Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mobile robot is used for reality capture and surveillance, then mobility and flexibility are improved, but measurement precision deteriorates
Solution Approach 1:
The patent replaces traditional mechanical measurement systems (CMM, articulated arms) with a mobile robot platform that integrates laser scanners and cameras. The robot uses optical and electromagnetic fields for measurement instead of mechanical contact, enabling mobility while maintaining measurement capabilities through non-contact sensing technologies.
Solution Approach 2:
The patent introduces a coordinate transformation system and reference frame alignment mechanism as intermediaries between the mobile robot's sensor data and the fixed measurement coordinate system. This mediator layer enables the robot to achieve metrology-grade accuracy by mathematically transforming mobile sensor readings into a stable reference framework.
2Measurement precision
If metrology-grade measurement accuracy is achieved, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent creates a multi-functional integrated platform that combines laser scanning, imaging, navigation, and measurement capabilities in a single mobile robot system. This universal device replaces multiple separate instruments (laser scanner, camera, GPS, measurement device) with one unified system, reducing overall complexity while maintaining high measurement precision.
Solution Approach 2:
The patent merges the sensor suite, navigation system, and measurement processing into an integrated mobile platform. By combining these previously separate systems into one unified robot platform with centralized control and data fusion, the patent reduces the complexity of managing multiple independent devices while achieving metrology-grade measurements.
3Adaptability or versatility
If a mobile robot structure with moveable parts is used, then adaptability is improved, but measurement stability deteriorates
Solution Approach 1:
The patent replaces mechanical linkages and physical connections with optical and electromagnetic sensing systems. The mobile robot uses laser ranges and camera images to measure environmental features without mechanical contact, eliminating the instability introduced by moveable mechanical parts while maintaining adaptability to various measurement scenarios.
Solution Approach 2:
The patent introduces a stable virtual reference coordinate system as an intermediary between the mobile robot's changing physical position and the measurement requirements. This mathematical reference frame remains stable despite the robot's movement, providing a consistent basis for measurements while the robot adapts its position and orientation as needed.
