Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a traditional landing pad without magnetic attraction is used, then the structure is simple, but the drone experiences unstable sliding during landing
Solution Approach 1:
The patent replaces traditional mechanical friction-based landing pad surfaces with a magnetic field-based attraction system. The magnetic landing pad uses electromagnetic or permanent magnets to generate magnetic force that attracts and stabilizes the drone during landing, eliminating the need for complex mechanical friction surfaces while providing stable landing without sliding.
Solution Approach 2:
The patent changes the physical parameter of the landing pad surface from non-magnetic to magnetic properties. By introducing magnetic field strength as a controllable parameter, the system can adjust the magnetic attraction force to match the drone's weight and landing dynamics, providing stable landing while keeping the structural design relatively simple.
2Stability of the object's composition
If a magnetic landing area is used to prevent sliding, then landing stability is improved, but the drone cannot take off from the same area
Solution Approach 1:
The patent divides the landing pad into two distinct functional zones: a magnetic landing area for stable landing and a non-magnetic takeoff area for clean takeoff. This segmentation allows each zone to optimize its specific function without compromising the other, enabling the drone to land stably on the magnetic area and take off cleanly from the non-magnetic area.
Solution Approach 2:
The patent applies different magnetic properties to different locations on the landing pad. The landing area has strong magnetic attraction for stable landing, while the takeoff area has no or reduced magnetic attraction to allow clean takeoff. This local differentiation of magnetic properties enables both landing stability and takeoff capability to coexist in the same system.
3Stability of the object's composition
If aggressive maneuvering is used during landing, then the drone can overcome instability, but energy consumption increases and potential damage occurs
Solution Approach 1:
The patent implements a magnetic field that gradually increases in strength as the drone approaches the landing pad, providing progressive stabilization. This beforehand magnetic cushioning reduces the need for aggressive corrective maneuvers by continuously guiding and stabilizing the drone during its final approach, thereby reducing energy consumption and preventing damage from harsh corrections.
