Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf ball hitting evaluation technologies are cumbersome, expensive, and provide inaccurate results due to the use of external equipment that interferes with the hitting process and has limited functionality.
Innovation Solution
Integrating sensors such as image acquisition, inertial measurement units, and microphones into the golf club to accurately measure contact, swing path, and ball trajectory, reducing reliance on external equipment and improving accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If external equipment (cameras, emission analyzers, radar) is used to obtain evaluation results, then measurement capability is provided, but device complexity increases and interference with hitting process occurs
Solution Approach 1:
The patent integrates multiple sensors (image acquisition sensor, inertial measurement unit, microphone) directly into the golf club structure, merging the evaluation system with the club itself. This eliminates the need for separate external equipment and reduces system complexity while maintaining measurement capability for contact position, swing path, and ball trajectory.
Solution Approach 2:
The integrated sensor system in the golf club performs multiple functions: image acquisition for visual analysis, inertial measurement for motion tracking, and acoustic detection for contact analysis. This multi-functional approach replaces multiple separate external devices with a single integrated system, reducing overall device complexity.
2Measurement precision
If external equipment is placed in front of or behind the hitter, then measurement is enabled, but ease of operation deteriorates due to inconvenience and interference
Solution Approach 1:
By merging the evaluation sensors with the golf club itself, the system eliminates the need for separate external equipment placement. The club becomes self-sufficient, carrying all necessary sensors internally, which removes the inconvenience of positioning external devices and prevents any interference with the hitting process.
Solution Approach 2:
The golf club performs self-measurement of its own hitting process through integrated sensors. The club structure itself serves as both the tool for hitting and the sensor platform for evaluation, eliminating the need for external measurement systems that would interfere with or complicate the operation.
3Ease of operation
If integrated sensors are used in the golf club, then ease of operation improves and interference is reduced, but device complexity increases
Solution Approach 1:
The patent embeds multiple sensors (image acquisition sensor, inertial measurement unit, microphone) within the internal structure of the golf club, nesting them in the club head or shaft. This integration approach, while increasing internal complexity, maintains external simplicity and improves ease of operation by eliminating external equipment needs.
4Measurement precision
If multiple types of sensors are integrated into the golf club, then measurement precision improves, but device complexity increases
Solution Approach 1:
The patent combines multiple sensor types (image acquisition, inertial measurement, acoustic sensing) into a single integrated system within the golf club. This merging approach consolidates what would otherwise be separate external devices into one unified platform, managing complexity through integration while achieving comprehensive measurement precision for contact position, swing path, and ball trajectory.
