Swim Cap Scale Tile Array for Drag Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional swim caps lack innovative exterior surface designs that reduce dynamic viscous flow drag, hindering swimming efficiency in competitive swimming.
Innovation Solution
The swim cap features a unique scale tile array with riblets on its exterior surface, allowing bi-directional fluid flow and minimizing drag by incorporating individual scale tiles with specific geometric patterns and dimensions, maintaining the cap's shape and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a smooth outer exterior surface is used on the swim cap, then the basic shape and simplicity are maintained, but dynamic viscous flow drag is not reduced
Solution Approach 1:
The patent applies riblet patterns only to specific regions of the swim cap exterior surface, particularly in areas where fluid flow occurs, while maintaining a smooth overall cap structure. This localized application reduces drag in critical flow zones without complicating the entire cap design or manufacturing process.
Solution Approach 2:
The riblet patterns consist of curved, rounded structures rather than sharp edges or flat surfaces. These curved riblet elements follow the contour of the swim cap and guide fluid flow smoothly, reducing turbulence and drag while maintaining compatibility with the cap's spherical head form.
2Productivity
If surface detailing is added to reduce drag, then swimming efficiency is improved, but the basic shape of the swim cap and head may be altered
Solution Approach 1:
The riblet surface detailing is applied locally to the exterior surface of the swim cap rather than changing the overall cap geometry. This allows drag reduction through surface texture while preserving the fundamental shape and fit of the cap on the swimmer's head.
Solution Approach 2:
Instead of modifying the three-dimensional shape of the cap, the patent introduces drag-reducing features in the surface dimension only. The riblets create a textured surface layer that affects fluid flow without altering the cap's external contours or head form.
3Ease of manufacture
If conventional smooth surface design is used, then manufacturing is simple, but drag reduction is not achieved
Solution Approach 1:
The patent modifies the surface parameters of the swim cap by introducing riblet patterns with specific geometric characteristics (height, spacing, angle) that optimize drag reduction. These parameter changes can be implemented through standard manufacturing techniques like molding or coating, maintaining ease of production while achieving hydrodynamic benefits.
