Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If multiple automatic devices are deployed to handle sorting and tallying operations, then the hardware capability is improved, but the cooperation efficiency deteriorates leading to increased idle time and reduced overall productivity
Solution Approach 1:
The system dynamically adjusts the sorting mode (first mode with one sorting robot, second mode with multiple sorting robots) based on real-time order parameters and cargo characteristics. This dynamic adaptation allows the automatic devices to cooperate efficiently by selecting the optimal configuration for each specific sorting scenario, thereby resolving the contradiction between having multiple automatic devices and achieving high cooperation efficiency
Solution Approach 2:
The system changes operational parameters (sorting mode selection) based on order parameters such as number of orders, cargo types, and destination requirements. By adjusting the sorting mode parameter, the system optimizes the cooperation of multiple automatic devices for different sorting scenarios, improving overall productivity while maintaining high automation
2Device complexity
If traditional fixed sorting modes are used, then the system structure is simple, but the adaptability to varying consumer demands and order scenarios deteriorates
Solution Approach 1:
The sorting system transitions from fixed modes to dynamic selection between first and second sorting modes. The server automatically selects the appropriate sorting mode based on real-time order parameters, enabling the system to adapt to varying consumer demands while maintaining a relatively simple physical structure
Solution Approach 2:
The sorting system is designed with multi-functionality by incorporating both first and second sorting modes within the same facility. The same sorting zone and automatic devices can operate in different modes depending on the sorting requirements, making the system universally applicable to various order scenarios without requiring completely separate systems
3Speed
If robot AGVs continuously move to fulfill orders, then the shipping speed is improved, but the moving distance and time consumption increase
Solution Approach 1:
The server performs preliminary calculation of the optimal sorting mode before the actual sorting operation begins. By pre-determining the best sorting approach based on order parameters, the system minimizes unnecessary AGV movements and optimizes the sequence of operations, thereby reducing time consumption while maintaining fast shipping speed
Solution Approach 2:
The system uses feedback from order parameters and sorting results to continuously optimize AGV routing and sorting mode selection. The server monitors the sorting process and adjusts the sorting mode based on real-time conditions, reducing redundant movements and improving the balance between shipping speed and time consumption
