Solution Overview
Problem
Existing methods lack a reliable and accurate system to measure the motion of a golf club using magnetism, which is crucial for determining the orientation and speed of the club head at impact to improve ball flight and training outcomes.
Innovation Solution
A golf club with ferro-magnetic dots or strips is swung through an array of magnetic sensors, capturing speed and motion data, and processed to display swing analysis and ball flight, utilizing a system with a display, computing, and recording capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If magnetic sensors are used to measure club motion, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent replaces traditional mechanical measurement systems with a magnetic field-based sensing system. Magnetic sensors detect the position and motion of ferro-magnetic dots on the club head through magnetic field interactions, eliminating the need for complex mechanical linkages or optical systems while achieving high measurement precision.
Solution Approach 2:
The patent introduces ferro-magnetic dots as intermediary elements attached to the club head. These dots serve as mediators between the club and the magnetic sensors, enabling non-contact measurement of club position and motion through magnetic field interactions, thereby simplifying the overall system while maintaining measurement accuracy.
2Measurement precision
If ferro-magnetic dots are attached to the club head, then measurement accuracy is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent divides the measurement task into discrete components by placing multiple ferro-magnetic dots at specific locations on the club head. Each dot provides independent position data, and collectively they enable comprehensive tracking of club head orientation and position, reducing the precision burden on individual dot placements.
Solution Approach 2:
The patent utilizes changes in magnetic field parameters (strength, direction, distribution) as the club moves through the magnetic sensors. By measuring multiple magnetic parameters simultaneously, the system can accurately determine club position and orientation even with moderate manufacturing tolerances in dot placement.
