Volleyball Training Device Angle Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional volleyball passing training devices have limited functionality, allowing only height adjustment of the ball hoop, which restricts training effectiveness and fails to accommodate practice at various angles, thereby limiting player improvement.
Innovation Solution
A volleyball passing training device incorporating an angle adjustment mechanism with a connecting piece, first and second connecting rods, and a sliding device that allows the ball hoop to be adjusted to different angles, combined with a lifting mechanism for height adjustment and a collection mechanism to manage ball accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If only height adjustment of the ball hoop is provided, then the device structure is simple, but the training function is single and cannot accommodate practice at various angles
Solution Approach 1:
The ball hoop is made movable in both height and angle through a dynamic adjustment mechanism. The connecting rod with sliding block allows the ball hoop to change its angle relative to the vertical direction, while the telescopic rod enables height adjustment. This dynamic structure transforms a static single-function device into a multi-functional training apparatus that can accommodate various practicing angles.
Solution Approach 2:
The training device is designed to perform multiple training functions by adjusting the ball hoop to different angles and heights. It can support front serving practice, side serving practice, and other angular variations, making it a universal training apparatus that replaces multiple separate training devices.
2Productivity
If multiple persons are required for service to form a multi-ball cycle exercise, then the training can be conducted, but the device complexity and space requirements increase
Solution Approach 1:
The training device incorporates a ball collection mechanism that automatically collects balls after they pass through the ball hoop. This self-service feature eliminates the need for multiple persons to manually retrieve and reset balls, allowing a single practitioner to conduct efficient multi-ball cycle exercises independently.
Solution Approach 2:
The ball collection mechanism acts as an intermediary between the ball hoop and the practitioner. It automatically receives balls from the hoop and stores them, eliminating the need for human intervention in ball retrieval and resetting, thereby improving training efficiency.
3Adaptability or versatility
If the ball hoop is fixed at a specific height and angle, then the device structure is simple, but the training effect is limited and cannot accommodate different practicing angles
Solution Approach 1:
The ball hoop is equipped with a dynamic adjustment mechanism consisting of a connecting rod and sliding block that allows the hoop to be positioned at various angles relative to the vertical direction. This dynamic structure enables the same device to accommodate different practicing angles without requiring multiple fixed-position devices.
Solution Approach 2:
The device enables parameter changes in both the angular orientation and height of the ball hoop. By changing these parameters through the adjustment mechanisms, the device can adapt to different training requirements and practicing angles, transforming a fixed-parameter device into a variable-parameter training apparatus.

AI summary
The present disclosure discloses a volleyball passing training device, which includes an angle adjustment mechanism and a ball hoop arranged on the angle adjustment mechanism. The angle adjustment mechanism includes a connecting piece connected to the ball hoop, and a first connecting rod and a second connecting rod respectively hinged to the connecting piece. A sliding device which can slide or fix on the second connecting rod is arranged on the second connecting rod. The first connecting rod is hinged to the sliding device. Connecting lines of the hinge points between the first connecting rod and the connecting piece and between the second connecting rod and the connecting piece and the hinge point between the first connecting rod and the sliding device form a triangle.
