Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional power distribution systems are used in fracturing operations, then reliable power supply is achieved, but cable usage increases and flexibility decreases
Solution Approach 1:
The system segments power distribution into modular circuit breaker units that can be independently connected and disconnected. Each circuit breaker serves as an independent power distribution node, eliminating the need for extensive cable networks while maintaining reliable power supply to multiple fracturing equipment units.
Solution Approach 2:
The circuit breakers are designed to be dynamically connectable and disconnectable from power sources and equipment. This dynamic configuration allows the system to adapt to different operational requirements and equipment arrangements without requiring permanent cable installations, thereby increasing flexibility while reducing cable usage.
2Reliability
If multiple cables are used for power distribution, then power reliability is improved, but system complexity and safety risks increase
Solution Approach 1:
The patent extracts the power distribution function from complex cable networks and consolidates it into standardized circuit breaker units. Each circuit breaker independently provides reliable power connection, eliminating the need for multiple interwoven cables and reducing overall system complexity while maintaining power reliability.
Solution Approach 2:
The system changes the fundamental parameter of power distribution from cable-based continuous connection to circuit breaker-based modular connection. This parameter change simplifies the system architecture while maintaining reliability through standardized, easily replaceable connection units with defined electrical parameters.
3Productivity
If extensive equipment and power distribution systems are deployed, then fracturing operation capability is enhanced, but on-site footprint increases
Solution Approach 1:
The system merges power distribution functionality directly into the circuit breaker units that are already positioned near fracturing equipment. By combining power distribution and equipment control functions at the same location, the system eliminates the need for separate power distribution infrastructure, thereby enhancing operational capability while minimizing on-site footprint.
