Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a virtual golf simulation is displayed on a screen, then golfers can play golf at low cost in downtown areas, but the trajectory of the ball in the real world does not match the trajectory displayed in the simulation area, resulting in lack of sense of reality

Engineering Contradiction:
Improveaccessibility of virtual golfVSAvoidsense of reality
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent uses a camera to capture the actual trajectory of the golf ball in the real world and displays this captured trajectory on the screen in the simulation area. This copying approach allows the virtual display to accurately reflect the real-world ball motion, creating a matching trajectory between reality and simulation that enhances the sense of reality while maintaining accessibility

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The system continuously captures the golf ball's trajectory using a camera and updates the display in real-time. This feedback loop ensures that the simulation area shows the actual ball path, creating a synchronized experience between the physical golf swing and its visual representation, thereby improving immersion and realism

Inventive Principle:
Principle #23Feedback

2Reliability

If the trajectory in the real world is captured and displayed in the simulation area, then the sense of reality and immersion is improved, but the system complexity increases due to additional photographing modules and coordinate synchronization

Engineering Contradiction:
Improvesense of realityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces a camera as an intermediary device between the real-world golf ball and the display screen. This camera captures the ball's trajectory and provides this information to the display system, serving as a mediator that bridges the physical and virtual domains. This intermediary approach simplifies the overall system architecture by using a single dedicated capture device rather than complex multi-sensor arrays

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces complex mechanical trajectory measurement systems with an optical capture approach using a camera. Instead of using mechanical sensors, encoders, or complex coordinate transformation systems, the invention uses visual capture to track the ball's path, substituting mechanical measurement with optical detection and image processing, thereby reducing mechanical complexity

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A method for supporting a virtual golf simulation is provided. The method includes the steps of: determining, with reference to information on a first reference pattern specified in an image photographed by a first photographing module positioned to photograph a moving subject and information on a second reference pattern specified in an image photographed by a second photographing module positioned to photograph a display area where information associated with the subject is displayed, a positional relationship between coordinates specified in the first photographing module and coordinates specified in the display area; and determining information on a trajectory of the subject in the display area with reference to the positional relationship.
