Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the blinking period is set to a constant time, then the blinking frequency should be stable, but the actual blinking period fluctuates due to processing load variations
Solution Approach 1:
The patent implements feedback by measuring the actual update time of the display unit and using this measured value to adjust the blinking control parameters. The control unit determines on-time and off-time based on the measured update time, creating a closed-loop system that compensates for processing load variations and maintains stable blinking frequency.
Solution Approach 2:
The patent changes the parameters of the blinking control (on-time and off-time) based on the measured update time. By adjusting these parameters dynamically according to the actual display update performance, the system maintains consistent blinking frequency despite variations in processing load.
2Stability of the object's composition
If the image is updated at a constant period, then the display timing should be regular, but the actual update time fluctuates due to processing load
Solution Approach 1:
The patent measures the actual update time of the display unit and uses this feedback information to adjust subsequent blinking control parameters. This allows the system to maintain regular update timing perception for the user while accommodating variations in processing load.
Solution Approach 2:
The patent makes the blinking control parameters dynamic by adjusting them based on the measured update time. Instead of using fixed constant values, the system adapts the on-time and off-time parameters to match the actual display performance, maintaining stability while allowing processing flexibility.
3Ease of operation
If the blinking control uses fixed time values, then the control logic is simple, but the blinking frequency fluctuates and causes viewer discomfort
Solution Approach 1:
The patent introduces feedback by measuring the actual update time and using this measured value to determine the blinking parameters. This maintains relatively simple control logic while significantly improving blinking frequency consistency, as the control adapts to actual system performance rather than relying on fixed theoretical values.
Solution Approach 2:
The system performs self-adjustment by automatically measuring its own update time and using this information to optimize its blinking control parameters. This self-service approach maintains simplicity while improving reliability, as the system adapts to its own actual performance characteristics.

AI summary
A display control device includes an image creating unit, a display output unit, an update time measuring unit, and a blinking control unit. The blinking control unit determines a bright time and a dark time to be integral multiples of an update time so that a blinking frequency is within a tolerance frequency range. In a blinking control, the blinking control unit executes an on-display control to instruct the image creating unit to create a bright image for a number of times of a value obtained by dividing the bright time by the update time, and then executes an off-display control to instruct the image creating unit to create the dark image for a number of times of a value obtained by dividing the dark time by the update time, and repeats the on-display control and the off-display control until the blinking control ends.
