Golf Club Head Crown Contouring for Lower Aerodynamic Drag
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern golf club heads with large volumes and high moments of inertia suffer from poor aerodynamic performance due to their design, leading to increased aerodynamic drag forces and reduced club head speeds, despite efforts to enhance resistance to twisting during off-center shots.
Innovation Solution
The design incorporates a large projected area of the face portion and a crown section with a significant drop contour area, featuring unique radii of curvature and a post apex attachment promoting region to improve airflow reattachment and reduce aerodynamic drag, resulting in a high volume aerodynamic golf club head with superior aerodynamic properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the club head volume is increased to 460 cc and the front-to-back dimension is extended to increase moment of inertia, then the resistance to twisting during off-center shots is improved, but the aerodynamic drag force increases and club head speed decreases
Solution Approach 1:
The patent applies curved surfaces and aerodynamic shaping to the club head exterior, specifically using a rounded crown profile and optimized face curvature to reduce airflow separation and drag. The club head features a smooth, continuous curved surface that promotes laminar flow, contrasting with traditional flat or angular designs. This curvature principle directly addresses the aerodynamic drag issue while maintaining the large 460 cc volume and extended front-to-back dimension needed for high moment of inertia.
2Stability of the object's composition
If the front-to-back dimension is increased to achieve higher moment of inertia, then the stability during off-center shots is improved, but the aerodynamic drag force increases significantly
Solution Approach 1:
The patent optimizes specific geometric parameters of the club head including the crown profile curvature radius, face angle, and overall shape proportions. By carefully selecting and adjusting these dimensional parameters, the design achieves a club head with extended front-to-back dimension for high moment of inertia while maintaining aerodynamic efficiency. The specific parameter optimization allows the club to cut through air more effectively despite its large size.
