Double-Grip Putter With Canted Aim Lines for Face Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional single-grip putters lack adequate control of the putter face throughout the stroke and do not provide a stable connection between the golfer's hands, and they fail to compensate for ball roll line deviation due to toe-up or toe-down putting.
Innovation Solution
A double grip putter with tapered grips and a canted aim line system that includes three-point gripping for a 'feel triangle' and marked aim lines to stabilize hand positioning and compensate for ball roll deviations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single grip is used on conventional putters, then the device complexity is reduced, but the control of the putter face and stability of hand connection deteriorates
Solution Approach 1:
The single grip is segmented into two separate grips (upper grip and lower grip) positioned at different locations on the shaft. This segmentation allows independent control points for the hands, improving putter face control and stability during the putting stroke while maintaining a relatively simple overall structure.
2Ease of operation
If different grips are used for upper and lower hands, then ease of operation is improved, but the feel consistency deteriorates
Solution Approach 1:
The upper grip and lower grip are designed with different characteristics suited to their specific locations and functions. The upper grip has a larger diameter for thumb placement and control, while the lower grip has a smaller diameter for finger placement. This local differentiation optimizes hand positioning and control while the consistent material and texture maintain uniform feel across both grips.
3Device complexity
If conventional aim lines are used, then the device complexity is reduced, but the accuracy of aiming compensation for toe-up or toe-down putting deteriorates
Solution Approach 1:
The aim lines are designed with asymmetric cant angles relative to the putter shaft axis. Different aim lines have different cant angles to compensate for the asymmetric effects of toe-up and toe-down putting positions. This asymmetric design allows accurate aiming compensation for various putting styles while maintaining a simple visual aiming system without complex mechanical components.

AI summary
A conventional length golf putter a first grip attached to the end of the shaft and a second grip attached to the shaft spaced from and below the first grip. The grips have matching frustoconical portions to create similar feel. The putter has a head with an alignment system to accommodate heel and toe putts.
