Inflatable Surfboard Bottom Structure for Straightness and Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional inflatable surfboards lack straightness and stability, leading to difficulty in maintaining balance and resistance to external forces, and are not suitable for use in various water-based leisure activities.
Innovation Solution
Incorporating a concave or convex straight part on the lower surface of the surfboard, along with an angle adjuster and a pin box, to enhance straightness and stability, and using drop-stitch fabric with shape maintenance lines to maintain the board's shape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a flat lower surface is used in conventional inflatable surfboards, then manufacturing is simpler, but straightness and stability are insufficient
Solution Approach 1:
The lower surface is segmented into multiple regions: a flat rear portion and a straight part with concave/convex sections. This segmentation allows the board to maintain simplicity in the stable rear area while introducing structural features only where needed for straightness and stability in the front portion.
Solution Approach 2:
The straight part is formed with localized concave or convex sections only in specific areas of the lower surface, rather than making the entire surface complex. This local quality change provides the necessary straightness and stability without requiring overall structural complexity.
2Ease of operation
If a flat lower surface is used, then manufacturing is easier, but balance maintenance becomes difficult
Solution Approach 1:
The lower surface is divided into a flat rear portion for simplicity and a straight part with concave/convex features for balance control. This segmentation allows easier manufacturing in the majority area while providing balance-maintaining features only where hydrodynamic forces require them.
Solution Approach 2:
Concave or convex sections are introduced locally in the straight part of the lower surface to provide balance stability, while the rest of the surface remains flat for manufacturing simplicity. This localized modification improves balance maintenance without requiring complex overall structure.
3Weight of moving object
If conventional materials are used, then manufacturing is straightforward, but weight reduction is limited
Solution Approach 1:
The surfboard employs composite construction combining drop-stitch fabric with air chambers, creating a lightweight yet strong structure. This composite approach significantly reduces weight compared to solid materials while maintaining manufacturing feasibility through established inflatable structure techniques.

AI summary
The present invention relates to an inflatable surfboard having a concave or convex straight part formed on the lower surface thereof, so as to improve the straightness of the board and more simply and stably maintain balance. The present surfboard comprises: a main body (10) formed in a long plate shape by cutting a drop-stitch fabric; a side tape (20) attached along the open circumference of the main body (10) so as to seal same; a straight part (30) convexly or concavely formed in the longitudinal direction on the lower surface of the main body (10); a top reinforcing tape (40) attached to the upper surface of the main body (10); and a bottom reinforcing tape (50) attached to the lower surface of the main body (10).
