Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional golf swing analysis systems relying solely on sound sensors are unreliable for capturing golfer's swing image data, leading to inaccurate determination of swing motions and play performance.
Innovation Solution
A motion sensor-based smart golf course round information system that includes a portable device with a motion sensor and GPS, connected to a server and database, which detects and analyzes golfer's swing motions, calculates play scores, and provides real-time rounding information to improve golf skills.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a sound sensor is used to detect the point of impact, then the system can identify when the golfer hits the ball, but the swing image data cannot be obtained reliably
Solution Approach 1:
The patent replaces the sound sensor-based detection system with a motion sensor-based system. The motion sensor directly detects the golfer's swing motion and the moment of impact through physical movement, eliminating the need for acoustic detection. This substitution resolves the contradiction by providing both reliable point of impact detection and reliable swing image data capture through the same motion sensing mechanism.
Solution Approach 2:
The patent introduces a motion sensor as an intermediary device between the golfer's swing action and the data capture system. The motion sensor acts as a mediator that translates the physical swing motion into detectable signals, enabling reliable detection of both the point of impact and the swing images without the limitations of sound sensor-based systems.
2Loss of time
If video recording starts at the point of impact, then the system captures only the relevant swing portion, but the swing motion analysis becomes inaccurate
Solution Approach 1:
The patent applies preliminary action by detecting the swing motion and point of impact before the actual ball strike occurs. The motion sensor continuously monitors the golfer's swing trajectory and identifies the moment of impact in advance, allowing the video recording to start at the optimal moment that captures the complete swing motion leading up to and including the impact, thereby maintaining both time efficiency and analysis accuracy.
3Device complexity
If conventional sound sensor systems are used, then the system structure remains simple, but the swing image extraction fails to reflect actual golfer performance
Solution Approach 1:
The patent replaces the simple sound sensor system with a motion sensor system that directly measures physical movement. Although the device complexity increases slightly, the reliability of swing image data dramatically improves because the motion sensor directly captures the golfer's actual swing motion and impact moment, providing accurate data that reflects real performance rather than relying on indirect acoustic detection.
