Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If glass shaping process is adjusted by operator experience, then the process can be operated, but the manufacturing precision and consistency deteriorate
Solution Approach 1:
The patent implements a closed-loop feedback system where measurement devices detect deviations of the glass shape from the desired shape, and this deviation information is fed back to automatically adjust bending process parameters. This replaces operator experience with automated feedback control, improving manufacturing precision without requiring complex human expertise.
Solution Approach 2:
The patent replaces the mechanical/system-dependent operator experience with an automated computer-controlled system. The computing device processes measurement data and automatically determines parameter adjustments, substituting human judgment with algorithmic control to achieve consistent, precise glass shaping.
2Manufacturing precision
If tighter tolerances are required for glass shapes, then manufacturing precision improves, but the difficulty of controlling the process increases
Solution Approach 1:
The automated feedback system continuously monitors glass shape deviations and adjusts bending parameters in real-time to maintain tighter tolerances. This makes achieving tight tolerances easier by providing continuous correction based on actual measurements, rather than requiring operators to manually adjust for precision.
Solution Approach 2:
The system automatically modifies bending process parameters based on measured deviations, enabling precise control of glass shape within tight tolerances. The computing device calculates optimal parameter adjustments to compensate for deviations, making tight tolerance control achievable through automated parameter optimization.
3Manufacturing precision
If automated parameter adjustment is implemented, then manufacturing precision improves, but device complexity increases
Solution Approach 1:
The computing device performs multiple functions: it receives measurement data, processes deviation information, determines parameter variations, and outputs adjusted parameters. This multi-functional integration achieves high manufacturing precision through a single automated system rather than multiple separate complex subsystems.
Solution Approach 2:
The patent replaces complex manual operation and adjustment mechanisms with an automated computing-based control system. This substitution achieves consistent manufacturing precision through algorithmic control, reducing the need for complex mechanical adjustment devices and operator expertise.

AI summary
The computer-implemented method for glass bending includes obtaining a deviation of a real shape of a glass from a desired shape of the glass, the glass is produced by a glass bending process; determining a variation of at least one parameter associated with the glass bending process, at least in part based on the deviation of the real shape from the desired shape; and adjusting the at least one parameter based on the variation for compensation of the deviation.
