Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional Morse code signal lamps are used, then the system is simple and reliable, but the transmission speed is slow and requires skilled operators
Solution Approach 1:
The patent replaces the manual mechanical operation of traditional signal lamps with an automated computer-controlled shutter system. The computer receives information, processes it, and automatically controls the shutter to modulate the light source, eliminating the need for manual Morse code operation and significantly increasing transmission speed while reducing the skill requirement for operators
Solution Approach 2:
The system incorporates automatic message preparation and transmission capabilities where the computer handles the entire communication process autonomously. The computer can store, retrieve, and transmit messages without human intervention beyond initial input, making the system self-sufficient and dramatically improving productivity
2Measurement precision
If manual operation is used, then the device is simple to operate, but accuracy is prone to errors
Solution Approach 1:
The patent eliminates manual operation errors by replacing human operators with an automated computer控制系统. The computer precisely controls the shutter timing and light modulation according to programmed parameters, ensuring consistent and accurate transmission without the variability and errors inherent in manual Morse code operation
Solution Approach 2:
The system incorporates feedback mechanisms where the computer monitors and tracks the light signal transmission in real-time. This allows for verification of accurate transmission and potential correction of any deviations, ensuring high precision without requiring skilled operators to manually verify each signal
3Adaptability or versatility
If traditional signal lamps are used, then the system is simple and low-tech, but it cannot operate simultaneously for sending and receiving messages
Solution Approach 1:
The patent makes the system multi-functional by enabling simultaneous sending and receiving of messages through the computer-controlled architecture. The computer can manage multiple communication functions concurrently, allowing the system to operate as both transmitter and receiver at the same time, greatly enhancing its adaptability and versatility
Solution Approach 2:
The automated computer system replaces the limitations of manual operation, enabling sophisticated simultaneous transmit and receive capabilities that would be impossible with traditional signal lamps. The computer manages the timing, coordination, and processing of dual-directional communication automatically
