Soccer Ball Shot Control Using Time-Based Speed-Angle Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soccer games limit the variety of shots that can be executed with a single command, requiring skill to adjust angle and speed, and lack the ability to reproduce different types of shots with varying angle-speed relations.
Innovation Solution
A computer program that allows the movement speed and climb angle of a ball to be determined based on the duration of a single command, using different rules for each shot type, enabling more diverse shot execution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single speed command is used to control both movement speed and climb angle of the ball, then the operation becomes simpler and shots can be reproduced easily, but the variety of shot types is limited and angle-speed relations cannot be varied
Solution Approach 1:
The patent applies dynamics by making the relationship between operation duration and ball parameters dynamic rather than fixed. The system automatically adjusts the climb angle and movement speed based on the duration of the speed command, allowing the same operation input to produce different shot types with varying angle-speed relations. This resolves the contradiction by enabling shot variety without requiring complex multi-button operations.
Solution Approach 2:
The patent changes the parameters of the ball trajectory (climb angle and movement speed) based on the duration parameter of the speed command. By varying these parameters dynamically according to how long the player holds the button, the system enables multiple shot types (e.g., lob shots, driven shots, semi-volleys) to be executed through a single command mechanism, thus maintaining operational simplicity while increasing shot variety.
2Adaptability or versatility
If multiple buttons are used to control different shot parameters, then shot variety increases, but the operation becomes more complex and requires higher skill to execute consistently
Solution Approach 1:
The patent makes the single speed command button universal by enabling it to control multiple shot parameters (both movement speed and climb angle) simultaneously. Instead of requiring separate buttons for each parameter, the duration of this single button press determines both the power and trajectory angle of the shot. This multi-functionality approach allows players to access various shot types through one standardized operation, reducing complexity while maintaining shot variety.
3Manufacturing precision
If button press strength determines shot speed and angle, then shot control precision increases, but delicate adjustment skill is required and reproducing the same shot becomes difficult
Solution Approach 1:
The patent replaces the mechanical pressure-based control system with a time-based control system. Instead of measuring how hard the player presses the button (which requires delicate tactile skill), the system measures how long the button is held down. This substitution transforms the control mechanism from force-sensitive to time-sensitive, making shot reproduction more consistent and easier to execute precisely without requiring advanced tactile adjustment skills.

AI summary
A non-transitory computer readable storage medium according to the present invention stores a computer program causing a control unit of a game device, which provides a soccer game that includes a normal shot that follows a rule that the movement speed and climb angle of a ball increase according to the duration of an operation of a left operation button of a controller, to function as the following device. That is, the computer program causes the control unit to function as a device that, when an R2 button of the controller has been pressed, decides, according to the duration of the operation of the left operation button, the movement speed and climb angle of the ball in accordance with a rule which differs from that of the normal shot, and controlling display so that the ball moves at the decided movement speed and the like, as a power shot of a kind similar to the normal shot.
