Solution Overview
Problem
Existing sleeping equipment fails to effectively disperse body pressure uniformly when a user is in a posture where pressure differs between the right and left sides, leading to reduced comfort and potential discomfort.
Innovation Solution
The sleeping equipment features a mat body with independently inflatable and deflatable air bags arranged in the mat length direction, divided into right and left portions to adjust body pressure, allowing for alternating inflation and deflation to mimic the turning motion during sleep, and adjusts according to desired distribution rates and spine shape for optimal comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If air bags are arranged in the longitudinal direction with tubular shape, then the structure is simple and easy to manufacture, but the pressure cannot be varied between right and left sides reducing comfort when user posture is biased
Solution Approach 1:
The air bags are divided into right and left bag portions in the mat width direction, allowing independent inflation and deflation control. This segmentation enables differentiated pressure application to the right and left sides of the user's body, solving the problem of inadequate pressure distribution adaptability while maintaining the simple tubular structure configuration
Solution Approach 2:
The right and left bag portions are configured to be independently controlled, creating local quality differences in pressure application. This allows the system to adapt to user postures biased toward one side by adjusting pressure locally on each side, while the overall air bag structure remains simple and easy to manufacture
2Adaptability or versatility
If air bags are divided into right and left portions for independent control, then pressure distribution adaptability is improved, but device complexity increases
Solution Approach 1:
The air bags are divided into right and left bag portions that can be independently controlled. This segmentation provides the adaptability needed for asymmetric pressure distribution while keeping the structural complexity manageable through the use of existing tubular air bag configurations
Solution Approach 2:
The system dynamically adjusts the inflation and deflation states of right and left bag portions based on detected user posture. This dynamic control enables adaptability to various postures without requiring permanently complex structural arrangements, as the complexity is managed through controllable state changes rather than fixed structural complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enhances body pressure dispersion, improves comfort by periodically changing pressure points, facilitates blood circulation, and allows for stable sitting postures, especially in vehicles, without the need for additional rocking mechanisms, thus enhancing overall sleep and sitting experiences.
Implementation Method 1
The air bags are in an elongated shape that is long in a mat width direction. At least a part of the air bags is divided into right and left bag portions in the mat width direction, and the right bag portion and the left bag portion are configured to be independently inflated and deflated
Implementation Method 2
the right and left bag portions may be configured to be alternately inflated and deflated. Since the body of the user can thus be alternately rocked side to side in a manner similar to turning over during sleep, the part of the user's body that is subjected to the body pressure can be periodically changed
