatic release or non-release errors, allowing for automatic re-execution of specific errors during the formation process, thereby minimizing downtime and ensuring proper circuit formation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If automatic error release and re-execution is implemented, then productivity is improved by reducing downtime and manual intervention, but device complexity increases due to the need for error classification and automatic re-execution control mechanisms

Engineering Contradiction:
Improvecircuit formation efficiencyVSAvoiderror management system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The error management system is segmented into distinct categories: automatic release errors and non-release errors. This segmentation allows the system to handle different error types differently, enabling automatic re-execution for recoverable errors while maintaining manual control for critical errors, thus improving productivity without overwhelming complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary classification of errors into automatic release and non-release categories before execution. By pre-defining which errors can be automatically recovered and which require manual intervention, the system prepares the appropriate response in advance, enabling faster error handling and reducing downtime

Inventive Principle:
Principle #10Preliminary action

2Reliability

If all errors are manually handled, then reliability is maintained through human judgment, but loss of time increases due to manual intervention requirements

Engineering Contradiction:
Improveerror handling accuracyVSAvoiddowntime during error occurrence
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The error handling approach is made dynamic by automatically selecting different handling strategies based on error type. For automatic release errors, the system dynamically re-executes the failed operation without human intervention, significantly reducing downtime while maintaining reliability through the predefined error classification framework

Inventive Principle:
Principle #15Dynamics

AI summary

A circuit forming method for forming a circuit with a curable resin and a conductive fluid, the method including a setting step of setting errors that occur during a circuit forming work to an automatic release error and a non-release error for each type of error, the automatic release error being to be automatically released, and the non-release error being not to be automatically released, a determination step of determining whether an error has occurred in work when the circuit is formed, and a re-execution step of automatically re-executing work determined that the error has occurred in the determination step, in a case where the error of the work is set to the automatic release error in the setting step.
