Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple rotating laser units are used to achieve position determination in uneven terrain, then measurement coverage and accuracy are improved, but device complexity and cost increase significantly
Solution Approach 1:
The patent combines multiple laser units into a single integrated base station that emits multiple beam planes simultaneously. Instead of using separate rotating laser units, the invention merges their functions into one device that can generate multiple beam planes with different orientations, thereby reducing system complexity while maintaining measurement capabilities.
Solution Approach 2:
The patent introduces a wobbling mechanism that dynamically adjusts the orientation of the beam plane normal. By making the normal vector dynamic and capable of assuming multiple orientations through controlled wobbling motion, the system achieves enhanced measurement coverage and accuracy without requiring multiple fixed laser units.
2Adaptability or versatility
If multiple rotational axes are implemented to enable flexible beam orientation, then adaptability to different terrains is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent replaces multiple fixed rotational axes with a single dynamic wobbling mechanism. The normal to the beam plane can dynamically assume multiple orientations through controlled wobbling motion, providing terrain adaptability without the mechanical complexity of multiple rotational axes.
Solution Approach 2:
The single base station with wobbling capability serves multiple functions that would otherwise require separate devices. It can adapt to different terrains and measurement requirements by adjusting the beam plane orientation dynamically, making the system universal and versatile without additional mechanical components.
3Measurement precision
If precise synchronization of multiple laser units is required, then measurement accuracy is improved, but system complexity and operational difficulty increase
Solution Approach 1:
The patent eliminates the need for synchronization between multiple laser units by merging their functions into a single base station. The wobbling mechanism inherently provides temporal coordination of multiple beam plane orientations without requiring external synchronization signals or complex timing mechanisms.
4Measurement precision
If multiple beam planes with different orientations are emitted, then vertical angle determination is improved, but optomechanical complexity increases
Solution Approach 1:
The patent uses a dynamic wobbling mechanism to generate multiple beam plane orientations from a single optical system. Instead of requiring multiple fixed optical axes, the system dynamically adjusts the beam plane orientation through controlled wobbling motion, simplifying the optomechanical design while maintaining vertical angle determination capabilities.

AI summary
A base station for measurements emits measurement radiation into a beam plane with a wobbling motion of the beam plane, such that a position of a normal of the beam plane is changed in a predefined manner such that orientations of the normal occur repeatedly, for example with a cyclic repetition of the beam plane. A measuring assembly for such a base station can be provided with at least one associated remote terminal. A method for guiding a mobile object, in particular a vehicle, uses a base station and at least one active remote terminal permanently associated therewith, which form a transceiver measuring assembly.
