Wire Harness Analyzer for Drawing Change Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The current process for designing wire harnesses in vehicle production is inefficient, requiring frequent changes to jig plate and route layouts, leading to increased documentation and manual comparison of product drawings, which can result in missed changes during the design verification process.
Innovation Solution
An analyzer and analysis 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 distinct colors, facilitating the extraction of changes and preventing oversight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If visual observation comparison method is used to check changes in product drawings, then the analyst can identify modifications, but the number of checking steps increases and changes may be missed
Solution Approach 1:
The patent replaces the mechanical visual observation method with an automated computer-based image processing system. The analyzer captures product drawing images, performs automatic comparison between different versions, and highlights changes using color coding (yellow for added elements, red for removed elements). This substitution eliminates manual checking steps while improving both speed and reliability of change detection.
Solution Approach 2:
The patent introduces an intermediary comparison system that acts as a mediator between different product drawing versions. The analyzer serves as an intermediary tool that objectively compares images, extracts difference information, and presents it in a standardized format. This intermediary approach prevents human error and inconsistency in visual comparison while maintaining comprehensive change detection.
2Adaptability or versatility
If frequent changes are made to jig plate and route layouts, then the wire harness design adapts to vehicle specifications, but the amount of documentation and manual comparison work increases
Solution Approach 1:
The patent enables the documentation system to serve itself by automatically generating comparison reports from image data. The analyzer extracts change information directly from product drawing images without requiring manual documentation creation. This self-service approach reduces the complexity of documentation management while supporting frequent design changes, as the system automatically tracks and records all modifications.
Solution Approach 2:
The patent uses image copying and digital reproduction of product drawings to manage design variations. Instead of creating separate physical documentation for each design version, the system captures images of drawings and uses digital copies for comparison and analysis. This copying approach simplifies documentation management while maintaining adaptability to frequent design changes.
Data Source
AI summary
An analyzer refers to information included in a recorded product drawing, builds a part of or the entire wire harness by drawing corresponding graphic data of each member constituting the wire harness, adds non-corresponding graphic data to the built wire harness, and displays the product drawing.
