Solution Overview

Problem

Golfers, especially beginners, face difficulties in mastering a standard swing posture and plane due to lack of coordination between the club and human structure, and existing training devices lack effective guidance for establishing the correct swing plane, leading to inaccurate and prolonged learning.

Innovation Solution

A golf swing practice method and device that establishes a guiding swing plane using plane geometry and tangent theory, with concave-convex parts or inductive prompting devices to monitor and correct the included angle between the club body and the swing plane, allowing immediate feedback on correct or incorrect swing actions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If golfers rely on individual feeling and professional coach guidance, then they can attempt to learn swing actions, but the learning process is prolonged and accuracy is low due to lack of real-time effective correction

Engineering Contradiction:
Improveswing action accuracyVSAvoidlearning time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies feedback principle by providing real-time visual feedback through a swing plane indicator that shows whether the club is on the correct swing plane during the swing motion. This immediate feedback allows golfers to correct their swing actions instantly without waiting for coach evaluation, thereby improving accuracy and reducing learning time.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces the mechanical system of manual coach evaluation with an automated optical/mechanical indicator system. The swing plane indicator mechanically or optically detects the club's position relative to the swing plane and provides visual feedback, substituting human judgment with an automated measurement system that provides more consistent and immediate feedback.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If existing training devices like target boards with coordinate scales are used, then golfers can calculate deviation degree, but there is no relevant guidance auxiliary equipment so golfers still need to grope by individual feeling

Engineering Contradiction:
Improvedeviation measurement capabilityVSAvoidintuitiveness of guidance
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent introduces an intermediary element - the swing plane indicator - that mediates between the complex coordinate system and the golfer. Instead of requiring golfers to interpret coordinate scales and calculate deviations, the indicator directly shows whether the club is on the correct swing plane, simplifying the feedback process and making it intuitive.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent employs color changes as a visual feedback mechanism. The swing plane indicator uses different colors (e.g., green for correct position, red for incorrect position) to immediately communicate swing accuracy, making the guidance intuitive and easy to understand without requiring mathematical calculations or interpretation of coordinate systems.

Inventive Principle:
Principle #32Color changes

3Adaptability or versatility

If guidance pieces with arc rings are used, then players can know swing steps and provide self-adjustment, but the track must be established through grope of players and does not have effective method for guiding swing plane

Engineering Contradiction:
Improveself-adjustment capabilityVSAvoidswing plane guidance accuracy
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent applies preliminary action by pre-establishing the correct swing plane geometry and positioning the indicator before the golfer begins practice. Unlike guidance pieces that require players to grope and establish their own tracks, this system comes pre-configured with the correct swing plane parameters, providing accurate guidance from the start without requiring players to figure out the correct path themselves.

Inventive Principle:
Principle #10Preliminary action

AI summary

The present invention provides a golf swing practice method, wherein a swing plane for guiding swing of a club is established, and a member for monitoring the condition whether an included angle is formed between a club body of the club and the swing plane is established outside the swing plane, which are taken as a basis for judging whether a swing action is right or wrong. The present invention also provides a golf swing practice device, which comprises a bracket (1) and a swing guiding frame (2) arranged on the bracket (1), wherein the swing guiding frame (2) forms a certain included angle with the ground; a guiding plane (2-3) for supporting the club is arranged on the surface of the swing guiding frame (2), and concave-convex parts (2-4) or an inductive device (5) are/is arranged outside the guiding plane (2-3), so as to prompt a wrong swing action that an included angle is formed between the club body of the club and the guiding plane during swing to a practicer.
