Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a TOF scanner is moved to different locations to obtain complete scans, then the completeness of the scan improves, but the time required to scan the environment increases
Solution Approach 1:
The patent applies the Dynamics principle by enabling the scanner to perform measurements while in motion rather than requiring it to be stationary at multiple locations. The mobile scanning system captures 3D coordinate data continuously as it moves through the environment, eliminating the need to stop at multiple scan positions and significantly reducing the total scanning time while maintaining complete coverage of the scanned area.
2Productivity
If measurement systems are mounted to movable structures like carts, then the scanning speed improves, but the data quality decreases
Solution Approach 1:
The patent applies the Intermediary principle by introducing a specialized mobile platform that serves as an intermediary between stationary high-precision scanners and moving inspection needs. This platform integrates the scanner with motion compensation mechanisms and stabilization systems, allowing the scanner to move while maintaining measurement precision comparable to stationary systems.
3Measurement precision
If the cart is stopped at scan locations to perform measurements, then the measurement precision improves, but the total scanning time increases
Solution Approach 1:
The patent applies the Continuity of useful action principle by enabling continuous scanning measurements to be performed while the platform is in motion, rather than requiring intermittent stops at scan locations. The system maintains continuous data acquisition throughout the entire scanning process, eliminating idle time between measurements and significantly reducing the total time required to complete the scan while maintaining measurement precision through motion compensation.

Function Achieved in This Case
Enables faster and more efficient scanning of environments with improved data quality by allowing simultaneous 3D scanning and map generation during movement, reducing the need for multiple stationary scans.
Implementation Method 1
A TOF laser scanner is a scanner in which the distance to a target point is determined based on the speed of light in air between the scanner and a target point
Implementation Method 2
the second scanner having a rotary mirror arranged to reflect an emitted second beam of light and a second reflected light

AI summary
A system and method for measuring three-dimensional (3D) coordinate values of an environment is provided. The system includes a movable base unit a first scanner and a second scanner. One or more processors performing a method that includes causing the first scanner to determine first plurality of coordinate values in a first frame of reference based at least in part on a measurement by at least one sensor. The second scanner determines a second plurality of 3D coordinate values in a second frame of reference as the base unit is moved from a first position to a second position. The determining of the first coordinate values and the second plurality of 3D coordinate values being performed simultaneously. The second plurality of 3D coordinate values are registered in a common frame of reference based on the first plurality of coordinate values.
