Inflatable Bed Chamber Segmentation to Reduce Sponge Weight and Volume
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inflatable beds are large and difficult to store due to the overall filling of sponge layers, which increases weight and volume.
Innovation Solution
The inflatable bed is divided into a first air-filled chamber with a sponge layer and a second air-filled chamber with pulling ribs, where the air pump is located, allowing for reduced sponge usage and improved storage efficiency by distributing weight and volume effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the air-filled chamber is completely filled with sponge layer to improve comfort and thermal insulation, then the comfort and thermal insulation are improved, but the weight and volume increase, causing inconvenience of storing and carrying
Solution Approach 1:
The air-filled chamber is divided into a first air-filled chamber and a second air-filled chamber arranged along the length direction. The sponge layer is filled only in the first air-filled chamber, while the second air-filled chamber contains pulling ribs and an air pump. This segmentation allows the sponge to be concentrated in the upper body area where comfort is most needed, while reducing overall sponge usage and weight.
Solution Approach 2:
The sponge layer is selectively placed in the first air-filled chamber corresponding to the upper body area, providing enhanced comfort and thermal insulation where most needed. The second air-filled chamber uses pulling ribs for lower body support, reducing the need for sponge in areas where it provides less benefit, thereby reducing overall weight.
2Temperature
If the air-filled chamber is completely filled with sponge layer to improve thermal insulation, then the thermal insulation is improved, but the volume increases, causing inconvenience of storing and carrying
Solution Approach 1:
The air-filled chamber is segmented into two parts: the first air-filled chamber with sponge layer for thermal insulation, and the second air-filled chamber with pulling ribs and air pump. This segmentation reduces the total volume required for sponge while maintaining thermal insulation in the critical upper body area.
Solution Approach 2:
Thermal insulation via sponge layer is applied locally in the first air-filled chamber corresponding to the upper body area, where thermal insulation is most needed. The second air-filled chamber relies on the air cushion and pulling ribs, reducing the overall volume occupied by sponge material.
3Stability of the object's composition
If the sponge layer is distributed throughout the entire air-filled chamber to provide uniform support, then the uniformity of support is improved, but the weight and volume increase
Solution Approach 1:
Different support mechanisms are applied to different body regions: the sponge layer in the first air-filled chamber provides soft support for the upper body, while the pulling ribs in the second air-filled chamber provide structural support for the lower body. This localized differentiation achieves effective support without requiring uniform sponge distribution throughout the entire chamber, reducing overall weight.
