Guidance Devices for Package Sorting Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Human error in sorting packages in shipping warehouses leads to misplacement, causing delays and increased costs due to the reliance on manual identification of bins, where workers may incorrectly place packages based on labels.
Innovation Solution
A package management system utilizing guidance devices that communicate with an inventory tracking system to illuminate the correct bin for placement, eliminating the need for workers to read shipping labels by using event detecting devices, sensors, and wireless communication to ensure accurate sorting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If workers manually identify bins using shipping labels, then the system maintains simplicity and low cost, but human error increases leading to misplacement
Solution Approach 1:
The patent introduces an intermediary system consisting of guidance devices, sensors, and a central control system that mediates between the package and the worker. The guidance device receives package information, determines the correct bin, and provides visual guidance to the worker, eliminating the need for the worker to manually interpret labels while maintaining system simplicity through automated decision-making.
Solution Approach 2:
The system enables self-service by allowing packages to guide themselves to the correct bin through automated identification and guidance. Sensors read package information, the control system determines the destination bin, and visual indicators guide workers, reducing reliance on human judgment and manual label reading while maintaining operational simplicity.
2Productivity
If bins are stacked vertically with labels above each bin, then space utilization improves, but workers may place packages in the wrong bin due to visual confusion
Solution Approach 1:
The patent employs color-coded visual indicators on guidance devices that correspond to specific bins or bin groups. Different colors indicate different destination bins, providing intuitive visual cues that help workers quickly identify the correct bin among vertically stacked options, eliminating confusion while maintaining efficient vertical storage configuration.
Solution Approach 2:
The system adds a visual dimension to bin identification by implementing guidance devices with illuminated indicators that provide spatial and visual differentiation between bins. This dimensional enhancement allows workers to distinguish between vertically stacked bins more easily, maintaining space efficiency while improving placement accuracy through augmented visual information.
3Productivity
If automated package movement is implemented, then sorting speed increases, but the system cost and complexity increase significantly
Solution Approach 1:
The patent implements partial automation by automating only the identification and guidance functions while leaving the physical package movement to human workers. Sensors automatically read package information and the control system automatically determines destination bins, providing automated decision-making support without requiring full automated material handling infrastructure, thus achieving speed improvement with moderate complexity increase.

AI summary
Embodiments presented herein describe a package management system that uses guidance devices when transporting packages. In one embodiment, the package management system includes an event detecting device that detects a package transporting event such as when a package is sorted into a container, a container is moved from the warehouse to vehicle, a container is moved from a vehicle into a warehouse, or a package is delivered. For example, the event detecting device may trigger the event in response to a worker scanning a bar code, selecting a delivery route, or checking an electronic manifest. Once a container corresponding to the event is identified, a gateway identifies the guidance device assigned to that container and instructs the guidance device to illuminate a light disposed thereon.
