Engineering Contradiction Analysis
1Measurement precision
If electronic systems or complex algorithms are used for coordinate transformation, then transformation accuracy is improved, but device complexity and computational resources increase
Solution Approach 1:
The patent replaces electronic computational systems with a purely mechanical coordinate transformation device. The mechanical linkages, sliders, and rotating elements physically perform the mathematical transformation from Cartesian to spherical coordinates through geometric relationships, eliminating the need for computers, processors, or complex electronic algorithms while maintaining transformation accuracy.
Solution Approach 2:
The patent employs spherical geometric elements and curved mechanical paths to naturally represent spherical coordinates. The mechanical structure uses arcs, circles, and spherical intersections to map Cartesian coordinates to spherical coordinates through pure geometry, leveraging the inherent relationship between linear and angular measurements in spherical space.
2Productivity
If electronic processing systems are used, then transformation speed is improved, but power consumption and system cost increase
Solution Approach 1:
The patent replaces power-consuming electronic processing with passive mechanical motion. The transformation occurs in real-time as mechanical components move and interact through linkages and geometric constraints, requiring no electrical power during the transformation operation itself, only minimal power to actuate the input coordinates.
Solution Approach 2:
The mechanical system performs the transformation automatically through its own motion and geometric relationships. As the input coordinates are mechanically imposed on the system, the transformation occurs self-driven through the mechanical architecture without requiring external computational power or active electronic processing.
3Measurement precision
If complex electronic systems are used, then transformation precision is improved, but reliability and ease of maintenance worsen
Solution Approach 1:
The patent replaces fragile electronic systems with robust mechanical components. The transformation precision is achieved through precision-machined mechanical parts with fixed geometric relationships, which are inherently more reliable in harsh environments and easier to maintain than electronic systems with no moving parts but sensitive circuits and software.
Solution Approach 2:
The patent uses uniform mechanical materials and consistent manufacturing tolerances throughout the device. All critical dimensions are achieved through the same precision machining processes, ensuring homogeneous quality and reliability across all transformation elements without the variability introduced by different electronic components and software versions.
