Adjustable Seating Assembly With Rotating Chest and Seat Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional adjustable therapeutic chairs are not designed for daily or prolonged use, often obstructing the user's view and vocalization, and lack optimal ergonomic support for the spine, making them unsuitable for home or office settings.
Innovation Solution
An adjustable seating assembly with a chest-support surface oriented at an acute angle relative to the seating-support surface, allowing for simultaneous rotation and adjustment of both surfaces, along with a chin-support and arm-rests positioned to facilitate comfortable working without obstructing vision or vocalization, ensuring optimal spine support and ergonomic positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If adjustable therapeutic chairs include arm, leg, and/or facial rest surfaces, then user comfort is improved, but the user's view and vocalization are obstructed
Solution Approach 1:
The chin rest is extracted or removed from the chair design. The patent explicitly states that conventional therapeutic chairs include facial rest surfaces that obstruct the user's view and vocalization, and the invention resolves this by eliminating this component while maintaining other comfort features.
Solution Approach 2:
The chair is divided into separate functional components: arm rests and leg rests are retained for comfort, but the chin rest is separated/removed. This segmentation allows the chair to provide comfort without the harmful obstruction of view and vocalization.
2Adaptability or versatility
If therapeutic chairs are designed with multiple adjustment features, then adaptability is improved, but device complexity increases
Solution Approach 1:
The chair provides multiple adjustment features (arm rest adjustment, leg rest adjustment, seat position adjustment) that serve universal ergonomic purposes. These adjustments are designed to accommodate different user needs and positions without requiring overly complex mechanisms.
3Reliability
If therapeutic chairs are configured for primary user therapy, then therapeutic effectiveness is improved, but ease of operation for daily use deteriorates
Solution Approach 1:
The chair is designed to be easily adjusted by the user themselves without requiring a secondary operator. The adjustment mechanisms are positioned and designed for intuitive user operation, allowing individuals to independently configure the chair for their therapeutic needs and daily comfort.

AI summary
An adjustable seating assembly is disclosed having a base with a first end, a second end opposite the first end, and a length extending from the first end to the second end. A frame assembly has a pair of support legs coupled to the base along the length. A seating-support surface is disposed above the base and coupled to the frame assembly. A chest-support surface is disposed above the base and coupled to the frame assembly and the chest-support surface is orientated at an acute angle with respect to the seating-support surface. The pair of the support legs are selectively translatable along the length of the base in a first direction and a second direction opposite the first direction so as to selectively rotate the chest-support surface and the seating-support surface simultaneously while maintaining the acute angle between the chest-support surface and the seating-support surface during the rotation.
