A setup device with precise geometric characteristics and predefined shapes is used to facilitate the calibration of image acquisition devices and configuration of robotic members, featuring parallel walls and a central reference for efficient positioning and alignment, allowing for faster and more precise setup of tyre checking apparatuses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual calibration and trial-and-error methods are used for setting up tyre checking apparatuses, then the setup process is flexible and adaptable, but the setup time is significantly increased and precision is reduced
Solution Approach 1:
The patent applies preliminary action by pre-configuring the setup device with predefined geometric characteristics and shapes before the actual calibration process. The device includes pre-defined wall positions, central reference markers, and standardized geometric features that eliminate the need for trial-and-error adjustments during setup, thereby reducing setup time while maintaining precision
Solution Approach 2:
The setup device acts as an intermediary between the operator and the tyre checking apparatus. It provides a standardized interface with predefined geometric features that mediate the calibration process, enabling precise and rapid setup without requiring manual trial-and-error adjustments of the apparatus components
2Reliability
If manual calibration methods are used, then the setup process is simple in terms of device complexity, but the reliability and repeatability of setup operations deteriorate
Solution Approach 1:
The patent applies parameter changes by transforming the setup process from manual, variable human operations to a standardized process based on fixed geometric parameters. The setup device incorporates predefined geometric characteristics (specific dimensions, angles, and positions) that ensure consistent, reliable, and repeatable setup operations across different installations
Solution Approach 2:
The setup device is segmented into distinct functional components with predefined geometric characteristics, including separate wall structures, central reference markers, and calibration features. This segmentation allows each component to contribute specifically to the overall reliability and repeatability of the setup process
3Productivity
If traditional setup methods are used, then the apparatus can be set up with minimal equipment, but the speed of setup operations is significantly reduced
Solution Approach 1:
The setup device is designed as a universal, multi-functional tool that combines multiple calibration and positioning functions in a single integrated unit. It can simultaneously provide reference markers, geometric constraints, and alignment features for different components of the tyre checking apparatus, thereby accelerating setup speed without requiring multiple separate tools
