Solution Overview

Problem

Existing back orthoses are limited in their adaptability to individual patient anatomies, often compromising stabilizing effectiveness for broader anatomical coverage.

Innovation Solution

A back orthosis with a first and second flat stabilizing element connected by an elongated stabilizing rail, allowing translational displacement for personalized fit, and featuring adjustable side parts and pretensioning mechanisms for enhanced stability and comfort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the back orthosis is designed with fixed stabilizing elements, then the stabilizing effect is maximized, but the adaptability to different patient anatomies is limited

Engineering Contradiction:

Improvestabilizing effectVSAvoidadaptability to patient anatomy

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The back orthosis incorporates stabilizing elements with guided translational displacement capability along the longitudinal direction, allowing the elements to dynamically adjust their positions to accommodate different patient anatomies while maintaining stable coupling through the stabilizing rail

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The orthosis is divided into multiple stabilizing elements (first and second flat stabilizing elements) that can independently adjust their positions along the stabilizing rail, enabling segmented adaptation to various anatomical conditions while each element maintains its stabilizing function

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If the back orthosis is designed with adjustable components for better anatomical fit, then the adaptability is improved, but the device complexity increases

Engineering Contradiction:

Improveanatomical fitVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The guided translational displacement mechanism provides adjustability through a simple linear movement constraint along the stabilizing rail, achieving anatomical adaptation without complex multi-degree-of-freedom joints or adjustment mechanisms

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The stabilizing rail serves multiple functions: it couples the stabilizing elements together, guides their translational displacement for adjustment, and maintains stable coupling throughout the adjustment range, reducing the need for separate adjustment mechanisms

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

The present invention relates to a back orthosis (10; 180) for stabilizing a patient's back, comprising: - a first planar stabilizing element (12) for supporting the patient's back; - a second planar stabilizing element (14) for supporting the patient's back below the first planar stabilizing element (12); and - an elongated stabilizing rail (16) that couples the first and second planar stabilizing elements (12; 14) together and is guided relative to the first and/or second planar stabilizing element in such a way that a guided translational displacement of the first and second planar stabilizing elements (12; 14) relative to each other in the longitudinal direction (L) of the stabilizing rail (16) is possible for adapting the back orthosis (10; 180) to the patient.
