Goods Shelf Shuttle Vertical Access Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost of using multiple shuttles for each layer of a goods shelf in warehouse logistics, due to the need for individual shuttles to access goods in different layers.
Innovation Solution
A goods shelf shuttle system that includes a vehicle body, an access device, and a lifting device, where the access device has a fixed part and a mobile part that can telescopically move, and the lifting device allows the fixed part to move vertically, enabling the access device to extend from or retract into the shuttle's accommodating chamber.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If each layer of the shelf is equipped with a shuttle to access goods, then the accuracy and speed of goods transportation is improved, but the number of shuttles required increases and production cost becomes high
Solution Approach 1:
The patent applies multi-functionality by enabling a single shuttle to perform the function of multiple shuttles through the lifting device. The lifting device allows the access device to move vertically between different layers, making one shuttle capable of accessing goods at multiple layer positions, thus replacing the need for separate shuttles for each layer while maintaining the productivity benefit of automated access
2Productivity
If each layer of the shelf is equipped with a shuttle to access goods, then the accuracy and speed of goods transportation is improved, but the production cost increases
Solution Approach 1:
The lifting device enables one shuttle to serve multiple layers, reducing the total number of shuttles needed from N (one per layer) to 1 (shared across all layers). This significantly reduces production costs while maintaining the automated goods transportation capability across all layers through vertical movement of the access device
3Quantity of substance
If a single shuttle is used to access multiple layers, then the number of shuttles is reduced and cost is lowered, but the device complexity increases due to the lifting mechanism
Solution Approach 1:
The access device is nested within the vehicle body, and the lifting device integrates the vertical movement function into the existing shuttle structure. The access device can be retracted into the vehicle body when not in use, and the lifting device is connected between the fixed part and vehicle body, creating a compact integrated structure that minimizes space occupation while providing multi-layer access capability
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution reduces the number of shuttles required and lowers production costs by allowing a single shuttle to access goods in multiple layers through vertical movement of the access device, thereby improving efficiency and reducing costs.
Implementation Method 1
the lifting device is connected between the fixed part and the vehicle body, the lifting device is configured to drive the fixed part to move along a vertical direction
Implementation Method 2
the mobile part can telescopically move relative to the fixed part
