Spinal Orthotic Backrest Structure for Stable Vertebral Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional backrests fail to provide proper and stable support for thoracic and lumbar vertebrae, lead to incorrect sitting postures, occupy excessive space, and lack features like acupressure and electrotherapy, ultimately causing muscle fatigue and improper vertebral alignment.
Innovation Solution
A portable spinal orthotic backrest with a plastic back support plate featuring upper and lower portions conforming to thoracic and lumbar curvatures, protruding knobs for acupressure, suspension braces for resilience, a cervical vertebrae support plate with height adjustment, and embedded conductive elements for electrotherapy, ensuring proper vertebral alignment and muscle relaxation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional backrests use foam cushions to simulate support, then users feel comfortable initially, but the support becomes unstable and causes improper vertebral positioning after long-term use
Solution Approach 1:
The backrest is divided into multiple functional segments: a rigid support board providing structural stability, and separate foam cushions positioned only at contact points for comfort. This segmentation allows the rigid board to maintain proper vertebral positioning while the foam cushions provide localized comfort without compromising support stability.
Solution Approach 2:
Instead of uniformly soft foam cushions throughout, the invention applies foam cushions only at specific local areas where user contact occurs. The rigid support board provides stable support in areas requiring structural integrity, while foam cushions provide comfort only where needed, resolving the contradiction between stability and comfort.
2Ease of operation
If conventional backrests use bulky foam cushions, then comfort is provided, but excessive sitting space is occupied
Solution Approach 1:
The backrest separates the support function (rigid board) from the comfort function (foam cushions), allowing the rigid board to be thin and space-efficient while foam cushions are minimized to only necessary contact areas, thus reducing overall space occupation.
Solution Approach 2:
The invention uses a thin rigid support board instead of bulky foam structures, creating a compact backrest that occupies minimal sitting space while still providing effective support through its rigid structure.
3Ease of operation
If conventional backrests use hard boards without foam, then structural stability is maintained, but user comfort and muscle relaxation are insufficient
Solution Approach 1:
The invention applies foam cushions only at specific local contact areas where user comfort is needed, while the rigid support board maintains structural stability in areas requiring support. This localized application of foam resolves the contradiction by providing comfort only where it aids muscle relaxation without compromising overall support stability.
4Ease of operation
If conventional backrests lack acupressure features, then structural simplicity is maintained, but muscle relaxation and vertebral fine-tuning are insufficient
Solution Approach 1:
The invention merges the support function of the rigid board with the muscle relaxation function of foam cushions that have acupressure knobs integrated into them. This combination allows the backrest to provide both structural support and therapeutic muscle relaxation without requiring separate devices, thus managing complexity while enhancing functionality.

AI summary
The present invention is to provide a back support plate, which is integrally formed of plastic and includes an upper portion with an inner-side having a vertical curvature and a horizontal curvature that respectively conform to the curvature of human thoracic vertebrae and a horizontal curvature of the human back corresponding in position to the thoracic vertebrae, and a lower portion with an inner-side having a vertical curvature and a horizontal curvature that respectively conform to the curvature of human lumbar vertebrae and a horizontal curvature of the human back corresponding in position to the lumbar vertebrae. The two inner-sides are protrudingly provided with a plurality of protruding knobs which correspond in position to two lateral sides of the thoracic and lumbar vertebrae and have upwardly and downwardly decreasing widths, respectively, such that the joining section between the two portions extends to the two lateral sides of the human back.
