Engineering Contradiction Analysis
1Measurement precision
If manual calibration methods are used to align digital twins with physical environments, then measurement precision can be achieved, but the process becomes tedious and time-consuming
Solution Approach 1:
The system enables automatic self-calibration by having the digital twin autonomously align with physical reference points without manual intervention. The processing system automatically receives coordinates from pucks, calculates transformations, and applies scaling and rotation to align the digital twin with the physical environment, eliminating tedious manual calibration processes.
Solution Approach 2:
The patent replaces manual mechanical alignment procedures with an automated computational system. Instead of physically measuring and manually adjusting the digital twin, the system uses coordinate data from pucks, processes this information through algorithms, and automatically applies the necessary transformations to achieve precise alignment.
2Measurement precision
If manual calibration methods are used to align digital twins with physical environments, then measurement precision can be achieved, but the process becomes error-prone
Solution Approach 1:
The system implements feedback mechanisms where the processing system continuously receives coordinate data from pucks, compares digital twin positions with physical reference points, and automatically adjusts transformations. This closed-loop feedback process ensures consistent and reliable calibration by continuously monitoring and correcting alignment accuracy.
Solution Approach 2:
The patent replaces error-prone manual measurement and adjustment processes with automated computational algorithms that process coordinate data and calculate precise transformations. This substitution eliminates human error in calibration procedures while maintaining high measurement precision through systematic computational processing.
3Productivity
If automated calibration systems with multiple pucks are deployed, then calibration speed and accuracy improve, but device complexity increases
Solution Approach 1:
The pucks serve multiple functions: they act as reference markers for location identification, provide coordinate data for calibration calculations, and enable both translation and rotation transformations of the digital twin. This multi-functionality reduces the need for separate calibration devices while maintaining high calibration speed and accuracy.
Solution Approach 2:
The pucks act as intermediary elements between the physical environment and the digital twin calibration system. Instead of directly measuring complex spatial relationships, the system uses simple coordinate data from pucks as intermediaries to calculate the necessary transformations, simplifying the overall calibration process despite using multiple devices.

AI summary
A system for calibrating a digital twin includes first and second pucks and a computing device. The first puck is configured to be disposed at a first location and to emit a first signal indicative of a first set of coordinates of the first location. The second puck is configured to be disposed at a second location and to emit a second signal indicative of a second set of coordinates of the second location. The computing device is configured to receive the first set of coordinates of the first location, receive the second set of coordinates of the second location, align a first reference point of the digital twin with the first set of coordinates of the first location, and align a second reference point of the digital twin with the second set of coordinates of the second location.
