Inflatable Sofa Chamber Layout With Selective Gas Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional inflatable sofas face issues with gas leakage and inability to maintain desired shapes due to interconnected gas chambers, leading to compromised structural integrity and user comfort.
Innovation Solution
The design incorporates a plurality of inflatable bodies connected by gas pipes, a regulation device, and a multiport valve, allowing for selective connection and gas sealing of inflatable components, such as backrests, cushions, and armrests, using connecting members and cloth covers to maintain independent inflation and deflation of each section.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple inflatable chambers are interconnected to form a complete sofa structure, then the sofa can be assembled into a functional seating arrangement, but gas leakage in one chamber compromises the entire sofa and the chambers cannot maintain independent shapes
Solution Approach 1:
The sofa is divided into multiple independent inflatable chambers (backrest chamber, cushion chamber, armrest chambers, leg rest chambers) that are physically separated by partition walls. Each chamber has its own inlet valve and exhaust valve, allowing independent inflation and deflation. This segmentation ensures that gas leakage in one chamber does not affect other chambers, resolving the reliability issue while maintaining overall sofa functionality.
2Productivity
If all inflatable chambers are connected through gas paths, then the sofa can be inflated efficiently, but the connected chambers cannot maintain their desired shapes under pressure
Solution Approach 1:
Partition walls with individual inlet valves separate each inflatable chamber, allowing independent shape control. Each chamber can be inflated to its optimal pressure and shape independently, preventing deformation caused by pressure transmission through connected gas paths.
Solution Approach 2:
The partition walls act as intermediaries between chambers, blocking direct gas flow while allowing controlled inflation through individual valves. This mediator structure enables efficient inflation of each chamber without the harmful effect of pressure equalization that would compromise chamber shapes.
3Ease of manufacture
If the sofa is designed as a single integrated inflatable structure, then manufacturing is simplified, but gas leakage affects the entire structure and repair is difficult
Solution Approach 1:
The sofa structure is segmented into multiple independent chambers with separate inlet and exhaust valves. When gas leakage occurs, users can identify the affected chamber and deflate only that specific chamber using its dedicated exhaust valve, leaving other chambers intact and functional. This segmentation dramatically improves ease of repair compared to a single integrated structure where leakage would require complete deflation and repair.

AI summary
An inflatable product includes a plurality of inflatable bodies, a plurality of connecting members, a plurality of gas pipes, a gas pump, a regulation device and a multiport valve. The connecting members are disposed on the inflatable bodies. The gas pipes are disposed outside or within the inflatable bodies to connect the connecting members. The gas pump, the regulation device and the multiport valve are connected to each other and connected to the inflatable bodies through the gas pipes and the connecting members so that the inflatable bodies can be selectively connected to or gas sealed from each other.
