Glass Defect Detection and Optimized Cutting Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing glass manufacturing methods face challenges in minimizing quality-related losses due to gaps between tolerance limits and customer-specified quality standards, leading to non-quality losses or defects in glass sheets.
Innovation Solution
A method and system that involve detecting defects in glass ribbons before cutting, generating a map of glass attributes including defect positions and severity criteria, and using a computer system to create an optimized cutting layout based on this information, allowing customers to access relevant data for efficient cutting procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If glass sheets are cut according to standard tolerance limits, then manufacturing process is simple, but quality-related losses increase due to gaps between tolerance limits and customer standards
Solution Approach 1:
The system performs preliminary defect detection and mapping on glass ribbons before cutting into sheets. Defect information is stored in a database and made accessible to customers who can then plan cutting layouts in advance to avoid defects, reducing glass rejection while maintaining manufacturing simplicity
Solution Approach 2:
The invention implements a feedback mechanism where defect data from glass ribbons is captured, stored, and provided back to customers. This feedback enables customers to optimize cutting layouts based on actual defect locations, resolving the contradiction between simple cutting processes and quality losses
2Productivity
If comprehensive defect information is provided to customers, then cutting optimization improves, but information security and data management complexity increase
Solution Approach 1:
The system introduces an intermediary database access mechanism that provides defect information to customers in a controlled manner. The database stores comprehensive defect data and allows customers to retrieve information needed for cutting optimization without exposing the entire system, balancing productivity improvement with manageable complexity
Solution Approach 2:
Instead of providing direct access to the entire defect management system, the invention creates simplified copies or representations of defect information that customers can use for cutting layout optimization. This reduces the complexity burden on customers while maintaining cutting efficiency benefits
