Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current golf club driver designs fail to efficiently reduce drag forces, leading to reduced head speed and impaired performance, particularly due to larger geometries and USGA limitations on design parameters, which hinder the club's ability to achieve higher ball velocities and longer shots.
Innovation Solution
The design incorporates specific cross-sectional dimensional relationships between the face, transitional surfaces, and body surfaces, optimizing dimensions such as A, B, C, D, and E to reduce drag coefficients, and utilizes Computational Fluid Dynamics (CFD) analysis to enhance airflow and transition surface shapes, ensuring the club head travels faster with improved aerodynamics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If driver head geometry is increased to improve inertia and face size for off-center hits, then forgiveness and ball speed on off-center hits improve, but drag force increases and head speed decreases
Solution Approach 1:
The patent applies parameter changes by optimizing the drag coefficient through specific geometric parameters of the driver head. The invention defines precise dimensional relationships (A≥0.36 inches, B≥0.3 inches, C≤2.0 inches, D>1.0 inch, E>1.0 inch, and (A+B)/C≥30%) to minimize drag force while maintaining acceptable head geometry for forgiveness. This resolves the contradiction by finding optimal parameter values that balance both forgiveness and drag reduction.
Solution Approach 2:
The patent transitions from considering only two-dimensional face size to incorporating three-dimensional aerodynamic considerations. By adding the dimensional constraints on A, B, C, D, and E that define the aerodynamic profile, the invention addresses drag force (a three-dimensional aerodynamic property) while maintaining the two-dimensional face area requirements for forgiveness. This multi-dimensional approach resolves the contradiction between face size and drag.
2Volume of moving object
If driver head volume and dimensions are increased to improve performance, then inertia and forgiveness improve, but USGA compliance becomes difficult and drag force increases
Solution Approach 1:
The patent uses parameter changes to define specific dimensional relationships that optimize the balance between volume and drag. By constraining C≤2.0 inches while requiring A≥0.36 inches and B≥0.3 inches, the invention maintains adequate volume for inertia while controlling the aerodynamic profile to minimize drag force. The ratio constraint (A+B)/C≥30% ensures proper proportioning.
Solution Approach 2:
The patent moves beyond simple volume maximization to incorporate aerodynamic dimensioning. The additional dimensional parameters (A, B, C, D, E) create a multi-dimensional design space that allows volume optimization while simultaneously controlling drag characteristics, resolving the contradiction between volume and drag force.
3Ease of manufacture
If conventional driver designs are used to maintain simplicity, then manufacturing is easier, but drag force is not reduced and head speed is limited
Solution Approach 1:
The patent applies parameter changes by establishing specific dimensional constraints (A≥0.36 inches, B≥0.3 inches, C≤2.0 inches, D>1.0 inch, E>1.0 inch, and (A+B)/C≥30%) that define an optimized aerodynamic profile. These parameter specifications provide clear manufacturing guidelines while achieving drag reduction, thus maintaining ease of manufacture while improving head speed through reduced drag forces.
