Chair with upper frontal support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional chairs lack adjustability to accommodate users of different shapes and sizes, providing sub-optimal ergonomics and limited versatility for various applications, as their adjustable features are fixed within a limited range.
Innovation Solution
A seating system with a rotatably adjustable upper body support that has multiple profiles, allowing rotation between positions corresponding to different profiles, and is optionally replaceable, enabling customization for user comfort and versatility across various tasks and user sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional chairs use fixed adjustable features, then the structure is simple and easy to manufacture, but the adaptability to different user shapes and sizes is limited
Solution Approach 1:
The upper body support is made rotatable about an axis extending from the mount, allowing it to dynamically change orientation between multiple positions. Each position corresponds to a different profile that accommodates various user shapes and sizes, transforming a static structure into a dynamic one that adapts to different ergonomic requirements
Solution Approach 2:
The upper body support is designed with multiple distinct profiles along its rotational path, effectively segmenting the support function into different configurations. Each profile serves a specific ergonomic purpose, allowing the single component to provide multiple specialized support options rather than requiring separate components for each user type
2Reliability
If traditional chairs have limited adjustment range, then the device complexity is reduced, but the ergonomics optimization is sub-optimal
Solution Approach 1:
The rotatable upper body support provides a continuous range of motion around an axis, enabling smooth transitions between multiple adjustment positions. This dynamic adjustment mechanism allows precise positioning to optimize ergonomics for different tasks and user anatomies, far exceeding the limited discrete adjustments of traditional chairs
Solution Approach 2:
The single rotatable upper body support structure serves multiple ergonomic functions through its different positional profiles. One profile may optimize for typing tasks, another for reading, and another for different body types, making the chair universally applicable to various users and tasks without requiring multiple specialized components

AI summary
A seating system includes a base extending from a lower end to an upper end, a lower body support coupled to the base proximate the upper end of the base, a mount extending from a lower end to an upper end, and an upper body support rotatably mounted to the mount proximate the upper end of the mount. The upper body support is shaped to receive an upper body of the user and has at least three profiles. The upper body support is rotatable between a plurality of positions, each position in the plurality of positions corresponding to one of the at least three profiles of the upper body support.
