Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a manual loading system is used, then the device complexity is low, but the productivity is low and the operation is inefficient
Solution Approach 1:
The system is divided into distinct functional modules: landing pad for UAV reception, elevating subsystem with lifting board for vertical transport, and compartment subsystem for package storage. Each module operates independently but coordinates through standardized interfaces, enabling efficient package handling while maintaining manageable system complexity through modular design.
Solution Approach 2:
The lifting board acts as an intermediary component between the landing pad and the compartments. It temporarily holds packages transferred from UAVs and facilitates their vertical movement to the appropriate storage compartments, enabling efficient package transfer without requiring direct complex mechanisms between all components.
2Ease of operation
If the lifting board is positioned at the center hole, then the UAV can land safely and the package transfer is efficient, but the structural complexity increases
Solution Approach 1:
The lifting board positioned at the central hole of the landing pad serves multiple functions: it provides a stable landing surface for UAVs, acts as a temporary holding platform for packages during transfer, and facilitates vertical elevation to compartments. This multi-functional design simplifies the overall system by combining several operations into a single component.
Solution Approach 2:
The lifting board is designed to be leveled with the flat platform when the UAV is landing, creating a continuous, level surface that eliminates height differences and facilitates smooth package transfer from the UAV to the lifting board without requiring additional adjustment mechanisms.
3Productivity
If multiple compartments are used for package storage, then the productivity and organization are improved, but the device complexity and space requirements increase
Solution Approach 1:
The compartments are arranged vertically one above the other, utilizing the vertical dimension for storage organization. This vertical stacking approach allows multiple storage compartments to be accommodated within a compact footprint, improving package sorting efficiency while minimizing the horizontal space required for the compartment subsystem.

AI summary
A system for receiving a package from an unmanned aerial vehicle that includes a landing pad comprises a flat platform with a central hole, an elevating subsystem comprises a lifting board and a lifting mechanism, and a compartments subsystem comprises plurality of compartments, one above the other, each of which has a pushing rod with an actuator. The flat platform is suitable for the aerial vehicle to land on it. The lifting board is positioned in the central hole in such a way that the lifting board can be leveled with the flat platform when the aerial vehicle is landing, and the lifting board is suitable to the aerial vehicle to place the package on it. The lifting mechanism can lift up and lower down the lifting board that can stop in front of each compartment and the pushing rod can push the package to the compartment.
