Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If 3D surveying data is processed using traditional centralized methods, then data quality and accuracy can be maintained, but data handling becomes time-consuming and requires advanced user skills
Solution Approach 1:
The patent divides the processing of 3D surveying data into multiple segments distributed across different processing participants (surveying device, cloud processing unit, client device). Each participant handles specific processing tasks independently, enabling parallel processing and reducing the time required for complete data handling while maintaining quality through distributed validation.
2Manufacturing precision
If complete 3D surveying data is processed to ensure high quality digital models, then manufacturing precision is improved, but device complexity and processing requirements increase
Solution Approach 1:
The patent introduces a cloud processing unit as an intermediary between the surveying device and client devices. This intermediary handles complex processing tasks centrally while allowing distributed participants to perform simpler local processing, thereby maintaining high digital model quality without requiring each device to be overly complex.
3Loss of information
If all scan data is processed and transmitted to generate comprehensive digital models, then completeness of information is improved, but data overhead and bandwidth requirements increase
Solution Approach 1:
The patent extracts and processes only the essential and relevant portions of scan data at each processing stage. The distributed processing architecture allows different participants to extract specific features and information from the raw scan data, transmitting only necessary processed results rather than complete raw datasets, thereby reducing data overhead while maintaining information completeness.
4Productivity
If real-time preview of digital models is provided during data acquisition, then productivity is improved, but computing power and energy consumption increase
Solution Approach 1:
The patent implements partial processing to generate real-time previews during data acquisition. Instead of processing complete datasets, the system performs partial processing on subsets of scan data to provide sufficient preview quality for immediate assessment. This approach enables real-time feedback while consuming acceptable battery power by avoiding exhaustive processing of all data.

AI summary
The invention relates to processing scan data (105, 105') provided by a 3D surveying device (1, 1', 1", 100) to provide a digital model of an environment, wherein the processing of the scan data (105, 105') is distributed among a group of processing participants (1, 1', 1", 100, 101, 8, 8', 8", 102, 109) by deriving a scan task to be currently executed by the 3D surveying device (1, 1', 1", 100) and deriving an associated model type of the digital model of the environment to be provided by the scan data. Minimal processing units (108) of the processing of the scan data (105, 105') are determined to provide a display of a representation of a preview of the digital model in a way that it fulfils visualization criteria (122-125) associated to the model type of the digital model. A prioritization algorithm (118) is used for dynamically distributing the processing of the scan data (105, 105') among the processing participants (1, 1', 1", 100, 101, 8, 8', 8", 102, 109), wherein the prioritization algorithm (118) provides an optimization (126) in terms of definition and distribution of the different processing assignments with a short time to provide the minimum processing units (108) as a target value and with a currently available bandwidth (119) and connection stability (119) of a data exchange between the processing participants with one another, a currently available computing power (120, 130, 131, 132) on each of the processing participants (1, 1', 1", 100, 101, 8, 8', 8", 102, 109), and remaining battery power (121, 129) on the 3D surveying device (1, 1', 1", 100) as input parameters.
