Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing amphibious UAVs face challenges in withstanding high impact ground landings and operating on both water and rugged terrain while protecting electrical and electronic components, which are often reliant on maintaining the integrity of the fuselage.
Innovation Solution
The design features modularized compartments with buoyant walls and weep holes, allowing the UAV to land on water and rugged terrain without relying on the fuselage's integrity for component protection, with components hermetically sealed and shock-absorbing materials used to minimize impact damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the fuselage integrity is maintained to protect electrical and electronic components, then component protection is improved, but the UAV cannot withstand high impact ground landings and rugged terrain operation
Solution Approach 1:
The fuselage is divided into multiple sealed compartments (battery compartment, payload compartment, electronics compartment) that can be independently protected. This segmentation allows the overall structure to be less rigid while maintaining local protection for critical components, enabling the UAV to withstand high impact landings and rugged terrain operation without compromising component integrity.
2Reliability
If the fuselage is sealed to protect components from water, then water protection is improved, but the UAV cannot drain water after water landings
Solution Approach 1:
Fluid drain ports are pre-positioned at the lowest point of each fuselage compartment before the UAV operates. These ports remain closed during normal operation but automatically open to drain water after water landings, preventing water accumulation and maintaining component protection without requiring the entire fuselage to be unsealed.
3Weight of moving object
If the fuselage is made lightweight to reduce overall weight, then weight is reduced, but the structural integrity for component protection is compromised
Solution Approach 1:
Instead of making the entire fuselage heavy for uniform protection, the invention applies localized quality enhancement by creating hermetically sealed compartments only around critical electrical and electronic components. The remaining fuselage structure can be lightweight, achieving overall weight reduction while maintaining component protection through targeted sealing at compartment levels.
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
This design enables the UAV to safely land on various surfaces while minimizing weight and complexity by allowing water drainage and using modular compartments to absorb impacts, ensuring component protection without compromising the fuselage's integrity.
Implementation Method 1
The walls 110 of the fuselage 100 are composed of a buoyant material so that the fuselage 100 will float without wings (not shown) attached when the fuselage is fully loaded with components
Implementation Method 2
Drainage openings such as weep holes 128b in the channel 126f extend through the bottom wall 110b of the fuselage 100

AI summary
An amphibious unmanned aerial vehicle is provided, which includes a fuselage (100) comprised of a buoyant material. Separators (150, 160) within the fuselage (100) form separate compartments within the fuselage. Mounts associated with the compartments for securing waterproof aircraft components within the fuselage. The compartments (120, 130, 140) each have drainage openings in the fuselage extending from the interior of the fuselage to the exterior of the fuselage.
