Reconfigurable Track Sorting Vehicles for Compact Mail Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual sorting of mail pieces and items in large organizations is labor-intensive and costly, with existing automated systems being either too expensive or ineffective due to size and diversity of mail volumes.
Innovation Solution
A compact automated sorting system using semi-autonomous delivery vehicles guided by a track with interchangeable sections, controlled by a central controller, which ensures items are sorted and delivered to appropriate bins while maintaining orientation, and includes manual or automatic input stations for determining item destinations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional automated sorting equipment is used, then sorting efficiency is improved, but cost increases significantly
Solution Approach 1:
The sorting system is divided into modular components: input station, delivery vehicles, track system with sections, and destination areas. Each component can be independently manufactured and assembled, reducing overall system cost while maintaining automated sorting efficiency.
Solution Approach 2:
The track includes interchangeable sections that can be reconfigured based on sorting needs. Delivery vehicles dynamically adjust their routes and destinations. This flexibility allows the system to handle diverse mail volumes efficiently without requiring a complete system redesign, thereby maintaining productivity while controlling costs.
2Productivity
If existing automated sorting systems are used, then sorting capability is improved, but system size becomes excessive
Solution Approach 1:
The system uses a multi-level track structure with sections that can be arranged in different spatial configurations. Delivery vehicles travel along these tracks in three-dimensional space, allowing the system to achieve high sorting capability within a compact footprint by utilizing vertical and lateral dimensions rather than only horizontal expansion.
3Measurement precision
If automated sorting is implemented for diverse mail volumes, then sorting accuracy is improved, but system complexity increases
Solution Approach 1:
The delivery vehicles are designed as universal carriers that can transport various types of mail items. The track system with interchangeable sections can be configured for different sorting patterns. The controller universally manages all vehicles and destinations using the same control logic, thereby achieving high sorting accuracy for diverse mail volumes without proportionally increasing system complexity.
4Device complexity
If manual sorting is performed, then system simplicity is maintained, but labor intensity and time consumption increase
Solution Approach 1:
The system employs delivery vehicles that autonomously navigate the track, receive items at input stations, and deliver them to correct destination areas without human intervention. The controller automatically manages vehicle routing and coordination. This self-service capability eliminates manual sorting labor while keeping the physical system relatively simple and significantly reduces time consumption.

AI summary
A method and apparatus are provided for sorting items to a plurality of sort destinations. The items are loaded onto one of a plurality of independently controlled delivery vehicles. The delivery vehicles follow a track that guides the delivery vehicles to the sort destinations, which are positioned along the track. Once at the appropriate sort destination, the delivery vehicle ejects the item to the sort destination and returns to receive another item to be delivered.
