Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual measurement tools are used to map venue dimensions, then measurement accuracy can be achieved, but the process becomes extremely time-consuming and labor-intensive
Solution Approach 1:
The patent replaces manual mechanical measurement tools (tapes, rulers) with an automated aerial vehicle system equipped with sensors and cameras. The vehicle autonomously navigates the venue and captures spatial data, eliminating the need for manual measurement while maintaining accuracy through sensor-based detection and image processing.
Solution Approach 2:
The system creates a digital 3D model (copy) of the physical venue by capturing images and sensor data from multiple angles. This digital representation contains all dimensional information needed for event planning, eliminating the need to physically measure and record every dimension manually.
2Ease of operation
If special equipment like aerial work platforms or scaffolding is used to reach high areas, then high venue features can be surveyed, but equipment complexity and safety risks increase
Solution Approach 1:
Instead of bringing measurement equipment up to high areas using complex scaffolding or aerial platforms, the patent inverts the approach by deploying a lightweight aerial vehicle that flies down to the features and captures data from above. This eliminates the need for ground-based support equipment and reduces safety risks associated with working at heights.
3Loss of information
If comprehensive venue mapping is performed manually, then complete dimension data can be collected, but the data is difficult to visualize and process
Solution Approach 1:
The system creates a visual digital 3D model that serves as a copy of the physical venue. This model automatically integrates all captured images and sensor data into an interactive visualization that is easy to navigate and analyze, eliminating the need to manually process and visualize raw measurement data.
Solution Approach 2:
The patent introduces software processing as an intermediary between data collection and data utilization. The software automatically processes raw sensor data and images, generates the 3D model, and provides interactive visualization tools, making the complete venue data easily accessible and actionable without manual intervention.

Data Source
AI summary
A method of surveying a venue includes scanning at least a portion of the venue using an unmanned aerial vehicle having at least one scanner, converting scan data gathered by the at least one scanner into three-dimensional location data, displaying the three-dimensional location data as a three-dimensional model, analyzing the three-dimensional model, and designating portions of the three-dimensional model with semantic mapping.
