Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional soccer ball kicking training devices restrict user training to specific positions, limiting the ability to practice kicking techniques with the middle part of the instep and suffer from a restricted joint area that can cause safety risks and hinder smooth ball rotation, failing to simulate actual game scenarios effectively.
Innovation Solution
A soccer ball kicking training device with a hinge mechanism that allows the arm and attached ball to pivot and rotate freely, adjustable to various heights and angles, incorporating an anti-pinch slider to prevent user injury, and enabling the ball to simulate spinning motion, thus enhancing training realism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the joint area between the bracket or socket and the rod is restricted by the inner diameter of the hole for insertion of the rod, then the structure is simplified, but the movement range of the rod is relatively small and the rod cannot move smoothly during rotation
Solution Approach 1:
The joint area is divided into two separate components: the rod with its hole and the bracket or socket. This segmentation allows the rod to rotate smoothly within the bracket without being constrained by the inner diameter of the hole, thereby increasing the movement range while maintaining structural simplicity through modular design.
Solution Approach 2:
The joint area is designed to be dynamic rather than fixed. The rod can rotate freely within the bracket, and the entire arm can pivot at various angles. This dynamic design enables smooth movement during rotation and allows the ball to simulate actual spinning motion, resolving the contradiction between structural simplicity and operational flexibility.
2Device complexity
If the joint area is restricted by the inner diameter of the hole, then the structure is simpler, but additional differences compared with actual field training occur, causing a detrimental impact on the training effort
Solution Approach 1:
The joint area is designed to be dynamic rather than fixed. The rod can rotate freely within the bracket, and the entire arm can pivot at various angles. This dynamic design enables smooth movement during rotation and allows the ball to simulate actual spinning motion, resolving the contradiction between structural simplicity and operational flexibility.
3Device complexity
If the members connecting with and supporting the balls are generally fixedly attached or positioned on the base, then the device structure is simplified, but the users can only be trained in the positions strictly restricted by the mechanical operation of the device
Solution Approach 1:
The arm is designed with multiple degrees of freedom, allowing it to pivot at various angles and rotate freely. This dynamic design enables the ball to be positioned at multiple locations and orientations, providing training flexibility while maintaining structural simplicity through the use of a single arm component that can perform multiple functions.
Solution Approach 2:
The arm serves multiple functions: it can be positioned at various angles, rotated to different orientations, and used for different kicking techniques. This multi-functionality allows a single structural component to provide versatile training capabilities, resolving the contradiction between structural simplicity and training position flexibility.
4Ease of operation
If the rod is rotatably mounted in the hole of the rod, then the ball can rotate, but the joint area is exposed and may pinch the user presenting a possible safety risk
Solution Approach 1:
A cover is introduced as an intermediary component that encloses the joint area between the rod and bracket. This cover protects the user from pinching hazards while allowing the rod to rotate freely within the bracket, thereby maintaining ball rotation capability while eliminating the safety risk associated with exposed joint areas.

Implementation Method 1
The hinge mechanism (21) supports the arm (9) for pivotal movement about a substantially horizontal, third axis (23) relative to the upright column (5) and the first axis (7)
Implementation Method 2
The arm (9) further has a rotational mechanism (25) for permitting the first end portion (13) of the arm (9) with the ball (17) attached to it to rotate relative to the second end portion (15) about the arm's second axis (11)
