Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional detection methods are used for glass fine particle deposit deformation, then the production process continues without interruption, but the response to deformation is delayed and quality control is insufficient
Solution Approach 1:
The imaging device captures images of the deposition surface in real-time during the glass fine particle deposit formation process, enabling early detection of deformations before they affect final product quality. This preliminary monitoring allows for immediate corrective actions.
Solution Approach 2:
The system establishes a closed-loop feedback mechanism where the imaging device continuously monitors the deposition surface, the image processing unit analyzes deformation in real-time, and the information is fed back to control the production process, enabling dynamic adjustment to maintain quality standards.
2Measurement precision
If real-time imaging and analysis are implemented, then deformation detection precision is improved, but the device complexity increases
Solution Approach 1:
The system replaces complex mechanical measurement devices with an optical imaging system and computational image processing. The imaging device captures visual information of the deposition surface, and software algorithms automatically analyze deformation, substituting mechanical complexity with optical and computational simplicity.
Solution Approach 2:
The imaging device creates a visual copy (image) of the deposition surface, which is then analyzed by the image processing unit. This copying approach allows for non-contact, high-precision measurement without physically interacting with the deposit, simplifying the measurement system while maintaining high accuracy.
3Manufacturing precision
If comprehensive quality monitoring is implemented, then production quality improves, but the processing time and computational load increase
Solution Approach 1:
The image processing unit focuses on detecting specific deformation patterns (tip deformation, rotationally asymmetric deformation, side surface deformation) rather than analyzing every possible parameter. This targeted approach maintains high quality control while reducing unnecessary computational overhead.
Solution Approach 2:
The system implements automated image processing and deformation detection algorithms that operate independently without requiring manual intervention. The image processing unit automatically analyzes captured images, identifies deformations, and provides results, enabling the system to self-monitor quality without adding operational complexity or slowing production.

AI summary
An apparatus for producing a glass preform is an apparatus by pulling up a starting rod while the starting rod is rotated around an axis and glass fine particles generated by a burner are deposited in an axial direction of the starting rod. The apparatus for producing a glass preform includes an imaging device that acquires a deposition surface image by imaging a deposition surface of a glass fine particle deposit deposited on the starting rod, and an image processing unit that detects an edge shape of the deposition surface from the deposition surface image acquired using the imaging device to judge quality of the glass fine particle deposit by quantifying a degree of deformation of the edge shape.
