SpringWheel Court Retriever is a working prototype designed to make ball retrieval faster, more ergonomic, and less disruptive to training. Protected by U.S. Utility Patent 11,844,984 B2, it integrates retrieval, storage, and transport in a single system.
A patented spring-assisted retrieval system that transforms tennis ball collection into one fluid, hands-free motion.
U.S. Utility Patent 11,844,984 B2
Functioning proof-of-concept video completed
Retrieval, storage, and transport in one motion
Designed to eliminate repetitive stopping, bending, and manual collection.
SpringWheel Court Retriever turns ball collection into a seamless part of training. Rather than treating retrieval as a separate task, it allows users to move, collect, and continue with less interruption and less strain.1. Hands-Free Retrieval
Collects balls without repeated bending or separate pickup tools.2. Integrated Storage
Balls move directly into the basket as they are collected.3. Smooth Transport
Retrieval and carrying happen in the same system.

Step 1
Roll into position
The cart moves easily across the court toward scattered balls.Step 2
Lower and collect
Compressible wheel supports allow the basket to lower so balls pass through flexible openings built into the basket floor.Step 3
Store and continue
The balls remain contained inside the cart for easy storage and transport.
SpringWheel Court Retriever improves the exact point where utility matters most: the act of collection itself.
Instead of relying on a chute, a separate retrieval tool, or a rigid pickup frame, it uses an integrated spring-wheel architecture that allows the basket to lower to the playing surface so balls pass through flexible openings built into the bottom of the cart.
Retrieval, storage, and transport happen in one continuous action.
Integrated spring-wheel architecture
Retrieval, storage, and transport in one system
Less bending and less interruption
More efficient training flow
Cleaner mechanical design than conventional ball pickers
SpringWheel Court Retriever is protected by U.S. Utility Patent 11,844,984 B2 and supported by a functioning demo video showing the system performing its intended purpose. The prototype demonstrates real-world functionality, confirming that the concept works not only in theory, but as an integrated mechanical system.Patent: US 11,844,984 B2
Status: Issued U.S. utility patent
Stage: Working prototype / proof of concept
Availability: Not yet commercially available
The spring-assisted wheel concept behind SpringWheel Court Retriever has broader platform potential beyond tennis. The same design principle may be adapted to other rolling products, including luggage. Future powered versions may also extend the invention into more advanced retrieval systems capable of autonomously mapping an area and collecting balls with minimal user input.Three future-use cards:
Sports training systems
Luggage and rolling products
Powered autonomous retrieval
Pushpa Khemchand is an independent inventor focused on solving overlooked, real-world inefficiencies through practical design. SpringWheel Court Retriever reflects that approach by rethinking one of the most repetitive and physically demanding parts of tennis practice and replacing it with a more efficient system.
