Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual delivery method is used, then flexibility in material handling is maintained, but labor consumption increases and human errors occur
Solution Approach 1:
The system enables self-service through automated guided vehicles that autonomously navigate the production line, pick up materials from storage locations, and deliver them to required processes without human intervention. The AGVs self-manage their routes, material handling, and coordination with production schedules, eliminating manual labor while maintaining operational flexibility
Solution Approach 2:
The patent replaces manual mechanical delivery with an automated mechanical system consisting of AGVs equipped with sensors, controllers, and material handling mechanisms. These vehicles use automated navigation and control systems to substitute human operators, thereby increasing productivity while reducing labor consumption and human errors
2Reliability
If complete set of materials is delivered to entire line, then material availability is ensured, but material picking complexity increases
Solution Approach 1:
The system segments the complete material set into process-specific subsets. The logistics execution system receives material lists and automatically divides them according to which processes require which materials, assigning specific materials to specific AGVs for delivery to specific process locations. This segmentation simplifies the picking process while ensuring all required materials are available
Solution Approach 2:
The logistics execution system acts as an intermediary between material storage and production processes. It receives material delivery requests, processes the material lists, determines optimal delivery routes and assignments, and coordinates with the AGV scheduling system. This intermediary layer manages the complexity of material distribution while ensuring reliable material availability at each process point
3Measurement precision
If automated guided vehicle is used, then delivery precision is improved, but system complexity increases
Solution Approach 1:
The AGV system is designed with multi-functionality to handle various material types and delivery scenarios through a unified platform. The vehicles can adapt to different material configurations, navigate to multiple process locations, and coordinate with different production schedules. This universality reduces the need for specialized equipment for each function, managing system complexity while maintaining high delivery precision through automated control and positioning systems

AI summary
A delivery method includes: sending, by the material requisition computer, a first material requisition request to the logistics execution system in a first material requisition case; sorting, by the logistics execution system in response to the first material requisition request, materials of battery packs based on a production quantity of the battery packs in a current production cycle, determining a first sorting result, and sending the first sorting result to the enterprise resource planning system, where the first sorting result includes material-related information required by different processes in a production line; and controlling, by the enterprise resource planning system based on the material-related information required by the different processes in the production line, the target automated guided vehicle to deliver a corresponding material to a production device for a corresponding process.
