Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Long-distance airline or bus travel can lead to health issues such as blood clots and discomfort due to prolonged sitting, and existing seats are often uncomfortable, leading to frustration and inability to stay seated for extended periods.
Innovation Solution
A portable memory foam seat cushion with a seat and back portion that can be rolled up for ease of portability, featuring straps for secure carrying and adjustable handles, providing comfort and support when used on standard seats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional seat cushion is used, then comfort is improved, but portability deteriorates
Solution Approach 1:
The cushion is divided into multiple independent layers including a quilted cover layer, memory foam layer, gel layer, and high-density foam base layer. Each layer performs a specific function while together they provide comprehensive comfort, allowing the cushion to be both comfortable and portable through modular construction
Solution Approach 2:
The cushion employs a nested structure where the quilted cover encloses the memory foam layer, which in turn contains the gel layer, all situated within the high-density foam base. This nested arrangement maximizes comfort functionality while minimizing overall volume for portability
2Ease of operation
If a thick cushion is used, then comfort is improved, but portability deteriorates
Solution Approach 1:
Different layers of the cushion have different thicknesses and densities optimized for their specific functions. The high-density foam base provides structural support with moderate thickness, while the gel and memory foam layers provide pressure relief with varying local thicknesses, and the quilted cover adds comfort without significant bulk, achieving comfort without excessive volume
Solution Approach 2:
The cushion combines multiple materials with different properties: high-density foam for structural support, memory foam for pressure distribution, gel for temperature regulation and additional cushioning, and quilted fabric for comfort. This composite structure provides comprehensive comfort functionality while maintaining a compact, portable form factor
