Distance Measuring Apparatus for Golf Attack Distance Calculation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Golfers face challenges in accurately determining the attack distance to a target point, especially when the target is at a different height or obstructed by obstacles, as existing distance measuring apparatuses do not account for altitude differences and obstacles effectively.
Innovation Solution
A distance measuring apparatus equipped with a display unit, sound output unit, location acquiring sensor, slope sensor, and control unit that calculates the attack distance by using the tilt angle, straight line distance, and landing angle, and compensates for altitude differences using map information, allowing for accurate determination of the attack distance even over obstacles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional distance measuring apparatus is used to measure the straight line distance to the target, then the measurement function is simple, but the attack distance cannot be accurately determined when the target is at a different altitude
Solution Approach 1:
The patent combines multiple sensor functions (distance measuring sensor, slope sensor, location acquiring sensor) and integration with map data into a single distance measuring apparatus. The control unit integrates these diverse data sources to calculate attack distance, merging measurement and calculation functions into one device that accurately determines attack distance despite altitude differences.
Solution Approach 2:
The patent introduces map information as an intermediary element that contains altitude data of the target point. The control unit uses this intermediate map data to adjust the attack distance calculation, mediating between the raw sensor measurements and the final accurate attack distance determination, thereby resolving the altitude difference problem.
2Measurement precision
If the golfer guesses the attack distance based on measured straight line distance, then the operation is simple, but the accuracy is insufficient when obstacles are present
Solution Approach 1:
The distance measuring apparatus performs self-service by automatically calculating the attack distance using its integrated sensors and map data. The control unit autonomously processes the measurement data, applies the appropriate calculations considering altitude differences and obstacles, and provides the accurate attack distance without requiring manual intervention or complex user calculations, thus maintaining ease of operation while improving precision.
3Adaptability or versatility
If the distance measuring apparatus only measures straight line distance, then the measurement function is simple, but it cannot determine attack distance over obstacles or to elevated targets
Solution Approach 1:
The patent enhances the universality of the distance measuring apparatus by enabling it to perform multiple functions: measuring straight line distance, determining altitude differences, calculating attack distance, and accommodating various target conditions (elevated targets, obstacles). The control unit processes different measurement scenarios and provides appropriate attack distance calculations for diverse golfing situations, making the device universally applicable to all target conditions without requiring separate specialized equipment.
