Adjustable Desk Posture Support for Forward-Leaning Work
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ergonomic chairs fail to effectively support users' posture while working at a desk, as they are designed for sitting upright and do not provide adequate support when users lean forward, leading to strain on the piriformis muscle and sciatic nerve, and are often inconvenient for users with mobility issues or those who need to straddle the chair.
Innovation Solution
A portable posture support system that includes a base, adjustable vertical and horizontal arm portions, and a cushion support, which can be placed on a desk to provide resistance and spinal support, allowing users to maintain proper posture by aligning their ears over their shoulders and keeping their upper chest against the support portion, thus preventing slouching and leaning forward.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional ergonomic chairs with back support are used, then spinal support is provided when sitting upright, but the user cannot effectively utilize the back support when leaning forward to work at a desk
Solution Approach 1:
Instead of providing back support from behind the user, this invention places the support cushion in front of the user's torso. The cushion supports the user's chest and upper body from the front, allowing effective posture maintenance when leaning forward to work at a desk, which is the opposite approach of traditional chair backrests.
2Reliability
If users straddle the chair to utilize front support, then posture support is provided, but the solution becomes inconvenient for users with mobility issues
Solution Approach 1:
This invention extracts the posture support function from the chair itself and creates a separate, portable cushion system that can be placed on the desk. This removes the requirement for users to straddle or reposition themselves on the chair, making it accessible to users with mobility issues while maintaining effective front support.
3Reliability
If adjustable arms and cushion support are added to provide resistance and spinal support, then posture maintenance is improved, but the device complexity increases
Solution Approach 1:
The posture support system is divided into separate adjustable components: vertical arm portions, horizontal arm portions, and a cushion support. Each component can be independently adjusted and positioned, allowing the system to adapt to different users and workspaces while maintaining manageable complexity through modular design.

AI summary
A posture support system that includes a base portion, a vertical arm portion extending from the base portion, a horizontal arm portion extending from the vertical arm portion, and a support portion extending from the horizontal arm portion. The base portion includes a rectangular board that rests on a flat surface. The vertical arm and horizontal arm portions are fully adjustable to accommodate different users when a user rests against the support portion to perform work, such as typing, on the flat surface. The posture support system induces proper seated posture.
