Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If battery replacement is performed using conventional sequential methods, then operational simplicity is maintained, but replacement time is excessively long
Solution Approach 1:
The battery replacement system is segmented into multiple independent functional modules: a dismounting device for removing depleted batteries, a mounting device for installing charged batteries, and multiple moving devices for battery transport. Each module operates independently but coordinates through a control system, allowing parallel execution of dismounting and mounting operations to reduce total replacement time.
Solution Approach 2:
Charged batteries are pre-positioned in the battery storage mechanism before replacement is needed. When a vehicle arrives at the replacement station, the mounted batteries are already ready for immediate installation, eliminating the need to fetch charged batteries during the replacement process. This preliminary preparation enables the mounting operation to proceed in parallel with the dismounting operation.
2Productivity
If multiple batteries are handled simultaneously, then replacement efficiency is improved, but risk of battery confusion increases
Solution Approach 1:
The control system acts as an intermediary that manages and coordinates all battery handling operations. It receives identification information from sensors (such as RFID tags or barcode scanners) on batteries and vehicles, processes this information to determine the correct matching between vehicles and batteries, and then directs the moving devices to transport the correct batteries. This centralized coordination eliminates confusion even when multiple batteries are handled simultaneously.
Solution Approach 2:
The system incorporates feedback mechanisms where sensors detect battery identification information and vehicle information, and this information is fed back to the control system. The control system uses this feedback to verify correct battery-vehicle matching, confirm successful mounting and dismounting operations, and adjust operations in real-time to prevent errors. This closed-loop control ensures high reliability in battery identification and handling.
