Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single pressurized fluid source is used at the initial advancement device, then the system structure is simple, but the pressure of pressurized fluid decreases along the transmission path due to leaking, causing transmission line damage
Solution Approach 1:
The system divides the pressurized fluid supply into multiple independent segments, with each advancement device having its own pressurized fluid source. This segmentation ensures that pressure is maintained locally at each device without relying on long-distance fluid transport, thereby maintaining pressure consistency while managing system complexity through modular design
Solution Approach 2:
Additional pressurized fluid sources at intermediate advancement devices act as mediators to compensate for pressure losses in upstream segments. These intermediary sources ensure that each segment of the transmission path receives adequate pressure independently, preventing the cumulative pressure loss that would occur with a single distant source
2Ease of manufacture
If pressurized fluid pressure is not maintained consistently, then the installation process is simpler without continuous pressure monitoring, but the transmission line may be damaged by stretching, coiling, or crinkling
Solution Approach 1:
Pressure sensors at each advancement device provide real-time feedback on the pressure of pressurized fluid. This feedback mechanism allows the system to automatically adjust and maintain consistent pressure levels, preventing transmission line damage while keeping the installation process straightforward through automated control rather than manual intervention
Solution Approach 2:
The system preemptively maintains adequate pressure at each advancement device before transmission line installation begins. By ensuring pressure is already optimized and stable at each location in advance, the system prevents harmful effects like stretching or crinkling without requiring complex real-time adjustments during the installation process
3Reliability
If additional pressurized fluid sources are added at each advancement device, then pressure consistency is improved, but the device complexity increases
Solution Approach 1:
The system changes the parameter of pressurized fluid supply from a single centralized source to multiple distributed sources, each operating at optimized local pressure levels. This parameter change improves pressure consistency by eliminating cumulative pressure losses, while the modular nature of adding identical standardized units keeps the increase in complexity manageable and systematic
