Solution Overview

Problem

Current lifting apparatuses for submarines are limited in integrating multiple atmospheric interface devices of reduced size for independent operation, requiring cumbersome dedicated systems that are difficult to integrate and increase overall dimensions and weight.

Innovation Solution

A lifting apparatus with a single guide element interposed between two movable mounting units, each equipped with independent actuators, allowing for simultaneous or sequential lifting of multiple devices, reducing the overall size and weight by utilizing a shared supporting member and guides integrated within the conning tower.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple atmospheric interface devices are lifted using dedicated lifting apparatuses, then each device can operate independently, but the overall size and weight of the system increases significantly

Engineering Contradiction:
Improveindependent operation of devicesVSAvoidweight of lifting apparatus
Core Design Contradiction:
ReliabilityVSWeight of stationary object

Solution Approach 1:

The patent combines multiple lifting functions into a single shared lifting apparatus. The guide structure supports multiple movable mounting units that can independently position and lift different atmospheric interface devices, eliminating the need for separate dedicated lifting systems for each device while maintaining independent operational capability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The lifting apparatus is designed with universal functionality to handle multiple types of atmospheric interface devices simultaneously. The guide and movable mounting unit configuration allows the same apparatus to service sensors, antennas, periscopes, and other interface devices, making the system multi-functional rather than dedicated to a single device type.

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

2Weight of stationary object

If multiple atmospheric interface devices are integrated on a single lifting apparatus, then size and weight are reduced, but the devices cannot operate independently

Engineering Contradiction:
Improveweight of lifting apparatusVSAvoidindependent operation of devices
Core Design Contradiction:
Weight of stationary objectVSAdaptability or versatility

Solution Approach 1:

The lifting apparatus is segmented into multiple independent movable mounting units, each capable of autonomous positioning and operation. Each mounting unit can independently carry and position atmospheric interface devices along the guide structure, enabling devices to operate independently even when shared infrastructure is used.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system employs dynamic movable mounting units that can independently travel along the guide structure and position devices at different locations and times. This dynamic capability allows multiple devices to be serviced independently by the same lifting apparatus, with each device being able to reach its optimal operating position autonomously.

Inventive Principle:
Principle #15Dynamics

3Reliability

If dedicated lifting apparatuses are used for each sensor or antenna, then independent operation is ensured, but the system becomes complex and difficult to integrate

Engineering Contradiction:
Improveindependent operation of devicesVSAvoidcomplexity of lifting system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Multiple dedicated lifting functions are merged into a single integrated guide structure with multiple movable mounting units. This consolidation reduces the total number of separate lifting apparatuses needed while maintaining the independent operation capability through the modular mounting unit design.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The lifting apparatus is designed as a universal platform that can handle multiple device types through standardized movable mounting units. This universality simplifies integration compared to dedicated apparatuses for each device type, as the same infrastructure serves multiple functions with consistent operational protocols.

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

4Volume of stationary object

If the lifting apparatus is reduced in size for better integration, then space is saved, but the capability to lift multiple devices independently is lost

Engineering Contradiction:
Improvevolume of lifting apparatusVSAvoidcapability to lift multiple devices
Core Design Contradiction:
Volume of stationary objectVSAdaptability or versatility

Solution Approach 1:

The movable mounting units are designed to nest within or along the guide structure, allowing compact storage when not in use. The units can be positioned along the length of the guide, utilizing vertical and horizontal space efficiently, thereby reducing the overall volume footprint while maintaining the capability to service multiple devices.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The system utilizes the vertical dimension of the guide structure to accommodate multiple movable mounting units at different heights. This vertical arrangement allows multiple devices to be lifted and positioned independently within a compact horizontal footprint, effectively trading vertical space for reduced overall volume.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
