Volleyball Training Device With Adjustable Net Lattice
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current training devices for volleyball spiking lack the ability to effectively simulate the experience of spiking a volleyball, particularly in terms of net interaction and adjustable height settings, which are crucial for realistic practice.
Innovation Solution
A training device comprising a base with vertically extensible nested rods, a coupler for positioning a volleyball, and a lattice that can be positioned between the base and the coupler to simulate a volleyball net, allowing for adjustable height settings and realistic spiking practice.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-height training device is used, then the device structure is simple, but the adaptability to different training needs is poor
Solution Approach 1:
The patent applies the dynamics principle by implementing adjustable height mechanisms that allow the training device to change its configuration. The height-adjustable backrest and seat, along with the extendable arm support, enable the device to adapt to different user sizes and training requirements, transforming a static structure into a dynamic one that can be reconfigured based on needs.
Solution Approach 2:
The patent employs parameter changes by allowing modification of key dimensional parameters such as backrest height, seat height, and arm support extension distance. These adjustable parameters enable the same device to serve multiple training purposes and accommodate different users without requiring multiple fixed-height devices.
2Reliability
If a training device without net simulation is used, then the device structure is simple, but the realism of spiking practice is insufficient
Solution Approach 1:
The patent applies the copying principle by incorporating a net simulation element that replicates the appearance and function of a real volleyball net. This net structure is positioned between the arm support and the volleyball, creating a visual and physical copy of the actual playing condition, which enhances the realism of the spiking practice without requiring a full-sized real net.
3Reliability
If an adjustable arm support device is used, then the training effectiveness is improved, but the ease of operation is reduced
Solution Approach 1:
The patent applies dynamics by implementing smooth adjustment mechanisms for the arm support extension distance. The adjustable design allows users to easily modify the arm support position during training sessions, making the dynamic adaptation straightforward and maintaining ease of operation despite the added functionality.

AI summary
A volleyball training device for practicing spiking of a volleyball includes a base that is configured to position on a substantially horizontal surface. A plurality of nested rods, which is selectively vertically extensible, is coupled to and extends perpendicularly from a first end of the base. A first rod is coupled to and extends perpendicularly from an upper end of the nested rods. The first rod is opposed to the base. A coupler is coupled to and extends downwardly from the first rod distal from the nested rods. A lattice is selectively couplable to and extends from the plurality of nested rods. The lattice is selectively positionable between the base and the coupler. The coupler is configured to selectively couple to a volleyball to position the volleyball to be spiked by a user. The lattice is configured to simulate a volleyball net.
