Solution Overview

Problem

Existing footwear cleat systems lack a secure and adjustable mechanism for rotating cleat members to optimize traction and speed in various athletic activities, as they often rely on fixed or cumbersome attachment methods that do not allow for easy adjustment of cleat orientation.

Innovation Solution

A footwear design featuring a radial locking system with radially disposed locking elements on both the cleat receiving portion and the removable cleat member, allowing for secure attachment and adjustable angular positioning of cleat members using a fastener that inserts through cavities in both components, preventing rotation and enabling various traction configurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed attachment method is used for cleat members, then the structure is simple, but the adaptability for different athletic activities is poor

Engineering Contradiction:
Improveadaptability for different athletic activitiesVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cleat member is divided into separate components: a body portion with cavities and a base portion with locking elements. This segmentation allows the cleat to be rotated and repositioned within the sole structure while maintaining structural integrity, enabling adaptability for different athletic activities without excessive complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cleat member is designed with rotational freedom around a central axis, allowing it to dynamically adjust between fixed and rotatable states. The radial locking elements enable the cleat to be secured at different angular positions, providing versatility for various athletic movements while maintaining a relatively simple overall structure

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If a removable cleat member is used, then the adaptability is improved, but the reliability of attachment is reduced

Engineering Contradiction:
Improveadjustability of cleat orientationVSAvoidattachment security
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The locking mechanism utilizes radial locking elements that engage in a circular pattern around the central axis of the cleat member. This radial arrangement provides uniform distribution of locking forces, ensuring secure attachment while allowing rotational adjustment to different angular positions for optimized traction in various directions

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The fastener system combines multiple functions into a single mechanism: it secures the cleat member to the sole structure, prevents rotation during use, and maintains the cleat at the desired angular position. This integration of functions ensures reliable attachment while preserving adjustability

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If a radial locking system is implemented, then the prevention of rotation is improved, but the device complexity increases

Engineering Contradiction:
Improveprevention of cleat rotationVSAvoidlocking system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The radial locking elements are positioned asymmetrically around the central axis of the cleat member, with specific angular spacing between elements. This asymmetric arrangement provides effective rotation prevention at discrete angular positions while keeping the locking mechanism relatively simple, avoiding the need for continuous rotation control

Inventive Principle:
Principle #4Asymmetry

AI summary

An article of footwear (100) includes a cleat system (200) with removable cleat members (202). The removable cleat members are fastened onto cleat receiving portions (204) of a sole structure (110) using fasteners (206). The removable cleat members can be placed at various angular positions and fastened in place to maintain the angular positions. The removable cleat members can be asymmetric to allow for different operating configurations of the cleat system.
