Golf Club Head Weight Assembly for Center of Gravity Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in golf club head design is to effectively integrate high-density weights that are compatible with the club head materials, ensuring structural integrity and proper weight distribution while accommodating aesthetic and performance considerations, as existing bonding methods often fail to provide sufficient strength or result in unwieldy weight configurations.
Innovation Solution
A multi-density weight system comprising a first weight component with a low density material for bonding with the club head and a second high-density component, which can be bounded or partially bounded by the first component, using methods like additive manufacturing, swedging, epoxy bonding, or sintering, and coupled to the club head via welds, brazing, or compression rings, allowing for precise control over weight distribution and center of gravity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If high-density weight materials are used to manipulate club head center of gravity, then weight distribution control is improved, but bonding compatibility with club head materials deteriorates
Solution Approach 1:
The weight system is divided into multiple components: a first weight component made of bonding-compatible material (e.g., stainless steel) and a second weight component made of high-density material (e.g., tungsten). The first weight component bonds to the club head, while the second weight component is secured to the first weight component, separating the bonding function from the high-density weight function.
Solution Approach 2:
The first weight component acts as an intermediary between the club head and the high-density second weight component. It provides a bonding interface compatible with club head materials while supporting and positioning the high-density weight material that would otherwise be incompatible for direct bonding.
2Manufacturing precision
If high-density weight materials are used to achieve proper weight distribution, then center of gravity adjustment is improved, but structural integrity deteriorates
Solution Approach 1:
The weight system separates structural and weighting functions into different components. The first weight component provides structural integrity and bonding compatibility, while the second weight component provides high-density mass for center of gravity adjustment, reducing stress on bonding interfaces.
3Adaptability or versatility
If weights are made larger to achieve proper distribution within the club head body, then weight placement flexibility is improved, but aesthetic appearance deteriorates
Solution Approach 1:
The system changes the density parameter of the weight materials, using high-density materials to achieve the required mass in smaller volumes. This allows flexible weight placement throughout the club head body while maintaining compact weight configurations that preserve aesthetic appearance.
