Solution Overview
Problem
Existing golf training devices fail to provide effective resistance to strengthen the axial skeleton and lower extremities while maintaining proper swing orientation and acceleration, and they lack visual feedback for optimal swing path alignment.
Innovation Solution
A golf swing training system with an optically reflective surface and laser light projection for visual guidance, combined with a resistance device to strengthen core, hip, and lower extremity muscles, allowing users to practice proper swing dynamics and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing training devices restrict swing path to a plane, then swing orientation is improved, but resistance to strengthen axial skeleton and lower extremities is not provided
Solution Approach 1:
The device merges two previously separate functions into one integrated system: (1) the swing path guidance function using laser projection and reflective surface, and (2) the resistance training function using elastic resistance bands anchored to fixed structures. This combination allows simultaneous provision of visual feedback for swing orientation and mechanical resistance for strengthening axial skeleton and lower extremities.
Solution Approach 2:
The training device achieves multi-functionality by incorporating both visual guidance components (laser sources, reflective surface) and resistance training components (elastic bands, anchors). This single device simultaneously performs swing path correction and muscle strengthening, eliminating the need for separate training devices.
2Measurement precision
If existing devices train swing path alignment, then swing plane is improved, but visual feedback for club head orientation is not provided
Solution Approach 1:
The device implements visual feedback by projecting laser lines that reflect off a reflective surface (such as a golf club or reflective tape) back to the user. This provides real-time information about club head orientation and swing plane, allowing the golfer to see and correct their swing path without losing critical orientation information.
Solution Approach 2:
The reflective surface acts as an intermediary between the laser projection system and the golfer's eyes. The laser lines reflect off this surface to create visible feedback about swing orientation, mediating the transfer of orientation information from the guidance system to the user in a visually perceivable form.
3Stability of the object's composition
If existing devices restrict swing path, then proper swing path is maintained, but resistance for progressive acceleration training is not supplied
Solution Approach 1:
The device combines swing path restriction mechanics with resistance training mechanics. The elastic resistance bands are integrated into the swing path guidance system, providing both the structural framework for path restriction and the mechanical resistance for acceleration training simultaneously.
4Measurement precision
If existing devices attach to hands or wrists, then grip orientation is trained, but resistance to strengthen core and lower extremities is not provided
Solution Approach 1:
The device extracts the resistance training function from the grip training function. While the laser guidance system continues to train grip and hand orientation, the resistance bands are anchored to fixed structures external to the body, providing resistance that targets core and lower extremity muscles rather than just the hands and wrists.

AI summary
A golf swing training and exercise system includes an optically reflective device, a golf device, a pair of light source devices, and a resistance device. The golf device has a center section that is placed on the back of a user during a golf swing training and exercise routine, two end sections extending outwardly from the center section, and a pair of intermediate sections that are disposed between and interconnect the center section and the respective end sections to one another and on which the user's hands or forearms are placed during the golf swing training and exercise routine. The light source devices are connected to respective distal ends of the end sections for projecting light beams on a reflective surface of the optically reflective device during a golf swing training and exercise routine. The resistance device is removably connected to the golf device to apply a resistance in at least one direction of movement of the golf device during the golf swing training and exercise routine.
