Innovation Solution

A system using consumer electronic devices, such as personal computers and mobile communication devices, to analyze impact data through sound signals and sensor data from golf clubs and balls, determining club head speed, impact location, and golf ball quality, without the need for expensive equipment or manual installation of sensors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If specialized impact sensors and analysis systems are used to determine club head speed and impact location, then measurement precision is improved, but device complexity and cost increase

Engineering Contradiction:
Improveclub head speed measurementVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical impact sensors with acoustic field-based detection using microphones and signal processing. Sound waves generated during club-ball impact are captured and analyzed to determine impact location and club head speed, substituting mechanical measurement systems with acoustic field-based systems that are simpler and more cost-effective.

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

Solution Approach 2:

The patent introduces sound waves as an intermediary medium to transfer information about the impact event. Instead of directly measuring physical parameters with complex sensors, the system uses acoustic signals as a mediator that carries information about impact location and club head speed, which can then be extracted through signal processing.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If manual methods like impact tape are used to determine impact location, then device complexity is reduced, but measurement precision and ease of operation deteriorate

Engineering Contradiction:
Improvesystem complexityVSAvoidimpact location measurement
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent replaces manual impact tape methods with acoustic field-based detection. Instead of physically marking the club face and manually determining impact location, the system uses microphones to capture sound waves and computational algorithms to automatically determine impact location with higher precision.

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

Solution Approach 2:

The system performs automatic analysis of impact data without requiring manual intervention. The microphones capture sound waves and the processing system automatically determines impact location and club head speed, eliminating the need for users to manually apply impact tape or interpret physical marks.

Inventive Principle:
Principle #25Self-service

3Measurement precision

If expensive specialized equipment is used for swing analysis, then measurement precision is improved, but ease of operation and accessibility worsen

Engineering Contradiction:
Improveswing analysis accuracyVSAvoiduser accessibility
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent uses inexpensive consumer electronics components (microphones, processors) instead of expensive specialized sensors. The system leverages readily available, low-cost technology that can be easily acquired and operated by typical golfers, making swing analysis accessible to a broad audience rather than requiring costly professional equipment.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The system uses general-purpose consumer electronics devices that can perform multiple functions including swing analysis, rather than specialized single-purpose equipment. This universality makes the system more accessible and easier to operate, as users can leverage devices they already own or can easily obtain.

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

4Loss of information

If comprehensive impact data collection is implemented, then information completeness is improved, but loss of time for data processing increases

Engineering Contradiction:
Improveimpact data completenessVSAvoiddata processing time
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The system performs real-time analysis of impact data as the sound waves are captured, rather than requiring post-processing of raw data. The computational algorithms immediately determine impact location and club head speed from the acoustic signals, providing instant feedback without time-consuming data processing delays.

Inventive Principle:
Principle #10Preliminary action

AI summary

Golf performance and equipment characteristics may be determined by analyzing the impact between a golf ball and an impacting surface. In some examples, the impacting surface may be a golf club face. The impact between the golf ball and the surface may be measured based on sound and/or motion sensors (e.g., gyroscopes, accelerometers, etc.). Based on motion and/or sound data, various equipment-related information including golf ball compression, club head speed and impact location may be derived. Such information and/or other types of data may be conveyed to a user to help improve performance, aid in selecting golf equipment and/or to insure quality of golfing products.
