Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the data transfer speed from the image storage device to the image processing device is increased to enable timely display of large-size OSD regions on high-resolution screens, then the display timeliness is improved, but data transfer errors occur during configuration changes or screen switching
Solution Approach 1:
The patent applies dynamics by making the data transfer speed adjustable rather than fixed. The control unit dynamically changes the transfer speed between high and low based on the operational state - using high speed during normal operation and low speed during screen switching or configuration changes. This dynamic adjustment resolves the contradiction by allowing fast transfer when reliability is less critical and slow transfer when reliability is paramount.
Solution Approach 2:
The patent changes the parameter of data transfer speed based on operational conditions. During screen switching or configuration changes, the control unit lowers the transfer speed parameter to prevent data transfer errors. During normal operation, the transfer speed is maintained at a higher level for timely display. This parameter change strategy directly addresses the contradiction between speed and reliability.
2Reliability
If the data transfer speed is reduced to prevent data transfer errors during configuration changes, then data transfer accuracy is improved, but the display timeliness deteriorates for large-size OSD regions
Solution Approach 1:
The patent implements periodic action by alternating between high-speed and low-speed transfer modes based on periodic operational states. The system uses high-speed transfer during normal display periods and switches to low-speed transfer during configuration change periods or screen switching periods. This periodic alternation ensures that time loss is minimized during normal operation while accuracy is maintained during critical transition periods.
Solution Approach 2:
The dynamic adjustment of transfer speed allows the system to adapt to different operational requirements. During configuration changes, the speed is reduced to ensure accuracy, while during normal operation, the speed is increased to minimize display delay. This dynamic behavior resolves the contradiction between avoiding time loss and ensuring data accuracy.
3Productivity
If a fixed high data transfer speed is used for timely OSD display, then display timeliness is improved, but configuration changes or screen switching may cause data transfer errors
Solution Approach 1:
The system transitions from a fixed transfer speed to a dynamic transfer speed that adapts to operational conditions. The control unit monitors the operational state and adjusts the transfer speed accordingly - maintaining high speed for productivity during normal operation and reducing speed for reliability during configuration changes. This dynamic approach resolves the contradiction between productivity and reliability.
Solution Approach 2:
The patent changes the transfer speed parameter based on operational context. During configuration changes or screen switching, the parameter is adjusted to a lower value to ensure data transfer stability. During normal operation, the parameter remains at a higher value for display efficiency. This conditional parameter change resolves the contradiction between productivity and reliability.

AI summary
An information processing apparatus includes: a processor; an image processor to produce an image data for being displayed on a display; and a memory to store a screen data, the screen data being capable of being transferred from the memory to the image processor at a higher transfer rate and a lower transfer rate; wherein, when a new screen data is transferred from the memory to the image processor, the processor sets the lower transfer rate during an interval at which the image processor switches the image data from an old image data to a new image data.
