APPARATUS AND METHOD FOR AUTOMATED WHEELCHAIR ASSISTANCE

Smart overview of the Invention

The invention focuses on an apparatus and method for converting a manual wheelchair into an automated one, offering enhanced mobility and ease of use. This lightweight apparatus can be easily attached to and detached from a manual wheelchair. It includes touch contact sensing technology to detect the user's hand on the handrims, allowing the system to provide assistive force to the rear wheels, thus aiding propulsion. The apparatus further integrates with network devices, enabling remote control functionalities, such as moving the wheelchair towards or away from the user without direct physical input.

Background

Manual wheelchairs require significant physical effort and upper body strength, limiting mobility for some users. Power wheelchairs, while offering motorized assistance, are often heavy, expensive, and challenging to transport. Electric wheelchairs are lighter but lack durability for diverse terrains. There is a need for a simple solution that automates manual wheelchairs without adding cumbersome controls like joysticks or touchpads, providing ease of use through intuitive handrim interaction.

Challenges Addressed

The invention addresses several challenges in automating manual wheelchairs. It eliminates the need for traditional controls by allowing activation and deactivation through handrim touches. The system maintains direction and speed even when hands are off the rims, reducing physical strain and potential injuries. Additionally, it incorporates remote control features using mobile devices, enabling users to move the wheelchair remotely and manage power settings effectively.

Technological Integration

The apparatus leverages modern technology, including AI and sensors, to enhance wheelchair operation. These technologies assist in regulating speed and navigation while collecting data for precise control and emergency location tracking. A smart speaker interface offers voice command capabilities, providing users with an additional layer of assistance during health emergencies or operational challenges.

Comparative Solutions

Previous attempts to automate manual wheelchairs have included various systems involving joysticks, motors, and friction rollers. However, these solutions often add weight and complexity or require significant modifications to the wheelchair structure. The current invention distinguishes itself by being lightweight, easily attachable, and operable without extensive physical controls. This approach simplifies conversion while enhancing user experience through seamless integration with existing mobile technologies.
