Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screw-based fastening means are used to mount geodetic devices, then mechanical stability is improved, but ease of operation deteriorates and time consumption increases
Solution Approach 1:
The patent replaces the traditional screw-based mechanical fastening system with a magnetic attachment system. The magnetic units provide sufficient holding force to maintain mechanical stability while allowing for tool-free, rapid attachment and detachment of geodetic devices, thereby improving ease of operation without sacrificing strength
Solution Approach 2:
The patent changes the fundamental attachment parameter from friction-based screw fastening to magnetic field-based attraction. By utilizing magnetic force as the primary attachment mechanism, the system achieves both strong holding capability and easy operation through simple rotational movement to engage or disengage the magnetic units
2Ease of operation
If magnetic units are used for attaching geodetic devices, then ease of operation is improved, but mechanical stability may deteriorate
Solution Approach 1:
The magnetic attachment system is divided into separate magnetic units that can be independently positioned and engaged. This segmentation allows for distributed magnetic force application across multiple contact points, enhancing overall mechanical stability while maintaining the ease of operation characteristic of magnetic attachment
Solution Approach 2:
The patent combines multiple magnetic units into a unified attachment system that integrates both the ease of magnetic attachment and the stability of multi-point contact. The circular arrangement with alternating polarities merges the magnetic attraction forces to create a stable, multi-directional holding mechanism
3Adaptability or versatility
If magnetic units with alternating polarities are used, then adaptability is improved, but device complexity increases
Solution Approach 1:
The magnetic units with alternating polarities in circular arrangement serve multiple functions: they provide attachment force, enable rotational engagement for easy operation, and create stable multi-point contact. This multi-functionality achieves adaptability without proportionally increasing complexity, as the same structural features serve multiple purposes

AI summary
Embodiments provide for a geodetic assembly (200) for land surveying. The geodetic assembly (200) may include a first element (210) including a first magnetic unit (270) and a second element (250) including a second magnetic unit (260). The second element may be part of a support structure (240) of the geodetic assembly and is adapted to mate with the first element for supporting a geodetic device (230), the first element being attached to the geodetic device (or vice versa). The second magnetic unit is arranged to interact with the first magnetic unit for locking or unlocking the first element on the support structure. Each of the first magnetic unit and the second magnetic unit is divided in a plurality of regions (320a-d, 360a-d) arranged in a circular manner such that two adjacent regions have magnetic poles of opposite polarities. The geodetic assembly may further comprise at least one magnetic shield (270) for shielding the geodetic device, or a magnetically sensitive device (280) arranged at the support structure, from the first magnetic unit and the second magnetic unit.
