Solution Overview

Problem

Current treatments for spinal deformities, such as scoliosis, are largely ineffective in correcting the deformity and only prevent further progression, while existing methods like braces and skeletal traction are uncomfortable and require frequent sessions.

Innovation Solution

A system comprising tensioners, cables, and a frame that applies lateral forces to the spine through a ratcheting mechanism, allowing precise tension adjustment and continuous wear to correct spinal deformities, with optional vibration components for comfort and muscle relaxation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If skeletal traction is used to correct spinal deformities, then lateral forces can be applied to the spine, but the treatment requires frequent sessions lasting 20-30 minutes each and is uncomfortable for the subject

Engineering Contradiction:
Improvecorrective effectivenessVSAvoidtreatment session frequency and duration
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The device transitions from static bracing to dynamic active correction through a ratcheting mechanism that allows incremental adjustment of lateral forces. The tensioning mechanism enables the subject to actively engage muscles and progressively adjust the corrective force, making the treatment adaptable and effective over time rather than requiring frequent reapplication.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The subject actively participates in the correction process by engaging their own muscles to counteract the lateral forces applied by the device. The ratcheting mechanism allows the subject to self-adjust the tension incrementally, making the treatment self-regulating and eliminating the need for frequent professional intervention sessions.

Inventive Principle:
Principle #25Self-service

2Stability of the object's composition

If braces are used to prevent progression of spinal deformities, then further deterioration can be prevented, but the braces are essentially ineffective as a corrective measure

Engineering Contradiction:
Improvespinal alignment stabilityVSAvoidcorrective effectiveness
Core Design Contradiction:
Stability of the object's compositionVSReliability

Solution Approach 1:

The device transforms passive bracing into active correction through a dynamic ratcheting mechanism. Instead of merely holding the spine in place, the mechanism allows progressive adjustment of lateral forces, enabling the spine to be actively corrected while maintaining stability during the correction process.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The device applies preliminary lateral forces to gradually correct spinal deformities before the subject's daily activities can cause progression. By pre-positioning the spine in a corrected alignment and maintaining it through adjustable tension, the device prevents both progression and addresses existing deformities.

Inventive Principle:
Principle #10Preliminary action

AI summary

Treatment of a spinal lateral translation may be carried out by tensioning a cable that is set around a subject at the approximate height of the lateral translation. A tensioner may tension the cable, thereby directing a lateral corrective force from one or more anchor points toward the spinal deformity. Tension may be applied to the cable by a tensioning assembly such as one having a ratcheting device. A frame can maintain the anchor point(s), cable(s), and tensioning assembly(ies) at desired vertical and/or lateral positions. A device comprising the foregoing components may be wearable by the subject.
