Decompression chair for lower back
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for relieving spinal compression, such as stretching exercises and decompression tables, are not suitable for self-administration during daily activities, as they do not provide adequate support and decompression while allowing for mobility and use of the hands.
Innovation Solution
A back decompression system comprising an adjustable height seat, vertical arms, and a harness that hangs from these arms, allowing for 360-degree rotation of the seat and limited rotation of the harness, enabling users to move and perform tasks while maintaining spinal decompression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex decompression apparatuses with multiple connection points are used, then spinal decompression effectiveness is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The decompression system is segmented into independent functional components: a simple seat for positioning, a separate vertical stand for support, and a harness with adjustment mechanisms for decompression. This segmentation allows each component to be optimized independently while maintaining overall effectiveness, reducing the complexity of any single component.
Solution Approach 2:
The harness incorporates dynamic adjustment mechanisms including adjustable strap lengths and movable connection points that allow the system to adapt to different user sizes and decompression requirements. This dynamic adaptability maintains decompression effectiveness across various users without requiring complex fixed-configuration apparatuses.
2Reliability
If complex decompression apparatuses with multiple connection points are used, then spinal decompression effectiveness is improved, but ease of operation worsens
Solution Approach 1:
The system enables self-administration through intuitive self-adjustment mechanisms. Users can independently modify strap lengths, positioning, and tension without requiring professional assistance or complex control systems. The self-service capability maintains decompression effectiveness while dramatically improving ease of operation.
Solution Approach 2:
The harness allows users to change key parameters such as strap length, connection point position, and tension level through simple mechanical adjustments. These parameter changes enable effective decompression adaptation without requiring complex electronic controls or professional intervention.
3Reliability
If fixed decompression apparatuses are used, then spinal decompression support is improved, but adaptability to daily activities worsens
Solution Approach 1:
The decompression system is designed with universal applicability to multiple daily activities. The adjustable harness and positioning mechanisms allow the same device to support decompression during typing, writing, eating, and other routine activities. This multi-functionality maintains decompression support while enabling adaptability to various daily contexts.
Solution Approach 2:
The system incorporates dynamic adjustment capabilities that allow real-time modification of decompression parameters during different activities. Users can adjust strap tension, positioning, and configuration to suit specific activity requirements while maintaining continuous spinal support, enabling both reliability and adaptability.
4Reliability
If continuous decompression is maintained during daily activities, then back pain relief is improved, but device complexity worsens
Solution Approach 1:
The system provides continuous decompression through self-sustaining mechanical tensioning mechanisms that require no active control or power source. Once adjusted, the harness maintains decompression force passively through its structural design, enabling continuous pain relief without adding electronic complexity or control systems.

AI summary
A spinal decompression harness which hangs from two lines on either side, is attached to a stand. A stool or seat is between the two sides of the stand, and the stand can be attached to a neck of the stool. In this manner, the harness is movable between the two sides of the stand, and one can rotate one or more of the harness, seat, or stand while keeping one's torso abutted to the harness. Their arms can also extend over the harness and be used for writing, typing, and other work, while their spine is decompressed in the harness.
