Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video footage is used to analyze lifting operations, then collision detection capability is provided, but vantage point limitations and high cost remain unresolved
Solution Approach 1:
The patent creates a 3D digital copy of the construction site environment and lifting operations using sensor data from GNSS receivers, cameras, and other sensors. This virtual 3D model allows unlimited viewing angles and replay capability without requiring multiple physical cameras from different vantage points, thereby resolving the vantage point limitation while maintaining collision detection capability
Solution Approach 2:
The patent transitions from 2D video footage to a 3D virtual representation of the construction site. This dimensional upgrade enables viewers to analyze lifting operations from any angle and perspective within the 3D space, eliminating the fixed vantage point constraints of traditional video systems
2Measurement precision
If multiple sensors and cameras are deployed for comprehensive monitoring, then collision detection accuracy is improved, but system cost and complexity increase
Solution Approach 1:
The patent integrates data from multiple sensor types (GNSS receivers, cameras, accelerometers, gyroscopes) into a unified 3D virtual model of the construction site. By merging these sensor inputs into a single cohesive system that renders a comprehensive 3D animation, the patent achieves high collision detection accuracy without requiring each sensor to operate independently, thereby reducing overall system complexity and cost
Solution Approach 2:
The 3D virtual environment serves multiple functions simultaneously: it provides collision detection, enables replay of past events from any angle, offers training capabilities, and supports operational analysis. This multi-functionality reduces the need for separate specialized systems, lowering overall system cost while maintaining high measurement precision
3Reliability
If real-time monitoring of lifting operations is implemented, then operational safety is improved, but data processing requirements and system complexity increase
Solution Approach 1:
The patent pre-processes sensor data during the lifting operation to continuously update the 3D virtual model in real-time. By maintaining an always-updated virtual representation of the site, the system prepares collision detection and replay capabilities in advance, reducing the computational burden during critical analysis moments while ensuring operational safety
Data Source
AI summary
Methods and systems are disclosed for rendering a three dimensional animation of a past event. A request is received, at a processor, for re-creation of a past event associated with a job site. Input data is accessed, at the processor, regarding the past even associated with the job site wherein the input data pertains to past movements and lifts of at least one lifting device associated with the job site. A three dimensional (3D) animation is generated, at the processor, of the past event involving the past movements of the at least one lifting device. The 3D animation is displayed, on a display, depicting the past event wherein the displaying comprises playback controls for controlling the displaying.
