Seated Inversion Table with Front Swinging Rod to Prevent Over-Tilting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional seated inversion tables lack protective structures to prevent over-inversion, which increases the risk of injury, and they are not easily adjustable or foldable for storage in limited spaces.
Innovation Solution
The seated inversion table incorporates a support frame assembly with a front swinging rod that restricts inversion angle, a seat back assembly with a rear-rod-tilting frame, and an adjustable foot-clamping frame assembly, along with a rotating frame and band system to prevent over-tilting and facilitate storage by allowing components to be removed and folded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the conventional seated inversion table is provided with a seat cushion assembly tiltably mounted between front and rear support components, then the user can perform inversion exercise to stretch abdominal and back muscles, but the table lacks protective structure to prevent over-inversion, increasing injury risk
Solution Approach 1:
The patent applies preliminary anti-action by providing a limiting structure that prevents over-inversion before injury can occur. The limiting rod is positioned to make contact with the user's body or the inversion table structure at a predetermined point, creating a mechanical stop that counteracts the continuing inversion motion and protects the user from exceeding the safe inversion angle.
2Ease of manufacture
If the distance between fixing rods of the foot-clamping frame assembly is fixed, then the structure is simple, but the user's foot cannot hook on the fixing rods firmly when sitting on the cushion
Solution Approach 1:
The patent applies dynamics by making the distance between the fixing rods adjustable rather than fixed. The foot-clamping frame assembly includes a adjusting mechanism that allows the user to modify the spacing between fixing rods according to their foot size and preference, enabling firm hooking of the feet while maintaining ease of manufacture through a straightforward adjustment mechanism.
3Adaptability or versatility
If the seated inversion table is designed for particular inversion purpose, then it provides specialized functionality, but it is not suitable for other purposes and difficult to store in limited housing space
Solution Approach 1:
The patent applies segmentation by dividing the inversion table into separable components. The seat cushion assembly, foot-clamping frame assembly, and other components can be detached from the main support structure, allowing the table to be disassembled into smaller parts for compact storage in limited housing space while maintaining its specialized inversion exercise functionality when assembled.
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 solution effectively restricts the inversion angle to prevent user injury and allows for easy storage by ensuring the front swinging rod abuts the upper bars during use and enabling the table to be folded for space efficiency.
Implementation Method 1
the front swinging rod will be located at an end of the stroke and abut on the upper bars when the user performs inversion on the seated inversion table. Thus, a range of an inversion angle is restricted
Implementation Method 2
a band, one end of the band securely mounted on the connecting tube of the support frame assembly and detoured around the guiding stand
Implementation Method 3
a rear swinging rod, two opposite ends of the rear swinging rod tiltably mounted on the support frame assembly
Implementation Method 4
a front swinging rod, two opposite ends of the front swinging rod tiltably mounted on the support frame assembly
Implementation Method 5
a cushion bottom rod, one end of the cushion bottom rod securely mounted on the rear swinging rod of the seat back assembly, and another end of the cushion bottom rod securely mounted on the front swinging rod

AI summary
The seated inversion table is provided having a support frame assembly, and a seat back assembly, and a seat cushion assembly tiltably mounted on the support frame assembly. The seat back assembly connects to the seat cushion assembly and connects to a rotating frame assembly through a lower connecting tube assembly. The rotating frame assembly is tiltably mounted on the seat cushion assembly and is adjustably mounted on a foot-clamping frame. With a front swinging rod of the seat cushion assembly tiltably mounted on the support frame assembly, a range of an inversion angle is restricted and thereby the seated inversion table may not over tilt.
