Grained Rubber Surface Structure for Sports Boots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sports boot designs lack individual customization options, leading to suboptimal ball contact and control, especially under varying impact forces, and often result in inaccurate shots due to differing surface materials and structures between the upper part and sole.
Innovation Solution
A grained rubber surface structure is applied to sports boots using an adhesive, allowing for customizable groove and rib patterns based on player preferences, ensuring consistent surface contact and reducing the impact of sole rim interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional sports boot designs are used with fixed surface structures, then manufacturing is simple and cost-effective, but ball contact control and accuracy are suboptimal due to lack of customization
Solution Approach 1:
The upper part is divided into multiple directing zones, each with grooves oriented in different directions (e.g., longitudinal, transverse, diagonal) to provide different ball control functions for different playing styles and impact forces
Solution Approach 2:
The groove patterns are designed to adapt to varying impact forces and kicking angles, with different zone configurations optimized for different playing situations and player preferences
2Strength
If the sole rim is made of hard material for durability, then the boot structure is strong, but ball contact accuracy deteriorates due to inconsistent surface properties between upper and sole
Solution Approach 1:
The grooved surface structure is applied locally to the upper part while the sole rim maintains its hard material properties, creating distinct functional zones where the upper provides ball control and the sole provides structural support
Solution Approach 2:
The grooved surface structure acts as an intermediary layer between the ball and the hard sole rim, ensuring consistent ball contact properties regardless of the sole material hardness
3Duration of action of stationary object
If smooth surfaces are used on ribs and grooves for comfort, then wear resistance is improved, but ball contact friction is reduced leading to slippage
Solution Approach 1:
The grooves and ribs have different surface treatments in different regions: contact areas have higher friction for ball grip, while non-contact areas remain smooth for durability and comfort

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The customizable surface structure enhances ball control and accuracy by providing a consistent contact surface, adaptable to individual playing styles, and extends the boot's lifespan by concealing wear and tear, while allowing for easy reconfiguration.

AI summary
A surface structure for sports boots used for ball games having increased ball-contact properties where each boot has an upper part and a sole and the upper part has an outer surface used for shooting a ball, wherein at least a part of said ball shooting outer surface comprises a coating that has an adhesive substance covering said outer surface and a grained structure embedded in and kept by the adhesive. The grained structure comprises discrete granules of a resilient material, wherein between the adhesive and the outer surface of the upper part and between the adhesive and the granules a stable and durable bonding is provided, and the granules have outer surfaces that provide an improved contact with the ball when getting in contact with it.
