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. 11,857,485.

Summary of the Inventive Concept

The present inventive concept relates to an advanced knee walker with four-wheel steering, featuring adaptive steering sensitivity, stability enhancement, customizable steering response, obstacle detection, and modular design for improved maneuverability, safety, and user experience.

Background and Problem Solved

The original knee walker with four-wheel steering patent (US1234567) provides improved maneuverability and stability in turning. However, it lacks adaptive features to accommodate varying user needs, terrain, and mobility requirements. The present inventive concept addresses these limitations by introducing advanced steering capabilities, enhancing the overall user experience and safety.

Detailed Description of the Inventive Concept

The enhanced four-wheel knee walker features a user-input device, processing unit, and actuation mechanism to adjust steering sensitivity based on user input. Additionally, a stability enhancement system dynamically adjusts the distribution of weight between the front and rear axles to improve turning stability. The knee walker also incorporates a sensor system to detect obstacles and automatically adjust the steering response to avoid collision. Furthermore, the modular design allows users to customize the steering response and adapt to different terrain or mobility requirements. The system can be configured to accommodate various user preferences, ensuring a more personalized and efficient mobility experience.

Novelty and Inventive Step

The new claims introduce novel and non-obvious features, including adaptive steering sensitivity, stability enhancement, customizable steering response, obstacle detection, and modular design. These advancements significantly improve the original knee walker's performance, safety, and user experience, distinguishing the present inventive concept from the prior art.

Alternative Embodiments and Variations

Alternative embodiments may include integrating the adaptive steering system with wearable devices, incorporating AI-powered obstacle detection, or developing specialized knee walkers for specific industries, such as healthcare or construction. Variations may also involve different materials, designs, or configurations for the modular steering components.

Potential Commercial Applications and Market

The enhanced four-wheel knee walker has vast commercial potential in the mobility aids market, targeting users with knee, lower leg, ankle, or foot injuries. The adaptive features and modular design make it an attractive solution for various industries, including healthcare, rehabilitation, and construction, where mobility and safety are paramount.
