Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If staff estimates target water level and flow velocity according to water demand, then operation simplicity is maintained, but control accuracy deteriorates due to random and multi-objective water demand changes
Solution Approach 1:
The patent implements automatic feedback control by acquiring real-time water level information from monitoring stations and using it to determine gate opening degree control strategies. The system continuously adjusts gate openings based on actual water levels and flow rates, replacing manual estimation with automated feedback loops that respond to changing water demands.
Solution Approach 2:
The patent replaces manual mechanical estimation operations with automated electronic control systems. The system uses electronic sensors, data acquisition devices, and control algorithms to automatically determine and adjust gate openings, substituting human staff estimation with precise electronic measurement and control mechanisms.
2Adaptability or versatility
If multiple water diversion gates are controlled independently, then individual gate control flexibility is maintained, but system stability deteriorates due to lack of coordination
Solution Approach 1:
The patent merges the control of multiple water diversion gates into a unified linkage control system. The system determines control strategies for multiple gates simultaneously based on comprehensive water level information, coordinating their operations to work together as an integrated system rather than independent units.
Solution Approach 2:
The patent creates a universal control system that manages multiple gates with different functions (water diversion, power generation, flood control) through a single coordinated strategy. The control system adapts to various operational modes and requirements while maintaining overall system stability through unified decision-making.
