Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current golf club manufacturing processes are inflexible and costly, failing to accommodate individual golfer needs such as optimized lie angle, loft angle, and weight distribution, leading to suboptimal performance and increased costs for custom-fitted clubs.
Innovation Solution
The method involves using an interface for golfers to input personal data and preferences, which are then used to select and fabricate customized golf club components through layer-by-layer construction techniques such as metal sintering, allowing for precise control over club design parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional manufacturing processes (forging or casting) are used to produce golf club heads, then manufacturing efficiency and cost-effectiveness are improved, but the ability to accommodate individual golfer needs and optimize club design parameters deteriorates
Solution Approach 1:
The patent applies parameter changes by utilizing layer-by-layer construction methods that enable precise control over club design parameters such as lie angle, loft angle, and weight distribution. This additive manufacturing approach allows continuous variation of geometric parameters without requiring new molds or tooling, thus achieving customization while maintaining manufacturing efficiency.
Solution Approach 2:
The invention segments the club head into multiple layers that can be independently constructed and optimized. Each layer can be tailored with specific material properties, densities, and geometric features to meet individual golfer requirements, while the overall manufacturing process remains automated and efficient through computer-controlled deposition.
2Manufacturing precision
If individualized golf clubs are produced through conventional methods, then customization accuracy is improved, but manufacturing costs and complexity increase dramatically
Solution Approach 1:
The patent replaces complex mechanical manufacturing systems (molds, machining tools, assembly lines) with an additive manufacturing system that builds club heads layer by layer under computer control. This substitution eliminates the need for expensive mold fabrication and tooling changes, reducing manufacturing complexity while maintaining high customization accuracy through digital modeling.
Solution Approach 2:
The invention changes the manufacturing approach from subtractive (machining) or formative (casting) processes to additive construction, enabling precise control over material placement, density, and distribution. This allows accurate customization of club parameters without requiring complex post-processing or multiple manufacturing steps.
3Measurement precision
If professional fitters are used to help golfers select and customize clubs, then club-golfer matching accuracy is improved, but costs and accessibility deteriorate
Solution Approach 1:
The patent implements a self-service system where golfers can independently input their swing characteristics, body measurements, and performance goals into a computer system that automatically analyzes the data and recommends optimized club specifications. This eliminates the need for professional fitters while maintaining matching accuracy through algorithmic analysis and database comparisons.
Solution Approach 2:
The invention incorporates feedback mechanisms where the system continuously refines club recommendations based on golfer input data, swing analysis, and performance outcomes. The computer system uses stored database information and iterative optimization to improve matching accuracy over time, making expert-level club selection accessible to any golfer with internet access.
