Golf Club Sensor Unit for Misplacement Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf club alert systems often activate alarms unnecessarily due to clubs being used during normal play, are cumbersome, or require high-power devices with short battery life, and fail to accurately detect when a club is misplaced.
Innovation Solution
A golf club sensor unit with a light sensor and 3-axis accelerometer that determines when a club is removed from or returned to a golf bag, using a processor to differentiate between normal use and misplacement, and communicates with a software application to provide alerts only when a club is genuinely misplaced.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RF transmitters are attached to golf clubs to detect misplacement, then club tracking capability is improved, but battery life deteriorates due to continuous high-power transmission requirements
Solution Approach 1:
The system uses periodic action by implementing a removal timer that is activated when a club is detected outside the bag and deactivated when the club is returned. The alarm only triggers after the timer expires, creating a periodic detection cycle rather than continuous monitoring. This reduces power consumption while maintaining reliable tracking of club misplacement events.
2Length of stationary object
If RF transmitters continuously transmit signals over 100 yards, then detection range is improved, but power consumption increases requiring larger batteries
Solution Approach 1:
The system employs periodic action by using a removal timer mechanism that activates detection only when needed (when club removal is detected) rather than maintaining continuous transmission. The timer-based approach allows the system to achieve sufficient detection range during active periods while dramatically reducing average power consumption.
3Measurement precision
If alarms are activated whenever a club is removed from the bag, then misplacement detection sensitivity is improved, but user annoyance increases due to false alarms during normal play
Solution Approach 1:
The system applies preliminary action by activating a removal timer when a club is first detected outside the bag, before issuing an alarm. This preliminary timing action allows the system to wait and see if the club is returned during normal play, thereby preventing false alarms while maintaining sensitivity to actual misplacement events.
Solution Approach 2:
The removal timer creates a periodic detection window where the system monitors for club return before triggering an alarm. This periodic check reduces false alarms during normal play while maintaining accurate detection of genuine misplacement events, balancing sensitivity with user comfort.
4Loss of information
If mechanical devices are used to hold clubs vertically for visibility, then club visibility is improved, but device complexity and burden on golfer increases
Solution Approach 1:
The system replaces the mechanical approach of holding clubs vertically with an electronic sensor-based detection system. The sensor unit detects club position and the processor determines misplacement through logical analysis, eliminating the need for complex mechanical visibility devices while achieving the same goal of preventing lost clubs.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively reduces false alarms by accurately determining when a club is in use versus misplaced, extending battery life, and providing timely alerts on a golfer's smartphone or other devices, ensuring clubs are not left behind.
Implementation Method 1
a light sensor disposed in the housing and configured to detect light exterior of the housing
Implementation Method 2
an angle sensor disposed in the housing and configured to determine the orientation of the golf club
