Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual charging method is used, then charging can be performed when power is depleted, but charging efficiency is low and time and labor are consumed
Solution Approach 1:
The charging system automatically detects when the shuttle requires charging and performs charging operations without manual intervention. The controller monitors battery status and activates the charging mechanism when power levels are low, enabling the system to service itself and eliminate the need for manual plugging and charging cable connection.
2Extent of automation
If complex structure is used, then automatic carrying and precise action can be achieved, but the structure becomes complex and size increases
Solution Approach 1:
Multiple functions are integrated into a unified compact structure. The lifting mechanism, telescopic fork, and positioning systems are combined in a way that shares common components and control systems, reducing overall structural complexity while maintaining automatic carrying and precise positioning capabilities.
Solution Approach 2:
The telescopic fork and lifting frame are designed with nested structures where components are housed within each other when not in use. The telescopic fork segments nest within the lifting frame, and various mechanical components are arranged in nested configurations to minimize the overall footprint and structural complexity.
