Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing chiropractic devices for spine correction and rehabilitation often require external forces and expert adjustments, making them cumbersome, time-consuming, and potentially harmful, especially for common spinal deformities like scoliosis in modern people due to poor posture.
Innovation Solution
A chiropractic device with an elongated flat base, semi-circular cylindrical support blocks, and adjustable stopping plates that utilize a user's own weight for spinal alignment and correction, providing a comfortable and adaptable solution without external force application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external pulling mechanisms are used to correct spine deformation, then spinal correction effect is improved, but device complexity and risk of secondary damage increase
Solution Approach 1:
The device enables users to perform spinal correction independently without requiring external operators or complex mechanical pulling mechanisms. The user's own body weight serves as the correction force, eliminating the need for complicated external force application systems and reducing the risk of operator-induced secondary damage.
Solution Approach 2:
The patent replaces complex mechanical pulling mechanisms with a gravity-based system. Instead of using motors, cables, or hydraulic systems to apply corrective force, the device utilizes the user's body weight under gravity to naturally stretch and align the spine, significantly simplifying the mechanical system.
2Reliability
If experienced personnel adjust spinal correction devices, then correction effectiveness is improved, but ease of operation deteriorates
Solution Approach 1:
The device is designed for self-application, allowing users to independently position and use the correction apparatus without requiring skilled operators. The intuitive design enables proper alignment through natural body positioning, making professional adjustment skills unnecessary for effective treatment.
Solution Approach 2:
The device creates an equipotential condition where the user's body weight naturally distributes along the spine through the specially designed surface geometry. This eliminates the need for skilled operators to manually adjust force distribution, as the device automatically achieves balanced correction across different user body types.
3Reliability
If repeated incremental tests are conducted to determine correct force, then spinal correction safety is improved, but loss of time increases
Solution Approach 1:
By replacing incremental force testing with a gravity-based system, the device eliminates time-consuming trial-and-error procedures. The user's body weight provides a consistent, naturally appropriate correction force from the start, removing the need for repeated adjustments and tests to determine safe force levels.
Solution Approach 2:
The device is pre-configured with surface geometry and structure that automatically adapts to individual user anatomy and weight. This preliminary design eliminates the need for on-site incremental testing, as the correction parameters are effectively predetermined by the user's own physical characteristics.
4Reliability
If protruding rubber sleeves and magnetic elements are arranged for spinal correction, then correction effect is improved, but ease of operation deteriorates
Solution Approach 1:
The patent integrates multiple correction functions into a single unified surface structure. Instead of separately arranging rubber sleeves and magnetic elements, the device combines support, alignment, and correction functions into one continuously contoured surface that automatically adapts to the spine's natural curvature and bony prominences.
Solution Approach 2:
The device features locally optimized surface geometry with varying curvature and elevation that automatically adapts to different regions of the spine. The surface is designed with specific local characteristics to accommodate bony spurs and anatomical variations without requiring manual arrangement of separate components.
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 effective and safe spinal rehabilitation and correction by leveraging the user's weight, allowing for easy adjustment and use by individuals without requiring expert assistance, effectively addressing the limitations of prior devices.
Implementation Method 1
The user's neck/head and hip are supported by the slant front and back support faces, and the two ends of the user's spine are pulled by the user's own weight

AI summary
The chiropractic device includes an elongated flat base, and a front stopping block and a back stropping block at the base's two ends. The front and back stopping blocks have a semi-circular cylindrical shape, with 45-degree slant support face on one end and a vertical face on the other end. Between the front and back stopping blocks, there are a main block and a number of stopping plates of different lengths. Along a top edge of the front and back stopping blocks, the main block, and the stopping plates, an end-to-end trough is provided. The chiropractic device is able to adapt its length so that users of different heights may lie on the chiropractic device for spinal relaxation and correction to the spine.
