Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional drop-off points are used without clear markings, then device complexity is reduced, but delivery accuracy deteriorates
Solution Approach 1:
The system transitions from 2D map-based navigation to 3D spatial mapping with vertical layering, enabling precise drop point identification by adding depth information and multiple visualization layers to the navigation system
Solution Approach 2:
Signal-emitting tags are introduced as intermediary objects between the package and the delivery worker, providing detectable markers that enable accurate drop point identification without requiring complex physical infrastructure changes
2Measurement precision
If signal-emitting tags and phased antenna arrays are deployed, then delivery accuracy is improved, but device complexity increases
Solution Approach 1:
The signal-emitting tags autonomously transmit their location information without requiring active scanning or complex interrogation sequences, reducing the processing burden on the phased antenna array and simplifying the overall system operation
Solution Approach 2:
The phased antenna array continuously maintains tracking of signal-emitting tags before delivery events occur, establishing spatial awareness in advance so that drop point identification is immediate and requires no complex real-time computation during the actual delivery moment
3Productivity
If real-time 3D mapping is implemented, then delivery efficiency is improved, but use of energy increases
Solution Approach 1:
The system updates 3D map data and package location information at periodic intervals rather than continuously, reducing computational load and energy consumption while maintaining sufficient real-time awareness for efficient delivery operations
Solution Approach 2:
The phased antenna array tracks only relevant signal-emitting tags within the current delivery context rather than monitoring all possible signals in the environment, reducing processing requirements and energy usage while maintaining delivery efficiency

AI summary
A system is disclosed for identifying a drop point for packages using augmented reality (AR) and/or virtual reality (VR) devices. The system comprises packages with signal-emitting tags, such as RFID tags. The system includes a wireless base station with a phased antenna array and a physical location detection apparatus for 3D mapping. The system further comprises a signal processing module, a location module, and an overlap module which process and convert the detected signals into location data. This data is then transmitted to an AR/VR Device for real-time visualization and interaction. The AR/VR device includes an assist module to assist a package delivery person in delivering the tagged packages to the drop point.
