Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for drones has led to a shortage of space for accommodation, resulting in a higher probability of collisions among multiple drones, necessitating a system that prevents collisions and facilitates safe takeoff, landing, and transportation while allowing wireless charging.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple drones are accommodated in limited space, then space utilization is improved, but collision probability among drones increases
Solution Approach 1:
The patent implements vertical stacking of multiple drones on a single landing stand, with each drone positioned at different heights along extension members. This nesting arrangement in the vertical dimension allows multiple drones to occupy the same horizontal footprint without colliding, directly resolving the contradiction between space utilization and collision prevention
Solution Approach 2:
The system transitions from horizontal drone placement to vertical stacking by introducing the height dimension. Extension members protrude vertically from the landing stand surface, enabling drones to be positioned at different elevations (e.g., first drone at higher position, second drone at lower position), thereby accommodating multiple drones in limited horizontal space while preventing collisions through vertical separation
2Quantity of substance
If drones are stacked vertically on landing stand, then space utilization is improved, but control of takeoff and landing speed becomes necessary to prevent collision
Solution Approach 1:
The patent replaces traditional mechanical speed control mechanisms with electromagnetic braking. Electromagnetic brakes are applied to the extension members to control the descent speed of drones during landing and the upward movement during takeoff. This substitution provides precise, collision-free speed control without complex mechanical linkages, enabling vertical stacking while maintaining simple system architecture
Solution Approach 2:
The system controls takeoff and landing speeds by adjusting electromagnetic brake parameters. By varying the braking force applied to extension members, the system precisely controls the velocity of drones during vertical movement, ensuring safe separation between stacked drones and preventing collisions while accommodating multiple drones on the landing stand
3Adaptability or versatility
If existing drones without through-holes are to be accommodated, then adaptability is improved, but the eddy current generation mechanism cannot be directly applied
Solution Approach 1:
The patent separates the eddy current generation function into a distinct landing module that can be attached to existing drones. This module includes the necessary magnetic components and works with the extension members on the landing stand. By segmenting the system this way, existing drones without through-holes can be accommodated through simple module attachment rather than requiring structural modifications to the drone body
Solution Approach 2:
The landing module acts as an intermediary between existing drones and the electromagnetic braking/eddy current system. This module interfaces with the extension members on the landing stand and provides the necessary magnetic interaction surface, enabling eddy current generation and speed control for drones that originally lacked through-holes or magnetic interaction features
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents collisions among drones, allows safe stacking and transportation, adjusts takeoff and landing speeds, and enables wireless charging, even when power is blocked, without affecting existing drone designs.
Implementation Method 1
When the extension member of the landing stand passes through the through-hole of the drone, an eddy current may be generated between the through-hole and the extension member, and magnetic braking may occur in the drone
Implementation Method 2
A first electromagnet is disposed in the through-hole, and a second electromagnet is disposed in the extension member. A magnetic field of the first electromagnet and the second electromagnet is controlled to control a takeoff or landing speed of the drone
Implementation Method 3
A magnetic field of the first electromagnet and the second electromagnet is controlled to control a takeoff or landing speed of the drone or wirelessly charge the drone
