Delivery Support Device Using Weight Checks to Locate Package Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems struggle to identify the transportation process in which a loss or theft of a package occurs, making it difficult to determine the location of liability and reduce the risk of such incidents.
Innovation Solution
A delivery support device that acquires and compares weight data at different time points during the transportation process to detect any loss or theft by determining weight discrepancies, thereby identifying the transportation process in which the loss or theft occurred.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If weight monitoring is implemented at multiple time points during transportation, then the ability to identify loss or theft incidents is improved, but the device complexity and measurement requirements increase
Solution Approach 1:
The system performs preliminary weight measurement at the departure point before transportation begins, establishing a baseline weight. This preliminary action enables subsequent comparison with arrival weight to detect any loss or theft incidents during transit, resolving the contradiction by implementing minimal but strategic measurement points rather than continuous monitoring.
Solution Approach 2:
The transportation process is segmented into distinct phases (departure, transit, arrival) with weight measurements taken at key transition points. This segmentation allows the system to identify exactly where in the transportation chain loss or theft occurred, improving detection capability while avoiding the need for continuous monitoring throughout the entire process.
2Measurement precision
If weight data is collected at multiple transportation checkpoints, then the precision of identifying when loss or theft occurred is improved, but the measurement requirements and data processing burden increase
Solution Approach 1:
The system extracts only the essential weight information at departure and arrival points, comparing these two key data points to determine if loss or theft occurred. This extraction approach provides sufficient precision to identify the transportation phase where incidents occurred without the burden of collecting and processing continuous weight data throughout the entire transportation journey.
3Reliability
If comprehensive weight monitoring is implemented throughout the transportation process, then the ability to detect loss or theft is improved, but the cost and operational complexity increase
Solution Approach 1:
The system performs preliminary weight recording at departure and final weight measurement at arrival, using these preliminary actions to detect any loss or theft. This approach maintains high detection capability while preserving operational simplicity by avoiding the need for continuous monitoring equipment and personnel throughout the transportation process.

AI summary
The delivery support device supports delivery of the article. The delivery support device includes a control unit configured to acquire first weight data indicating a weight of an article measured at a first time point in a transportation process of an article and second weight data indicating a weight of the article measured at a second time point after the first time point, and determine whether to notify the user of a warning based on a result of comparing the weight indicated by the first weight data and the weight indicated by the second weight data.
