Embedded High Density Casting Golf Club Head
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for integrating high density metal pieces into golf club heads are limited by the need for multiple processing steps and lack of design freedom, making accurate and consistent placement challenging due to the forces exerted during welding, brazing, or adhesive application.
Innovation Solution
An embedded casting process that uses protrusions and gaps to prevent undesired translations or rotations of the high density metal piece, allowing for precise placement within the golf club head, involving the formation of a wax shell, ceramic coating, and pouring molten metal to create a gap between the metal piece and the club head body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If welding, brazing, or adhesive application is used to attach the high density metal piece, then the metal piece can be attached to the club head body, but multiple processing steps are required and design freedom is limited
Solution Approach 1:
The patent merges the attachment process with the casting process itself. The high density metal piece is positioned within the club head body cavity before casting, and the molten metal directly forms the attachment structure in one integrated process, eliminating separate welding, brazing, or adhesive application steps.
Solution Approach 2:
The high density metal piece is positioned in advance within the club head body cavity before the casting process begins. This preliminary positioning allows the metal piece to be precisely located at the desired center of gravity position before the molten metal is introduced to form the final attachment structure.
2Strength
If welding, brazing, or adhesive application is used to attach the high density metal piece, then the metal piece can be attached to the club head body, but accurate and consistent placement is difficult due to forces exerted during these processes
Solution Approach 1:
The high density metal piece is positioned in advance within the club head body cavity before the casting process begins. This preliminary positioning allows the metal piece to be precisely located at the desired center of gravity position before the molten metal is introduced, avoiding displacement from welding or adhesive forces.
Solution Approach 2:
The molten metal acts as an intermediary that simultaneously achieves attachment and precise positioning. Instead of applying external forces through welding or adhesives that may displace the metal piece, the molten metal flows around and solidifies with the metal piece already in its final desired position, maintaining placement precision.
3Strength
If traditional attachment methods are used, then the high density metal piece can be attached, but design freedom is limited
Solution Approach 1:
The patent merges the attachment process with the casting process itself, allowing the high density metal piece to be integrated into the club head body as a single molded structure. This integration provides greater design freedom in terms of shape, position, and configuration of the metal piece compared to traditional attachment methods.
Solution Approach 2:
The casting process allows for changes in physical parameters such as temperature, flow rate, and solidification rate to optimize the attachment structure. These parameter changes enable greater design flexibility in creating attachment structures with varying geometries, densities, and mechanical properties that would be difficult to achieve with traditional methods.
