Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual adjustment of projector settings is performed, then display consistency can be achieved, but time consumption and operational complexity increase
Solution Approach 1:
The system performs self-calibration by automatically capturing images of calibration slides, analyzing display attributes, comparing them against reference values, and adjusting projector settings without requiring manual intervention from the presenter. This eliminates the time-consuming manual adjustment process while maintaining display consistency.
Solution Approach 2:
The system automatically modifies projector display parameters such as brightness, contrast, color balance, and geometry based on the analysis of calibration slide images. By dynamically changing these parameters through automated control, the system achieves consistent display quality across different projectors and environments without manual parameter adjustment.
2Reliability
If manual adjustment of projector settings is performed, then display consistency can be achieved, but operational ease deteriorates
Solution Approach 1:
The calibration system operates autonomously by automatically capturing calibration slide images, analyzing display attributes, determining deviations from reference values, and adjusting projector settings. This self-service mechanism eliminates the need for presenters to manually navigate complex projector settings, significantly improving operational ease while maintaining display consistency.
Solution Approach 2:
The system replaces manual mechanical adjustment of projector settings with an automated digital control system. Instead of manually rotating dials or navigating menus, the system uses software-based image analysis and automated signal transmission to adjust projector parameters, making the process simpler and more accessible to users with varying technical expertise.
3Productivity
If automated calibration is implemented, then time efficiency improves, but device complexity increases
Solution Approach 1:
The calibration system is designed to work with multiple types of projectors and display environments through a universal interface. By implementing multi-functionality that accommodates different projector models, calibration standards, and meeting formats, the system achieves broad applicability without requiring separate complex calibration procedures for each scenario, thus improving time efficiency while managing complexity.
Solution Approach 2:
The system introduces a calibration management component that acts as an intermediary between the image analysis module and the projector control system. This intermediary layer handles the complexity of communicating with different projector types and translating analysis results into appropriate adjustment commands, shielding the user from complexity while maintaining high automation and time efficiency.
4Ease of operation
If automated calibration is implemented, then operational ease improves, but device complexity increases
Solution Approach 1:
The automated calibration system performs all calibration operations autonomously without requiring user expertise in display technology or projector settings. The system self-manages the entire calibration process from image capture to setting adjustment, making it easy for any presenter to use while internally handling the complexity through automated algorithms and integrated control mechanisms.
