Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current training devices for bowling fail to effectively address the development of correct swing fundamentals, particularly rotational aspects of the arm, wrist, and hand, and are often bulky and inconvenient for portable use.
Innovation Solution
A compact, portable Bowling Visual Swing Training Apparatus utilizing line laser technology in conjunction with a Swing Reference Line to provide a visual indication of the bowling swing plane, including rotational movements, worn comfortably on the bowler's finger with adjustable securing mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If laser point devices are used to trace swing path, then swing plane indication is provided, but rotational aspects of arm, wrist, and hand cannot be reflected
Solution Approach 1:
The patent transitions from a single laser point (0D/1D) to a laser line (2D), enabling the visualization of both swing plane and rotational movements simultaneously. The laser line projected from the finger device creates a visual reference that encompasses multiple dimensions of swing mechanics including arm rotation, wrist rotation, and hand orientation throughout the bowling swing.
2Adaptability or versatility
If laser-based training devices are designed with comprehensive training capabilities, then swing fundamentals can be addressed, but the device becomes large and bulky
Solution Approach 1:
The patent extracts only the essential training function from complex training systems by using a simplified laser line projection mechanism mounted on the bowler's finger. This eliminates the need for bulky external equipment while maintaining the core training capability of providing visual feedback for swing plane and rotation.
Solution Approach 2:
The compact finger-mounted device performs multiple training functions simultaneously: indicating swing plane, monitoring arm rotation, tracking wrist rotation, and observing hand orientation. This single device replaces what would traditionally require multiple separate training tools.
3Measurement precision
If traditional bowling training devices are used, then swing path can be monitored, but rotational movements of arm, wrist, and hand are not addressed
Solution Approach 1:
By projecting a laser line instead of using traditional mechanical guides or video analysis, the device adds the dimension of visual feedback that simultaneously captures both linear swing path and rotational movements. The laser line serves as a reference against which all rotational aspects of the swing can be visually assessed.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances the learning and repetition of proper swing techniques by providing a visually measurable representation of directional and rotational aspects, promoting consistent and accurate bowling performance, suitable for bowlers of all ages and sizes.
Implementation Method 1
The laser module assembly (22) incorporates a lens thereon that produces a fan beam that generates a visible laser line
Data Source
AI summary
A Bowling Visual Swing Training Apparatus is disclosed. The embodiment specifically relates to training devices which assist a bowler in the development of correct and proper swing fundamentals. The embodiment utilizes laser line technology to provide an optical indication of the directional and rotational aspects of the bowling arm and hand throughout the swing as they relate to a preferred swing reference line, as a means of training and improving one's swing fundamentals and technique. The embodiment is compact in size, made of durable plastic, or other lightweight material, and is designed to be worn on a single finger, primarily, but not specifically, the index finger. The embodiment combines the laser module and its battery power pack into one compact unit, affixed to a comfortable finger plate that conforms to the user's finger, and is attached to the finger by means of elastic Velcro straps or other suitable securing means.
