Rolling Foldout Cabinet Bed With Retainer Belt Mattress Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldout cabinet beds face issues with stability, comfort, safety, and ease of use due to high center of gravity, complex mechanisms, sharp edges, and inadequate mattress storage, particularly with innerspring mattresses.
Innovation Solution
A foldout cabinet bed design featuring a dual-opening mechanism with a mattress that can be held by a retainer belt to one side, allowing for safe and easy deployment with a low center of gravity, and incorporating adjustable legs and a secure mattress storage system to prevent creases and dents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the cabinet is designed with a high center of gravity to accommodate the mattress, then the mattress can be stored within the cabinet, but the cabinet becomes unstable and difficult to move
Solution Approach 1:
The patent introduces caster wheels at the base of the cabinet to enable mobility, compensating for the high center of gravity issue. This allows the cabinet to be moved easily despite having the mattress stored within, resolving the contradiction between storage capacity and stability by adding a mobility dimension.
2Reliability
If a complex mechanism is used to support the mattress and unfold the bed, then the bed can be supported during deployment, but the mechanism adds weight and points of failure
Solution Approach 1:
The patent removes the complex unfolding mechanism entirely and instead uses a simple retainer belt system to hold the mattress. The mattress is extracted from the cabinet by pulling it through the opening, eliminating heavy mechanical support structures and reducing points of failure while maintaining reliability.
3Ease of operation
If the cabinet is designed to open fully for bed access, then the bed is accessible for sitting and sleeping, but the sides can fall down by themselves requiring caution
Solution Approach 1:
The patent uses a retainer belt to preliminarily secure the mattress to the cabinet side before opening. This preliminary action prevents the mattress from falling or causing the side to collapse during the opening process, allowing full opening for accessibility without the harmful effect of unstable sides.
4Volume of moving object
If an innerspring mattress is stored in the folded configuration, then the mattress can be stored within the cabinet, but the mattress becomes damaged with creases and dents
Solution Approach 1:
The patent allows the mattress to remain in a dynamic, unfolded state during storage rather than forcing it into a folded configuration. The mattress is pulled through the cabinet opening and can be positioned to lie flat or at an angle, maintaining its surface integrity while still being stored within the cabinet space.

AI summary
A rolling foldout cabinet bed has two faces that fold out from a vertical to a horizontal position, thereby creating a surface that can be used for sleeping. When the cabinet is closed, a space within the cabinet stores a foldable innerspring, or other mattress. The two faces can be locked together in the folded position. During deployment, an elastic belt or other retainer and hold the folded mattress to one of the faces, and can also pull the mattress out of the interior space within the bottom of the cabinet. The cabinet also has legs for supporting the faces above the ground when in the opened configuration, and can include wheels that facilitate moving the cabinet quickly and easily moved.
