Inflatable Product V-Shaped Bottom Protrusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inflatable products with independent inflatable keels require additional inflation steps, have poor water dividing effects due to arc surfaces, and need increased dimensions for stability, which hinders running speed and handling performance.
Innovation Solution
An inflatable product design featuring a bottom sheet and connection sheet forming a containing chamber with a support component that creates a protrusion at the bottom, eliminating the need for separate inflation of the keel and enhancing water dividing and direction control by forming a V-shaped structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If an independent inflatable keel is used as a water dividing structure, then the inflatable product can maintain stability, but it requires additional inflation steps and increases device complexity
Solution Approach 1:
The patent merges the keel structure with the bottom sheet by integrating the water dividing structure directly into the bottom sheet material, eliminating the need for a separate inflatable keel component. This integration maintains stability while reducing device complexity and the number of inflation steps required.
Solution Approach 2:
The bottom sheet is designed to serve multiple functions: it provides the base structure of the inflatable product, maintains stability through its rigidifying portions, and creates water dividing structures. This multi-functionality eliminates the need for dedicated keel components while preserving stability.
2Strength
If an independent inflatable keel is used, then the structure can provide support, but the arc surface provides poor water dividing effect and hinders running speed
Solution Approach 1:
The patent applies local quality by creating rigidifying portions with specific geometric shapes (such as V-shapes or U-shapes) at predetermined positions on the bottom sheet. These localized structures provide necessary support while creating effective water dividing surfaces that improve running speed, rather than using a uniform arc surface.
3Stability of the object's composition
If an inflatable keel is added to improve stability, then the inflatable product gains better stability, but the dimensions need to be increased
Solution Approach 1:
By merging the stability-providing function into the bottom sheet through rigidifying portions, the patent achieves improved stability without adding the volume of a separate keel structure. The stability function is integrated into the existing bottom sheet geometry, avoiding dimensional increases.
4Object-affected harmful factors
If an independent inflatable keel is used, then the water dividing structure can be provided, but it requires separate inflation operation
Solution Approach 1:
The patent combines the water dividing structure with the bottom sheet, so that when the bottom sheet is inflated, the water dividing structures are automatically inflated as well. This integration eliminates the need for separate inflation operations while maintaining effective water dividing capabilities.

AI summary
An inflatable product is provided including: an inflatable body comprising a bottom sheet extending in a longitudinal direction; a connection sheet connected to the bottom sheet, such that a containing chamber is formed between the connection sheet and the bottom sheet; and a support component disposed within the containing chamber. A protrusion protrudes outwards at a bottom of the inflatable body and is formed by the support component within the containing chamber.
