Rotating Body Conveyor for Freight Sorting Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In freight transportation using logistics mobility devices, efficiently managing and moving freights to multiple delivery destinations is challenging due to the mixing of nearby and distant delivery freights, leading to prolonged unloading times.
Innovation Solution
A mobility device equipped with a conveyor system featuring rotating bodies whose rotational direction, torque, and angle are controlled, along with a user interface and controller for wireless communication, allows for quick and convenient movement of freights by detecting changes in pressure to update freight lists and transmit movement commands to control the conveyor system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If freights from nearby and distant delivery destinations are mixed in the loading box, then the loading box can be efficiently utilized, but it becomes difficult and time-consuming to retrieve specific freights
Solution Approach 1:
The loading box is divided into multiple loading zones (first loading zone and second loading zone) with different heights. Freights are segmented and placed in different zones based on their delivery destinations, allowing efficient space utilization while enabling quick retrieval by accessing the appropriate zone.
Solution Approach 2:
The patent introduces a vertical dimension by creating loading zones at different heights within the loading box. The first loading zone is positioned higher than the second loading zone, allowing freights to be stacked vertically and retrieved efficiently without horizontal interference.
2Productivity
If a conveyor device with multiple rotating bodies is used to move freights, then freight movement efficiency is improved, but the device complexity increases
Solution Approach 1:
The conveyor device uses the weight of the freights themselves to drive the rotation of the rotating bodies. When a freight is placed on a rotating body, its weight automatically causes the rotating body to rotate, moving the freight without requiring external motors or complex control systems for each individual mover.
Solution Approach 2:
The rotating bodies serve multiple functions: they act as transport carriers, automatic movers (using freight weight), and positioning mechanisms. This multi-functionality reduces the need for separate components, simplifying the overall system while maintaining high freight movement efficiency.
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 enables faster and more efficient movement of freights within the loading box, improving logistics efficiency by allowing users to easily designate and move freights to their intended destinations through a user-friendly interface, reducing unloading times and optimizing freight management.
Implementation Method 1
The controller is configured to detect the loading of a new freight or the unloading of an existing freight on the conveyor device from a change in pressure applied to the plurality of rotating bodies
