Solution Overview
Problem
Existing golf distance measurement technologies, such as laser and GPS methods, face challenges in accurately recommending shot distances due to difficulties in aiming at long distances and errors in coordinate measurements, respectively, without effectively considering wind characteristics.
Innovation Solution
A distance recommendation device for golf that calculates a recommended shot distance by considering wind characteristics, including a wind characteristic measurement unit to measure wind direction and speed, and a wind influence reflection unit to adjust the shot distance based on these measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If laser distance measurement method is used, then measurement precision is improved, but ease of operation deteriorates due to difficulty in accurate aiming at long distances
Solution Approach 1:
The patent combines laser distance measurement capability with GPS positioning capability into a single integrated device. The laser measurement unit provides precise distance measurement when aimed at the target, while the GPS receiver provides position-based distance calculation that does not require precise aiming. The control unit integrates both measurement results to provide accurate distance information, thus resolving the contradiction between measurement precision and ease of operation.
2Ease of operation
If GPS distance measurement method is used, then ease of operation is improved, but measurement precision deteriorates due to error range of several meters
Solution Approach 1:
The patent merges GPS position-based distance calculation with laser direct distance measurement. The GPS provides easy operation and baseline distance information, while the laser provides high-precision verification and correction. The control unit processes both data sources to generate the final distance recommendation, combining the advantages of both methods while mitigating their individual weaknesses.
3Device complexity
If wind characteristics are not considered, then device complexity is reduced, but shot accuracy deteriorates due to wind affecting the shot
Solution Approach 1:
The patent introduces a wind characteristic measurement unit as an intermediary component that measures wind speed and direction. This unit acts as a mediator between the distance measurement system and the shot execution, providing wind correction data that allows the golfer to adjust for wind effects. The control unit processes wind data along with distance data to generate accurate distance recommendations, maintaining reliability while adding only the necessary complexity for wind compensation.

AI summary
A recommended distance provision method for providing a recommended distance in consideration of characteristics of wind by a distance recommendation device for golf is proposed. The method includes calculating a horizontal distance, a vertical distance, and the recommended distance of a shot, which are distances to a target without considering an influence of the wind, on the basis of measurement information including a straight-line distance to the target and an inclination to the target, calculating a horizontal distance correction value for the horizontal distance on the basis of information on a wind direction and a wind speed, calculating an adjusted landing angle for a preset landing angle on the basis of the information on the wind direction and the wind speed, and calculating an additional distance correction value, and calculating a final recommended distance by adding the calculated additional distance correction value and the horizontal distance correction value.
