Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If step-by-step conveying method with roller tables is used, then production line can be assembled, but continuous production cannot be achieved and glass breakage occurs
Solution Approach 1:
The patent implements continuous conveying of glass products through the entire production line using roller tables that run through all chambers (degreasing, drying, heating, cooling) without stopping. This eliminates the start-stop motion that causes glass breakage and achieves continuous production, directly resolving the contradiction between productivity and reliability.
2Ease of repair
If roller tables and heating tubes are replaced by dismantling production line, then maintenance can be performed, but maintenance efficiency is very low and production efficiency is greatly affected
Solution Approach 1:
The production line is divided into independent modular chambers (degreasing chamber, drying chamber, heating chamber, cooling chamber) that can be accessed separately. Roller tables and heating tubes in each chamber can be maintained without dismantling the entire production line, allowing maintenance to be performed on specific sections while other sections continue operating, thus maintaining high productivity during maintenance.
Solution Approach 2:
The patent introduces removable sealing doors and inspection holes as intermediaries that allow maintenance personnel to access roller tables and heating tubes without complete dismantling. These intermediary access points enable selective maintenance of specific components while the rest of the production line remains operational.
3Ease of manufacture
If square working chamber is used, then chamber structure is simple, but stable ambient temperature cannot be provided and yield decreases
Solution Approach 1:
The patent employs cylindrical heating chambers instead of square chambers. The cylindrical shape provides more uniform heat distribution and stable ambient temperature throughout the chamber, which is critical for high-yield vacuum glass production. The curved geometry eliminates dead zones and improves thermal convection patterns compared to angular chamber designs.
4Device complexity
If one-step vacuum glass production line is used, then production process is simplified, but continuous production cannot be achieved
Solution Approach 1:
The production line is segmented into multiple functional chambers (degreasing chamber, drying chamber, heating chamber, cooling chamber) connected in sequence. Each chamber performs a specific function and glass products move continuously through all chambers on roller tables, enabling continuous production while maintaining relatively simple device structure through modular design.
