Posture Control Chair with Dynamic Retainer for Slouching Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing office chairs do not provide effective active posture correction for white-collar workers, leading to prolonged sitting-related health issues such as fatigue, obesity, diabetes, hypertension, cancer, and heart disease, as well as aggravating hip, back, or neck ailments.
Innovation Solution
A chair with a back rest assembly that includes a head or neck rest, lumbar support, arm rest, and posture retainer, all adjustable to distribute weight and dynamically adjust to the user's body, combined with a knee rest assembly and optional heating, cooling, or massaging features to prevent slouching and promote adaptive comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a traditional office chair is used, then the chair structure is simple and cost-effective, but it does not provide active posture correction and leads to health issues from prolonged sitting
Solution Approach 1:
The chair is divided into multiple functional segments: a seat assembly with weight distribution mechanisms, a backrest assembly with posture correction elements, and a control system. This segmentation allows each component to address specific posture-related issues independently, providing comprehensive health protection without requiring complete system redesign.
Solution Approach 2:
The chair integrates multiple functions into a single device: weight distribution, active posture correction, lumbar support, and adjustable positioning. This multi-functionality addresses various sitting-related health issues simultaneously, reducing the need for multiple separate devices while managing complexity through integrated design.
2Ease of operation
If existing posture assistance mechanisms are added to chairs, then posture support is improved, but the device complexity and adjustment requirements increase
Solution Approach 1:
The posture correction system operates autonomously by detecting user posture through sensors and automatically adjusting support elements accordingly. This self-service mechanism eliminates the need for manual adjustments by the user, maintaining high posture support quality while reducing operational complexity.
Solution Approach 2:
The chair incorporates sensors that continuously monitor user posture and provide feedback to the control system, which then makes real-time adjustments to posture correction mechanisms. This closed-loop feedback system ensures optimal posture support without requiring user intervention or complex manual adjustment procedures.

AI summary
A posture correcting chair having a back rest assembly providing mounting attachments for a head or neck rest, a lumbar support, at least one arm rest, and a posture retainer and supported by a seat assembly. The headrest, lumbar, seat and back support all adjust to allow a user to distribute their weight about a greater number of surfaces for adaptive comfort. A posture retainer affixed to the back rest assembly dynamically adjusts to the contour of a user's body based on force and pressure created while seated to provide active posture correction for a user to prevent slumping or slouching. A knee rest assembly is attached to rail system on a lower end of chair the base platform to provide additional support surfaces. The seat and knee rest assembly include heating, cooling or vibrating or massaging.
