Solution Overview

Problem

The current process for checking changes in wire harness product drawings is inefficient, leading to increased steps and a risk of missing changes during visual observation, particularly in the context of frequent design changes and large volumes of documentation in the automotive industry.

Innovation Solution

An analysis device and method that compares attribute data and non-corresponding graphic data between initial and revised product drawings, using a control unit to display matching and non-matching data in distinguishable colors, facilitating the extraction of changes and preventing oversight.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If visual observation comparison is used to check changes in product drawings, then the analyst can review the drawings, but the number of steps increases and changes may be missed

Engineering Contradiction:

Improvechange detection accuracyVSAvoidchecking process complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical visual observation process with an automated computer-based image processing system. The analysis device captures images of product drawings, extracts graphic data automatically, and performs comparative analysis without requiring manual visual inspection, thereby eliminating the trade-off between reliability and complexity

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent creates digital copies of product drawings in the form of graphic data that can be stored, processed, and compared computationally. By converting physical drawings into digital representations, the system enables automated change detection without the limitations of manual visual comparison

Inventive Principle:

Principle #26Copying

2Measurement precision

If manual visual comparison of product drawings is performed, then changes can be identified, but the time required increases significantly

Engineering Contradiction:

Improvechange extraction completenessVSAvoidchecking time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent substitutes manual visual comparison with automated image processing and graphic data extraction. The control unit automatically compares graphic data between different product drawings, identifying changes instantaneously without the time consumption of manual inspection while maintaining complete change extraction

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system performs self-service by automatically capturing, processing, and comparing product drawing images without human intervention. The analysis device independently extracts graphic data, identifies changes, and presents results, eliminating the time loss associated with manual analyst work

Inventive Principle:

Principle #25Self-service

3Reliability

If detailed comparison of all drawing elements is performed, then all changes are captured, but the effort and complexity increase

Engineering Contradiction:

Improvechange detection reliabilityVSAvoidchecking effort

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent segments the product drawing into distinct graphic data elements that can be independently extracted and compared. By dividing the drawing into manageable graphical components, the system achieves comprehensive change detection while reducing the operational effort through automated processing of segmented elements

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent replaces the manual effort of detailed comparison with automated graphic data extraction and comparison algorithms. The control unit systematically analyzes all drawing elements without human fatigue or oversight, maintaining high reliability while minimizing checking effort

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
