Solution Overview
Problem
Current signal transmission devices using optical signals face challenges in power consumption and safety, particularly when the optical fiber cable is cut or unplugged, leading to potential laser light leakage and inefficient power management, as existing safety circuits and power-saving technologies conflict in handling abnormalities and maintaining signal reception status.
Innovation Solution
A signal transmission device with a transmission unit that converts electrical signals to optical signals and control signals, featuring an electrical-optical conversion unit, a detection unit, and a control unit that shuts down optical signal output when image information is absent or the optical signal has not arrived, ensuring power savings and safety by preventing laser light leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If optical signals are used for long-distance transmission, then transmission distance is extended, but power consumption increases and safety risks arise from laser light leakage
Solution Approach 1:
The patent implements dynamic power management by continuously monitoring optical signal reception status and adjusting laser emission accordingly. The system transitions between active emission and shutdown states based on real-time reception conditions, optimizing power consumption while maintaining transmission capability when needed.
Solution Approach 2:
The patent employs feedback mechanisms where the reception unit monitors optical signal arrival and sends status information back to the transmission unit. This closed-loop feedback enables the system to automatically adjust laser emission based on whether the optical cable is properly connected and receiving signals, preventing energy waste and safety hazards.
2Reliability
If optical signals are continuously transmitted, then signal reception reliability is maintained, but power consumption increases
Solution Approach 1:
The patent implements periodic monitoring of optical signal reception status rather than continuous transmission. The system periodically checks whether optical signals are being properly received and adjusts laser emission in response, maintaining reliability when needed while conserving power during normal operation or cable disconnection.
Solution Approach 2:
The system performs self-monitoring and self-adjustment of laser emission based on reception status. The transmission unit automatically responds to reception conditions without external intervention, shutting down or resuming emission based on whether the optical cable is properly connected and signals are being received.
3Object-affected harmful factors
If safety circuits are added to stop laser light emission, then safety is improved, but device complexity increases
Solution Approach 1:
The patent merges the safety monitoring function with the existing optical signal reception monitoring. The same reception unit that detects signal arrival for power management purposes also serves as the safety monitoring mechanism, eliminating the need for separate safety circuits and reducing overall system complexity.
Solution Approach 2:
The reception unit performs multiple functions: it monitors optical signal arrival for power management, detects cable connection status, and provides safety monitoring to prevent laser leakage. This multi-functional approach eliminates the need for dedicated safety circuits, reducing device complexity while maintaining comprehensive safety.
4Speed
If power is continuously supplied to optical transmission unit, then transmission readiness is maintained, but unnecessary power consumption occurs
Solution Approach 1:
The system performs preliminary monitoring of optical cable connection status and signal reception conditions before activating full transmission power. By checking reception status in advance and only activating power when needed, the system maintains transmission readiness when required while avoiding unnecessary power consumption during cable disconnection or normal operation.

AI summary
A transmission unit of a signal transmission device includes: a transmission-side detection unit that detects image information from an inputted electrical signal; a receiving unit that receives, from a reception unit, a status signal representing an arrival status of an outputted optical signal; and a control unit that controls an electrical-optical conversion unit on the basis of the detection result of the transmission-side detection unit and the status signal of the receiving unit so that the output of the optical signal is shut down in at least one of a case where image information is not included in an electrical signal and a case where an optical signal has not arrived.
