Parcel Distribution Hub-and-Spoke System Lateral Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current parcel distribution systems face inefficiencies due to repeated sorting steps and inflexible reloading processes, leading to delays and suboptimal use of truck capacity, as they often require multiple intermediate sorting stations and fixed departure times.
Innovation Solution
A hub-and-spoke topology-based distribution system with a central terminal for single-stage sorting, where parcels are loaded across the truck bed from the lateral side, utilizing a computer processing system to optimize routing and loading, and secondary trucks pick up containers from transfer points along optimized routes, allowing flexible reloading and precise parcel positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If parcels are sorted at multiple intermediate sorting stations, then delivery coverage is improved, but sorting time and delivery delays increase
Solution Approach 1:
The patent extracts the sorting function from multiple intermediate stations and concentrates it entirely at the central hub. Parcels are sorted once at the hub into containers assigned to specific delivery zones, eliminating repeated sorting at intermediate stations while maintaining comprehensive delivery coverage through the container-based distribution network.
Solution Approach 2:
The patent segments the delivery network into zones, with each container assigned to a specific zone. This segmentation allows parcels to be sorted once at the hub into zone-specific containers, then distributed efficiently through the container network without requiring intermediate sorting, thus reducing sorting time while maintaining delivery coverage.
2Reliability
If trucks depart at fixed times, then operational reliability is improved, but truck capacity utilization deteriorates
Solution Approach 1:
The patent implements preliminary action by pre-assigning parcels to containers based on their final delivery zones before truck departure. This allows containers to be prepared in advance at the hub, enabling flexible loading that maximizes truck capacity while maintaining reliable scheduled departures. The computer system calculates optimal container assignments ahead of time.
Solution Approach 2:
The patent introduces dynamics by allowing flexible container loading arrangements within trucks based on actual parcel volumes and destinations. Containers can be positioned and loaded dynamically to optimize space utilization, while the overall departure schedule remains fixed and reliable. The system adapts loading configurations rather than following rigid patterns.
3Ease of operation
If containers are loaded traditionally from the rear of the truck, then loading simplicity is improved, but loading efficiency and flexibility deteriorate
Solution Approach 1:
The patent fundamentally changes the loading dimension by enabling containers to be loaded from the lateral sides of the truck bed rather than only from the rear. This dimensional change allows simultaneous loading of multiple containers by different operators or machines, dramatically improving loading efficiency while maintaining operational simplicity through standardized container handling.
Solution Approach 2:
The patent merges multiple loading operations into a single coordinated process by orienting containers across the truck bed width. This allows simultaneous loading from multiple lateral positions, combining the efforts of multiple loading points into one efficient operation, thereby improving overall loading efficiency without complicating the process.
4Productivity
If parcels are loaded without optimized positioning, then loading speed is improved, but delivery efficiency deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-calculating and pre-positioning parcels within containers according to their final delivery sequences. The computer system determines the optimal loading order and positions parcels accordingly before truck departure. This eliminates the need for time-consuming repositioning during delivery while maintaining high loading speed through automated or pre-planned loading procedures.

AI summary
A parcel distribution system with special emphasis on a rational system avoiding delays e.g. caused by repeated sorting steps and reloading of trucks and containers. A hub-and-spoke topology is being used as the backbone of the distribution system according to the invention, which means that all sorting is performed in the hub or central terminal only. Containers to be loaded with the sorted parcels are oriented across the length of the truck bed for entering parcels from at least one lateral side of the truck bed.
