Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual tuning is used for display parameters, then customization and precision can be achieved, but the complexity and time consumption increase significantly
Solution Approach 1:
The system performs automatic display parameter tuning without requiring manual intervention. The tuning module automatically adjusts display parameters based on calibration data and environmental conditions, eliminating the need for operators to manually tune each display device while maintaining high precision calibration.
Solution Approach 2:
The patent replaces manual mechanical tuning operations with an automated electronic control system. The tuning module uses software-based algorithms to calculate and apply display parameter adjustments, substituting the mechanical process of manual adjustment with an automated electronic control mechanism that reduces complexity.
2Speed
If single I2C pipeline is used for control data transmission, then system simplicity is maintained, but access time and calibration speed are insufficient
Solution Approach 1:
The system divides the single I2C pipeline into multiple parallel pipelines (first I2C pipeline and second I2C pipeline). Each pipeline can independently transmit control data to different display devices or handle different calibration tasks simultaneously, thereby increasing the overall data transmission capacity and reducing access time.
Solution Approach 2:
The patent transitions from a single-dimensional sequential pipeline structure to a multi-dimensional parallel pipeline structure. By adding the dimension of parallelism with multiple I2C pipelines operating concurrently, the system achieves faster calibration speeds while managing complexity through structured pipeline design.
3Adaptability or versatility
If displays are tuned once over a certain period, then system stability is maintained, but adaptability to atmospheric changes and continuous calibration needs are compromised
Solution Approach 1:
The system implements periodic calibration cycles where display parameters are automatically adjusted at predetermined time intervals. The calibration module schedules regular tuning operations to adapt displays to changing environmental conditions while optimizing the calibration timing to minimize disruption to display operations.
Solution Approach 2:
The system incorporates feedback mechanisms that monitor environmental conditions and display performance over time. Based on this feedback, the tuning module dynamically adjusts calibration schedules and parameters, enabling the displays to adapt to atmospheric changes while optimizing calibration timing to reduce overall calibration time loss.
