Drone Landing Guide Structure for Precise Wireless Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drone stations face inefficiencies in charging due to misalignment of the drone's center of resonance with the charging station, leading to reduced charging efficiency and increased charging time, and are prone to external environmental factors like wind and vibration causing the drone to crash or become dislodged.
Innovation Solution
The drone station incorporates a landing guidance instrument with an inclined surface and a guide member to align and secure the drone over a wireless charging instrument, featuring a power transmission coil and a guide member to ensure optimal charging alignment and stability, along with a protective cover for safe landing and takeoff.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the drone is landed at the drone station using only GPS information, then the landing process is simple, but the center of resonance between the drone station and the drone is not accurately aligned, reducing charging efficiency and increasing charging time
Solution Approach 1:
The patent introduces an inclined surface as an intermediary mechanical structure between the landing platform and the charging position. This inclined surface acts as a mediator that automatically guides the drone from its GPS-guided landing position to the precise charging position, resolving the contradiction between simple GPS-based landing and precise alignment requirements.
Solution Approach 2:
The patent replaces complex active mechanical adjustment systems with a passive inclined surface structure. Instead of using motors, sensors, or active control mechanisms to align the drone, the design uses a fixed inclined surface that passively guides the drone through gravitational force and geometric constraint, simplifying the system while achieving precise alignment.
2Duration of action of moving object
If the drone is charged at the drone station, then the drone can be recharged, but the drone is out of the charging position or crashes at the drone station due to external environmental factors such as wind and vibration
Solution Approach 1:
The patent incorporates a guide member positioned beforehand at the charging location to provide pre-positioning and stabilization. This guide member acts as a cushioning mechanism that prevents the drone from deviating from the charging position due to external disturbances like wind and vibration, ensuring reliable charging.
Solution Approach 2:
The guide member structure creates a confined spatial envelope that flexibly accommodates the drone while maintaining positional stability. The geometric constraints formed by the guide member provide a stable charging environment that resists external environmental factors.
3Manufacturing precision
If an inclined surface is added to move the drone to the charging position, then alignment accuracy is improved, but the device complexity increases
Solution Approach 1:
The patent divides the landing and charging functions into distinct spatial zones: a landing platform area and a charging position area connected by an inclined surface. This segmentation allows each component to perform its specific function independently, achieving precise alignment without requiring complex integrated systems.
Solution Approach 2:
The inclined surface introduces a geometric curvature element that simplifies the transition from landing to charging position. By using a simple inclined plane rather than complex mechanical adjustments, the patent achieves precise alignment through geometric design, reducing overall system complexity.
