Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional golf club fitting methods are used, then the fitting process is simple and quick, but the club selection does not adequately account for individual golfer swing mechanics and preferences

Engineering Contradiction:
Improveswing analysis accuracyVSAvoidfitting system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The fitting system segments the club selection process into multiple independent analysis components: optical motion tracking data analysis, machine learning predictive algorithms, and multiple club specification parameters (shaft flex, length, grip size, lie angle, loft). Each component processes specific aspects of swing mechanics independently, then integrates results to provide comprehensive club recommendations that accurately account for individual golfer characteristics.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces an optical motion tracking system as an intermediary device between the golfer and the club fitting process. This intermediary captures detailed swing mechanics data through optical sensors and cameras, translating physical swing movements into quantifiable metrics that feed into machine learning algorithms, thereby enabling precise measurement without directly altering the golfer's natural swing.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If machine learning analysis with optical motion tracking is implemented, then personalized club recommendations are provided, but the data processing time and computational resources increase

Engineering Contradiction:
Improveclub fitting personalizationVSAvoiddata processing time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by pre-processing optical motion tracking data during the swing capture phase, organizing raw data into structured formats suitable for machine learning analysis. The machine learning models are pre-trained on extensive swing data sets before actual fitting sessions, enabling rapid inference during the actual fitting process. This preliminary preparation reduces real-time computational requirements and accelerates the delivery of personalized club recommendations.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces traditional mechanical club fitting methods (manual observation, physical trial-and-error) with computational systems comprising machine learning algorithms and optical motion tracking. This substitution transforms the fitting process from a time-intensive manual procedure to an automated computational analysis that can process multiple swing parameters simultaneously and generate personalized recommendations more efficiently.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If comprehensive swing data is collected and analyzed, then accurate predictive algorithms are generated, but the complexity of the fitting system increases

Engineering Contradiction:

Solution Approach 1:

The patent implements a universal machine learning framework that handles multiple club specification parameters (shaft flex, length, grip size, lie angle, loft) through a single integrated predictive algorithm. This multi-functional system processes diverse swing data types (optical tracking coordinates, swing speed, arc radius, impact position) and generates comprehensive club recommendations across all parameters simultaneously, reducing the need for separate analysis systems for each parameter while maintaining high accuracy.

Inventive Principle:
Principle #6Universality (Multi-functionality)
