Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional transmission line installation methods are used without real-time data communication and synchronization, then the device complexity is reduced, but the installation accuracy and reliability deteriorate due to inability to adapt to unknown duct geometry
Solution Approach 1:
The installation system is divided into multiple independent components (control unit, conveying apparatus, local controllers) that can function semi-autonomously but synchronize through data communication. This segmentation allows each component to be optimized independently while maintaining overall system reliability through coordinated operation.
Solution Approach 2:
Local controllers continuously monitor installation parameters and communicate status information to the control unit, which adjusts conveying apparatus operation in real-time. This feedback loop enables the system to adapt to unknown duct geometry and maintain high installation success rates.
2Reliability
If manual installation methods are used to divide the run into shorter distances, then the reliability of reaching full distance is improved, but the productivity and time consumption worsen due to increased manual labor and multiple splices
Solution Approach 1:
The system replaces manual mechanical installation processes with an automated conveying apparatus that uses data communication and synchronized control to push transmission lines through ducts. This substitution eliminates the need for manual labor, multiple splices, and divided runs, simultaneously improving both reliability and productivity.
Solution Approach 2:
The control unit dynamically adjusts conveying apparatus parameters (speed, force, direction) based on real-time status information from local controllers. This parameter optimization allows the system to maintain high installation speeds while ensuring complete and reliable full-distance installation.
3Measurement precision
If installation equipment operates without real-time status monitoring and adjustment, then the device complexity is reduced, but the measurement precision and control accuracy deteriorate due to inability to detect transmission line position
Solution Approach 1:
Local controllers are designed to perform multiple functions: monitoring transmission line position, detecting status information, communicating with the control unit, and adjusting conveying parameters. This multi-functionality achieves high measurement precision without proportionally increasing overall system complexity.
