Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a golfer uses existing systems to determine ball striking performance for multiple golf clubs and golf balls, then the golfer can compare performance across different equipment, but the golfer must physically test each combination under various atmospheric conditions, which is extremely time-consuming and impractical

Engineering Contradiction:
Improveball striking performance prediction accuracyVSAvoidtesting time for multiple club and ball combinations
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent creates a virtual copy of the golfer's swing and the golf clubs through computer simulation. Instead of physically testing each club-ball combination, the system uses digital models to replicate the swing mechanics and predict performance outcomes. This allows the golfer to evaluate multiple equipment combinations without physical interaction, resolving the contradiction between accurate performance measurement and time consumption.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The system performs preliminary calculations and simulations of ball striking performance before any physical testing occurs. By pre-computing the expected performance metrics for various club and ball combinations based on the golfer's swing characteristics, the system eliminates the need for sequential physical testing, thereby saving time while maintaining measurement precision.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If a golfer tests each driver with each golf ball under each atmospheric condition to find the optimal match, then the most accurate performance data is obtained, but the number of tests required becomes prohibitively large

Engineering Contradiction:
Improveperformance prediction reliabilityVSAvoidtesting efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent replaces the mechanical system of physical testing with a computational simulation system. Instead of physically striking golf balls with drivers under various atmospheric conditions, the system uses computer algorithms to calculate performance outcomes based on input parameters including swing characteristics, equipment specifications, and atmospheric conditions. This substitution maintains reliability through accurate physical modeling while dramatically improving productivity by eliminating the need for numerous physical tests.

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

Solution Approach 2:

The system varies input parameters (swing speed, club loft, ball type, atmospheric conditions) in the simulation to predict performance across different scenarios. By changing parameters computationally rather than physically reconfiguring equipment and environmental conditions, the system can evaluate numerous combinations efficiently while maintaining reliable predictions based on established physics principles.

Inventive Principle:
Principle #35Parameter changes

3Loss of information

If high speed camera technology is used to gather information on a golfer's swing, then detailed swing metrics can be obtained, but the system cannot predict performance for equipment not physically tested

Engineering Contradiction:
Improveswing information completenessVSAvoidequipment combination flexibility
Core Design Contradiction:
Loss of informationVSAdaptability or versatility

Solution Approach 1:

The patent introduces a computer simulation model as an intermediary between the captured swing data and the performance prediction for untested equipment. The simulation model acts as a mediator that takes the golfer's swing characteristics (obtained through camera analysis) and applies them to virtual representations of different golf clubs and balls, predicting performance outcomes without requiring physical testing of each combination. This intermediary enables both information completeness and equipment flexibility.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The simulation system serves multiple functions: it analyzes the golfer's swing, models various golf clubs and balls, predicts performance for any combination, and allows comparison across equipment. This universal tool replaces the need for separate physical testing procedures for each equipment combination, maintaining information completeness while dramatically increasing adaptability to different club and ball selections.

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

AI summary

A method for a predicting golfer's performance is disclosed herein. The method inputs the pre-impact swing properties of a golfer obtained from a CMOS imaging system, a plurality of mass properties of a first golf club, and a plurality of mass properties of a first golf ball into a rigid body code. Ball launch parameters are generated from the rigid body. The ball launch parameters, a plurality of atmospheric conditions and lift and drag properties of the golf ball are inputted into a trajectory code. This trajectory code is used to predict the performance of a golf ball if struck by the golfer with the golf club under the atmospheric conditions. The method can then predict the performance of the golf ball if struck by the golfer with a different golf club. The method and system of the present invention predict the performance of the golf ball without the golfer actually striking the golf ball.
