Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual inspection methods are used to identify tire sidewall markings, then the process is simple to implement, but the method is prone to errors and cumbersome
Solution Approach 1:
The patent replaces manual visual inspection with an automated image processing system that captures images of tire sidewall markings using a camera or sensor, processes the images through software algorithms, and automatically identifies marking characteristics. This substitution eliminates human error while maintaining operational simplicity through automated workflows.
Solution Approach 2:
The patent creates digital copies (images) of the tire sidewall markings instead of requiring direct human observation. The image processing system captures, stores, and analyzes digital representations of the markings, enabling reliable identification without direct mechanical or manual intervention with the physical tire.
2Measurement precision
If a turntable system with centering blocks is used to align tires, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The centering blocks are designed to automatically self-align with the tire's inner diameter, eliminating the need for complex manual positioning mechanisms. The blocks slide along radial axes and naturally find their correct position based on the tire dimensions, providing precise alignment through self-service rather than complex control systems.
Solution Approach 2:
The turntable system with adjustable centering blocks serves multiple functions: it centers tires of various diameters, rotates the tire to different angular positions, and positions the tire for image capture. This multi-functionality reduces the need for separate devices for each operation, managing complexity through consolidation.
3Reliability
If image processing systems are used to examine tire sidewalls, then the reliability of identification is improved, but the ease of operation decreases
Solution Approach 1:
The image processing system provides automated feedback through the display device, showing processed images and identification results to the operator. This feedback loop allows operators to verify results quickly without manually examining tires, maintaining ease of operation while significantly improving reliability through automated analysis.
Solution Approach 2:
The patent replaces manual inspection operations with automated image capture and processing. The system automatically captures images, processes them through algorithms, and presents results, eliminating the need for operators to manually examine and interpret tire markings while maintaining simple interaction through display-based interfaces.
