This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,472.

Summary of the Inventive Concept

An improved wheelchair system that enhances stability, safety, and convenience for users, featuring a stabilizer mechanism, adjustable engager, and self-aligning technology.

Background and Problem Solved

The original wheelchair patent, while providing a means for users to securely engage with a vehicle body structure, has limitations in terms of stability and ease of use. The new inventive concept addresses these limitations by introducing a stabilizer mechanism, adjustable engager, and self-aligning technology to ensure a secure and convenient user experience.

Detailed Description of the Inventive Concept

The enhanced wheelchair system comprises a seat, body frame, wheel, seat back, and engager, as well as a stabilizer mechanism to maintain stability during engagement and disengagement. The engager can be adjusted for fine-tuning the engagement force between the seat back and vehicle body structure. Additionally, a sensor can be integrated to detect the distance between the engager and vehicle body structure, providing feedback to adjust the engager's position for optimal engagement. The self-aligning engager automatically adjusts its position to match the vehicle body structure's shape and size.

Novelty and Inventive Step

The new inventive concept introduces a stabilizer mechanism, adjustable engager, and self-aligning technology, which are not present in the original patent. These features provide a significant improvement in stability, safety, and convenience, making the new inventive concept novel and non-obvious.

Alternative Embodiments and Variations

Alternative embodiments of the enhanced wheelchair system could include different types of stabilizer mechanisms, adjustable engager designs, and self-aligning technologies. Additionally, the system could be adapted for use with various types of vehicles or mobility aids.

Potential Commercial Applications and Market

The enhanced wheelchair system has significant commercial potential in the mobility and healthcare industries, particularly in the areas of wheelchair accessibility and user convenience. The target market includes wheelchair users, caregivers, and mobility aid manufacturers.
