Muscle-Back Iron Head With Adjustable Back-Cavity Weighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an iron-type golf club head that improves mass distribution for inertial performance while maintaining the aesthetics of a full muscle-back iron.
Innovation Solution
The golf club head incorporates a lightweight back-cavity insert with a void to accommodate a CTP weight, allowing for adjustable mass characteristics and improved center of gravity, while retaining a traditional muscle-back appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a traditional muscle-back iron design is used, then aesthetic appearance is maintained, but mass distribution and inertial performance are insufficient
Solution Approach 1:
The patent combines a lightweight material (such as aluminum or titanium) with a dense material (such as tungsten or lead) to create a composite back-cavity insert. This composite structure allows the clubhead to achieve optimized mass distribution and improved inertial performance while maintaining the aesthetic appearance of a traditional muscle-back iron design.
2Strength
If mass is added to improve center of gravity, then inertial performance is enhanced, but the aesthetic appearance of a muscle-back iron is compromised
Solution Approach 1:
The patent places dense material strategically within the back-cavity insert to optimize mass distribution and center of gravity. This localized concentration of mass allows the clubhead to achieve enhanced inertial performance while the overall structure maintains the clean, traditional aesthetic appearance of a muscle-back iron without visible additions.
3Strength
If a lightweight back-cavity insert is added, then mass distribution is optimized, but device complexity increases
Solution Approach 1:
The patent integrates the back-cavity insert as a unified component within the clubhead structure. The insert is designed to fit into the back cavity and is secured through interference fit, mechanical retention features, or adhesive bonding, creating a combined structure that optimizes mass distribution without requiring complex assembly mechanisms or multiple separate components.
