Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional reverse-triangle positioning approach with funnel-shaped landing dock is used, then UAV can be guided to slide onto docking station, but landing area must be large and fragile parts may be damaged due to uncontrollable contacts
Solution Approach 1:
The patent replaces the mechanical funnel-based guidance system with a magnetic field-based positioning system. The magnetic device generates a magnetic field that guides the UAV to the docking station without physical contact, eliminating the need for a funnel-shaped structure and preventing mechanical damage to fragile components during landing.
Solution Approach 2:
The patent introduces a magnetic field as an intermediary between the docking station and the UAV. The magnetic device creates a magnetic field that acts as a non-contact guide, allowing the UAV to be attracted to and positioned at the docking station without direct mechanical interaction, thus avoiding damage to fragile parts.
2Measurement precision
If down-viewing positioning approach with high precision visual element and high performance processing module is used, then landing position can be determined, but equipment size and weight increase detrimenting mounting ability
Solution Approach 1:
The patent replaces the heavy mechanical visual positioning system with a lightweight magnetic field-based positioning system. Instead of using cameras, visual elements, and high-performance processing modules, the system uses a magnetic device to guide and position the UAV, achieving precise landing with significantly reduced weight.
Solution Approach 2:
The patent changes the fundamental parameter of positioning from optical/visual detection to magnetic field detection. This parameter change allows the system to achieve precise position determination using a magnetic device that is much lighter than the required visual elements and processing modules, thus improving the UAV's mounting ability.
3Measurement precision
If down-viewing positioning approach with high precision visual element and high performance processing module is used, then landing position can be determined, but device complexity increases
Solution Approach 1:
The patent replaces the complex visual positioning system requiring cameras, visual elements, and high-performance processing modules with a simple magnetic field-based system. The magnetic device provides both guidance and positioning functions, significantly reducing device complexity while maintaining or improving positioning accuracy.

AI summary
A system for landing a mobile platform, such as an Unmanned Aerial Vehicle (“UAV”) and methods for making and using the same. The system can land the UAV by applying a magnetic levitation force upon the UAV and adjusting the applied magnetic levitation force. The system can initiate a landing process to a designated docking station and can guide the UAV to an adjacency of the designated docking station. Once the UAV has entered the adjacency, the magnetic levitation forces can take control of the landing process. During the landing process, certain magnetic sensitive devices installed on the UAV and/or on the designated docking station can be protected by turning them off or by shielding them. The system overcomes disadvantages of currently-available landing systems by restricting a size and weight of the landing arrangements, as well as, avoiding potential damage to the UAV and the designated docking station.
