Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional sports training equipment, such as tennis training devices, are bulky, difficult to transport, and lack features to provide feedback on training processes and results, leading to decreased user engagement and ineffective training experiences.
Innovation Solution
A tennis training device with a separable batting and rebounding net component, utilizing lightweight materials and a folding structure, equipped with LED lighting, a controller, microphone, and camera to provide real-time feedback and analysis through a mobile application, enhancing user interaction and training interest.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional tennis training equipment is used, then training functionality is provided, but the device is bulky and difficult to transport
Solution Approach 1:
The tennis training device is divided into separate modules: a rebounding net component and a batting component. The rebounding net component includes a supporting rod and rebounding net plate, while the batting component includes an adjustable bracket group and batting cloth. These components can be assembled or disassembled, allowing the device to be transported in parts and reducing the weight burden during transportation while maintaining full functionality when assembled.
Solution Approach 2:
The bracket group employs telescopic frames with telescopic nodes that allow dynamic adjustment of frame length. The diameters of the telescopic frames are gradually decreased so that frames at each telescopic node can be accommodated within nodes below, enabling compact storage and easy transportation while providing adjustable dimensions during use.
2Loss of information
If traditional tennis training equipment is used, then basic training is possible, but it provides no feedback on training process and results
Solution Approach 1:
The device incorporates a controller connected to a microphone and LED lamp that provide real-time feedback during training. The microphone captures sound, and the LED lamp provides visual feedback, allowing users to connect their training effects and improve training interest through immediate response information about their performance.
Solution Approach 2:
The controller integrates multiple functions: it processes audio input from the microphone, controls LED lighting feedback, and can interface with mobile applications for data analysis. This multi-functional integration provides comprehensive training feedback without requiring multiple separate devices, balancing enhanced functionality with manageable system complexity.
3Ease of operation
If lightweight materials and folding structures are used, then portability is improved, but structural strength may be compromised
Solution Approach 1:
The device utilizes composite construction in its bracket group, combining telescopic frames with nodes that provide structural reinforcement. The framework employs graduated diameter design where larger diameter sections provide strength while smaller diameter sections reduce weight, creating an optimized composite structure that balances portability with structural integrity throughout the bracket assembly.
Solution Approach 2:
The telescopic frames are designed with nested accommodation where frames at each telescopic node can be stored within nodes below. This nesting arrangement allows the structure to collapse into a compact form for easy transportation while maintaining full structural strength when extended and assembled for use.
