Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If golfers practice on a course or range, then they can view ball trajectory feedback, but the practice is limited by weather conditions and facility access
Solution Approach 1:
The system creates a virtual copy of the golf course environment and ball trajectory visualization. Instead of requiring physical presence on a course, the system generates a simulated golf course layout with virtual representations of balls, trajectories, and course features. This virtual copy can be accessed anywhere without weather or facility restrictions while providing the same training feedback.
Solution Approach 2:
The system replaces the mechanical requirement of physical ball trajectory observation with electronic/optical sensing and display systems. Sensors track the actual ball trajectory, and a display device presents this information graphically. This substitution eliminates the need for the golfer to physically observe trajectories in real-time on a course, allowing practice in any weather conditions.
2Loss of information
If golfers simply view ball trajectory in the real world during field practice, then they can observe shot outcomes, but this provides limited feedback for correcting technique
Solution Approach 1:
The system implements comprehensive feedback mechanisms that automatically capture ball trajectory data, club head speed, launch angle, and other technical parameters. The system then presents this information through graphical displays, audio cues, and virtual overlays that provide immediate, quantifiable feedback on technique. This structured feedback loop enables golfers to identify and correct specific technical issues more effectively than simple visual observation.
Solution Approach 2:
The system introduces an intermediary layer between the golfer and the ball trajectory. Instead of directly observing the ball flight, the golfer receives processed information through sensors, displays, and audio feedback. This intermediary system translates complex physical trajectory data into actionable insights, making the feedback more useful for technique correction while maintaining ease of operation.
3Loss of information
If golfers practice without statistical information, then they can focus on immediate shot execution, but they lack data to compare performance against past shots and others
Solution Approach 1:
The system performs preliminary data collection and processing before the golfer needs to analyze performance. Sensors continuously track trajectory parameters, and the system pre-processes this data to generate statistical summaries, comparisons to past shots, and performance benchmarks. This preliminary action ensures that when the golfer views the feedback, comprehensive statistical information is already ready, eliminating the need for complex real-time analysis while providing rich data insights.
4Measurement precision
If golfers use traditional practice methods, then they can maintain simple equipment, but they cannot accurately observe ball trajectory with the naked eye
Solution Approach 1:
The system replaces the human eye's limited trajectory observation capability with electronic sensing and display systems. Sensors positioned at multiple locations track the ball's position, speed, and trajectory in three-dimensional space. This mechanical/optical substitution provides precise measurement of trajectory parameters that are difficult or impossible to accurately observe with the naked eye, while the system manages the complexity of the tracking equipment through automated data processing and presentation.

AI summary
A mixed-reality golf simulation system includes a ball-tracking sub-system to generate ball-tracking data when a golf ball is hit by a user, a near-eye display, a storage device to store panoramic images of a hole of a golf course associated with location coordinates of a plurality of locations along the hole, and a controller. The controller may direct the near-eye display to display a mixed-reality environment including a virtual reality scene from the perspective of a first location on the hole over based on images associated with location coordinates of the first location, receive ball-tracking data of a ball hit by the user in real-time, and direct the near-eye display to display the mixed-reality environment including a virtual reality scene from the perspective of a landing location of the ball based on images device associated with location coordinates of the landing location of the ball.
