Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a transmission line drive assembly is used to apply drive force to the transmission line, then the transmission line can be advanced through the duct, but the drive force may become variable and unstable, causing damage or inadequate installation speed
Solution Approach 1:
A load cell is integrated into the air block to monitor the drive force applied to the transmission line in real-time. The load cell provides feedback signals to a control system that adjusts the drive assembly operation to maintain stable and optimal drive force, preventing both excessive force that could damage the line and insufficient force that would reduce installation speed.
Solution Approach 2:
The patent utilizes an air block that applies pneumatic pressure to generate a component of motive force on the transmission line. This pneumatic assistance works in conjunction with the mechanical drive assembly to provide more stable and controlled advancement, reducing the variability in drive force while maintaining high installation speed.
2Force
If an air block is used to apply motive force through pressurized air, then the transmission line advancement is enhanced, but air pressure loss or leakage can occur, reducing effectiveness
Solution Approach 1:
The sealing function is extracted and implemented through a dedicated integrated seal assembly within the air block. This seal assembly specifically addresses air pressure loss by creating an airtight chamber that contains the pressurized air, ensuring that the motive force is maintained without leakage and maximizing the effectiveness of the pneumatic propulsion.
3Reliability
If multiple components are used to monitor and control drive force, then drive force stability is improved, but the device complexity increases
Solution Approach 1:
The load cell is integrated directly into the air block structure, merging the monitoring function with the existing air block component. This integration approach allows for drive force monitoring and control without adding significant structural complexity, as the load cell becomes part of the air block assembly rather than a separate external device.
