Summary of the Inventive Concept
The present invention combines a wheelchair suspension system with advanced technologies such as AI, IoT, blockchain, and new materials to create a more powerful and efficient system for navigating obstacles.
Background and Problem Solved
Wheelchairs and scooters are essential for people with mobility impairments, but they often struggle with traversing obstacles like curbs, driveways, and sidewalks. The original patent addressed this issue with a suspension system, but it had limitations in terms of real-time monitoring, predictive maintenance, and data storage. The present invention solves these problems by integrating advanced technologies to create a more intelligent and efficient wheelchair suspension system.
Detailed Description of the Inventive Concept
The new inventive concept combines a wheelchair suspension system with an AI-powered obstacle detection module, IoT-enabled sensors for real-time monitoring, and a blockchain-based data storage system for recording navigation data. This integration enables the system to predict and adapt to various obstacles, providing a smoother and safer ride for users. The system can also optimize suspension settings for traversing different obstacles, perform predictive maintenance, and harvest energy using new materials.
Novelty and Inventive Step
The new claims introduce a synergistic combination of distinct technologies, which is not obvious from the original patent. The integration of AI, IoT, blockchain, and new materials with a wheelchair suspension system creates a novel and non-obvious solution that addresses the limitations of the original patent.
Alternative Embodiments and Variations
Alternative embodiments may include different AI-powered modules, such as machine learning algorithms for predictive obstacle avoidance or natural language processing for user interface. Variations may also include different types of IoT-enabled sensors, blockchain-based data storage systems, or new materials for energy harvesting.
Potential Commercial Applications and Market
The intelligent wheelchair suspension system has significant commercial potential in the healthcare and mobility industries, particularly for users with mobility impairments. The system can be integrated into various types of wheelchairs and scooters, providing a competitive advantage in the market.
