Blade Iron Golf Club Muscle Structure for Face-Centered Gravity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Muscle-back and blade-type golf clubs have limitations in center of gravity placement, feel, and shot shaping capabilities, with conventional blade irons having the center of gravity away from the face center, affecting performance and feedback.
Innovation Solution
A blade-type iron golf club design with a sloped muscle portion and a smooth arcuate blade interface, redistributing mass to bring the center of gravity closer to the face center, enhancing impact efficiency and feel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If mass is concentrated in the muscle portion extending along the sole and entire length of the club head, then structural integrity and traditional blade iron feel are maintained, but the center of gravity remains away from the face center location, reducing impact efficiency
Solution Approach 1:
The patent applies local quality by creating a non-uniform mass distribution within the muscle portion. The muscle portion has greater thickness and mass concentration in specific regions (particularly toward the toe side) compared to other areas. This localized mass concentration shifts the center of gravity closer to the face center while preserving the overall structural integrity and traditional blade iron feel associated with the muscle-back design.
2Adaptability or versatility
If the center of gravity is located away from the face center location on the heel and sole side, then traditional blade iron characteristics are maintained, but shot shaping capabilities and feedback are reduced
Solution Approach 1:
The patent changes the critical parameter of center of gravity location by redistributing mass within the muscle portion. By increasing the thickness and mass concentration in specific areas of the muscle portion, the center of gravity is shifted from its traditional position on the heel and sole side to a position closer to the face center. This parameter change improves shot shaping capabilities and feedback while maintaining the traditional blade iron aesthetic and feel.
3Strength
If perimeter weighting elements and reinforcement ribs are added to cavity back clubs, then structural stiffness is improved, but the ability to shape shots is minimized
Solution Approach 1:
The patent segments the mass distribution into distinct functional zones within the muscle portion. Rather than using uniform perimeter weighting, the muscle portion is designed with varying thickness and mass concentration in different regions. This segmentation allows the club to maintain structural stiffness through strategic mass placement while preserving shot shaping ability through the natural flexing characteristics of the segmented muscle structure during the swing and impact.

AI summary
In general, aspects of this invention relate to blade-type iron golf clubs or golf club heads. The blade-type golf club head may comprise a body forged of a metal material. The body may include a hosel, a top surface, a sole, a heel, a toe, a ball striking surface, and a rear surface opposite the ball striking surface. The rear surface may have an upper blade portion and a lower muscle portion with the upper blade portion separated from the lower muscle portion by a blade interface. The lower muscle portion may have a muscle portion surface are that includes a heel muscle surface area measured from the ball striking centerline to the heel and a toe muscle surface area measured from the ball striking centerline to the toe. The toe muscle surface area may make up at least 60% of the muscle portion surface area. The mass distribution of the lower muscle portion moves the center of gravity of the club head closer to the face center location.
