Voice-Based Delivery Completion Recognition for Manual Scan-Free Handoffs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing delivery systems require manual registration of delivery completion by delivery personnel, which is burdensome and can lead to errors, resulting in inefficient delivery processes and extra man-hours for follow-ups.
Innovation Solution
A delivery support system that analyzes voice data from conversations between delivery personnel and customers to automatically recognize delivery completion and notify a server, eliminating the need for manual registration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual registration of delivery completion is required, then delivery system can track delivery status, but delivery personnel burden increases and delivery efficiency decreases
Solution Approach 1:
The delivery completion recognition unit automatically detects and registers delivery completion status by analyzing voice data from the delivery scene, enabling the system to self-record delivery information without requiring manual input from delivery personnel. This eliminates the burden of manual registration while maintaining accurate delivery status tracking.
Solution Approach 2:
The patent replaces the mechanical manual operation of terminal devices with automatic voice-based recognition and analysis. The delivery completion recognition unit processes voice data to automatically determine delivery completion, substituting the need for physical terminal operations with automated acoustic signal processing.
2Loss of information
If manual registration is used, then delivery information can be recorded, but delivery personnel may forget to register leading to inaccurate delivery time recording
Solution Approach 1:
The system performs preliminary voice data acquisition and analysis during the delivery process itself, capturing delivery completion information at the moment it occurs. This preliminary automatic recording ensures delivery time is accurately captured before any potential forgetting or manual registration errors can occur.
Solution Approach 2:
The notification unit provides feedback to the delivery system by automatically transmitting delivery completion information to the server. This closed-loop feedback mechanism ensures that delivery status is continuously updated without relying on manual registration, eliminating forgetting errors while maintaining operational simplicity.
3Productivity
If manual terminal operation is required for delivery registration, then delivery system maintains control over delivery process, but extra man-hours are spent on follow-up activities
Solution Approach 1:
The delivery support device automatically performs delivery registration and notification functions without requiring manual terminal operations. The system self-manages the delivery recording process, eliminating the need for follow-up activities to verify or correct manual registration omissions, thereby reducing both operational burden and follow-up time consumption.
4Ease of operation
If voice data analysis is implemented for automatic delivery recognition, then manual registration burden is reduced, but system complexity increases
Solution Approach 1:
The delivery completion recognition unit serves as an intermediary component that bridges voice data acquisition and delivery status determination. This modular intermediary design isolates the complexity of voice analysis within a dedicated functional unit, maintaining ease of operation for the overall system while managing complexity through functional decomposition.

AI summary
A in-vehicle process unit (25) of an in-vehicle device (9) supports a delivery person in a task of delivering a delivery item to a delivery destination. The in-vehicle process unit (25) analyzes voice data of conversation between the delivery person and a customer of the delivery destination or utterance of the delivery person when the delivery item is delivered, and recognizes that delivery of the delivery item is complete. Further, when recognizing that the delivery of the delivery item is complete, a delivery completion notification is sent to a predetermined notification target, such as a server (61) or the like.
