Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current three-dimensional sorting systems face issues with unreliable delivery of goods into goods baskets during the sorting process, leading to inefficiencies and failed deliveries.
Innovation Solution
A sorting control method for a three-dimensional sorting robot that includes state acquisition, delivery, and confirmation steps, utilizing scanning or image acquisition devices to ensure accurate positioning and successful delivery of goods into target baskets, with multiple confirmation attempts if initial delivery fails.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a three-dimensional sorting system is implemented to improve sorting efficiency, then sorting capacity and speed are enhanced, but delivery reliability deteriorates due to goods failing to enter baskets
Solution Approach 1:
The patent implements a feedback mechanism where the scanning device detects whether goods have successfully entered the basket, and this information is fed back to the control device. When delivery failure is detected, the system automatically triggers a retry mechanism, resolving the reliability issue while maintaining high sorting efficiency
Solution Approach 2:
The system performs preliminary detection of basket position and state before delivery occurs. The scanning device pre-scans the target position and basket availability, allowing the system to prepare and adjust delivery parameters in advance, thereby improving both efficiency and reliability
2Reliability
If multiple confirmation attempts are implemented to improve delivery reliability, then delivery success rate increases, but time consumption increases
Solution Approach 1:
The system implements a multi-level confirmation process that can skip unnecessary detection steps. When the first detection confirms successful delivery, subsequent confirmation steps are skipped, reducing time consumption while maintaining high delivery success rate through selective verification
3Measurement precision
If scanning or image acquisition devices are used to detect delivery status, then delivery accuracy improves, but device complexity increases
Solution Approach 1:
The patent introduces a scanning device or image acquisition device as an intermediary between the delivery mechanism and the control system. This intermediary automatically detects delivery status and transmits information to the control device, improving delivery accuracy while keeping the overall system complexity manageable through automated detection rather than complex mechanical feedback mechanisms

AI summary
A sorting control method for a three-dimensional sorting robot, a three-dimensional sorting robot and a related device are provided. The method comprises: a state acquisition step, involving acquiring the state of a target goods basket unit of the current sorting shelf; a delivery step, involving controlling, when it is confirmed that the target goods basket unit is available, an unloading mechanism of a three-dimensional sorting robot to execute a first delivery action; a determination step, involving determining whether goods to be delivered enter the target goods basket unit, and when a delivery failure occurs, controlling the unloading mechanism of the three-dimensional sorting robot to execute a second delivery action; and a confirmation step, involving executing the determination step once or multiple times, until it is confirmed that the goods to be delivered are delivered into the target goods basket unit.
