Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If operation plans are generated without considering power-feeding equipment conditions, then generation speed is fast, but working machine utilization rate decreases
Solution Approach 1:
The system performs preliminary acquisition of power-feeding equipment conditions and working location information before generating operation plans. By pre-collecting data about charger locations, battery capacities, and working conditions, the system avoids complex real-time calculations and enables efficient plan generation that considers power constraints without sacrificing productivity.
Solution Approach 2:
The operation plan generation unit automatically integrates power-feeding equipment conditions into plan creation without requiring manual intervention. The system self-adjusts routing and scheduling based on acquired power infrastructure data, eliminating the need for separate manual optimization processes while improving utilization rates.
2Productivity
If power-feeding equipment conditions are considered in operation plan generation, then working machine utilization rate improves, but information processing complexity increases
Solution Approach 1:
The system extracts power-feeding equipment conditions as separate, standardized data elements (charger locations, power capacities, availability) before integrating them into operation plan generation. This extraction approach simplifies the assessment process by isolating power-related parameters from other operational constraints, making them easier to detect and measure independently.
3Productivity
If multiple conditions are considered for operation plan generation, then operational efficiency improves, but calculation time increases
Solution Approach 1:
The system performs preliminary acquisition and preprocessing of multiple condition parameters (power-feeding equipment status, working location characteristics, machine specifications) before the actual plan generation. By preparing these data elements in advance, the system reduces calculation time during plan creation while still considering all necessary conditions for operational efficiency.
