Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If atmospheric pressure storage spaces and airlock systems are used for drone deployment from underwater vehicles, then the drone can be deployed, but the system becomes complex and difficult to deploy discreetly

Engineering Contradiction:
Improvedrone deployment capabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the atmospheric pressure storage space and airlock system from the deployment mechanism, replacing them with a simple capsule that is filled with water and uses buoyancy for deployment. This eliminates the complex atmospheric pressure maintenance requirements while achieving reliable drone deployment from underwater vehicles.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent changes the pressure parameter from atmospheric pressure to water pressure by filling the capsule with surrounding water. This parameter change eliminates the need for atmospheric pressure storage spaces and airlock systems, significantly simplifying the deployment mechanism while maintaining reliability.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If atmospheric pressure storage spaces and airlock systems are used for drone deployment, then the drone can be deployed, but the deployment process becomes inefficient

Engineering Contradiction:

AI summary

The drone release system comprises: - a plurality of capsules (6), each capsule (6) containing a drone and being configured to rise to the surface of the water due to its buoyancy of the capsule (6) and to open once the capsule (6) has reached the surface of the water to release the drone, - a store (8) for storing the capsules (6), the store (8) being in permanent fluidic communication with the outside so that the surrounding water fills the store (8) when the underwater craft (2) is submerged, and - a retaining device (16) having a retaining configuration in which the retaining device (16) retains the capsules (6) in the store (8) and a release configuration in which the retaining device (16) releases a capsule (6) for its ascent to the surface of the water.
