Modular UUV Architecture with Magnetic Attachments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing unmanned underwater vehicles (UUVs) and autonomous vehicles are highly specialized, leading to high production costs due to nonrecurring engineering expenses and limited market appeal, with fixed designs that cannot be modified in the field, resulting in restricted mission flexibility and increased operator costs.
Innovation Solution
A modular design for UUVs and autonomous vehicles that allows users to assemble and configure modules such as command and control, propulsion, sensors, and buoyancy control, enabling customization for specific missions without the need for new vehicles, with magnetic attachments for secure and maintenance-free connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If specialized fixed designs are used for UUVs, then vehicle performance for specific missions is optimized, but production costs increase and mission flexibility is reduced
Solution Approach 1:
The UUV is divided into separate functional modules (propulsion module, payload module, control module, etc.) that can be independently designed, manufactured, and reconfigured. This segmentation allows each module to be optimized for its specific function while enabling flexible reassembly for different mission requirements, thus maintaining vehicle performance while improving mission flexibility.
Solution Approach 2:
The vehicle configuration is made dynamic through the ability to reassemble and reconfigure modules in the field. Rather than a fixed design, the UUV can be dynamically adapted to different missions by changing module combinations and arrangements, resolving the contradiction between optimized performance and flexibility.
2Reliability
If specialized fixed designs are used for UUVs, then specific mission requirements are met, but production and acquisition costs increase
Solution Approach 1:
The modular architecture creates universal components that can serve multiple mission types. A single propulsion module or control module can be used across different UUV configurations, reducing the number of unique parts that need to be manufactured and reducing production costs while maintaining mission capability.
Solution Approach 2:
The modular design enables individual modules to be discarded, replaced, or recovered independently. If a module fails or needs upgrading, only that specific module is affected, not the entire vehicle. This reduces manufacturing costs by allowing selective replacement rather than complete vehicle replacement.
3Ease of manufacture
If fixed vehicle designs are used, then manufacturing is simplified, but field modifications and repairs become impossible
Solution Approach 1:
By segmenting the vehicle into modular components with standardized interfaces, the design maintains manufacturing simplicity through repeatable assembly processes while enabling field repairs. Damaged modules can be independently replaced without affecting the rest of the vehicle, resolving the contradiction between manufacturing simplicity and field repairability.
4Reliability
If multiple specialized vehicles are purchased for different missions, then each vehicle is optimized for its specific mission, but operator costs and fleet management complexity increase
Solution Approach 1:
A single fleet of modular UUVs can perform multiple mission types by reconfiguring the same base vehicles with different module combinations. This eliminates the need for separate specialized vehicles for each mission, reducing fleet management complexity and operator costs while maintaining mission optimization through appropriate module selection.

AI summary
In a configurable vehicle a variety of mechanisms connect an external heat sink to an interior volume of the vehicle without creating a fluid conduit between the exterior and interior volume of the vehicle. Reliability of the vehicle is improved since exterior elements cannot penetrate to the interior of the vehicle.
