Golf Putting Training Device with Arc-Shaped Tunnel Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional golf putting training devices fail to simulate the natural swing path, which is not parallel to the flat ground, leading to inaccuracies in training.
Innovation Solution
A golf putting training device with a tunnel structure and arc-shaped bottom lines that connects the hitting surface vertically to the sidewalls, simulating the swing path and providing a visual and tactile feedback mechanism to align the putting direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the hitting surface is parallel to the flat ground, then the device structure is simple, but it fails to simulate the natural swing path
Solution Approach 1:
The patent applies curvature by designing the hitting surface with an arc-shaped configuration that matches the natural swing path of a golf putter. The hitting surface is positioned perpendicular to the arc-shaped bottom line at the rear end of the tunnel structure, creating a curved trajectory guide that simulates real putting motion rather than a straight linear path.
2Measurement precision
If the tunnel structure length is increased, then the training feedback accuracy is improved, but the error reduction effect is limited
Solution Approach 1:
The patent applies local quality by positioning the hitting surface at a specific location within the tunnel structure - at the rear end where it is perpendicular to the arc-shaped bottom line. This localized positioning optimizes the feedback mechanism at the critical hitting zone, providing accurate training feedback without requiring the entire tunnel structure to be excessively long.

AI summary
A golf putting training device comprises: a shaft, comprising a holding end and a connection end; a tunnel structure, comprising an opening at a front end of the tunnel structure, a hitting surface at a rear end of the tunnel structure, and two sidewalls to form two lateral sides of the tunnel structure, wherein the connection end of the shaft is connected to one of the sidewalls, wherein the sidewalls provide an arc shaped bottom line, wherein the hitting surface is connected to each of the sidewalls and is vertical to a tangent of the arc shaped bottom line at the rear end of the tunnel structure.
