Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional positioning methods are used for battery swapping, then the device structure remains simple, but the positioning accuracy between the battery swapping device and the battery bracket is insufficient
Solution Approach 1:
The patent replaces traditional mechanical positioning methods with a vision-based positioning system. Multiple visual sensors capture images of the battery bracket, and image processing algorithms calculate precise position and attitude information, eliminating the need for complex mechanical positioning structures while achieving high positioning accuracy.
Solution Approach 2:
The patent introduces visual sensors and image processing algorithms as intermediaries between the battery swapping device and the battery bracket. These intermediaries capture visual information, process it to extract position and attitude data, and use this information to guide the positioning of the battery swapping device, achieving accurate positioning without direct mechanical contact or complex mechanical structures.
2Productivity
If manual positioning adjustment is used, then the system complexity is low, but the battery swapping efficiency is reduced due to inability to achieve quick and accurate positioning
Solution Approach 1:
The patent implements a self-service positioning system where the visual sensors automatically capture images, the image processing unit automatically calculates position and attitude information, and the battery swapping device automatically adjusts its position based on the calculated data. This automated self-positioning process eliminates manual intervention, significantly improving battery swapping efficiency while maintaining reasonable system complexity.
Solution Approach 2:
The patent establishes a feedback loop where visual sensors continuously monitor the position of the battery bracket, image processing algorithms calculate the deviation from the target position, and the battery swapping device adjusts its position based on this feedback information. This closed-loop feedback mechanism enables quick and accurate positioning, thereby improving battery swapping efficiency.
3Measurement precision
If single visual sensor is used, then the system structure is simple, but the positioning accuracy and reliability are insufficient
Solution Approach 1:
The patent divides the positioning task among multiple visual sensors positioned at different locations. Each sensor captures images from its specific viewpoint, and the image processing unit integrates this segmented visual information to calculate comprehensive position and attitude data of the battery bracket, improving positioning accuracy through multi-perspective observation.
Solution Approach 2:
The patent merges the visual information from multiple visual sensors to achieve more accurate and reliable positioning. By combining images from different viewpoints and integrating the extracted feature data, the system obtains more comprehensive position and attitude information of the battery bracket, thereby improving overall positioning accuracy and reliability.
