Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If various image production methods and advanced sensors are used to represent ball trajectory, then the trajectory visualization is improved, but the ability to intuitively provide detailed shot data such as speed and travel direction in the rising zone is insufficient

Engineering Contradiction:

Improvetrajectory visualizationVSAvoiddetailed shot data

Core Design Contradiction:

Illumination intensityVSLoss of information

Solution Approach 1:

The patent divides the ball trajectory into multiple zones (rising zone, apex zone, descending zone) and applies different visualization methods to each zone. Specifically, the rising zone is highlighted with enhanced visual indicators showing launch angle and directional angle, while other zones display standard trajectory information. This segmentation allows detailed shot data to be prominently displayed where most needed without overwhelming the entire visualization.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent adds angular dimension information (launch angle and directional angle) to the traditional two-dimensional trajectory visualization. By representing the ball's motion in three-dimensional space with angular components, the system provides intuitive visual feedback about shot direction and angle without complicating the display. This dimensional enhancement transforms abstract trajectory data into visually comprehensible angular measurements.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Shape

If focus is put on representing ball trajectory as a parabola, then the overall flight path is visualized, but the ability to identify launch angle and directional angle in the rising zone is limited

Engineering Contradiction:

Improveparabola trajectoryVSAvoidlaunch angle and directional angle identification

Core Design Contradiction:

ShapeVSMeasurement precision

Solution Approach 1:

The patent applies different levels of detail and visualization quality to different parts of the trajectory. The rising zone receives enhanced visual treatment with prominent display of launch angle and directional angle measurements, while the apex and descending zones use standard visualization. This local quality enhancement ensures that critical measurement information is precisely displayed where it matters most for shot analysis.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent uses color coding to differentiate trajectory zones and highlight important measurement information. The rising zone is displayed with distinct coloring to draw attention to launch angle and directional angle data, while other zones use different colors or shading. This color differentiation helps users quickly identify and interpret angular measurements without confusion.

Inventive Principle:

Principle #32Color changes

3Adaptability or versatility

If screen golf systems provide basic trajectory simulation, then users can play golf indoors, but user immersion and golf skill enhancement are limited due to lack of intuitive shot data

Engineering Contradiction:

Improveindoor golf capabilityVSAvoiduser immersion and skill enhancement

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent implements immediate visual feedback by displaying launch angle and directional angle information directly on the trajectory visualization during or immediately after the swing. This real-time feedback allows users to understand the relationship between their swing mechanics and ball flight characteristics, enabling skill enhancement through intuitive visual information rather than requiring complex data interpretation.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent introduces visual intermediaries (angular measurement indicators, zone markers, and trajectory overlays) that mediate between the raw sensor data and the user's understanding. These visual intermediaries translate complex trajectory data into intuitive angular measurements and zone-based visualizations, making the system easier to use and more immersive without requiring users to understand underlying physics or data processing.

Inventive Principle:

Principle #24Intermediary (Mediator)
