Innovation Solution
An automated system for loading postal items into a rack unit of a delivery vehicle, utilizing a sorting conveyor, delivery conveyor, and automatic loading units, with integrated detection and orientation mechanisms to optimize space utilization and sequencing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual loading is used, then flexibility and simplicity are maintained, but loading time increases and productivity decreases
Solution Approach 1:
The system segments the loading process into distinct functional modules: a sorting conveyor for organizing postal items, a delivery conveyor for transporting items, and an automatic loading unit for placing items into rack units. This modular segmentation enables automated high-speed loading while keeping each component relatively simple and maintainable.
Solution Approach 2:
The sorting conveyor performs preliminary sorting and organizing of postal items before they reach the loading point. The system pre-sequences items according to delivery routes, so that when items reach the automatic loading unit, they are already prepared for efficient loading into the rack unit in the correct delivery sequence.
2Object-affected harmful factors
If manual handling is used, then operational simplicity is maintained, but the risk of damage to postal items increases
Solution Approach 1:
The system replaces manual mechanical handling with an automated mechanical system consisting of conveyors and an automatic loading unit. This substitution eliminates human error and rough handling, reducing damage risk while implementing controlled, gentle mechanical transfer of postal items through the loading process.
Solution Approach 2:
The automatic loading unit performs the loading function autonomously without human intervention. The system self-regulates the transfer and placement of postal items into rack units, ensuring consistent handling standards and minimizing damage through programmed precise positioning and controlled placement mechanisms.
3Loss of time
If items are loaded in random order, then loading speed is maintained, but delivery time increases due to disorganized sequencing
Solution Approach 1:
The sorting conveyor performs preliminary sequencing of postal items according to their delivery destinations and routes before items reach the loading point. This pre-organization ensures that items are loaded into the rack unit in the correct delivery sequence, eliminating the need for drivers to search for packages and enabling immediate sequential delivery.
Solution Approach 2:
The system incorporates detection devices that identify postal items and provide feedback to the control unit about item characteristics and destination requirements. The control unit uses this feedback to dynamically adjust the sorting and sequencing process, ensuring items are correctly ordered for delivery while optimizing loading efficiency.
4Quantity of substance
If space utilization is not optimized, then loading simplicity is maintained, but the number of parcels per trip decreases
Solution Approach 1:
The automatic loading unit incorporates adjustable and adaptable loading mechanisms that can dynamically adjust to different postal item sizes, shapes, and weights. The system optimizes space utilization by adapting the placement strategy for each item, maximizing the number of parcels that can be loaded into the rack unit while maintaining organized sequencing and efficient space occupation.
