Package Tags Using RSSI for Delivery Group Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a risk of package mix-ups or omissions during multiple package deliveries to a customer's residence, leading to customer dissatisfaction and increased delivery costs, as existing systems lack effective methods to accurately confirm the correct grouping of packages.
Innovation Solution
A system employing radio tags with Package ID and Group Sub-ID codes is used to prevent errors by transmitting signals that are received by a delivery person's device or a remote server, utilizing techniques like RSSI and long-range radio transmission to determine the proximity and correct grouping of packages based on signal strength and location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If manual package verification is used during delivery, then delivery cost is reduced, but the accuracy of package grouping and delivery reliability deteriorates due to human error
Solution Approach 1:
The patent replaces manual mechanical verification with an automated electronic system using radio frequency tags and signal strength measurement. The system automatically detects package locations and verifies grouping accuracy without human intervention, eliminating human error while maintaining low operational costs.
Solution Approach 2:
The system enables self-verification where packages equipped with radio tags automatically transmit their location and grouping information. The delivery system autonomously confirms correct package grouping without requiring manual checking, making the verification process automatic and reliable.
2Reliability
If automated package verification systems are implemented, then delivery reliability improves, but device complexity and implementation cost increase
Solution Approach 1:
The radio tags serve multiple functions: identification, location tracking, and grouping verification. This multi-functionality reduces the need for separate systems for each task, simplifying overall system complexity while maintaining high reliability through a single integrated solution.
Solution Approach 2:
The system uses changes in radio signal strength parameters to determine package proximity and grouping. By leveraging existing radio frequency technology and measuring signal strength variations, the system achieves accurate verification without complex mechanical or electronic mechanisms.
3Measurement precision
If radio tags are attached to all packages, then package tracking accuracy improves, but manufacturing cost and device complexity increase
Solution Approach 1:
The radio tags are designed as low-cost, disposable components that can be easily attached to packages. Their inexpensive nature allows universal application across all packages without significantly increasing manufacturing costs, while providing precise location and grouping verification throughout the delivery process.

AI summary
A method of managing delivery of a group of packages to a customer delivery address. A radio transceiver establishes a communication link between a tag and a computing device. The tag is associated with a package, the package being among a group of packages to be delivered to the customer delivery address. A radio signal is received at the computing device over the link. The radio signal is representative of tracking information associated with the package, the tracking information includes a unique package code and a unique group identification code. The signal strength of the radio signal is determined. The computing device determines that the package associated with the tag belongs with the group of packages based at least in part on proximity of the tag relative to the computing device and a unique group identification code associated with the customer delivery address.
