Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate position information acquisition units are used with wireless communication, then position and attitude information can be acquired, but device complexity increases and measurement errors occur due to correction between devices
Solution Approach 1:
The patent combines the collimation distance measuring unit and scanner unit into a single integrated device mounted on the mobile body. The collimation distance measuring unit measures distance to a measurement target while the scanner unit measures distance to the measurement target object, and both units share a common coordinate system origin, eliminating the need for wireless communication and correction between separate devices.
2Measurement precision
If separate position information acquisition units are used with wireless communication, then position and attitude information can be acquired, but setting becomes complicated
Solution Approach 1:
The patent integrates the collimation distance measuring unit and scanner unit with shared mounting and coordinate system, eliminating the need for complex wireless communication setup and correction procedures. The integrated design allows for simpler operation and setup while maintaining accurate attitude information measurement.
3Measurement precision
If GPS is used for distance and angle measurement, then position information can be acquired, but it cannot be used in places where radio waves cannot reach
Solution Approach 1:
The patent replaces GPS (radio wave-based) with a laser-based measurement system using the collimation distance measuring unit and scanner unit. This optical system does not rely on radio waves and can function in environments such as tunnels where GPS signals are unavailable, significantly improving environmental adaptability while maintaining measurement precision.

Implementation Method 1
measure a distance to the measurement target based on a first reflected distance measuring light resulting from the first distance measuring light being reflected by the measurement target and a first internal reference light
Implementation Method 2
measure a distance to the measurement target object based on a second reflected distance measuring light resulting from the second distance measuring light being reflected by the measurement target object and a second internal reference light
Implementation Method 3
a telescope section configured to collimate the measurement target and radiate the first distance measuring light
