Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual golf systems cannot implement extreme golf in indoor spaces effectively, as they fail to accurately reflect the time required to move to the hole-in in the scoring process.
Innovation Solution
A virtual extreme golf system that includes a sensing means to measure a user's step and generate swing information, a control means with a DB unit storing course information, a position change unit, and a time calculation unit to calculate movement time using step information and stride, allowing for accurate scoring based on both number of strokes and movement time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional virtual golf systems are used, then the system is simple to operate, but extreme golf cannot be implemented accurately because movement time is not reflected in scoring
Solution Approach 1:
The system segments the golf game into distinct phases (walking to ball position, swinging, ball movement) and measures each phase separately using different sensors. The sensing means is divided into step detection units and swing detection units, allowing precise measurement of movement time and swing characteristics independently, which resolves the contradiction by enabling accurate extreme golf scoring without requiring a completely complex system overhaul.
Solution Approach 2:
The patent introduces an intermediary computing device that processes data from simple sensors (step counter, accelerometer) and calculates movement time and swing metrics. This intermediary layer transforms basic sensor inputs into meaningful game metrics, enabling accurate extreme golf scoring while keeping the actual sensing hardware relatively simple and easy to operate.
2Area of stationary object
If indoor space is limited, then space constraints increase, but extreme golf requires sufficient space for movement
Solution Approach 1:
The system transitions from requiring physical space for actual golf swing motion to measuring swing characteristics through sensors attached to the club. The swing detection unit captures angular velocity and acceleration data, allowing the game to be played in a compact indoor space while maintaining the essence of extreme golf through virtual ball movement and scoring based on measured swing parameters.
Solution Approach 2:
The patent creates a virtual copy of the golf course and ball movement that can be displayed on a screen within limited indoor space. Instead of requiring physical movement across a real course, the system copies the golf experience through visual display and sensor-based swing detection, enabling extreme golf gameplay in confined spaces while maintaining gameplay flexibility.
3Measurement precision
If movement time is not measured, then the scoring system is simple, but extreme golf cannot be accurately reflected
Solution Approach 1:
The step detection unit utilizes the golf club itself as the sensing element, detecting steps through the natural up-and-down motion of the club during the golfer's walk. This self-service approach eliminates the need for separate wearable step counters or complex motion capture systems, making movement time measurement accurate yet relatively simple to implement.
Solution Approach 2:
The patent replaces complex mechanical movement time measurement systems with electronic sensors that detect club motion and automatically calculate movement time. The accelerometer and processing unit substitute for manual timing or complex mechanical chronometers, making the measurement process both more precise and easier to implement in the extreme golf system.
