Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If contactless dimensioning systems use sensor-based measurement, then measurement capability is provided, but sensor limitations cause opaque performance issues leading to user confusion
Solution Approach 1:
The system provides real-time feedback to users through an augmented reality display, showing visual indicators about detection quality, ground plane detection status, and measurement confidence levels. This feedback loop makes sensor performance transparent and helps users understand why certain measurements may be inaccurate, resolving the contradiction between maintaining measurement precision and improving ease of operation.
Solution Approach 2:
The patent introduces an intermediary layer between the sensor and the user - a processing system that translates complex sensor data and limitations into comprehensible visual feedback. This intermediary processes raw sensor information and presents it in user-friendly formats, bridging the gap between technical measurement capabilities and user understanding.
2Measurement precision
If users manually adjust scanning processes to improve performance, then measurement quality may improve, but time consumption increases
Solution Approach 1:
The system performs self-adjustment by automatically detecting optimal scanning parameters, object boundaries, and measurement angles. The processing system autonomously compensates for sensor limitations and adjusts scanning processes without requiring manual user intervention, thereby maintaining high measurement precision while minimizing time loss.
Solution Approach 2:
Real-time feedback provides users with immediate information about measurement quality and detection confidence, enabling quick corrective actions if needed. This reduces the time users spend making trial-and-adjustment maneuvers while maintaining measurement accuracy.
3Ease of operation
If the system provides detailed feedback about sensor performance and detection quality, then user understanding improves, but system complexity increases
Solution Approach 1:
The patent employs an intermediary processing system that sits between the complex sensor array and the user interface. This intermediary handles the complexity of sensor performance analysis, detection quality assessment, and ground plane detection algorithms, while presenting simplified, user-friendly feedback. The intermediary absorbs system complexity while maintaining ease of operation for the end user.

AI summary
A system includes: a depth reconstruction system; a display device; a processor; and memory storing instructions that when executed by the processor, cause the processor to: control the depth reconstruction system to capture a three-dimensional representation of a scene; perform automatic object detection on the three-dimensional representation of the scene; detect a ground plane in the scene; render a model of the ground plane in a live view image of the scene; perform detection of problems in a framing of the scene in a field of view of the depth reconstruction system; and display, on the display device, the live view image of the scene augmented with the rendered model of the ground plane and one or more detected framing problems.
