Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf rangefinders, such as GPS and laser rangefinders, face challenges in accuracy due to user operation and lack of aids on golf courses, particularly in determining the precise distance to targets like flagsticks without reflectors, leading to impractical use.
Innovation Solution
A distance detector incorporating a laser transmitter and receiver, an image detection system with a digital display showing a real-time image and laser beam indicium, and a range-finding system that calculates and displays the distance to overlapping objects, including a feature detector to identify and lock onto preselected targets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a laser rangefinder is used to measure distance to objects on a golf course, then the device can provide distance measurements without GPS coordinates, but the accuracy is vulnerable to user operation and lack of target locking aids
Solution Approach 1:
The patent displays the laser beam position on a digital display to provide visual feedback to the user, allowing them to see where the laser is pointing and adjust aiming accordingly. This feedback mechanism resolves the contradiction by enabling accurate distance measurements without requiring expert user skill, as the system guides the user through visual confirmation of laser alignment with the target
Solution Approach 2:
The patent introduces a digital display as an intermediary between the laser beam and the user's perception. The display shows the laser beam position and target alignment, acting as a mediator that translates the invisible laser beam into visible information. This intermediary resolves the contradiction by providing target locking aids that eliminate user operation difficulties while maintaining measurement precision
2Adaptability or versatility
If the laser beam is aimed at multiple objects, then the device can measure distances to various targets, but it becomes difficult to determine which distance measurement is the correct one to display
Solution Approach 1:
The patent displays the positions of multiple objects and the laser beam on a digital display, providing visual feedback that shows which object the laser is currently aligned with. This feedback allows the system to maintain multi-object measurement capability while preventing information loss about target identification, as the user can see which object corresponds to the displayed distance measurement
Solution Approach 2:
The patent segments the display into distinct visual elements showing different objects and the laser beam position separately. By segmenting the visual information, the system can present multiple target options while clearly indicating which one is currently selected for measurement, resolving the contradiction between versatility and information clarity
