Soccer Set Piece Simulation System for Indoor Kick Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current soccer training simulations indoors lack the capability to effectively practice strong and sophisticated kicks due to limitations in space and the need for precise calculations considering various physical variables, unlike other sports like golf or baseball, which makes it difficult to replicate the actual set piece situations in soccer.
Innovation Solution
A set piece simulation system that includes a data transmission/reception unit, image output unit, kick information analysis unit, and image processing unit to analyze and display the soccer ball's trajectory, speed, and spin, incorporating environmental conditions and coaching information, using a sensing device, image capturing device, and room condition control, to provide a realistic simulation environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If indoor soccer training is conducted in limited space, then training accessibility is improved, but the ability to practice strong and sophisticated kicks deteriorates
Solution Approach 1:
The patent creates a virtual copy of the outdoor soccer field environment through a large-screen display system. The screen displays a simulated soccer field with goalposts, goalkeeper, and surrounding environment, allowing players to practice kicks in an indoor setting while experiencing the visual feedback of an outdoor field. This copying of the outdoor environment enables players to practice strong and sophisticated kicks without needing actual outdoor space.
Solution Approach 2:
The patent replaces the physical outdoor field with a visual simulation system. Instead of relying on the actual physical space and gravity-based ball trajectory in outdoor conditions, the system uses image processing and visual display to simulate the kicking environment. The system captures the player's kicking motion and displays the simulated ball trajectory and impact, substituting the mechanical physical field with a visual-simulation field.
2Adaptability or versatility
If conventional simulation systems are used for soccer, then game interest is improved, but the ability to simulate set piece situations with multiple physical variables deteriorates
Solution Approach 1:
The patent changes the parameters of the simulation system to accommodate soccer-specific physical variables. Instead of using fixed parameters like in golf or baseball, the system dynamically adjusts parameters including ball mass, ball size, foot shape, leg length, gravity center position, and wind conditions. These parameter changes enable the system to accurately simulate set piece situations while maintaining manageable computational complexity through targeted parameter adjustment rather than exhaustive variable analysis.

AI summary
A set piece simulation system provides a simulation of a set piece in soccer. The system includes a data transmission/reception unit, an image output unit, a kick information analysis unit, and an image processing unit. The data transmission/reception unit receives ball location information from a sensing device, the image output unit outputs a set piece background screen to an image output device, the sensed ball location and auxiliary information including angle(s) based on the ball location, the data transmission/reception unit receives a user's kick motion image and kick information including speed, spin rate, and/or direction of the ball, the kick information analysis unit analyzes movement path of the ball, and the image processing unit displays trajectory of the ball and the speed and spin information of the ball on the set piece background screen based on the analyzed movement path.
