Engineering Contradiction Analysis
1Productivity
If hardware circuitry is used to select n pulse signals out of m pulse signals, then rate multiplication can be achieved, but circuit complexity increases substantially and design burden increases
Solution Approach 1:
The patent replaces complex hardware circuitry with a microprocessor-based software solution. The microprocessor executes instructions to count input pulses and generate output pulses based on programmable parameters stored in memory, substituting mechanical/electrical circuit implementation with computational logic.
Solution Approach 2:
The microprocessor provides a universal platform that can perform rate multiplication for different ratios (n/m) by simply changing stored parameters rather than redesigning hardware circuits. The same physical device handles multiple multiplication ratios through software configuration.
2Ease of manufacture
If fixed interval values are used for pulse selection, then hardware implementation is simplified, but usage flexibility is reduced
Solution Approach 1:
The patent implements dynamic adjustability by storing multiple interval values in memory that can be selected based on different usage requirements. The system transitions from static fixed intervals to dynamic programmable intervals, allowing adaptation to various applications without hardware changes.
Solution Approach 2:
The system changes the parameter of pulse intervals from fixed hardware-determined values to programmable software-controlled values. By modifying stored parameter values, the system adapts to different multiplication ratios and timing requirements.
3Productivity
If hardware circuitry is designed backwards from final waveforms, then pulse selection can be achieved, but design burden on circuit designers increases substantially
Solution Approach 1:
The patent inverts the traditional design approach by using a microprocessor to execute forward-counting logic rather than designing complex backward-derivation hardware circuits. The software approach counts pulses forward and generates outputs when counters reach target values, which is more intuitive and easier to implement.

AI summary
The present invention discloses a rate multiplication method for counting a sequence of original pulse signals and outputting a target pulse signal. In this method a comparison data and original pulse signal sequence is received. The original pulse signal sequence is counted in order to obtain a pulse count. Comparing the pulse count and the comparison data. If the pulse count is equal to the comparison data, a corresponding original pulse signal is outputted as the target pulse signal. Reset and recount the pulse count, and obtain which repeatedly. In this present invention the pulse count and the pulse interval between the target pulse signals can be determined freely according to a rate.
