Solution Overview

Problem

Existing golf club head designs do not allow for sufficient flexing in the crown to sole direction, fail to change the peak bending location, and lack the ability to store additional spring energy upon impact with the golf ball, limiting ball speed and performance.

Innovation Solution

Incorporation of a cascading sole and back cavity designs in the golf club head, featuring tiered internal thin sections and a hollow construction with a back cavity, which allows for controlled flexing and increased energy storage, enhancing ball speed and performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional solid construction is used, then structural strength is maintained, but flexing capability in crown to sole direction is limited

Engineering Contradiction:
Improvestructural strengthVSAvoidflexing capability
Core Design Contradiction:
StrengthVSAdaptability or versatility

Solution Approach 1:

The club head is divided into multiple sections with varying thicknesses, creating a segmented structure that allows different regions to flex independently. The tiered internal thin sections create distinct zones that can bend at different rates, enabling controlled flexing while maintaining overall structural integrity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the club head are given different thicknesses and material properties to optimize local performance. The internal thin sections have reduced thickness to promote flexing, while outer regions maintain sufficient thickness for strength. This local variation in quality allows the structure to be both strong and flexible in appropriate locations.

Inventive Principle:
Principle #3Local quality

2Ease of manufacture

If uniform thickness design is used, then manufacturing simplicity is maintained, but energy storage capability is limited

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidenergy storage capability
Core Design Contradiction:
Ease of manufactureVSUse of energy by moving object

Solution Approach 1:

The uniform thickness is segmented into multiple tiers with progressively varying thicknesses. This segmentation allows the structure to store more elastic energy during impact by creating a progressive deformation pattern across the tiers, while still using conventional manufacturing processes to create the stepped structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The design transitions from a two-dimensional uniform thickness to a three-dimensional tiered structure with varying thicknesses in the crown-to-sole direction. This dimensional change enables the structure to exploit elastic deformation more effectively, storing additional spring energy that can be released during ball impact.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Stability of the object's composition

If fixed peak bending location is used, then structural predictability is maintained, but ball speed optimization is limited

Engineering Contradiction:
Improvestructural predictabilityVSAvoidball speed
Core Design Contradiction:
Stability of the object's compositionVSSpeed

Solution Approach 1:

The tiered structure creates a dynamic bending pattern where the peak bending location can shift depending on the impact conditions and force applied. During normal play, the bending remains predictable, but under higher impact forces, the structure can utilize additional tiers for energy storage and release, potentially increasing ball speed while maintaining overall structural predictability.

Inventive Principle:
Principle #15Dynamics
