Inflatable mattress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inflatable mattresses face challenges with structural stability and convenience due to the limitations of pull tabs, which create larger cavities and require multiple air nozzles for inflation, affecting the distribution of stress and air circulation.
Innovation Solution
An inflatable mattress design featuring a wave-like route for a pull rope that connects the upper and lower surrounding sheets, providing more uniform support and dispersing stress points, along with additional structural elements like mesh layers and weight blocks to enhance stability and air circulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a pull tab is arranged inside the inflatable mattress to reinforce strength and reduce bulges, then structural stability is improved, but two large cavities are formed requiring multiple air nozzles for inflation, increasing device complexity
Solution Approach 1:
The pull rope integrates multiple functions: it reinforces structural stability while simultaneously serving as the inflation pathway. The pull rope connects the upper and lower surrounding sheets and includes an air nozzle, combining the structural reinforcement element with the inflation function into a single integrated component, eliminating the need for separate air nozzles
Solution Approach 2:
The pull rope performs multiple functions within a single component: it provides structural reinforcement to prevent bulges, acts as a connecting element between upper and lower sheets, and serves as the inflation channel with an integrated air nozzle, making the system more efficient without adding complexity
2Stability of the object's composition
If a pull tab is used to provide vertical drawing force for stability, then structural stability is improved, but the limited connection points affect convenience and overall stability
Solution Approach 1:
The pull rope is divided into multiple segments with connection points distributed along its length rather than concentrated at a single location. These segmented connection points are arranged to provide uniform support across the mattress surface, improving both stability and convenience by distributing the structural load
3Stress or pressure
If the pull rope is arranged in a wave-like route to disperse stress points, then uniform support is improved, but the structural complexity increases
Solution Approach 1:
The pull rope is configured in a wave-like curved route between the upper and lower surrounding sheets instead of a straight line. This curved configuration naturally disperses stress points along the rope's length and provides more uniform support across the mattress surface, while the wave pattern is achieved through simple routing rather than complex structural elements
