Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multirotor aircraft designs pose safety risks and operational limitations for the camera system during takeoff and landing, and restrict camera angles and accessibility, especially when changing lenses or requiring independent camera control.
Innovation Solution
A multirotor aircraft design featuring a rotating body connected to a frame via a bearing, equipped with actuator assemblies and a drive system that allows the body to rotate 180 degrees, enabling safe camera positioning during takeoff and landing, and providing 360-degree filming capabilities with a shock-absorbing mechanism and controller for automatic camera stabilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the camera system is moved below the level of the landing structure or the landing structure is moved over the level of camera view, then unobstructed 360 degree view is achieved, but the camera is not safe at takeoff or landing and is hard to reach
Solution Approach 1:
The patent applies a rotating body mechanism that allows the camera assembly to dynamically change its position relative to the landing structure. The body can rotate to bring the camera above the landing structure during flight while keeping it protected below during takeoff and landing, thus achieving both safety and viewing flexibility.
2Adaptability or versatility
If the whole flight system has to be rotated, then camera viewing angles are improved, but dynamic control and independence of camera control from flight control is limited
Solution Approach 1:
The patent separates the camera control system from the flight control system by implementing an independent rotating body mechanism. This segmentation allows the camera assembly to be controlled independently through the drive system, enabling camera positioning without requiring rotation of the entire flight system.
3Adaptability or versatility
If the camera is positioned for front viewing, then upward and downward views are enabled, but yaw control of the camera requires rotation of the whole system
Solution Approach 1:
The rotating body mechanism provides dynamic positioning capability for the camera assembly. The drive system can rotate the body to orient the camera in any direction (up, down, left, right, front, back) independently, eliminating the need for whole system rotation to achieve yaw control.
Applied Scientific Principles
