Multi-material Golf Club Head Weight System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current golf club weights are limited by the use of single materials with low or high density, which restricts the range of weight adjustments and increases manufacturing costs due to brittleness and difficulty in threading high-density materials.
Innovation Solution
A two-part weight system comprising a low-density first part and a high-density second part, allowing for interchangeable high-density components to achieve multiple weight ranges while reducing manufacturing costs and improving durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If high density material is used for weight, then weight adjustment range is improved, but ease of manufacture deteriorates due to threading difficulty and brittleness
Solution Approach 1:
The weight is divided into two separate parts: a low-density threaded portion and a high-density weight portion. This segmentation allows each part to be optimized for its specific function - the low-density part can be easily threaded while the high-density part provides the desired weight adjustment range.
Solution Approach 2:
The weight system combines two different materials with different density characteristics. The low-density material (such as stainless steel) is used for the threaded portion, while the high-density material (such as tungsten) is used for the weight portion, creating a composite structure that achieves both ease of manufacture and weight adjustment capability.
2Weight of moving object
If high density material is used for weight, then weight adjustment range is improved, but reliability deteriorates due to brittleness and cracking
Solution Approach 1:
By separating the weight into two parts, the high-density material is used only for the weight portion where brittleness is not an issue, while the low-density material forms the threaded portion that requires durability and resistance to cracking during installation and use.
Solution Approach 2:
The composite structure uses low-density material for the threaded portion which requires high reliability and resistance to cracking, while high-density material is used for the weight portion where density is the primary requirement. This material selection strategy optimizes both reliability and weight adjustment capability.
3Device complexity
If single material is used for weight, then device complexity is reduced, but adaptability deteriorates due to limited weight ranges
Solution Approach 1:
The low-density threaded portion serves as a universal component that can accommodate multiple different high-density weight portions with varying weights. This multi-functional design allows a single threaded housing to work with various weight insertions, providing adaptability across multiple weight ranges without requiring separate designs for each weight.
Solution Approach 2:
The weight system allows for dynamic adjustment by enabling the removal and replacement of different high-density weight portions within the standardized low-density threaded housing. This dynamic configuration capability provides versatility in weight adjustment while maintaining a consistent basic structure.
