Projection Instruction Device for Parcel Sorting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing volume of parcel circulation and diversity of parcel types pose challenges for efficient and precise sorting, as manual sorting is time-consuming and prone to errors, and existing automated systems are not adequately equipped to handle the growing demand.
Innovation Solution
A parcel sorting system incorporating a projection instruction device that uses a label reader, distance image sensor, and projector to generate and display projection images on parcels based on their identification information and position, guiding workers on sorting directions and locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual sorting is used, then flexibility in handling diverse parcel types is maintained, but sorting speed and productivity are reduced
Solution Approach 1:
The system enables parcels to be automatically identified and sorted through self-service mechanisms: label readers automatically read parcel identification information, image sensors automatically capture parcel images, and the system automatically determines sorting destinations and controls projector operations without manual intervention for each parcel
Solution Approach 2:
The patent replaces manual mechanical sorting operations with an automated optical and computational system. Instead of workers manually reading labels and deciding parcel destinations, the system uses label readers, image sensors, and a processor to automatically identify parcels, determine sorting destinations, and guide workers or sorting mechanisms through projected images
2Productivity
If automated sorting systems are implemented, then sorting speed is improved, but system complexity increases
Solution Approach 1:
The system integrates multiple functions into a unified platform: the image sensor serves both for parcel identification and position detection, the processor handles both image processing and sorting decision-making, and the projector provides both visual guidance and sorting instructions. This multi-functionality reduces the need for separate dedicated devices for each function
Solution Approach 2:
The projector acts as an intermediary between the automated identification system and the physical sorting action. It translates digital sorting decisions into visual guidance that workers can immediately understand and act upon, bridging the gap between automated processing and manual execution
3Measurement precision
If real-time tracking and projection are implemented, then sorting precision is improved, but processing time increases
Solution Approach 1:
The system performs preliminary actions by continuously capturing parcel images and pre-processing them while parcels are in transit. The processor prepares sorting decisions in advance based on read identification information and pre-processed images, so that when a parcel reaches the sorting point, the decision is already ready and only projection and execution are needed
Solution Approach 2:
The system maintains continuous operation by continuously capturing images, continuously processing data, and continuously projecting guidance information. The image sensor and processor operate without interruption throughout the sorting process, eliminating idle time and ensuring that sorting decisions are always ready when needed

AI summary
There is provided a projection instruction device which generates a projection image to be projected on a parcel based on an image including the parcel and parcel identification information specifying the parcel in the image, the device including: a processor; and a memory, in which by cooperating with the memory, the processor determines a specific area in which the parcel is picked up based on the parcel identification information, and in a case where the parcel is present in the specific area, the processor projects the projection image.
