Engineering Contradiction Analysis
1Productivity
If manual handling with forklift is used for battery swapping, then the system is simple and easy to operate, but the swapping process is time-consuming and labor-intensive with low efficiency
Solution Approach 1:
The system uses self-service principles by enabling the battery swapping process to be automatically controlled without continuous human intervention. The control device coordinates the hoister and end effector to autonomously complete the swapping operations, reducing manual labor while maintaining operational simplicity.
Solution Approach 2:
The patent replaces the traditional mechanical forklift-based manual handling system with an automated hoister and end effector system. This substitution introduces mechanical automation components that can precisely grip, lift, and position batteries, significantly improving swapping efficiency while managing complexity through integrated control.
2Measurement precision
If GPS or image technology is used for positioning in complex environments, then the system provides automated positioning capability, but the positioning accuracy is insufficient due to signal interference and low visibility
Solution Approach 1:
The positioning line serves as an intermediary element between the battery-to-be-swapped vehicle and the battery swapping van. It provides a direct physical reference that enables accurate relative positioning without relying on GPS signals or image processing, effectively bypassing the harmful effects of signal interference and low visibility in complex mining environments.
3Productivity
If automatic transit and mounting device is used for battery swapping, then the swapping process is more efficient, but the device cannot accurately determine the mounting location due to positioning limitations
Solution Approach 1:
The positioning line acts as a mediator that enables the automatic transit and mounting device to accurately determine the mounting location. By providing a direct physical reference between the vehicle and van, the positioning line allows the automated system to precisely locate and mount the battery without the positioning errors that would otherwise limit automated operation.
Solution Approach 2:
The system replaces unreliable electronic positioning methods with a mechanical positioning line reference system. This mechanical approach provides tangible, accurate spatial reference that enables the automated hoister and end effector to precisely execute mounting operations, combining automation with mechanical precision.

AI summary
This application relates to a vehicle battery swapping method. The method includes: connecting a positioning line of a battery swapping van to a predetermined reference point of a battery-to-be-swapped vehicle; obtaining a distance between a coordinate origin of a hoister of the battery swapping van and the reference point of the battery-to-be-swapped vehicle, and angles of the positioning line with respect to a travel direction, a longitudinal direction, and a vertical direction, respectively, of the battery-to-be-swapped vehicle; and determining, based on the obtained distance and angles, a moving track of an end effector of the hoister. This application further relates to a battery swapping van configured to swap a vehicle battery, an electronic device, and a computer-readable storage medium.
