Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing juggling devices for soccer balls restrict the ball's movement, causing it to return to its starting point and requiring players to retrieve it frequently, wasting training time and hindering effective practice.

Innovation Solution

A device with a ball-holding mechanism attached to a rod that allows 360° rotation and tilting, featuring a height-adjustable base and optional counterweight, ensuring the ball moves freely while being securely held, mimicking natural juggling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If the ball is securely held to prevent it from bouncing away, then training time is saved, but the ball's natural movement is restricted

Engineering Contradiction:

Improvetraining timeVSAvoidball movement freedom

Core Design Contradiction:

Loss of timeVSEase of operation

Solution Approach 1:

The device employs a ball joint that enables dynamic movement of the rod in multiple directions (360° rotation and tilting), allowing the ball to move naturally during juggling exercises while remaining securely attached. This dynamic connection resolves the contradiction by maintaining both security and freedom of movement.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The ball joint changes the parameters of movement freedom by allowing rotation through 360° and tilting in at least one plane, transforming the ball's motion from restricted to natural while maintaining attachment security.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If the ball is attached to a rigid structure, then the ball returns to starting point automatically, but the exercise becomes less realistic and requires frequent retrieval

Engineering Contradiction:

Improveball return to starting pointVSAvoidtraining efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The ball joint creates a dynamic connection that prevents automatic return to the starting point while maintaining reliable attachment. The rod can rotate and tilt freely, allowing the ball to move naturally during juggling without being pulled back, thus improving training efficiency.

Inventive Principle:

Principle #15Dynamics

3Ease of operation

If the rod is made longer to increase movement range, then realistic juggling simulation improves, but device stability decreases

Engineering Contradiction:

Improvemovement rangeVSAvoiddevice stability

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

A counterweight can be attached to the rod to compensate for the increased leverage and instability caused by the longer rod length. This maintains device stability while preserving the extended movement range needed for realistic juggling simulation.

Inventive Principle:

Principle #8Anti-weight (Counterweight)

AI summary

A device (1) for performing juggling exercises with a soccer ball (2) comprises a ball-holding device (3) to which the soccer ball (2) can be attached, a rod (4) at one end of which the ball-holding device (3) is attached, a joint (5) to which the rod (4) is attached, a retaining element (6) for holding the joint (5), and a base (7) for receiving the retaining element (6). The joint (5) is designed as a ball joint. The rod (4) is attached to the ball joint such that the rod (4) can rotate continuously through 360° and tilt in at least one plane. The retaining element (6) is height-adjustable relative to the base (7).
