Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional agricultural work evaluation systems are used, then general agricultural works can be evaluated, but grass mowing work cannot be appropriately evaluated
Solution Approach 1:
The evaluation system is designed with specialized evaluation criteria and data collection methods specifically tailored for grass mowing work, rather than using generic agricultural work evaluation parameters. This allows the system to accurately capture the unique characteristics and quality indicators of grass mowing operations.
Solution Approach 2:
The evaluation system divides grass mowing work into distinct evaluation dimensions including cutting quality, work efficiency, and operational规范性. Each dimension has specific measurement parameters that can be independently assessed and aggregated to provide a comprehensive evaluation.
2Device complexity
If subjective experience-based evaluation is used, then evaluation can be performed without complex systems, but evaluation objectivity and consistency deteriorate
Solution Approach 1:
The system replaces subjective human judgment with automated electronic sensors and data processing. Evaluation parameters such as cutting height, work speed, and area covered are measured objectively by sensors and calculated by the control unit, eliminating personal bias and inconsistency.
Solution Approach 2:
The system provides automated feedback through the evaluation results, comparing actual performance against standard criteria. This feedback mechanism enables consistent and repeatable evaluations across different workers and conditions, improving reliability without requiring complex manual assessment procedures.
3Measurement precision
If comprehensive data collection is implemented, then evaluation accuracy improves, but system complexity and data processing burden increase
Solution Approach 1:
The control unit serves multiple functions: it controls the mower blades, collects sensor data, calculates evaluation parameters, and outputs evaluation results. This multi-functionality reduces the need for separate dedicated components for each function, thereby reducing overall system complexity while maintaining comprehensive data collection capabilities.
