Engineering Contradiction Analysis
1Measurement precision
If traditional methods are used to generate and control three-dimensional cue paths, then precise spatial and temporal coordinates can be achieved, but the process becomes complex and time-consuming
Solution Approach 1:
The system creates a virtual copy of the physical stage environment in a computer-generated three-dimensional model. Users can manipulate cue paths in this virtual model, and the system automatically translates these manipulations into precise control signals for physical actuators. This copying approach maintains measurement precision while simplifying the control process by allowing intuitive visual manipulation rather than complex coordinate programming.
Solution Approach 2:
The system introduces a computer-generated three-dimensional model as an intermediary between the user's intuitive spatial understanding and the precise control requirements of physical actuators. This intermediary layer automatically handles the complex coordinate transformations and control signal generation, reducing the complexity of direct path control while maintaining precision through automated calculations.
2Measurement precision
If traditional methods are used to generate and control three-dimensional cue paths, then precise spatial and temporal coordinates can be achieved, but the process becomes time-consuming
Solution Approach 1:
By working with a virtual copy of the stage environment, users can quickly visualize and manipulate cue paths without repeatedly calculating and programming precise coordinates. The system automatically processes these manipulations in real-time, significantly reducing the time required for path generation and adjustment while maintaining coordinate precision through automated computational geometry.
Solution Approach 2:
The system performs preliminary calculations and preparations by maintaining a pre-rendered three-dimensional model of the stage environment with all spatial relationships pre-computed. When users manipulate cue paths, the system leverages this pre-prepared model to quickly generate control signals without performing complex real-time calculations, thereby reducing processing time while preserving precision.
3Ease of operation
If intuitive input methods are used for path design, then ease of operation improves, but manufacturing precision may be compromised
Solution Approach 1:
The system allows users to design paths through intuitive manipulation of objects in a virtual three-dimensional model, then automatically translates these intuitive inputs into precise control signals. The virtual model acts as a buffer that captures intuitive user intentions while the system's automated coordinate extraction and signal generation processes ensure manufacturing precision is maintained in the physical execution.
Solution Approach 2:
The computer-generated three-dimensional model serves as an intermediary that bridges intuitive user interaction and precise control execution. Users interact with the virtual model using natural, intuitive gestures and manipulations, while the system automatically performs the precise coordinate calculations and control signal generation, ensuring that ease of operation does not compromise path execution accuracy.
