Delivery Robot Shelf Partitioning for Secure Multi-Section Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Delivery robots face challenges in safely transporting items over uneven terrain and navigating obstacles while maintaining the security of stored goods, especially when the items are placed on shelves, and there is a need for efficient use of internal space as they move items over long distances.
Innovation Solution
A delivery robot equipped with a middle shelf that can be partitioned into upper and lower sections, using elastic sensors to detect the shelf's mounting and operate doors individually for each section, and an internal camera to determine item presence, allowing for safe storage and delivery while optimizing space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the storage space is divided into multiple sections with individual doors, then the security and safety of stored items is improved, but the device complexity increases
Solution Approach 1:
The storage space is divided into multiple sections (upper and lower storage sections) with separate doors for each section. This segmentation allows independent access to different storage areas, improving security and safety by enabling selective door operation based on item location and reducing the risk of complete loss if one door fails.
Solution Approach 2:
The door operation system is designed to handle multiple functions: it can operate individual doors independently, operate multiple doors simultaneously, and adapt its operation based on sensor feedback about item presence and shelf configuration. This multi-functionality resolves the complexity issue by creating a unified control system that manages diverse door operations through a single intelligent controller.
2Productivity
If the delivery robot moves over uneven terrain and long distances, then the delivery capability is improved, but the risk of items falling from shelves increases
Solution Approach 1:
The shelf system is designed to be dynamic and adaptive. The controller receives feedback from sensors about the robot's movement status and adjusts door operations accordingly. During movement, the controller can keep doors closed to secure items, and only open them when the robot is stationary and safe, thus adapting the storage system's state to the robot's operational phase.
Solution Approach 2:
The system incorporates sensors that detect the robot's movement status, shelf position, and item presence, providing continuous feedback to the controller. This feedback mechanism enables the controller to make real-time decisions about door operation, ensuring doors remain closed during movement to prevent item falling, and only opening when safety conditions are met.
3Quantity of substance
If the internal space is fully utilized with shelves and partitions, then the storage capacity is improved, but the ease of access to items deteriorates
Solution Approach 1:
The storage space is segmented into multiple accessible sections with individual doors. This segmentation allows items to be stored densely in divided sections while maintaining ease of access by enabling selective opening of only the required section's door, rather than accessing the entire storage space.
Solution Approach 2:
Different sections of the storage space can be optimized for different item types and access frequencies. Frequently accessed items can be placed in sections with easier access characteristics, while less frequently accessed items can be stored in more compact sections. Each section's door operation can be independently optimized based on the specific access patterns and item characteristics of that local area.
