Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a closed receptacle is used for underwater movement, then passengers can be protected from water, but the device becomes complex and costly with watertight walls and air supply infrastructure

Engineering Contradiction:
Improvepassenger protection from waterVSAvoidcomplexity of watertight structure and air supply infrastructure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The device is divided into two functional parts: an emerged support structure and a submerged platform. The support remains above water and does not require watertight sealing, while only the platform needs to be water-resistant for passenger protection. This segmentation eliminates the need for complex watertight walls and air supply infrastructure throughout the entire vehicle.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The air supply infrastructure is extracted from the submerged portion and relocated to the emerged support structure. Breathing air is supplied through flexible hoses connected to the support that remains above water, eliminating the need for complex underwater air supply systems and watertight sealing.

Inventive Principle:
Principle #2Taking out (Extraction)

2Adaptability or versatility

If a closed hull is submerged for underwater experience, then passengers can dive, but the device requires complex infrastructure for air supply and sealing

Engineering Contradiction:
Improveunderwater experience capabilityVSAvoidcomplexity of air supply and sealing infrastructure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device separates the emerged support from the submerged platform, allowing the platform to be simple and water-resistant rather than fully watertight. The support structure handles all complex infrastructure requirements while remaining above water.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Flexible hoses act as intermediaries to supply breathing air from the emerged support to the submerged platform. This eliminates the need for complex underwater air supply infrastructure while maintaining the ability to provide underwater experience.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If the support is fully submerged, then passengers can be underwater, but breathing becomes difficult without complex air supply systems

Engineering Contradiction:
Improvesubmerged position capabilityVSAvoidease of breathing while submerged
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

Flexible hoses serve as intermediaries to deliver breathing air from the emerged support to the submerged platform. This simple intermediary system makes breathing easy while submerged without requiring complex air supply infrastructure.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The breathing air supply is extracted from the submerged environment and relocated to the emerged support structure, simplifying the breathing system while maintaining submerged capability.

Inventive Principle:
Principle #2Taking out (Extraction)

4Adaptability or versatility

If the device is designed for specific diving depths, then underwater exploration is enabled, but transportation to sites and infrastructure costs increase

Engineering Contradiction:
Improvediving site exploration capabilityVSAvoidcost of infrastructure and transportation
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The device separates the transport function (emerged support) from the exploration function (submerged platform). The support can be transported by conventional means and does not require specialized underwater infrastructure, while the platform provides the diving capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The emerged support serves multiple functions: it provides structural support, houses the propulsion system, supplies breathing air, and remains above water during transportation. This multi-functionality reduces the need for specialized infrastructure and transportation costs.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The invention relates to a water vehicle moving on or in a liquid and including a flotation means (1) that is connected by a connection means (6) to a carrier (3), said water vehicle being characterized in that said connection means (6) is shaped so as to enable said carrier (3) to assume at least two positions, namely: - a raised position where the longitudinal axis of said carrier (3) and those of the flotation means (1) substantially extend into the same horizontal plane, the carrier (3) then being on the surface and capable of making up a central shell; and - a lowered position where said carrier (3) extends under the plane comprising the longitudinal axis of each of the flotation means (1), the carrier (3) then being submerged.
