Exercise Chair With Hinged Folding Frame And Independent Foot Bars
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional Pilates chairs lack independent, adjustable foot bars and the ability to fold into a compact shape for portability and storage.
Innovation Solution
An exercise chair with independent, adjustable foot bars that can be used separately or locked together, featuring a seat supported by hingeably connected support elements that can be folded for compact storage, along with a platform for stability and comfort, and variable resistance elements attached to the foot bars for customizable workouts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the chair structure is made rigid and fixed for stability during exercise, then stability is improved, but portability and storage capability deteriorate
Solution Approach 1:
The chair employs hinge connections between the seat and support elements, allowing the structure to dynamically transition between an unfolded stable configuration during exercise and a folded compact configuration for portability and storage. This dynamic adaptability resolves the contradiction between structural stability and portability.
2Device complexity
If a single foot bar is used to reduce device complexity, then ease of manufacture is improved, but adaptability for different users and exercises deteriorates
Solution Approach 1:
The foot bar system is segmented into two independent adjustable foot bars rather than a single fixed bar. Each foot bar can be independently positioned to accommodate different user requirements and exercise types, enhancing adaptability while maintaining reasonable device complexity through modular design.
3Adaptability or versatility
If the seat width is reduced to facilitate folding, then portability is improved, but user comfort and support deteriorate
Solution Approach 1:
The folding mechanism utilizes the lateral dimension by positioning hinges at the sides of the seat, allowing the support elements to fold horizontally alongside the seat rather than requiring reduction of seat width. This dimensional approach preserves user comfort while achieving compact folding for portability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The chair provides equal resistance to both legs, accommodates users with different strength levels, and can be easily folded for storage or transport, enhancing user flexibility and convenience.
Implementation Method 1
one or more resistance elements may be attached at a location beneath the seat, and connected with the lever of the foot bar
Implementation Method 2
the support elements are hingeably connected with the seat, so that when not in use, the support elements can be moved closer together and the chair can be folded into a compact shape
Implementation Method 3
the extensions may be coupled with a lever that is hingeably connected with one or more of the support elements

AI summary
An exercise chair primarily directed to employing an exercise method, with independent, adjustable foot bars and a foldable configuration. The seat is supported by a plurality of support elements, at least some of which are hingeably connected with the seat, so that the chair can be folded into a compact shape for storage or transport. The independent foot bars may each be attached to a lever that is hingeably coupled with one or more of the support elements. The position of the foot bars may also be adjustable by extending out of the levers and locking into the desired position. One or more resistance elements may be removably attached to a location below the chair seat, and individually connected with the levers via an adjusting assembly that can either slide or be placed in pre-set mounting locations along the lever to provide variable resistance, or can be equipped with a turnbuckle to provide varying resistance. A platform that rests at or near the floor during use may be attached to the two front support elements, which provides stability as well as comfort when the user stands or kneels on the platform when using the chair.
