Golf Putter with Curved and Straight Striking Faces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf putters do not incorporate a curved lower striking face and a substantially straight upper striking face, nor do they feature sandpaper or grit on the striking faces, which are necessary to induce top spin or over spin and prevent the golf ball from lifting during a putting swing.
Innovation Solution
A golf putter design featuring a curved lower striking face and a substantially straight upper striking face, with sandpaper or grit applied to the striking faces, along with an impact plate to induce back spin, and alignment lines for proper alignment, to ensure the golf ball receives top spin or over spin, preventing lifting during a putting swing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional putter head design is used, then the structure is simple and easy to manufacture, but the golf ball may lift during the putting swing due to insufficient spin control
Solution Approach 1:
The putter head incorporates a straight upper striking face portion with sandpaper or grit applied to it, creating a localized high-friction zone. This local quality enhancement at the striking face allows for reliable top spin or over spin generation without requiring complex structural changes to the entire putter head, thus resolving the contradiction between reliability and device complexity.
2Reliability
If sandpaper or grit is applied to the striking face, then top spin or over spin is induced preventing ball lifting, but the manufacturing process becomes more complex
Solution Approach 1:
The invention changes the surface friction parameter of the striking face by applying sandpaper or grit to the straight upper striking face portion. This parameter modification enables reliable top spin or over spin induction while maintaining relatively simple manufacturing processes, as the sandpaper or grit application is a straightforward surface treatment that does not require complex manufacturing steps.
3Measurement precision
If a straight upper striking face is used, then alignment precision is improved, but the traditional curved striking face design is altered
Solution Approach 1:
The putter head features an asymmetric striking face design with a straight upper striking face portion and a curved lower striking face portion. This asymmetric configuration improves alignment precision through the straight upper portion while maintaining the traditional curved shape at the lower portion, thus resolving the contradiction between measurement precision and shape preservation.
4Measurement precision
If the straight striking face extends upward from the curved striking face, then alignment capability is enhanced, but the height requirements increase
Solution Approach 1:
The straight upper striking face portion extends upward from the curved lower striking face portion to a height sufficient for alignment purposes (at least one-half the outer diameter of a regulation golf ball). This partial extension provides adequate alignment capability without excessive height increase, resolving the contradiction between measurement precision and length by implementing just enough straight face extension to achieve the alignment benefit.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design effectively induces top spin or over spin on the golf ball, preventing it from lifting during a putting swing, while allowing for precise alignment and improved striking characteristics.
Implementation Method 1
A piece of sandpaper may be secured to the straight and curved striking faces with any suitable method. Alternatively, grit may be glued directly to the straight and curved striking faces.
Implementation Method 2
The present invention provides a golf putter, which includes a curved lower striking face and a substantially straight upper striking face... causes the golf ball to have top spin or over spin

AI summary
A golf putter includes a putter head, a shaft and hand grip. The putter head includes a lower curved striking face and a substantially straight upper striking face. The straight striking face extends upward vertically from an upper end of the curved striking face. A height as measured from a bottom surface to a junction of the straight striking face and the curved striking face is at least one half the outer diameter of a regulation golf ball. An alignment striking line is created on a top and middle of the putter head. The hand grip is attached to one end of the shaft. The other end of the shaft is inserted into a top of the putter head. An impact plate is attached to a bottom and front of the putter head. A plurality of horizontal grooves are formed in the impact plate.
