Engineering Contradiction Analysis
1Manufacturing precision
If conventional bending methods are used, then the bending process can be performed with simple equipment, but the manufacturing precision and accuracy of three-dimensional bending bodies deteriorate
Solution Approach 1:
The bending control process is segmented into distinct functional modules: a data processing unit that compares coordinate systems to generate intended bending information, and a control unit that translates this information into control signals for bending elements. This segmentation allows complex 3D bending control to be managed through systematic, modular processing steps, improving accuracy without overwhelming device complexity
Solution Approach 2:
The patent replaces traditional mechanical trial-and-error bending methods with an automated control system that uses data processing and coordinate system comparison. The control unit automatically generates control signals based on intended bending information, substituting manual mechanical adjustment with automated computational control, thereby significantly improving bending precision
2Manufacturing precision
If standardized methods for describing 3D spatial structures are used, then the description process is simplified, but the ability to accurately represent complex bending geometries deteriorates
Solution Approach 1:
The patent employs a coordinate system comparison approach that effectively adds dimensional analysis to the bending description process. By comparing at least two coordinate systems to generate intended bending information, the system can accurately represent complex 3D spatial structures and bending geometries that cannot be described by standardized single-dimension methods, achieving high geometry description accuracy
3Manufacturing precision
If real-time control adjustments are implemented, then the bending accuracy is improved, but the processing time and complexity increase
Solution Approach 1:
The data processing unit performs preliminary calculations by comparing coordinate systems and generating intended bending information before the actual bending execution. This preliminary action prepares the control signals in advance, allowing the bending process to proceed with high accuracy without real-time computational delays, thus reducing processing time while maintaining precision
