Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing body support devices, such as air mat devices, face challenges in accurately determining the state of a user's body, particularly in distributing pressure evenly to prevent intense pressure points that can worsen blood flow.
Innovation Solution
A body state determination device that includes a detection unit to measure pressure distributions across different body regions and a determination unit to compare these distributions, allowing for accurate assessment of body states like kyphosis and lower limb contracture, and adjusting the air cell configuration to adapt to the user's body shape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If support cells are arranged between the mat unit and base to distribute body pressure, then pressure distribution is improved, but measurement precision of body state is insufficient
Solution Approach 1:
The mat unit is divided into multiple air cells that can be independently controlled, allowing segmentation of pressure application to different body regions. This enables both pressure distribution to prevent intense pressure points and accurate measurement of body state through individual cell pressure sensing.
Solution Approach 2:
The air cells serve multiple functions: they provide pressure distribution to prevent blood flow impairment, act as sensors to detect body pressure distributions, and enable body state determination through comparative analysis of pressure data from multiple cells.
2Measurement precision
If multiple pressure distributions are detected and compared to accurately determine body state, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The air cells are designed to serve dual purposes as both pressure distribution elements and pressure sensing elements. This eliminates the need for separate sensor systems, reducing device complexity while maintaining high measurement precision through comparative analysis of pressure distributions.
Solution Approach 2:
The air cells perform self-measurement by detecting their own internal pressure changes when in contact with the user's body. This self-service capability simplifies the overall system architecture while enabling accurate body state determination through multiple pressure distribution measurements.
