Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seating structures lack comprehensive support for the upper thoracic and lumbar regions, leading to discomfort and potential health issues during prolonged use.
Innovation Solution
The seating structure incorporates a base, a seat, a backrest with a frame and suspension material, and adjustable support assemblies for the upper thoracic and lumbar regions, along with a pivotable headrest assembly for enhanced user comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If adjustable support assemblies are added for upper thoracic and lumbar regions, then user comfort and support quality improve, but device complexity increases
Solution Approach 1:
The backrest is divided into multiple functional zones with separate support assemblies: upper thoracic support assembly with pad and adjustment mechanism, lumbar support assembly with pad and adjustment mechanism, and lower thoracic support assembly. Each assembly independently supports specific regions, allowing tailored adjustment for optimal comfort without requiring complete redesign of the entire backrest structure.
Solution Approach 2:
The support assemblies incorporate adjustable mechanisms including cam members that can be rotated to engage support brackets at different positions, and pivotable headrest assemblies. These dynamic elements allow users to customize the support configuration according to their individual needs, enhancing comfort while maintaining a relatively simple base structure.
2Adaptability or versatility
If multiple adjustment mechanisms are incorporated, then adaptability to different users improves, but ease of operation deteriorates
Solution Approach 1:
The cam members are designed to be manually operable by users without requiring tools or complex procedures. Each cam member can be rotated to engage with the support bracket at desired positions, and the headrest assembly can be pivoted to different angles. This self-adjusting capability provides high adaptability while keeping the operation simple and intuitive.

AI summary
A seating structure includes a base, a seat supported by the base, and a backrest having a frame and a suspension material supported by the frame. The frame includes an upper end and a lower end opposite the upper end. The seating structure also includes an upper thoracic support assembly supported by the frame adjacent the upper end. The upper thoracic support assembly including a thoracic support pad positioned between the frame and the suspension material. The thoracic support pad configured to engage the suspension material to support an upper thoracic region of a user.
