Ball-and-Socket Pivoting Chair Mechanism for Core Muscle Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prolonged sedentary lifestyles and poor posture lead to back pain and musculoskeletal disorders due to inadequate mobility and core muscle weakness, which existing furniture and equipment fail to address effectively.
Innovation Solution
A three-dimensional pivoting system with a springy mechanism surrounding a ball and socket, secured by a pressure plate, allowing 360-degree motion in seating devices to promote therapeutic and physical conditioning by enhancing core muscle engagement and mobility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional fixed seating is used, then structural stability is maintained, but spinal health deteriorates due to lack of motion and core muscle weakness
Solution Approach 1:
The patent transforms the static chair into a dynamic system by incorporating a ball-and-socket joint mechanism with spring elements. This allows the seat to pivot 360 degrees and move in multiple directions, enabling users to perform therapeutic motions while seated. The dynamic structure actively engages core muscles and promotes spinal mobility, directly addressing the harmful effects of prolonged sitting.
Solution Approach 2:
The invention changes the mechanical parameters of the seating system by introducing variable motion capabilities through the spring-loaded ball-and-socket mechanism. The system allows for controlled pivoting and flexing motions that were previously absent in traditional chairs, transforming the seating experience from static to dynamically adjustable.
2Object-affected harmful factors
If a pivoting mechanism is added to enable 360-degree motion, then therapeutic conditioning is improved, but device complexity increases
Solution Approach 1:
The patent divides the chair into distinct functional segments: a fixed base, a movable seat assembly, and a connecting ball-and-socket mechanism. This segmentation allows the complex pivoting function to be isolated to a specific component rather than requiring the entire chair structure to be redesigned, thereby managing complexity while achieving therapeutic motion capabilities.
Solution Approach 2:
The ball-and-socket joint acts as an intermediary mechanism between the fixed base and the movable seat. This intermediate component enables the 360-degree pivoting motion while maintaining structural integrity, serving as a focal point for the mechanical complexity rather than distributing it throughout the entire chair structure.
3Productivity
If prolonged sitting is maintained for work and leisure, then productivity and comfort are preserved, but core muscle strength deteriorates
Solution Approach 1:
The chair automatically provides therapeutic conditioning benefits without requiring user intervention or additional equipment. As users naturally move and adjust their position during normal sitting activities, the mechanism engages core muscles and promotes spinal mobility, transforming a passive seating experience into an active conditioning session.
Solution Approach 2:
The pivoting mechanism enables continuous therapeutic motion throughout the entire sitting period. Unlike intermittent exercise routines, this system provides ongoing muscle engagement and spinal mobility promotion whenever the user is seated, making health benefits a continuous byproduct of normal work and leisure activities.

Function Achieved in This Case
The 360-degree pivoting mechanism improves spinal health by encouraging full-range motion exercises, strengthening core muscles, and reducing strain on the spine, thereby addressing back pain and musculoskeletal issues.
Implementation Method 1
a three-dimensional springy mechanism existing between the seat and the seat-supporting structure
Implementation Method 2
spring surrounding a ball and socket that enables the 360 degree motion

AI summary
A physical conditioning and therapeutic conditioning system that, when configured and incorporated into the construction of a chair, has a seat, a base configured to rest on a surface, and a seat-support mechanism which is configured to couple the seat to the base and enables the seat, when unlocked in one embodiment, to be pivoted in any direction while rocking in the seat and using one's own body weight for resistance. Ideally the seat-support mechanism permits universal motion in all directions above a vertical axis, including front to back inflection and side-to-side inflection of at least 40° , including 360° of rotation on a universal type joint. The universal type joint is a ball joint consisting of a bearing stud and socket enclosed in a case, with all parts made of steel. In one embodiment, the bearing stud is tapered and fits into a hydraulic post. A ball joint is used to allow free rotation in two planes at the same time.The universal ball joint when attached to the underside of a seat is surrounded by a metal caste collar, also attached to the underside of the seat, and with a locking system attached to the upper collar. Inserted into the upper collar, along with a lower collar attached to the arm support structure, surrounding the ball joint assembly is a hardened metal coiled spring, used ideally to stabilize, through compression, the seat in a horizontal position and allow for locking the seat in a horizontal position, when no force is applied or when not in use.
