Telescoping Golf Stance Trainer with Retractable Arms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Golfers face challenges in maintaining correct stance and alignment when addressing a golf ball, particularly on sloped greens, which affects the trajectory and direction of the ball, and existing training devices lack portability and adjustability for practicing various swing techniques.
Innovation Solution
A portable, retractable golf stance trainer with three telescoping arms that can be extended and adjusted to form a 'T' shape, allowing for precise alignment of feet and putter path, enabling practice of different stances and swing directions, and compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a fixed, non-retractable training device is used, then alignment precision is maintained, but portability and storage convenience deteriorate
Solution Approach 1:
The device employs telescoping arms that can extend and retract, transforming a static structure into a dynamic one. The arms maintain precise alignment measurements when extended but can be collapsed for portable storage, resolving the contradiction between measurement precision and portability
Solution Approach 2:
The telescoping arms nest within each other when retracted, allowing the device to be compacted to a small size for easy transport while maintaining full extension capability for precise alignment training when deployed
2Adaptability or versatility
If a non-adjustable training device is used, then structural simplicity is maintained, but adaptability for different swing techniques deteriorates
Solution Approach 1:
The device incorporates adjustable arm lengths and variable angle configurations, allowing golfers to adapt the training device to different swing techniques and green conditions without requiring multiple specialized devices
Solution Approach 2:
The training device serves multiple functions through its adjustable components - it can accommodate different stance widths, swing arcs, and alignment angles, making it a universal training tool for various golf situations rather than a single-purpose device
3Measurement precision
If a large, fully extended training device is used, then alignment accuracy is improved, but storage space requirements increase
Solution Approach 1:
The telescoping arms nest within each other when not in use, reducing the device volume from a fully extended 36-inch span to a compact folded configuration that requires minimal storage space while maintaining full alignment accuracy when deployed
Solution Approach 2:
The device transitions between a compact static storage state and an extended dynamic training state, providing full alignment accuracy during use while minimizing storage space requirements when collapsed

AI summary
A golf swing stance trainer has a hub and a central telescoping arm connected to the hub. Side telescoping arms are connected to the hub for swinging outward to positions perpendicular to the central arm. The hub has ground-engaging cleats on a lower surface. The central arm is selectively extended outward for position with respect to a ball position. The side arms are selectively extended outward to indicate desired foot positions. The central arm has an extension with a pivot for sliding outward from the central arm for training position and direction of a golf ball and direction and extent of a swing. Arm extensions are related to an individual user and club selection. The arms are telescoped inward and the side arms are swung inward for carrying. The hub includes a hinge rod with a central receive through which a connected on the central arm slides.
