Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a gas turbine system is designed for fixed power generation, then reliability is improved, but adaptability deteriorates
Solution Approach 1:
The gas turbine system is designed to perform multiple functions by switching between driving hydraulic pumps for mechanical power and driving generators for electrical power. The power transmission device can be reconfigured to connect the gas turbine to either hydraulic pumps or generators, enabling the same prime mover to serve different power needs at oil well sites.
2Reliability
If a power generation system is designed for fixed installation, then reliability is improved, but mobility deteriorates
Solution Approach 1:
The power generation system is divided into separable modules: the gas turbine unit, hydraulic pumps, and generators can be independently positioned and connected. The power transmission device uses detachable couplings that allow the system to be assembled, disassembled, and relocated between different oil well sites while maintaining operational reliability through standardized connection interfaces.
3Reliability
If a power transmission device is permanently coupled, then reliability is improved, but adaptability deteriorates
Solution Approach 1:
The power transmission device incorporates detachable couplings and switching mechanisms that allow dynamic reconfiguration of the power transmission path. The system can switch between different load configurations (hydraulic pumps or generators) by engaging or disengaging coupling devices, providing both operational reliability during power transmission and adaptability for different working conditions.
