The angle origin of the laser scanner is made adjustable, allowing users to define the angular reference explicitly or implicitly through optical markers, eliminating the need for factory-set references and enabling flexible assembly and evaluation without coordinate transformations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a factory-fixed angle reference is used in laser scanners, then the device structure is simplified and manufacturing is easier, but the adaptability to different applications is reduced and complex coordinate transformations are required
Solution Approach 1:
The patent implements a dynamic angle reference system where the reference angle can be adjusted and redefined during operation. The evaluation unit allows the angle origin to be shifted to different angular positions within the angular range, enabling the laser scanner to adapt to different application requirements without physical reconfiguration or complex coordinate transformations.
2Device complexity
If a factory-fixed angle reference is used, then device complexity is reduced, but the complexity of data handling and coordinate transformations increases
Solution Approach 1:
The patent changes the parameter of the angle reference from a fixed factory-set value to an adjustable parameter that can be modified by the evaluation unit. This allows the angle origin to be dynamically repositioned, simplifying data handling and eliminating the need for complex coordinate transformations while maintaining low device complexity.
3Adaptability or versatility
If the angle origin is made adjustable, then adaptability and flexibility are improved, but device complexity and computational requirements increase
Solution Approach 1:
The evaluation unit is designed to perform multiple functions: it processes measurement data from the laser scanner and simultaneously manages the angle reference adjustment. This multi-functionality allows the system to achieve high adaptability without adding separate dedicated components, thereby minimizing the increase in device complexity.
