Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If encoders are installed in each part of the unmanned engineering machinery, then the control accuracy may be improved, but the device complexity and installation difficulty increase significantly
Solution Approach 1:
The patent extracts the encoder components from each individual part and consolidates the sensing function into a centralized control system. The master computer and slave computer receive sensing values from sensors rather than from encoders installed on each component, thereby eliminating the need for multiple encoder installations while maintaining control accuracy.
Solution Approach 2:
The control system employs a universal sensing and control architecture where the master computer and slave computer serve multiple functions: receiving sensing values from various parts, processing control instructions, and coordinating multiple execution devices. This multi-functional system replaces the need for dedicated encoders at each component.
2Measurement precision
If encoders are installed in each part of the unmanned engineering machinery, then the measurement precision may be improved, but the installation process becomes more complicated
Solution Approach 1:
The encoder installation requirement is extracted and removed from the system. Instead of installing encoders on each part, the system uses sensors that provide sensing values to the master and slave computers, significantly simplifying the installation process while preserving measurement precision.
3Measurement precision
If encoders are installed in each part of the unmanned engineering machinery, then the control accuracy may be improved, but the reliability of the system decreases
Solution Approach 1:
The patent removes the encoder components from the system architecture. By replacing encoders with a sensor-based feedback system that reports to the master and slave computers, the system eliminates potential failure points associated with multiple encoder installations, thereby improving reliability while maintaining control accuracy.
4Measurement precision
If encoders are installed in each part of the unmanned engineering machinery, then the measurement precision may be improved, but the quantity of components and system complexity increase
Solution Approach 1:
The patent merges the sensing and control functions into a unified system. Instead of having separate encoders on each component, the sensing functions are consolidated into a coordinated system where the master computer and slave computer process sensing values from various parts, reducing the total number of components while maintaining sensing precision.
