Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drone operation technologies face challenges in achieving advanced autonomous flight capabilities without significantly increasing the drone's performance or development costs, particularly in non-visual flight scenarios where obstacle avoidance and route adherence are critical.
Innovation Solution
A system comprising a drone-side information processing device mounted on the drone, connected via an external device, which acquires and processes control information from a server device to autonomously control the drone's flight, utilizing high-performance processing and communication functions to enhance performance without enhancing the drone itself.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If advanced autonomous flight capabilities are implemented in the drone itself, then obstacle avoidance and route adherence performance are improved, but development costs and device complexity increase significantly
Solution Approach 1:
The patent introduces an external device as an intermediary between the drone and the control system. This external device hosts the information processing device that performs autonomous flight calculations, obstacle detection, and route planning. The drone itself only needs basic flight control capabilities, while the complex autonomous functions are offloaded to the external device connected via communication interface, thereby resolving the contradiction between autonomous capability and device complexity.
2Productivity
If high-performance processing units are integrated into the drone, then autonomous navigation and obstacle avoidance are enhanced, but manufacturing costs increase
Solution Approach 1:
The patent extracts the high-performance information processing functions from the drone and places them in an external device. The drone retains only essential flight control hardware, while the sophisticated processing required for autonomous navigation, obstacle avoidance, and route adherence is performed externally. This extraction principle allows the drone to be manufactured at lower cost while still achieving high autonomous operation efficiency through the connected external processing system.
3Reliability
If the drone is equipped with advanced sensors and processors for non-visual flight, then autonomous flight performance is improved, but the overall system cost increases
Solution Approach 1:
The external device serves as a mediator that provides advanced sensing and processing capabilities without requiring the drone itself to be equipped with expensive sensors and processors. The information processing device in the external system performs obstacle detection, environmental mapping, and autonomous navigation calculations, enabling reliable non-visual flight while minimizing the hardware requirements and cost of the drone platform.
