Solution Overview

Problem

Current subsea wet-mate connectors require separate units for power and communications applications, leading to increased space requirements and inefficiencies due to the need for multiple connectors with different ratings and sizes, which complicates underwater manipulation and maintenance.

Innovation Solution

A configurable subsea wet-mate connector design that allows for interchangeable inserts such as power, data, optical fiber, pneumatic, and fluid units within a standard connector body, enabling customization for specific applications while maintaining a unified shape and size, and incorporating adaptable shielding to prevent interference.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate connectors are provided for power and communications applications, then each connector can be optimized for its specific function, but the space required increases and multiple connectors complicate underwater manipulation

Engineering Contradiction:
Improvefunctional optimizationVSAvoidspace requirement
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent combines multiple separate connectors (power connector and communications connector) into a single integrated subsea connector unit. The power connector portion and communications connector portion are merged into one physical connector that can be mated and de-mated as a single unit, reducing the number of separate connectors from two to one while maintaining all necessary functions.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated subsea connector is designed to perform multiple functions simultaneously - it provides both power transmission and communications capabilities in a single connector unit. The connector body incorporates both power conductor pins and communications conductor pins, allowing one connector to serve multiple purposes that previously required separate connectors.

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

2Adaptability or versatility

If separate connectors are provided for power and communications applications, then each connector can be optimized for its specific function, but the device complexity increases

Engineering Contradiction:
Improvefunctional optimizationVSAvoidconnector configuration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple separate connectors (power connector and communications connector) into a single integrated subsea connector unit. The power connector portion and communications connector portion are merged into one physical connector that can be mated and de-mated as a single unit, reducing the number of separate connectors from two to one while maintaining all necessary functions.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If each connector has sufficient room for ROV or diver manipulation, then wet-mate operation is enabled, but the connector size increases

Engineering Contradiction:
Improveunderwater manipulationVSAvoidconnector size
Core Design Contradiction:
Ease of operationVSVolume of moving object

Solution Approach 1:

The integrated subsea connector is designed to perform multiple functions simultaneously - it provides both power transmission and communications capabilities in a single connector unit. The connector body incorporates both power conductor pins and communications conductor pins, allowing one connector to serve multiple purposes that previously required separate connectors.
