Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous mobile picking robots face instability issues when securing inhomogeneous packages of varying sizes on load-carrying devices, leading to impaired container stability during fully automated picking processes.
Innovation Solution
The integration of a load securing device with a handling manipulator, equipped with a winding roll and stretchable wrapping material, allows for immediate securing of packages after picking, enhancing stability and enabling efficient stacking and transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If packages are picked and stacked on a load-carrying device without immediate securing, then the picking operation can proceed quickly, but the stability of the packages on the load carrier is compromised
Solution Approach 1:
The load securing device applies wrapping material to secure packages to the load carrier immediately after stacking, performing the securing action in advance before transport. This preliminary action prevents instability during motion without requiring manual intervention after stacking.
Solution Approach 2:
The handling manipulator performs dual functions: stacking packages and then automatically securing them with the load securing device. The system serves itself by integrating the securing function into the automated picking robot, eliminating the need for separate manual securing operations.
2Stability of the object's composition
If a load securing device is integrated with the handling manipulator, then package stability is improved, but the device complexity increases
Solution Approach 1:
The load securing device is integrated with the handling manipulator, combining stacking and securing functions into a single robotic arm system. This merging reduces the need for separate devices and manual operations, despite increasing the manipulator's structural complexity.
Solution Approach 2:
The handling manipulator is designed to perform multiple functions: picking packages, stacking them on the load carrier, and then securing them with the integrated load securing device. This multi-functionality consolidates operations that would otherwise require separate systems.
3Stability of the object's composition
If wrapping material is applied to secure packages, then container stability is enhanced, but the time required for the picking process increases
Solution Approach 1:
The load securing device operates continuously during the picking process, securing packages immediately after they are stacked. This continuous action eliminates idle time and ensures stability is maintained throughout the entire picking and transport operation without interrupting the workflow.
