Solution Overview

Problem

Inflatable devices for gliding on water, such as bodyboards, often lack stability, making them difficult for inexperienced users to control and maintain, especially when short, leading to frequent dismounts and re-mounts.

Innovation Solution

An inflatable device with a flexible first pocket for fluid inflation, featuring stabilization means placed between the legs or secured to the upper part of the legs, and hand positioning means integrated into the pocket, such as handles or deformations, to enhance stability during sliding.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Weight of moving object

If the inflatable device is made short and light for portability, then ease of transport is improved, but stability during gliding deteriorates

Engineering Contradiction:
Improveweight of inflatable deviceVSAvoidstability during gliding
Core Design Contradiction:
Weight of moving objectVSStability of the object's composition

Solution Approach 1:

The inflatable device is divided into multiple independent air chambers (first chamber, second chamber, third chamber) that can be inflated separately. This segmentation allows the device to maintain a compact, lightweight form when deflated for transport, while providing distributed buoyancy and structural stability when inflated during use. The multiple chambers work together to prevent the device from tipping or becoming unstable during gliding.

Inventive Principle:
Principle #1Segmentation

2Length of moving object

If the inflatable device is made short for portability, then ease of transport is improved, but control and stability deteriorate

Engineering Contradiction:
Improvelength of inflatable deviceVSAvoidcontrol during gliding
Core Design Contradiction:
Length of moving objectVSEase of operation

Solution Approach 1:

The inflatable device incorporates lateral extension elements that protrude sideways from the main body, creating a wider footprint without significantly increasing the overall length. This dimensional change provides better lateral stability and control surfaces for steering, allowing short users to maintain effective control during gliding while keeping the device compact for transport.

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

3Device complexity

If the inflatable device lacks attachment means, then device complexity is reduced, but reliability of user attachment deteriorates

Engineering Contradiction:
Improvecomplexity of attachment systemVSAvoidattachment reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The attachment means are integrated directly into the inflatable structure itself, combining the structural function of the inflatable chambers with the attachment function. The inflatable walls and chambers serve dual purposes: providing buoyancy and structural support, while simultaneously forming the attachment points and interfaces for securing the user. This merging eliminates the need for separate, complex attachment mechanisms.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The invention relates to an inflatable device capable of acting as a glide medium for at least one person, which can in particular be used for bodyboard devices for gliding over water or snow. The device includes at least one first bag (1) made of a flexible material, having a means (2) for feeding a fluid therein and capable of being inflated by said fluid, at least one stabilization means (3) connected to the first bag and capable of being arranged between or rigidly connected to the upper portion of the legs of a person, and means (5, 6) for positioning the hands, preferably arranged on the first bag (1). Thus, the proper stabilization of the device beneath the person during a gliding phase is ensured.
