Adjustable Stretch Bar for Inversion Therapy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current inversion therapy tables lack mechanisms for users to adjust the level of stretching or inversion therapy independently of the inversion angle, limiting user comfort and effectiveness, as some users cannot or do not want to achieve desired stretching by increasing the inversion degree, and there is no way to apply less stretching without decreasing the angle.
Innovation Solution
An adjustable stretch bar system with handles that users can pull or push to increase or decrease the stretching force, allowing for adjustable inversion therapy without altering the table's inversion angle, featuring adjustable bars for user size accommodation and a restraining bar to limit inversion angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the inversion angle of the table is increased to provide greater stretching, then the degree of inversion therapy is improved, but user comfort and adaptability deteriorate for users who cannot tolerate steep inversion slopes
Solution Approach 1:
The invention separates the control of stretching force from the inversion angle by introducing an independent stretch bar mechanism. Users can adjust the stretching force through hand pressure on the stretch bar without changing the inversion angle, thus resolving the contradiction between achieving greater stretching and maintaining user comfort/adaptability.
2Ease of operation
If the inversion angle is decreased to reduce stretching, then user comfort is improved, but the effectiveness of inversion therapy deteriorates
Solution Approach 1:
The stretch bar mechanism allows independent adjustment of stretching force separate from inversion angle. Users can maintain a comfortable inversion angle while still achieving effective stretching through manual pressure on the stretch bar, thus maintaining both comfort and therapy effectiveness.
3Force
If the inversion angle is increased to achieve desired stretching, then stretching effectiveness is improved, but the risk of excessive inversion and injury increases
Solution Approach 1:
The stretch bar acts as an intermediary mechanism that allows users to apply stretching force independently of the inversion angle. This mediates between the user's need for stretching and the safety constraint against excessive inversion, enabling effective therapy without increasing inversion angle beyond safe limits.
4Device complexity
If a fixed inversion angle is used, then device simplicity is maintained, but user customization and versatility deteriorate
Solution Approach 1:
The stretch bar is designed as a dynamic, adjustable component that allows users to modify the stretching force according to their needs. This adds adaptability and customization capability to the device while maintaining relatively simple device structure through a straightforward mechanical adjustment mechanism.
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
Enables users to customize the level of inversion therapy for comfort and effectiveness, accommodating varying user sizes and preferences, while preventing excessive inversion and allowing for reduced stretching without changing the table's angle.
Implementation Method 1
the stretch bar includes handles that the user may grasp with their hands. While on the inversion table, the user may pull on the handles to apply more stretching, or push against the handles to decrease the amount of inversion therapy
Implementation Method 2
While inverted, gravity on the user provides stretching to the user's body and thereby inversion therapy

AI summary
A stretch bar for an inversion therapy table. The stretch bar has two support bars that are connected at one end by a connecting beam and has handles at the other ends of the support bars. The handles are located above the user and enable the user to pull or push on the handles to increase or decrease the amount of inversion therapy. The support bars may be adjustable in length, such as by using a pin and hole adjustment configuration. The support bars may be connected by a second connecting beam.
