Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If hydraulic systems use components from different manufacturers or types, then system flexibility and component versatility improve, but machine controller reprogramming is required which reduces operational efficiency
Solution Approach 1:
The patent introduces a hydraulic control system as an intermediary between the machine control system and diverse hydraulic outputs. This intermediary handles the complexity of different hydraulic component protocols and interfaces, translating machine control system commands into appropriate control signals for various hydraulic outputs without requiring reprogramming of the machine control system itself.
Solution Approach 2:
The hydraulic control system is designed with universal functionality to support multiple types of hydraulic outputs from different manufacturers. It can adapt to different hydraulic component protocols and interfaces through a standardized communication interface, allowing the same control system to work with various hydraulic cylinders, motors, and other actuators without reconfiguration.
2Measurement precision
If machine control systems need to know exact hydraulic system construction details, then control precision improves, but system complexity and programming requirements increase
Solution Approach 1:
The patent extracts the complexity of hydraulic system construction details from the machine control system and concentrates it in the hydraulic control system. The machine control system only needs to send generic control commands, while the hydraulic control system handles the detailed interpretation and execution specific to each hydraulic output type, thereby reducing machine control system complexity while maintaining control precision.
Solution Approach 2:
The hydraulic control system acts as an intermediary that shields the machine control system from complexity. It receives simple commands from the machine control system and automatically determines the appropriate control parameters and signals based on the specific hydraulic output configuration, maintaining control precision without exposing machine control system complexity.
3Device complexity
If hydraulic outputs are controlled separately by machine control system, then system architecture simplicity improves, but control efficiency and responsiveness deteriorate
Solution Approach 1:
The patent segments the control function into two parts: the machine control system that sends high-level commands and the hydraulic control system that executes detailed control. This segmentation allows the hydraulic control system to specialize in efficient hydraulic control operations while the machine control system maintains overall system coordination, improving control efficiency without overly complicating the overall architecture.
Solution Approach 2:
The patent adds a new control dimension by introducing the hydraulic control system as an intermediate layer. This creates a hierarchical control structure where machine control system commands are translated into detailed hydraulic control signals, enabling more responsive and efficient hydraulic control while keeping the machine control system architecture relatively simple.
