Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current basketball training systems lack the ability to efficiently and seamlessly provide a steady supply of balls to athletes in various positions on the court, fail to distinguish between different ball sizes, and do not integrate with standard courts to enhance training efficiency and fun, often requiring manual intervention and delivering unnatural passes.
Innovation Solution
A ball return system integrated with a playing surface that includes a ball return mechanism with a movable passing device, optical sensors, and a system controller to automatically manipulate the passing device based on real-time player data, providing varied passes such as chest, bounce, and lob passes, and accommodating different ball sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed location passing machine is used under the hoop, then ball capture is effective, but passing ability is limited to a single position
Solution Approach 1:
The passing machine is transformed from a fixed static structure to a dynamic mobile platform equipped with caster wheels, allowing it to move to different positions on the court while maintaining its ball capture and passing functions
Solution Approach 2:
The machine integrates multiple functions: ball capture, storage, and passing delivery in a single mobile unit that can serve multiple positions on the court, making it adaptable to different training scenarios
2Adaptability or versatility
If manual rolling of passing machines is implemented, then repositioning is possible, but additional labor from assistants is required
Solution Approach 1:
The passing machine is equipped with autonomous navigation capabilities including sensors, processors, and control systems that enable it to move and position itself automatically without human assistance, performing its own repositioning service
3Speed
If punching or catapulting mechanisms are used to launch balls, then ball delivery is achieved, but spin is not applied resulting in wobbly trajectory
Solution Approach 1:
The mechanical punching or catapulting mechanism is replaced with a pneumatic or hydraulic launching system that provides controlled force application, enabling both speed generation and spin imposition for stable ball trajectory
Solution Approach 2:
The ball launching parameters are optimized by adjusting force magnitude, application point, and duration to achieve the desired combination of speed and spin, transforming the trajectory stability through parameter control
4Force
If manual passing-force adjustments via spring tension are used, then passing force control is achieved, but athlete must be in narrow range of positions to catch the ball
Solution Approach 1:
The static spring tension mechanism is replaced with a dynamic force control system that can adjust passing force in real-time based on detected athlete position, enabling force adaptation to a wider range of catching positions
Solution Approach 2:
Sensors detect the athlete's position and the system uses this feedback to automatically adjust the passing force and trajectory parameters, creating a closed-loop control system that maintains accurate ball delivery across various positions
5Shape
If passing machines sit low to the ground delivering chest passes, then arc-shaped trajectory is achieved, but the pass appears unnatural
Solution Approach 1:
The machine's operational parameters including launch height, angle, and force are dynamically adjusted to vary the ball trajectory shape, enabling delivery of different pass types (chest pass, bounce pass, overhead pass) that appear more natural
6Extent of automation
If current passing machines are used, then basic repositioning is possible, but programming and software remain limited
Solution Approach 1:
Basic mechanical repositioning controls are replaced with an advanced software system featuring sensors, processors, and algorithms that enable intelligent autonomous navigation, player recognition, and adaptive passing behavior
Solution Approach 2:
The software system integrates multiple functions including player detection, position tracking, pass type selection, force control, and autonomous navigation in a single integrated control platform, expanding capability beyond basic repositioning
7Ease of operation
If passing machines cannot distinguish between ball sizes, then simple operation is maintained, but players must take turns depending on which ball is loaded
Solution Approach 1:
The machine is equipped with sensors and recognition systems that automatically detect and identify different ball sizes, and autonomously selects and loads the appropriate ball type without human intervention, maintaining simple operation while enabling continuous training
Solution Approach 2:
The system uses optical sensors to detect ball size characteristics, provides feedback to the control system, which then automatically adjusts loading and passing parameters to accommodate the specific ball type, enabling seamless handling of multiple ball sizes

AI summary
A ball return system is integrated with a playing surface upon which a player trains, and includes a ball storage mechanism, ball passing device, and a track structure. The storage mechanism has one or more ball transport mechanisms, ball sorting mechanisms, ball storage groups, and a ball release mechanism. The ball passing device is configured to accept expelled balls from the release mechanism, and to pivot via panning and tilting. The track structure has lateral and vertical motion mechanisms and is configured to raise and lower the lateral motion mechanism. The ball return system also includes optical sensors to capture visual data from player characteristics, location, and movements and a system controller that receives data from the optical sensors and is in two-way communication with a plurality of sub-controllers for passing, lateral motion, vertical motion, and ball release.
