Self-Locking Parcel Shelves for Faster Truck Loading and Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current parcel delivery systems in trucks face inefficiencies due to the need for manual loading and unloading, leading to increased time and costs associated with delivery and retrieval processes.
Innovation Solution
An automated storage and retrieval system comprising a parcel inductor, conveyor, and extraction station, along with self-locking assemblies that secure storage units within bays, enabling efficient parcel management and transport within mobile settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual loading and unloading of parcels is used, then labor flexibility is maintained, but delivery time and operational costs increase
Solution Approach 1:
The system pre-organizes parcels into storage bays before delivery, with the conveyor system ready to automatically retrieve and deliver parcels to the extraction station. This preliminary organization eliminates the need for manual searching and sorting during delivery, directly reducing delivery time and improving efficiency.
Solution Approach 2:
The automated conveyor system serves itself by automatically transporting parcels from storage bays to the extraction station without human intervention. The system monitors parcel locations and autonomously manages the retrieval and delivery process, eliminating manual labor while maintaining continuous operation.
2Ease of operation
If storage units are easily removable from bays, then loading and unloading speed increases, but parcel security and system reliability decrease
Solution Approach 1:
The mechanical lock and key system is replaced with an automated interlocking mechanism featuring protrusions and recesses. This system automatically engages when storage units are placed in bays and can be released through the automated conveyor system, providing both security and ease of operation without manual intervention.
Solution Approach 2:
The interlocking feature acts as an intermediary between the storage unit and the bay, providing automatic engagement and disengagement. The protrusion-recess mechanism serves as a mediator that secures parcels during transport while allowing controlled access during loading and unloading operations.
3Extent of automation
If automated conveyor systems are implemented, then labor requirements decrease, but system complexity increases
Solution Approach 1:
The automated system is divided into distinct functional segments: storage bays with interlocking mechanisms, conveyor sections for transport, and an extraction station for delivery. Each segment operates independently but coordinates with others, making the complex system manageable through modular design and reducing overall system complexity.

AI summary
A self-locking assembly includes one or more shelves. Each of the shelves has dividers, which define storage bays that are adjacent to each other in a lateral direction and adjacent storage bays being spaced apart from each other by one of the dividers positioned therebetween, and a lock contained within each storage bay. The self-locking assembly also includes one or more storage units having a width that is a same as, or smaller than, a width of at least one of the storage bays. Each of the storage units has an upper surface, which transports item(s) supported thereon, and an interlocking feature that engages with the lock of one of the storage bays to resist removal of each storage unit from a corresponding one of the storage bays. Each storage unit can be inserted into and removed from a corresponding one of the storage bays in a longitudinal direction.
