Storage Logistics with Under-Access Transfer Vehicles for Faster Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage logistics systems face inefficiencies in ex-warehousing and warehousing processes, with shelf-to-person systems being time-consuming and laborious, while shuttle stereoscopic storage systems are costly and require high site heights, and low-cost alternatives are not mature enough to meet efficiency requirements.
Innovation Solution
A storage logistics system featuring a shelf with horizontal and vertical beams, a movable articles access mechanism, and a transfer vehicle, which includes a temporary storage mechanism and a fork mechanism that allows the transfer vehicle to pass under the access mechanism, ensuring unobstructed travel and efficient article handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a shelf-to-person system is used for ex-warehousing and warehousing, then articles can be stored and retrieved, but the process is time-consuming and laborious due to moving the whole shelf
Solution Approach 1:
The system divides the shelf structure into stationary support beams and movable storage units. The articles access mechanism can independently move to different storage positions without requiring the entire shelf to be moved, thus segmenting the movement function from the storage structure itself.
Solution Approach 2:
The articles access mechanism is designed to be movable relative to the shelf, allowing dynamic access to different storage positions. This dynamic capability enables the system to retrieve articles from any location without moving the entire shelf structure, significantly reducing the time and labor required.
2Productivity
If a shuttle stereoscopic storage system is used, then articles can be ex-warehoused and warehoused, but the cost is high and the height reaches 15-20 meters requiring high site height
Solution Approach 1:
The system transitions from vertical stacking (15-20 meters height) to horizontal arrangement with the articles access mechanism moving along the shelf. This dimensional change allows article handling capability to be achieved without requiring extreme vertical space, reducing the site height requirement while maintaining productivity.
3Ease of manufacture
If low-cost container ex-warehousing and warehousing systems are used, then entry is easier and cost is lower, but the systems are not mature and overall efficiency is low
Solution Approach 1:
The articles access mechanism is designed with movable components including a movable platform and adjustable forks that can dynamically position articles. This dynamic design, combined with the control system, achieves high efficiency while maintaining relative simplicity and cost-effectiveness compared to mature but complex automated systems.
Solution Approach 2:
The system incorporates automated control where the control device coordinates the articles access mechanism to automatically retrieve and store articles without manual intervention. This self-service capability improves efficiency while keeping the system structure relatively simple and cost-effective.
