Inflatable bed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inflatable beds with internal tensioning beams suffer from poor stability and severe outward expansion, particularly when the height is high, leading to instability and an uneven appearance, and the current connection methods result in low processing efficiency and increased costs.
Innovation Solution
The inflatable bed features non-closed annular upper and lower diagonal tensioning beams with gaps, connected via weld seams forming a channel for gas communication, allowing simultaneous inflation of central and edge chambers, and a one-time welding process for stable connection to the surrounding sheet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If four upper diagonal tensioning beams and four lower diagonal tensioning beams are connected one by one, then the stability of the inflatable bed is improved and the surrounding sheet expansion is limited, but the processing efficiency is reduced and processing cost increases
Solution Approach 1:
The patent merges the connection process of multiple diagonal tensioning beams into a single integrated operation. The beams are pre-assembled into a complete diagonal support structure before being connected to the inflatable bed body in one go, transforming multiple sequential connection operations into a single combined operation, thereby improving processing efficiency while maintaining the stability-enhancing function
Solution Approach 2:
The diagonal tensioning beams are pre-assembled and pre-positioned into a complete structural configuration before being attached to the inflatable bed. This preliminary assembly allows the entire diagonal support system to be installed as a unified component, reducing the number of connection steps required during the main assembly process and improving overall processing efficiency
2Shape
If four upper diagonal tensioning beams and four lower diagonal tensioning beams are connected one by one, then the surrounding sheet outward expansion is limited, but the processing cost increases
Solution Approach 1:
The patent combines multiple diagonal tensioning beams into a pre-assembled unit structure, allowing the entire diagonal support system to be attached in one operation rather than connecting each beam individually. This merging approach reduces labor time, simplifies the manufacturing process, and lowers processing costs while effectively limiting the surrounding sheet expansion to maintain its flat appearance
3Ease of operation
If internal tensioning beams are disposed to connect top sheet and bottom sheet, then basic use functions are met, but the inflatable bed has poor stability and easy rollover when height is high
Solution Approach 1:
The patent transitions from vertical tensioning (connecting top and bottom sheets directly) to diagonal tensioning (connecting corners of the top sheet to opposite corners of the bottom sheet). This dimensional change in the arrangement of tensioning beams creates a more stable structural configuration that resists rollover, while still maintaining the basic support function of connecting the top and bottom sheets

AI summary
An inflatable bed is provided, which includes an inflatable chamber surrounded by a top sheet, a bottom sheet, and a surrounding sheet; and a plurality of internal tensioning members connecting the top sheet and the bottom sheet and provided in the inflatable chamber. The inflatable bed further includes a non-closed annular upper diagonal tensioning beam and a lower diagonal tensioning beam provided in the inflatable chamber. An upper end of the upper diagonal tensioning beam is connected to the top sheet, and a lower end of the upper diagonal tensioning beam is connected to the surrounding sheet, thereby forming an upper edge frame. An upper end of the lower diagonal tensioning beam is connected to the surrounding sheet, and a lower end of the lower diagonal tensioning beam is connected to the bottom sheet, thereby forming a lower edge frame.
