Multi-Layer Seating Support Structure for Localized Load Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional seating structures often fail to provide adequate support and comfort for a wide range of body shapes and sizes, leading to discomfort due to their inability to conform to localized body irregularities.
Innovation Solution
A multi-layered support structure comprising cooperative layers of support rails, spring elements, and pixels, which are designed to provide flexible and durable support by accommodating both macro and micro load characteristics, ensuring maximum comfort and adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a seating structure is designed to conform to general body shapes, then global comfort is improved, but it cannot adapt to localized body irregularities resulting in discomfort
Solution Approach 1:
The seating structure is divided into multiple independent layers (global layer with support rails, local layer with spring elements, and top mat layer with pixels) that can independently deflect and adapt to different aspects of body contact, allowing simultaneous accommodation of general body shapes and localized irregularities
Solution Approach 2:
Different layers are designed with distinct properties: the global layer provides macro support for overall body shape, while the local layer with spring elements and top mat layer with pixels provide micro-level adaptation to localized body irregularities, ensuring each region of the seating structure has appropriate characteristics for its specific function
2Adaptability or versatility
If multiple layers are added to improve adaptability, then comfort increases, but device complexity increases
Solution Approach 1:
The seating structure employs a nested multi-layer configuration where the local layer with spring elements is positioned within the global layer framework, and the top mat layer with pixels is positioned within the local layer, creating a compact hierarchical structure that maximizes adaptability while minimizing overall complexity

AI summary
A method for manufacturing a multi-layered support structure provides ergonomic, adaptable seating support. The method providing multiple cooperative layers to maximize global comfort and support while enhancing adaptation to localized variations in a load, such as in the load applied when a person sits in a chair. The cooperative layers each include elements such as pixels, springs, support rails, and other elements to provide this adaptable comfort and support. The method for manufacturing the multi-layered support structure uses aligned material to provide a flexible yet durable support structure. Accordingly, the method provides a multi-layered support structure, which provides maximum comfort for a wide range of body shapes and sizes.
