Golf Club Head Ribs for Vibration Frequency Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Golf club heads with frequency-reducing features often result in undesirable auditory feedback and performance compromise, as they lower the vibration frequency below the desired 3,000 Hz range.
Innovation Solution
Incorporating ribs with both external and internal portions on the golf club head, specifically designed to increase the overall frequency by positioning external portions within concave areas and internal portions within the body, enhancing acoustical characteristics and maintaining performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If frequency-reducing features are added to the golf club head, then the volume is reduced and performance is maintained or increased, but the vibration frequency decreases below the desired 3,000 Hz range resulting in negative auditory feedback
Solution Approach 1:
The patent applies local quality by adding ribs only to specific regions of the golf club head where they will most effectively increase vibration frequency without significantly increasing overall volume. The ribs are strategically positioned to provide localized structural reinforcement that targets the acoustic properties of the head while maintaining the reduced volume design.
2Volume of moving object
If frequency-reducing features are added to the golf club head, then the volume is reduced and performance is maintained or increased, but the vibration frequency decreases resulting in negative auditory feedback
Solution Approach 1:
The patent converts the potentially harmful effect of reduced volume (which tends to lower vibration frequency) into a benefit by adding ribs that specifically target and increase the vibration frequency. The ribs transform the acoustic properties of the reduced-volume head, turning what would be a harmful frequency reduction into a beneficial high-frequency response that provides positive auditory feedback.
3Reliability
If ribs are added to increase vibration frequency, then the auditory feedback is improved, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the rib structure into multiple discrete elements that can be independently positioned and optimized. Rather than adding a single complex feature, the ribs are segmented into separate components that can be strategically placed at different locations on the golf club head, allowing for simplified manufacturing and assembly while achieving the desired frequency increase.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The addition of ribs significantly increases the vibration frequency, providing enhanced feel and auditory feedback while maintaining performance, with frequencies above 3,000 Hz, and offers structural reinforcement and improved consistency.
Implementation Method 1
The sound generated by a golf club is based on the rate, or frequency, at which the golf club head vibrates upon impact with the golf ball
