Engineering Contradiction Analysis
1Speed
If a single EV uses high-speed cellular connection or Wi-Fi hotspot to upload data, then data transfer speed is improved, but data overload and communication bottlenecks occur at the charging area
Solution Approach 1:
The system segments the data upload task by dividing voluminous data into multiple parts and distributing them across multiple EVs in the charging area. Each EV uploads a portion of the data simultaneously, preventing data overload at any single connection point and eliminating communication bottlenecks.
Solution Approach 2:
The system merges the upload capabilities of multiple EVs by having them collectively contribute to transferring the same data set. By combining their communication resources and synchronizing uploads, the system achieves higher overall throughput while distributing the data load across multiple channels.
2Device complexity
If an EV with basic capabilities attempts to upload voluminous data independently, then communication simplicity is maintained, but data transfer completeness fails due to limited bandwidth and time constraints
Solution Approach 1:
The system transforms EVs from single-function vehicles into multi-functional units that can both consume data and contribute to data uploads. By enabling EVs with basic capabilities to participate in data transfer operations, the system leverages unused communication resources across the fleet, ensuring reliable data completion without requiring every EV to have advanced capabilities.
Solution Approach 2:
The charging area infrastructure acts as an intermediary that coordinates data distribution and upload scheduling. It manages which EVs receive data portions and which EVs upload specific segments, optimizing the use of available bandwidth and ensuring complete data transfer even when individual EVs have limited capabilities.
3Duration of action of moving object
If charging time at the area is limited, then charging efficiency is improved, but data communication completion fails due to insufficient time for voluminous data transfer
Solution Approach 1:
The system maintains continuous data upload operations throughout the entire charging duration by coordinating multiple EVs. As long as at least one EV remains connected and capable of uploading, the data transfer continues without interruption, fully utilizing the available charging time and ensuring complete data communication before vehicles depart.
