Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the time code signal and audio signal are transmitted using the same transmission line, then the device complexity is reduced and user efficiency is improved, but the time code signal and audio signal interfere with each other and cannot be accurately distinguished
Solution Approach 1:
The patent segments the signal transmission path by providing separate transmission lines for time code signals and audio signals. The time code signal is transmitted through a first transmission line while the audio signal is transmitted through a second transmission line, preventing mutual interference between the two signal types and ensuring accurate signal distinction.
2Ease of operation
If the time code signal value is fixed during transmission, then the transmission is simple, but the time code signal cannot be accurately distinguished from the audio signal resulting in mutual interference
Solution Approach 1:
The patent applies local quality by differentiating the transmission characteristics of time code signals and audio signals through separate transmission lines. This allows each signal type to maintain its specific characteristics without interference, enabling accurate distinction while keeping the transmission system operationally simple.
3Reliability
If separate transmission lines are used for time code and audio signals, then the signal distinction accuracy is improved, but the device complexity increases
Solution Approach 1:
The patent implements multi-functionality by designing a transmission system where the same device can handle both time code signals and audio signals through separate transmission lines. The time code signal transmission path and audio signal transmission path are independently designed but integrated into a unified device, allowing the device to perform multiple functions without significantly increasing overall complexity.

AI summary
A time code generation circuit includes: a port; a time code switching module connected to the port; an amplitude adjustment module connected to the time code switching module; and a main control module respectively connected to the time code switching module and the amplitude adjustment module. The amplitude adjustment module is configured to receive a time code signal generated by the main control module and perform amplitude adjustment to generate time code signals with different amplitudes. The time code switching module is configured to receive a time code signal undergone amplitude adjustment. The main control module is configured to receive first operation input to generate a time code signal and configure the time code signal to be input into the amplitude adjustment module for amplitude adjustment. The time code signal undergone amplitude adjustment is transmitted into the port through the time code switching module.
