Curved Putter Face Geometry to Prevent Downward Ball Strike
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Golf putters with striking faces that tend to strike the ball downward toward the ground are undesirable.
Innovation Solution
A golf putter design featuring a front striking face with a first circular curvature extending from a top to a bottom portion, where the bottom portion is generally perpendicular to the putter head's bottom surface and the top portion forms an acute angle with the bottom surface, preventing downward striking.

Engineering Contradiction Analysis
1Object-affected harmful factors
If the striking face is designed with a conventional shape, then the putter structure is simple, but the ball may be struck downward toward the ground which is undesirable
Solution Approach 1:
The striking face is designed with a circular curvature that extends from the top portion to the bottom portion, creating a rounded surface geometry. This curvature prevents the ball from being struck downward by distributing the impact force across a curved surface rather than a flat or angled face, thereby eliminating the harmful downward striking effect while maintaining structural simplicity.
2Measurement precision
If the bottom portion of the striking face is made perpendicular to the bottom surface, then control and accuracy are improved, but the angle configuration becomes more complex
Solution Approach 1:
The striking face employs different angular configurations at different locations: the bottom portion is perpendicular to the bottom surface of the putter head to provide stability and control, while the top portion forms an acute angle with the bottom surface. This localized differentiation of geometric properties optimizes performance at each region without requiring complex overall design.
Solution Approach 2:
The striking face features an asymmetric angular configuration where the bottom portion forms a perpendicular angle while the top portion forms an acute angle with the bottom surface. This asymmetric design provides distinct functional benefits at different heights of the striking face, improving control and accuracy while maintaining a relatively simple geometric definition.

AI summary
A golf putter can include a shaft; a hosel connected to the shaft; a putter head connected to the hosel, the putter head having a front striking face, the front striking face having a first circular curvature that extends from a top portion of the front striking face to a bottom portion of the front striking face, wherein: the bottom portion of the front striking face and the bottom surface of the putter head form a first angle that is not obtuse; and the top portion of the front striking face and the bottom surface of the putter head form a second angle that is acute.
