Intelligent Adjustable Seat Cushion Assembly
Legal Citation
Summary of the Inventive Concept
An improved seat cushion assembly that incorporates advanced materials, real-time adjustments, and user profiling to provide optimal support, pressure relief, and positional stability for wheelchair users.
Background and Problem Solved
The original adjustable seat cushion assembly patent had limitations in accommodating users of varying body types and sizes, as well as responding to changes in user position and weight distribution. This new inventive concept addresses these limitations by introducing an adjustable base, real-time air support adjustments, and a dynamic air support system, ensuring a more comfortable and supportive experience for users.
Detailed Description of the Inventive Concept
The Intelligent Adjustable Seat Cushion Assembly comprises an adjustable base defining a leg support, a support portion, and a well. The base is configured to be adjusted to accommodate users of varying body types and sizes. The assembly also includes an air pad assembly with multiple air support members that can be adjusted in real-time to respond to changes in the user's position and weight distribution. A sensor and processor system monitor the user's position and weight distribution, generating adjustment instructions for the air support members. The dynamic air support system adjusts air pressure in real-time to provide optimal support and pressure relief to the user.
Novelty and Inventive Step
The new claims introduce the concept of an adjustable base, real-time air support adjustments, and a dynamic air support system, which are not present in the original patent. These advancements provide a more personalized and responsive support system for users, making the inventive concept novel and non-obvious.
Alternative Embodiments and Variations
Alternative embodiments could include integrating sensors and processors into the seat cushion assembly, using machine learning algorithms to optimize user support, or incorporating additional features such as temperature control or massage functionality. Variations could include adapting the design for use in other types of seating, such as office chairs or car seats.
Potential Commercial Applications and Market
The Intelligent Adjustable Seat Cushion Assembly has significant commercial potential in the wheelchair and mobility aids market, as well as in other industries where customized seating solutions are valuable, such as healthcare, automotive, and office furniture.
