Golf Iron Weighted with Tungsten for Trajectory Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sets of iron golf clubs lack optimal performance characteristics in terms of launch angle and distance due to uniform shaft lengths and club head masses, resulting in inconsistent ball trajectories across different irons.
Innovation Solution
A set of golf clubs with varying loft angles and distinct club head masses, incorporating tungsten weight members that comprise a significant portion of the club head mass, particularly in long and mid irons, to enhance performance characteristics and trajectory control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If uniform shaft lengths and club head masses are used in conventional iron sets, then manufacturing simplicity is maintained, but launch angle and distance consistency deteriorate
Solution Approach 1:
The patent applies local quality by varying the club head masses specifically in the long iron portion of the set (e.g., 3-iron through 6-iron) while maintaining uniform masses in the mid and short irons. This localized differentiation optimizes launch conditions for long irons without compromising the performance consistency of other clubs, thereby resolving the contradiction between manufacturing simplicity and performance reliability.
Solution Approach 2:
The patent implements parameter changes by introducing specific mass variations in the long iron club heads (e.g., increasing mass by 5-15 grams compared to conventional uniform designs). This parameter modification directly addresses the launch angle and distance consistency issue while maintaining a relatively simple manufacturing process, as the mass variation can be achieved through material selection or density adjustment rather than complex structural changes.
2Reliability
If club head masses are varied to improve trajectory control, then ball flight consistency improves, but manufacturing complexity increases
Solution Approach 1:
The patent reduces manufacturing complexity by applying mass variation only to the long iron portion of the set rather than uniformly across all clubs. This localized approach simplifies the overall manufacturing process while still achieving the desired ball flight consistency, as fewer clubs require specialized mass adjustment procedures.
Solution Approach 2:
The patent manages device complexity by implementing controlled parameter changes with specific mass differentials (e.g., 5-15 grams variation) rather than extensive mass variations across all clubs. This moderate parameter adjustment achieves trajectory control improvement while keeping manufacturing processes relatively simple and manageable.
3Reliability
If tungsten weight members are added to club heads, then launch angle and distance performance improve, but club head mass increases
Solution Approach 1:
The patent applies the weight increase locally only to the long iron club heads rather than uniformly across the entire set. This allows the performance benefits of additional tungsten mass (improved launch angle and distance) to be realized where most needed, while keeping the overall set weight manageable and the performance impact of the added mass minimized.
Solution Approach 2:
The patent optimizes the relationship between performance improvement and weight penalty by carefully controlling the amount of tungsten added (resulting in 5-15 gram mass increases). This parameter optimization ensures that the performance benefits in terms of launch angle and distance consistency are achieved while minimizing the negative impact of increased club head mass.
