Mobile foldable shower mattress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foldable shower mattresses require lifting and unfolding, occupy significant space when stored, and are inconvenient for bathing disabled individuals, especially in healthcare settings.
Innovation Solution
A mobile foldable shower mattress design featuring side plates hingedly connected to bottom plates, with damping hinges and waterproof fabrics, allowing for easy assembly and disassembly, and reduced storage volume through folding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the shower mattress walls are made foldable, then the storage volume is reduced, but the walls still occupy significant space when folded and require manual lifting and unfolding operations
Solution Approach 1:
The shower mattress incorporates a dynamic rolling mechanism where the side plates can be rolled up and down relative to the bottom plates through hinges. This allows the mattress to transition from an extended bathing configuration to a compact rolled-up storage configuration, significantly reducing storage volume while eliminating the need for manual lifting and complex unfolding operations.
Solution Approach 2:
The shower mattress is divided into segmented components including multiple bottom plates and side plates connected by hinges. This segmentation enables independent rolling and folding of different sections, allowing the structure to be compacted efficiently for storage while maintaining ease of operation during deployment.
2Volume of moving object
If the shower mattress is designed to be compact for storage, then space occupation is reduced, but the structure becomes more complex requiring multiple components
Solution Approach 1:
The hinge connections serve multiple functions: they enable the side plates to be hinged for rolling motion, provide structural connection between bottom and side plates, and allow the mattress to maintain its shape during both extended and folded states. This multi-functionality reduces the need for additional complex mechanisms while achieving compact storage.
Solution Approach 2:
The waterproof fabric covering acts as a flexible shell that conforms to the changing geometry of the mattress structure. When the rigid plates are rolled or folded, the flexible fabric wraps around them, maintaining the enclosed bathing space while allowing compact configuration for storage without requiring additional rigid structural elements.

AI summary
A mobile foldable shower mattress includes a main body, an upper waterproof fabric, and a lower waterproof fabric. The main body includes at least two bottom plates, a plurality of side plates, and a plurality of damping hinges. The at least two bottom plates are arranged side by side. The plurality of side plates are located around the at least two bottom plates and hingedly connected to the corresponding bottom plates. An accommodating room is enclosed by the plurality of side plates and the at least two bottom plates. The plurality of damping hinges are each disposed between a corresponding one of the bottom plates and a corresponding one of the side plates.
