Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If error information is transmitted through read-back protocol, then bit error information can be notified, but implementation complexity increases due to requiring separate read-back protocol in shipment inspection device
Solution Approach 1:
The patent combines the error information transmission function with the existing display function by converting error information into visual display patterns (lines or character strings) that are shown directly on the display screen. This eliminates the need for a separate read-back protocol implementation in the shipment inspection device, as the error information is conveyed through the normal display mechanism already present in the device.
Solution Approach 2:
The patent introduces an intermediary conversion process where error information is transformed into visual representations (display lines or character strings) that can be directly observed on the screen. This intermediary form allows error notification without requiring complex protocol implementation, as the conversion to visual form serves as the mediation between error detection and error communication.
2Ease of operation
If error information is displayed as lines, then simple information can be provided, but information completeness deteriorates as only simple information is provided
Solution Approach 1:
The patent implements a dynamic display approach where the error information representation can switch between different forms (lines or character strings) depending on the specific error condition or testing requirements. This dynamic adaptability allows the system to provide simple visual indication when appropriate while also capable of displaying detailed error information when needed, thus balancing ease of operation with information completeness.
3Loss of information
If character string is directly displayed to express accurate error information, then accurate error information can be conveyed, but design structure complexity increases in source driver or gate driver
Solution Approach 1:
The patent extracts the error information processing function from the complex driver circuitry and relocates it to the display control logic. By converting error information into displayable formats (lines or character strings) through the timing controller or control logic rather than through complex source driver or gate driver modifications, the patent achieves accurate error information display while minimizing increases in driver design structure complexity.
