Back Orthosis Two-Part Shoulder Strap Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing back orthoses lack sufficient adaptability to individual anatomical and pathological conditions, requiring significant effort and trained personnel for adjustment, limiting their effectiveness and comfort during therapy.
Innovation Solution
A back orthosis with a two-part shoulder strap design, adjustable length, and a deflection element system that allows for independent adjustment of upper and lower strap sections, facilitating easier application and customization to patient-specific needs, enhancing wearing comfort and therapeutic efficacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If back orthoses are designed with fixed structure and single-piece shoulder straps, then manufacturing is simpler, but adaptability to individual patient anatomy is insufficient
Solution Approach 1:
The shoulder strap is divided into two separate parts: an upper shoulder strap section and a lower shoulder strap section. This segmentation allows each section to be independently adjusted and positioned, enabling the orthosis to adapt to various patient anatomies without requiring an entirely custom-designed device.
Solution Approach 2:
The orthosis incorporates adjustable elements including the two-part shoulder strap system with independent positioning, and a deflection element that can be relocated along the back element. These dynamic features allow the device to be customized for different patient needs while maintaining a standardized base structure.
2Adaptability or versatility
If back orthoses are made individually customized for each patient, then adaptability is maximized, but application effort and requirement for trained personnel increases significantly
Solution Approach 1:
The orthosis is pre-configured with adjustment mechanisms including the two-part shoulder strap system and relocatable deflection element positioned on the back element. These preliminary arrangements enable patients or caregivers to perform simple adjustments without requiring specialized training or complex procedures.
Solution Approach 2:
By dividing the shoulder strap into adjustable upper and lower sections, the system allows for easy customization during application. Each section can be independently positioned and secured, simplifying the fitting process while achieving patient-specific adaptation.
3Ease of operation
If traditional single-piece shoulder straps are used, then device structure is simpler, but ease of adjustment and patient comfort are reduced
Solution Approach 1:
The shoulder strap is divided into an upper shoulder strap section extending from the back element over the shoulder, and a lower shoulder strap section extending from the upper section to the hip belt arrangement. This segmentation enables independent adjustment of each section to optimize comfort and fit for different patients.
Solution Approach 2:
The adjustable two-part shoulder strap system allows dynamic reconfiguration to accommodate various patient anatomies and comfort preferences, transforming a static component into an adaptable element that enhances ease of operation.
4Adaptability or versatility
If the deflection element position is fixed on the back element, then manufacturing is easier, but adaptability to different patient requirements is limited
Solution Approach 1:
The deflection element is designed to be relocatable along the back element rather than fixed at a single position. This dynamic feature allows the strap course to be adjusted for different patient anatomies and therapeutic requirements while maintaining a standardized manufacturing process for the back element itself.

AI summary
The present invention relates to a back orthosis (10) comprising a back element (12) with a stabilizing body (14) that supports the back, a hip belt assembly (20) connected to the back element, and a shoulder belt assembly (40) with at least two shoulder belt pulleys (42, 44), wherein each shoulder belt pulley, when attached to the patient, is guided from the back element over a shoulder of the patient through at least one deflection element (32) arranged on the back element to the hip belt assembly and can be coupled or coupled to the hip belt assembly.Furthermore, the invention provides that the two shoulder straps are two-part, wherein the two shoulder straps further comprise at least one upper shoulder strap section (46) extending from the back element to over the shoulders, and at least one lower shoulder strap section (48) extending from the upper shoulder strap section over the deflection element arranged on the back element to the hip belt arrangement, and wherein the at least one upper shoulder strap section of one of the two shoulder straps and the at least one lower shoulder strap section of this shoulder strap can be connected to each other via a connecting element (60), so that the length of at least one of the shoulder straps is adjustable.
