Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing virtual golf systems fail to provide accurate and intuitive putting information to users, making it difficult to assess terrain characteristics and execute successful putts due to the disparity between the screen display and the actual playing surface.

Innovation Solution

A virtual golf device and system that includes a hitting mat with an image providing means to display a swing trajectory image, which incorporates a moving golf club or guider to represent putting direction and force information, and provides this information on the same plane as the user's putting surface, enhancing user convenience and skill improvement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If putting information is displayed on a screen separate from the hitting surface, then users can view putting guidance, but users experience difficulty aligning their swing with the displayed trajectory due to the disparity between screen display and actual playing surface

Engineering Contradiction:

Improveputting information deliveryVSAvoidswing alignment accuracy

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The patent combines the information display function with the hitting surface by projecting the swing trajectory image directly onto the hitting mat or a surface adjacent to it. This merging of the display medium with the interaction surface eliminates the spatial separation between information presentation and physical action, allowing users to align their swings accurately with the displayed trajectory without the disorientation caused by separate screen display.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces a projection system as an intermediary medium that bridges the gap between the digital information (swing trajectory data) and the physical playing surface. By projecting the trajectory image onto the hitting surface, the projection system serves as a mediator that translates abstract numerical or graphical data into a visual guide directly visible at the point of interaction, resolving the conflict between information delivery and operational accuracy.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If detailed putting information is provided to help users assess terrain characteristics, then putting skill improvement is enabled, but the device complexity increases

Engineering Contradiction:

Improveterrain assessment accuracyVSAvoidinformation processing capability

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical or computational analysis systems with a visual projection system. Instead of requiring users to interpret numerical data or complex graphical interfaces, the system projects a simplified visual representation of the swing trajectory that inherently encodes terrain characteristics. This substitution maintains high measurement precision for terrain assessment while significantly reducing device complexity by using optical projection rather than complex computational displays.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
