UAV Cam-Actuated Landing Structure for Clear Camera Views
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unmanned Aerial Vehicles (UAVs) face issues with damaged external rotor blades and motors due to collisions or emergency landings, and existing landing members either aesthetically impair the design or interfere with camera shooting, requiring a solution that does not compromise either functionality or appearance.
Innovation Solution
A UAV design incorporating a landing member that serves as part of the housing and selectively protrudes using a cam structure, allowing for safe landing without obstructing camera views or aesthetics, and can be integrated into the vehicle's structure for both closed and open positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed landing member is used to prevent damage during landing, then the housing and rotor blades are protected from ground contact, but the exterior appearance is aesthetically impaired and camera shooting is interrupted
Solution Approach 1:
The landing member is designed to be movable rather than fixed, allowing it to change position between a retracted state (during flight) and an extended state (during landing). The movable landing member includes a support portion that can protrude from the housing to contact the ground, and a cam structure that enables controlled movement between positions, thus protecting the exterior appearance during flight while providing protection during landing.
2Shape
If a foldable landing member structure is used to improve appearance, then the exterior is aesthetically improved, but additional components are required increasing device complexity
Solution Approach 1:
The cam structure serves multiple functions simultaneously: it acts as both the actuating mechanism for moving the landing member and as part of the landing support structure itself. The cam groove formed in the housing and the cam structure on the movable landing member work together as an integrated mechanism, eliminating the need for separate actuators or complex folding structures while still achieving the desired aesthetic appearance.
3Force
If a landing member protrudes from the housing, then the load is supported during landing, but the camera shooting is interrupted and aesthetics are impaired
Solution Approach 1:
The landing member is designed to dynamically change its position based on flight conditions. During normal flight, the support portion is retracted into the housing, maintaining clear camera views and aesthetic appearance. During landing, the cam structure actuates the support portion to protrude outward, enabling load support while minimizing interference with camera operations by controlling the timing and extent of protrusion.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables UAVs to land safely without damaging the exterior and maintains camera functionality, providing a compact and aesthetically pleasing design by using a cam-activated landing member that supports the vehicle's load during landing.
