Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for positioning tee-markers on golf courses are inaccurate, require frequent re-adjustment, and lack reproducibility due to reliance on telescopic rods and subjective human assessment, leading to inefficiencies in setup time and consistency.
Innovation Solution
A device that emits bundles of light rays from a high point, projecting marking positions onto the ground at acute angles to define precise tee-marker locations, allowing for accurate and reproducible placement with minimal effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If telescopic or removable rods are used to indicate tee-marker positions, then the distance between tee-markers can be defined, but the device requires frequent re-adjustment and readjustment for each teeing area, resulting in inaccuracy and loss of time
Solution Approach 1:
The patent replaces the mechanical telescopic or removable rods with an optical system using laser beams to indicate tee-marker positions. The device includes a housing with a laser unit that emits laser beams along a direction of play, and a distance indicator that projects markings onto the ground at specific distances (e.g., 4 meters and 6 meters). This optical substitution eliminates the need for physical measurement rods and their associated setup time while maintaining positioning accuracy.
Solution Approach 2:
The device pre-configures multiple distance indicators at standard tee-marker distances (4 meters and 6 meters) within the housing. These distance indicators are prepared in advance and can be quickly activated without requiring on-site measurement or adjustment. The laser unit and distance indicators work together to immediately establish accurate tee-marker positions when the device is placed on the ground.
2Measurement precision
If telescopic or removable rods are used to define tee-marker distances, then positioning can be achieved, but the device lacks alignment capability in the direction of play
Solution Approach 1:
The patent replaces mechanical alignment tools with an optical laser system. The laser unit emits a visible laser beam along the direction of play, providing an optical reference line for alignment. This laser indication makes it easy to align the device with the intended direction of play without requiring complex mechanical alignment procedures or additional tools.
3Adaptability or versatility
If subjective human assessment is used to position tee-markers, then flexibility is maintained, but accuracy and reproducibility are compromised
Solution Approach 1:
The patent replaces subjective human assessment with an objective optical measurement system. The laser unit provides a precise directional reference, and the distance indicators project markings at exact predetermined distances (4 meters and 6 meters) onto the ground. This objective system eliminates human judgment variability while maintaining the flexibility to position tee-markers at standard distances, thereby improving both accuracy and reproducibility.
