Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing screen image capturing technology is used, then the capturing process is simple, but the three-dimensional display effect of flexible screens cannot be accurately captured
Solution Approach 1:
The patent transforms the image capturing process from two-dimensional planar coordinates to three-dimensional spatial coordinates by introducing depth information through bending parameter measurement. The flexible screen's curved surface is modeled in 3D space, and pixel points are mapped from 2D screen coordinates to 3D spatial coordinates (x, y, z) that reflect the actual curved geometry, thereby accurately capturing the three-dimensional display effect.
Solution Approach 2:
The patent introduces bending parameters (curvature radius, bending angle) as intermediary measurements that bridge the gap between the physical curved screen and its digital representation. These parameters serve as mediators to calculate the curved surface equation and transform coordinates, enabling accurate 3D modeling without requiring complex direct 3D scanning equipment.
2Manufacturing precision
If three-dimensional spatial coordinates are calculated through interpolation fitting, then the accuracy of curved surface representation is improved, but the computational complexity increases
Solution Approach 1:
The patent performs preliminary measurement of bending parameters (curvature radius and bending angle) before conducting the full coordinate transformation. By pre-acquiring these key geometric parameters, the system can directly construct the curved surface equation without requiring extensive real-time computational fitting during the image capturing process, thus reducing computational complexity while maintaining precision.
Solution Approach 2:
The patent changes the representation parameters from direct coordinate geometry to physical bending parameters (curvature radius R and bending angle θ). This parameter transformation simplifies the mathematical model of the curved surface, allowing the complex 3D geometry to be described by a few key physical parameters that are easier to measure and compute.
3Ease of manufacture
If projection from three-dimensional to two-dimensional coordinates is performed, then the image file generation is simplified, but the three-dimensional display effect information may be lost
Solution Approach 1:
The patent performs preliminary coordinate transformation from 2D screen coordinates to 3D spatial coordinates before the projection step. By pre-establishing the 3D spatial position of each pixel point based on the curved surface equation, the subsequent projection to 2D image coordinates preserves the 3D geometric relationships, preventing loss of three-dimensional display effect information while enabling standard 2D image file generation.
