Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual rough classification is used for battery sorting, then operational simplicity is maintained, but sorting accuracy deteriorates and recycling efficiency is reduced
Solution Approach 1:
The patent replaces manual mechanical classification with an automated optical detection system. A camera captures images of batteries on the conveyor belt, and image recognition algorithms automatically identify battery types, replacing human visual inspection and manual sorting operations.
Solution Approach 2:
The system enables batteries to be automatically sorted without human intervention. The conveyor belt transports batteries through the detection zone, the image recognition system processes images in real-time, and sorted batteries are automatically directed to different collection areas based on identified types.
2Difficulty of detecting and measuring
If X-ray machines are used for battery classification, then detection capability is enhanced, but cost increases and the ability to distinguish lithium battery types deteriorates
Solution Approach 1:
The patent replaces expensive X-ray machines with a more cost-effective camera-based image recognition system. The camera device captures visual information of battery exteriors, labels, and markings, providing sufficient classification capability at a fraction of the cost of X-ray equipment.
Solution Approach 2:
The system creates visual copies (images) of batteries using a camera instead of using expensive X-ray imaging. These image copies are then processed by recognition algorithms to identify battery types, achieving accurate detection without the high cost of X-ray technology.
3Device complexity
If conventional image recognition technology is used for battery sorting, then implementation cost is reduced, but sorting accuracy deteriorates to near human eye recognition levels
Solution Approach 1:
The patent employs dynamic image capture by moving the camera synchronously with the battery movement on the conveyor belt. This ensures the battery remains in the optimal capturing area during image acquisition, maintaining high image quality and recognition accuracy while keeping the system cost-effective.
Solution Approach 2:
The system performs preliminary actions by accelerating batteries to a standard speed before image capture. The acceleration device ensures batteries reach the optimal capturing area with consistent velocity, improving image quality and recognition accuracy before the actual sorting decision is made.
4Device complexity
If battery sorting is performed without acceleration control, then system simplicity is maintained, but image capture accuracy deteriorates due to battery movement variability
Solution Approach 1:
The patent applies preliminary acceleration control to bring batteries to a standard velocity before they enter the image capturing area. This preliminary action ensures consistent battery positioning and movement speed during capture, improving image quality without significantly complicating the overall system.
Solution Approach 2:
The system dynamically adjusts battery speed using an acceleration device that controls roller speeds in different zones. The conveyor belt includes an acceleration zone that increases battery speed to an optimal range for image capture, then maintains that speed through the detection area, ensuring consistent capture conditions.

AI summary
A cylindrical battery sorting system includes a host, a conveying device, a sorting device, an acceleration device, and a camera device. The conveying device is electrically connected to the host, includes rollers disposed side by side, and has a feeding area, an acceleration area, and a sorting area. The sorting device is electrically connected to the host and disposed corresponding to the sorting area. The acceleration device is electrically connected to the host and disposed in the acceleration area. The camera device is electrically connected to the host and disposed corresponding to the acceleration area. When a battery enters a capturing area, the camera device moves synchronously with rolling of the battery to capture an image of the rolling battery, and transmit the image back to the host to determine type of the battery. The sorting device places the battery into a corresponding recycling area according to the captured image.
