Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Lightweight rescue rings lack sufficient structural and tensional integrity to handle larger loads or objects, and their design makes it inconvenient to attach them to various items for retrieval purposes.

Innovation Solution

A throwable rotatable rescue device with a detachable cord and hook system, where the hook is securely mounted in a pocket within the rescue ring to maintain aerodynamics and structural integrity, allowing for easy detachment and reattachment to objects or persons for retrieval.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If the rescue ring is made of lightweight materials to enable long-distance throwing, then the throwing range is improved, but the structural and tensional integrity deteriorates making it insufficient for handling larger loads

Engineering Contradiction:

Improvethrowing rangeVSAvoidstructural and tensional integrity

Core Design Contradiction:

Length of moving objectVSStrength

Solution Approach 1:

The rescue device is divided into separate functional components: a lightweight aerodynamic ring for throwing and a detachable cord assembly with attachment member for load handling. This segmentation allows the ring to be optimized for throwing range while the cord assembly provides the necessary strength for larger loads.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The rescue ring is designed to serve multiple functions: it acts as a throwing vehicle for long-distance delivery, a retrieval tool for pulling objects to safety, and a mounting platform for various attachment members (hooks, eyes, loops) that can handle different types of loads including persons and larger objects.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Strength

If the attachment member is permanently fixed in the rescue ring, then the structural integrity is improved, but the versatility deteriorates making it inconvenient to attach to various objects

Engineering Contradiction:

Improvestructural integrityVSAvoidease of attachment to various objects

Core Design Contradiction:

StrengthVSAdaptability or versatility

Solution Approach 1:

The attachment member is designed with dynamic characteristics - it can be quickly inserted into and removed from the pocket in the rescue ring. This dynamic attachment system allows the user to adapt the rescue device to different objects and situations while maintaining structural integrity when attached.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The pocket acts as an intermediary mechanism between the rescue ring and the attachment member. It provides a standardized interface that maintains the structural integrity of the ring while enabling versatile attachment of different load-bearing components through a simple insertion/removal action.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Stability of the object's composition

If the attachment member is located at the center of the rescue ring, then the structural symmetry is improved, but the aerodynamics deteriorates interfering with the flight path

Engineering Contradiction:

Improvestructural symmetryVSAvoidaerodynamics

Core Design Contradiction:

Stability of the object's compositionVSShape

Solution Approach 1:

The attachment member is positioned in a pocket located at a specific location on the rescue ring rather than at the center. This local positioning allows the attachment function to be separated from the aerodynamic center, maintaining the streamlined shape and flight characteristics of the ring while providing structural support at the needed location.

Inventive Principle:

Principle #3Local quality

AI summary

A throwable rotatable rescue device having a cord wound therein including a cord reel for storing and unwinding the cord therefrom as the rescue device is thrown. One end of the cord is detachably mounted to the rescue device to enable a person receiving a thrown rescue device to reach into an interior region of the rescue device and detach the cord from the rescue device. Thereafter one can attach the cord to an object that can be retrieved by pulling on the cord.
