Golf Club Heads with Loft-Based Weight Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional golf club heads with fixed weight positions across varying loft angles fail to optimize ball flight and distance, as loft angle affects spin and flight characteristics, leading to suboptimal performance across different golf shots.
Innovation Solution
The golf club head incorporates loft-based weights positioned relative to the loft angle, with the weight's distance from the front end plane inversely proportional to the loft angle, allowing for adjustable weight placement to optimize spin and distance based on the desired ball flight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If fixed weight positions are used across varying loft angles, then manufacturing simplicity is maintained, but ball flight and distance performance are not optimized
Solution Approach 1:
The patent applies parameter changes by adjusting weight position based on loft angle variations. Specifically, the weight position is modified according to the loft angle of the club head to optimize spin rate and ball flight characteristics for each specific loft angle, thereby resolving the contradiction between manufacturing simplicity and performance optimization.
2Speed
If loft angle is increased to achieve higher ball flight, then launch angle improves, but flight distance decreases
Solution Approach 1:
The patent applies local quality by positioning weights at specific locations within the club head that are tailored to each loft angle. This localized weight placement optimizes the spin characteristics and center of gravity for each specific loft angle, enabling the club to achieve both desirable launch angle and flight distance by customizing the local mass distribution rather than using a uniform design.
3Reliability
If weight position is adjusted based on loft angle to optimize spin and distance, then ball flight performance is enhanced, but manufacturing complexity increases
Solution Approach 1:
The patent systematically applies parameter changes by establishing a relationship between loft angle and optimal weight position. This approach transforms the complexity of custom weight placement for each loft angle into a manageable parameter adjustment process, where the weight position is determined based on the specific loft angle of the club head, thereby optimizing performance while maintaining a systematic manufacturing approach.
