UAV Waterproof Container Dual Door Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
A large float is required to transport large packages, but a container cannot function as a float unless it is completely sealed, and maintaining waterproofness requires a completely closed door, posing a challenge in achieving hermetic sealing.
Innovation Solution
An unmanned aerial vehicle equipped with a waterproof container featuring a waterproof door that opens outward, an elastic seal for liquid-tight closure, and a dual door-closing mechanism to enhance hermetic sealing by resisting external forces, ensuring the container remains sealed even when pushed by external forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a large float is used to transport large packages, then the cargo capacity is improved, but the weight and volume of the UAV increase
Solution Approach 1:
The container serves dual functions: as a cargo container for transporting packages and as a float for water landing buoyancy. By integrating the float function into the container structure itself, the patent eliminates the need for separate float components, thereby increasing cargo capacity while minimizing additional weight and volume
2Weight of moving object
If a container is used as a float, then the weight and volume are reduced, but hermetic sealing becomes difficult to achieve
Solution Approach 1:
The door sealing system is divided into multiple independent components: the waterproof door itself, an elastic seal member, and a door-closing mechanism. This segmentation allows each component to be optimized independently - the elastic seal provides continuous contact pressure for hermetic sealing, while the door-closing mechanism ensures proper positioning and engagement
Solution Approach 2:
The elastic seal member changes its physical parameters (deformation, contact pressure) in response to external forces such as water pressure during landing. This parameter change allows the seal to maintain hermetic sealing under varying operational conditions without requiring a completely rigid and complex sealing structure
3Reliability
If a waterproof door is completely closed to maintain waterproofness, then the waterproof reliability is improved, but the ease of operation for opening and closing decreases
Solution Approach 1:
The door-closing mechanism automatically engages and secures the waterproof door in the closed position without requiring manual intervention to maintain sealing. The mechanism self-activates when the door is closed, providing reliable waterproofing while minimizing the operational steps required from the user
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
The solution secures hermetic sealing of the waterproof container, allowing it to function as a float while maintaining the integrity of the package during transport, enhancing the UAV's capability to carry large packages over water.
Implementation Method 1
an elastic seal, which is interposed between the container main body and the waterproof door, and is configured to close the waterproof door in a liquid-tight manner

AI summary
Provided is an unmanned aerial vehicle including a waterproof container (50) including: a container main body (52) having an opening (56) in a bottom surface defined in a landed state of the unmanned surface aerial vehicle; a waterproof door (58) mounted to the container main body (52) so as to open outward and close the opening (56); an elastic seal (70), which is interposed between the container main body (52) and the waterproof door (58), and is configured to close the waterproof door (58) in a liquid-tight manner; a first door-closing mechanism (92) configured to retain a first door-closing state of the waterproof door (58) ; and a second door-closing mechanism (94) configured to prevent movement of the waterproof door (58) in a door-opening direction in a second door-closing state in which the waterproof door (58) has been pushed in a direction of resisting against an elastic force of the elastic seal (70) from the first door-closing state.
