Engineering Contradiction Analysis
1Productivity
If manual input method is used for entering user information, then the system is simple to operate, but the data input efficiency is low and error rate is high
Solution Approach 1:
The patent replaces the mechanical manual input system with an optical signal recognition system. The signal identifying device captures optical signals (such as from a display screen) and automatically converts them into digital data, eliminating the need for manual keyboard input. This substitution dramatically improves data input efficiency while reducing human error.
Solution Approach 2:
The patent uses optical copying technology where the signal identifying device captures visual information from a display and converts it into digital form. By copying the displayed information optically and converting it to bit information, the system achieves rapid, accurate data input without manual intervention.
2Reliability
If manual input method is used for entering user information, then the device structure is simple, but the correction rate of OTP is low
Solution Approach 1:
The patent replaces error-prone manual input with automated optical recognition, significantly improving OTP correction rate. The signal identifying device automatically captures, processes, and validates data, eliminating human errors in data entry and thereby enhancing the reliability of OTP generation.
Solution Approach 2:
The patent implements a feedback mechanism where the signal identifying device continuously monitors and validates the captured optical signals. The system compares the received data with expected formats and provides automatic correction or rejection of erroneous data, thereby improving OTP accuracy and reliability.
3Productivity
If optical signal conversion method is used, then data transfer efficiency is improved, but the device complexity increases
Solution Approach 1:
The patent replaces manual data entry mechanisms with an optical signal conversion system.
