Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If display devices are manufactured using standard manufacturing processes, then production cost and time are reduced, but variations in display appearance and performance occur due to manufacturing tolerances and material differences
Solution Approach 1:
The system performs preliminary detection of display characteristics during device initialization or factory testing, measuring parameters such as brightness, contrast, and color temperature. Based on these measurements, compensation values are pre-calculated and stored in a lookup table, enabling automatic compensation before the device is used by the patient.
Solution Approach 2:
The system dynamically adjusts display parameters (brightness, contrast, gamma correction, color temperature) based on detected display characteristics and ambient lighting conditions. By changing these parameters in real-time, the system compensates for manufacturing variations and ensures consistent visual appearance across different devices and viewing conditions.
2Device complexity
If display parameters are fixed during manufacturing, then device complexity is reduced, but the ability to compensate for manufacturing variations and ensure consistent appearance is lost
Solution Approach 1:
The display system performs self-diagnosis and self-adjustment by automatically detecting its own characteristics and compensating for deviations. The microcontroller measures display parameters, compares them against target values, and adjusts control signals accordingly, eliminating the need for manual calibration or complex hardware modifications.
Solution Approach 2:
The system implements a closed-loop feedback mechanism where display output is continuously monitored, and adjustment signals are generated based on the difference between actual and desired display characteristics. This feedback loop ensures that manufacturing variations are automatically compensated, maintaining consistent appearance without increasing overall system complexity.
3Manufacturing precision
If manual calibration of each display device is performed, then display appearance consistency is improved, but time consumption and labor costs increase significantly
Solution Approach 1:
The system replaces manual mechanical calibration processes with automated electronic detection and adjustment. Instead of requiring technicians to physically adjust display components, the system uses software-based parameter measurement and control, dramatically reducing calibration time while maintaining or improving precision.
Solution Approach 2:
The system performs automatic calibration during device initialization or factory testing, measuring display characteristics and storing compensation values before the device is used. This preliminary automated calibration eliminates the need for time-consuming manual adjustment during setup or manufacturing, reducing both time loss and labor costs.
