Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If calibration is performed periodically or irregularly due to device aging, then display characteristics can be maintained, but calibration management becomes complex and time-consuming
Solution Approach 1:
A server is introduced as an intermediary between multiple image display devices and calibration setting values. The server centrally stores calibration setting values, receives requests from devices, and manages the calibration process remotely. This mediator approach simplifies calibration management by centralizing control and eliminating the need for direct manual intervention in each device.
Solution Approach 2:
The server is designed to handle multiple functions: storing calibration setting values for multiple devices, receiving calibration requests from various devices, selecting appropriate setting values, and managing calibration schedules. This multi-functional design consolidates what would otherwise be multiple separate calibration management processes into a single universal system.
2Ease of manufacture
If the same calibration setting values are input to multiple image display devices, then calibration process is simplified, but actual display characteristics differ due to device deterioration
Solution Approach 1:
The system dynamically adapts calibration setting values based on individual device characteristics and deterioration levels. Rather than using static identical settings for all devices, the server selects and adjusts calibration parameters according to each device's specific state, enabling precise calibration that accounts for varying degrees of aging and performance degradation.
Solution Approach 2:
Each image display device receives customized calibration setting values tailored to its specific characteristics and deterioration level. The system recognizes that different devices have different calibration requirements despite using the same overall calibration process, and adjusts settings locally for each device to achieve uniform display characteristics.
3Ease of operation
If centralized server-based calibration is implemented, then calibration management is simplified and standardized, but system complexity increases
Solution Approach 1:
The server acts as a remote intermediary that handles all calibration management tasks centrally. Devices simply send requests to the server and receive calibrated settings automatically. This mediator approach simplifies device-side operations while consolidating complexity into the server, making the overall system easier to operate from the user perspective.
Solution Approach 2:
The calibration system provides self-service functionality where devices automatically send calibration requests to the server, receive appropriate setting values without manual intervention, and apply the settings autonomously. This eliminates the need for users to manually manage calibration processes while the system handles the complexity of coordinating multiple devices and their individual requirements.
