Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If local access and physical viewing of surfaces is required for calibration, then calibration accuracy can be ensured, but system accessibility and remote deployment capability are limited
Solution Approach 1:
The patent uses camera images to create a digital representation (copy) of the physical environment, allowing remote calibration without physical presence. The camera captures images of display surfaces and interaction surfaces, which are then processed to determine calibration parameters, replacing the need for physical viewing and manual measurement.
Solution Approach 2:
The patent replaces mechanical/physical calibration methods with automated image processing and computational algorithms. Instead of requiring physical measurement tools and manual surface viewing, the system uses computer vision technology to automatically capture, process, and analyze images for calibration purposes.
2Adaptability or versatility
If physical presence at the target environment is required for setup, then system configuration can be performed accurately, but deployment flexibility and ubiquity are reduced
Solution Approach 1:
The system performs self-calibration by automatically processing camera images and computing calibration parameters without requiring manual intervention or physical presence. The automated image processing pipeline enables the system to configure itself remotely, reducing setup complexity and enabling flexible deployment in various environments.
3Ease of operation
If remote calibration is enabled, then system accessibility and deployment flexibility improve, but the complexity of the calibration system increases
Solution Approach 1:
The patent uses a camera as a multi-functional device that serves both as an interaction surface (for user input) and as a calibration tool (for system configuration). This universal approach allows the same hardware component to perform multiple functions, reducing the need for additional specialized equipment and managing system complexity.
