Solution Overview

Problem

In the design of printed circuit boards, manual correction of line segment defects such as intersections and discontinuities is necessary due to differences in metric units between mechanical and PCB sectors, leading to inefficiencies and resource wastage.

Innovation Solution

A method using computer-executable circuit layout software to automatically detect and correct line segment defects by deleting intersecting segments and connecting discontinuous ones, allowing for the use of different metric units without human intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual correction of line segment defects is performed, then line segment defects are corrected, but human resources are consumed and working process is prolonged

Engineering Contradiction:

Improveline segment defect correctionVSAvoidworking process duration

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs automatic self-correction of line segment defects through computer-executable instructions that detect intersections and discontinuities, and automatically modify the circuit diagram without requiring human intervention, thereby eliminating manual labor and reducing working process duration

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The manual mechanical correction process is replaced by an automated computational system that uses algorithms to detect line segment defects and apply corrections, substituting human manual operations with automated mechanical/computational processes

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If different metric units are used by different sectors, then each sector can use its preferred unit, but line segment intersections and discontinuities occur

Engineering Contradiction:

Improvemetric unit flexibilityVSAvoidcircuit diagram completeness

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system acts as an intermediary that receives circuit diagrams with different metric units, automatically detects the unit differences, converts or adjusts the line segments accordingly, and outputs a corrected circuit diagram that maintains completeness despite the use of different metric units by different sectors

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system dynamically changes the parameters of line segments (such as coordinates, lengths, or positions) based on the metric units used, automatically adjusting these parameters to resolve intersections and discontinuities that arise from unit differences between mechanical and PCB sectors

Inventive Principle:

Principle #35Parameter changes

AI summary

A method for automatically modifying a frame of a circuit diagram is applicable for a computer-executable circuit layout software, which determines intersection or discontinuity of line segments generated after a diagram is converted through using a program, and automatically corrects the diagram to output a complete circuit diagram, so as to enhance the convenience of reading and determining the circuit diagram, and to simplify manual inspection procedures, and thus the working process is accelerated.
