Solution Overview

Problem

Existing life-preserving devices, such as ring-shaped life belts and inflatable jackets, are limited in their ability to support multiple individuals simultaneously and require time to deploy, occupy significant space, and are cumbersome to store, often failing to provide immediate buoyancy support in emergency situations.

Innovation Solution

An extensible inflatable life-preserving device with a tubular structure made of expandable material, equipped with an automatic inflation mechanism using a salt tablet or manual activation, which expands to support multiple people, featuring stabilizing wings and a compact storage design, allowing rapid deployment and increased visibility with reflector strips and a satellite indicator.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional life-preserving devices (ring-shaped life belts, inflatable jackets) are used, then they can support one person floating in water, but they occupy significant space and are cumbersome to store

Engineering Contradiction:
Improvefloating support capabilityVSAvoidstorage space
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The life-preserving device is designed to be stored in a compact rolled configuration within a container, similar to a nested structure. The tubular structure can be collapsed and stored in a small volume, then rapidly deployed to provide full floating support when needed, resolving the contradiction between storage compactness and functional capability.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The device transitions from a static compact storage state to a dynamic expanded functional state. The tubular structure is designed to be extensible, allowing it to rapidly expand from a small stored configuration to a large floating configuration, enabling both compact storage and reliable floating support.

Inventive Principle:
Principle #15Dynamics

2Reliability

If traditional life-preserving devices are deployed, then they can provide buoyancy support, but they require significant deployment time and are not immediately available in emergencies

Engineering Contradiction:
Improvebuoyancy supportVSAvoiddeployment time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The device is pre-positioned in a ready-to-deploy state within easy reach on the vessel. The compact stored configuration allows rapid retrieval and deployment, eliminating the time loss associated with searching for or assembling traditional life-preserving devices during emergencies.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The device enables rapid deployment by skipping the traditional multi-step inflation and donning process. The extensible tubular structure can be quickly deployed and inflated to provide immediate buoyancy support, rushing through the deployment process to minimize response time.

Inventive Principle:
Principle #21Skipping (Rushing through)

3Adaptability or versatility

If multiple traditional life-preserving devices are stored to rescue multiple people, then sufficient rescue capacity is available, but the devices become even more cumbersome and occupy more space

Engineering Contradiction:
Improvemulti-person rescue capacityVSAvoidstorage space
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The device is designed as a universal life-preserving system that can accommodate multiple users. The extensible tubular structure can be adjusted in length and configured to support one or multiple persons simultaneously, providing multi-person rescue capacity in a single compact unit rather than requiring multiple separate devices.

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

Solution Approach 2:

The tubular structure can be divided into multiple sections or compartments that can be independently inflated or configured. This segmentation allows the device to be adapted for different rescue scenarios, from single-person to multi-person rescue, while maintaining a compact stored configuration.

Inventive Principle:
Principle #1Segmentation

4Reliability

If shipwrecked persons must wear traditional life jackets, then proper buoyancy support is provided, but it is difficult for injured or unconscious persons to put them on

Engineering Contradiction:
Improvebuoyancy supportVSAvoidease of donning
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The device is designed to be easily donned by the user themselves or by rescuers with minimal effort. The openable configuration and extensible structure allow for quick placement on the user, and the device can be adjusted to fit different body sizes, making it accessible even for injured or unconscious persons who cannot perform complex donning procedures.

Inventive Principle:
Principle #25Self-service
