Existing logistics systems face challenges with automated delivery vehicles, such as identifying and authenticating users, ensuring correct loading and unloading of items, and preventing errors that can lead to delays and spoilage, particularly when users have their hands full or are unable to interact with the device.
Innovation Solution
A method and apparatus for enhanced automated access to personal delivery devices, utilizing external sensors to detect and authenticate authorized participants, and internal sensors to confirm transactions, with a controller managing access and corrective actions to prevent errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated personal delivery devices are deployed to reduce costs and improve efficiency, then productivity increases, but reliability decreases due to authentication and item verification problems
Solution Approach 1:
The patent replaces manual authentication methods (physical interaction with delivery device) with automated sensor-based detection and recognition systems. The sensor array detects persons and items, the processor compares detected items against expected items, and the system automatically authenticates participants and verifies item correctness, eliminating the need for manual verification while maintaining high reliability
Solution Approach 2:
The delivery device performs self-authentication and self-verification functions by automatically detecting persons, identifying items, comparing them against expected parameters, and determining whether transactions should proceed. The system serves itself by autonomously verifying item correctness and participant authorization without requiring manual intervention
2Reliability
If physical interaction devices (keypads, buttons) are required for authentication, then reliability improves through direct user confirmation, but ease of operation worsens when users have hands full
Solution Approach 1:
The patent eliminates mechanical interaction devices like keypads and buttons by replacing them with sensor-based detection systems. The sensor array automatically detects persons approaching the device, identifies them through recognition algorithms, and authenticates them without requiring physical contact. This substitution maintains authentication reliability while completely removing the barrier for users with occupied hands
Solution Approach 2:
The patent introduces sensors and processors as intermediaries between the user and the authentication system. Instead of direct physical interaction, the sensor array acts as an intermediary that detects user presence and characteristics, the processor analyzes this data to verify identity, and the system responds accordingly. This intermediary chain maintains security while enabling hands-free operation
3Measurement precision
If manual verification of loaded items is performed, then measurement precision improves for item verification, but loss of time increases due to additional verification steps
Solution Approach 1:
The patent implements continuous item verification by having the sensor array detect items as they are loaded onto the device. The processor continuously compares detected items against the expected item list in real-time, providing ongoing verification rather than discrete manual checks. This continuous process maintains high measurement precision while eliminating idle verification time
Solution Approach 2:
The system performs preliminary verification by pre-loading the expected item list into the processor before the delivery transaction begins. As items are loaded, the system already has the verification criteria ready and can immediately compare detected items against expected parameters, eliminating the time required for post-loading verification and maintaining precision through pre-prepared verification protocols
4Device complexity
If error detection is performed after the delivery device has moved to the next location, then device complexity is reduced, but loss of time and substance increases due to spoilage and corrective dispatches
Solution Approach 1:
The patent implements immediate feedback by having the processor continuously monitor detected items against expected items during the loading process. When a mismatch is detected, the system provides instant feedback by identifying the error and can trigger corrective actions at the current location rather than waiting until the next location. This feedback loop maintains relatively simple device architecture while preventing time loss and spoilage through real-time error detection
Solution Approach 2:
The system performs preliminary error detection during the loading process itself, before the device departs. The sensor array and processor verify items as they are loaded, detecting errors in advance of departure. This preliminary detection prevents the need for complex post-departure verification systems and eliminates the time loss and spoilage associated with discovering errors after the device has already moved to the next location
Data Source
AI summary
Systems, apparatus, and methods are described for providing enhanced automated access to a dispatched personal delivery device that can transport a shipment item within the device according to a dispatched logistics transaction. External sensors (e.g., cameras, proximity sensors, microphones) on the delivery device detect a person outside the dispatched personal delivery device. A controller on the delivery device authenticates that the detected person is an authorized participant to the dispatched logistics transaction based upon sensor data generated by the external sensors. An actuator on the dispatched personal delivery device provides access to within the dispatched personal delivery device to permit the dispatched logistics transaction by the detected person when the detected person has been authenticated to be the authorized participant to the dispatched logistics transaction. The delivery device may then auto-confirm the transaction using internal sensors, and interact with a server, which may instruct the delivery device with corrective actions.
