Air cushion bed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Air cushion beds lack sufficient support, causing users to fall, and existing solutions do not provide a convenient and effective way to address this issue.
Innovation Solution
The air cushion bed incorporates an annular belt body and longitudinal belt bodies for multi-point support, with a fabric layer for comfort, and a pump air device for efficient inflation, including both manual and electric options, along with anti-slip members for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If no supporting body is added to the air cushion bed, then the structure remains simple, but the supporting effect is insufficient causing users to fall
Solution Approach 1:
The supporting body is divided into multiple longitudinal belt bodies (at least three) that are independently arranged between the upper and lower air cushions. Each belt body provides localized support, and together they create a distributed support system that prevents user collapse while maintaining structural simplicity through modular design
Solution Approach 2:
The belt bodies are constructed from flexible belt materials that can conform to the air cushion structure while providing mechanical support. The flexible nature allows the supporting elements to integrate seamlessly with the inflatable air cushions, adding strength without rigid structural complexity
2Strength
If multiple longitudinal belt bodies are used for support, then the supporting effect is improved, but the volume of internal gas increases reducing inflation efficiency
Solution Approach 1:
The support structure is segmented into multiple thin longitudinal belt bodies rather than one large solid structure. This segmentation allows gas to flow through and around the belts during inflation, maintaining high inflation efficiency while the distributed arrangement of multiple belts provides enhanced longitudinal supporting force
Solution Approach 2:
The belt bodies are designed to work within the pneumatic system of the air cushion bed, allowing air to pass through during inflation. The belts are inflated alongside the air cushions, using the same gas supply system, which maintains inflation efficiency while the pressurized belts provide the necessary longitudinal support
3Strength
If the annular belt body is connected to air cushions, then edge support is provided, but the device complexity increases
Solution Approach 1:
The annular belt body is merged with the longitudinal belt bodies and the air cushion structure to form an integrated support system. The annular belt connects to the longitudinal belts at regular intervals, creating a unified network that provides both edge support and distributed longitudinal support without requiring separate complex mechanisms
Solution Approach 2:
The annular belt body serves multiple functions: it provides edge support, connects the longitudinal belt bodies together, and reinforces the overall structure. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity while achieving comprehensive edge support
