Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing golf shoes do not effectively enhance forward strength and stability during a golf swing, leading to variable shot distances and potential foot slippage.

Innovation Solution

A footwear device with a coupling element and fastening element that rotate relative to each other, featuring protrusions for lateral leverage, and a retention mechanism to control rotation, enhancing stability and leverage during the swing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional spikes are used in golf shoes, then basic traction is provided, but lateral leverage and foot stability during the swing are insufficient

Engineering Contradiction:

Improvelateral leverageVSAvoidfootwear structure

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The footwear device is divided into separate functional components: a coupling element with protrusions for lateral leverage, a fastening element for securing the foot, and a retention means to hold these elements together. This segmentation allows each component to be optimized for its specific function while maintaining overall simplicity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The coupling element is designed to rotate relative to the fastening element about an axis during the golf swing, allowing dynamic adaptation to the forces and motions experienced during the swing while maintaining traction and stability

Inventive Principle:

Principle #15Dynamics

2Stability of the object's composition

If the foot is secured rigidly in the shoe, then stability is improved, but the ability to accommodate natural foot movement during swing is reduced

Engineering Contradiction:

Improvefoot stabilityVSAvoidfoot movement accommodation

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The rotatable connection between the coupling element and fastening element allows the foot to move naturally during the swing while maintaining stability. The rotation axis is positioned to accommodate the natural torsional movement of the foot during a golf swing

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The device changes the degree of freedom from fully rigid to partially rotatable, allowing controlled movement around a specific axis while maintaining stability in other directions. This parameter change enables both stability and adaptability

Inventive Principle:

Principle #35Parameter changes

3Reliability

If protrusions are added to provide lateral leverage, then traction is improved, but the complexity of manufacturing increases

Engineering Contradiction:

ImprovetractionVSAvoidmanufacturing process

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The protrusions are integrated into the coupling element as a single formed component rather than separate attachments. The coupling element, protrusions, and rotation mechanism are designed to be manufactured as one piece or pre-assembled unit, simplifying the manufacturing process

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The coupling element serves multiple functions: it provides the rotational connection, houses the protrusions for lateral leverage, and interfaces with the fastening element. This multi-functionality reduces the total number of components and simplifies manufacturing

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A footwear device comprising protrusions which extend into a surface provide increased leverage when a force is required to be applied in a plane about perpendicular to the protrusions and about parallel to the surface. In particular, footwear devices can increase leverage in a sport requiring increased leverage to essentially maintain contact with the footwear and the ground, such as but not limited to golf.
