Portable spring mattress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable spring mattresses do not effectively allow for support and compact rolling due to the lack of selectively collapsible hinge springs, making them inefficient for easy transportation and storage.
Innovation Solution
A mattress assembly with a plurality of internal hinged spring members that can be selectively folded into a compressed state, allowing the mattress to be rolled into a compact form for travel, using a ratchet mechanism to maintain the collapsed configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional spring mattresses are used, then support function is maintained, but portability and storage efficiency deteriorate due to inability to collapse
Solution Approach 1:
The spring members are designed to be selectively collapsible between an extended configuration for providing support and a compressed configuration for portability. This dynamic transformation allows the mattress to adapt between its support function and portable state, resolving the contradiction between maintaining support reliability and achieving ease of transport.
Solution Approach 2:
The mattress is divided into multiple independent spring members that can be individually collapsed. This segmentation allows each spring to be compressed independently, enabling the entire mattress to be rolled into a compact form while maintaining the capability to provide support when extended.
2Ease of operation
If springs are made collapsible for portability, then ease of transportation improves, but structural complexity increases
Solution Approach 1:
The spring members are designed to be self-collapsing through their inherent hinge mechanism. When force is applied to one end, the hinge allows the spring to collapse automatically without requiring complex external mechanisms or multiple components, thus achieving ease of transportation while minimizing structural complexity.
Solution Approach 2:
The spring members utilize a flexible hinge design that allows the spring to bend and collapse into a compact configuration. This flexible hinge structure provides the necessary mobility for portability while maintaining a simple and economical construction, avoiding the need for complex mechanical systems.
3Reliability
If multiple spring members are used for support, then support quality improves, but difficulty of compression and rolling increases
Solution Approach 1:
Each spring member is designed with selective collapsibility, allowing them to transition dynamically between extended and compressed states. This dynamic property enables multiple springs to be compressed together into a compact rolled configuration while maintaining their ability to provide quality support when extended.
Solution Approach 2:
The flexible hinge mechanism in each spring member allows for easy compression and rolling of multiple springs into a compact form. This hinge design reduces the difficulty of compression by enabling the springs to bend and fold smoothly, while still maintaining structural integrity for providing support when in use.

AI summary
A portable spring mattress including a mattress assembly and a spring assembly. The mattress assembly includes a top layer and a bottom layer made of a pliable comfortable foam that is configured to support and absorb the weight of a user. Spring assembly includes a plurality of collapsible members and a plurality of torsion spring hinges, wherein the plurality of collapsible members is attached between the top layer and the bottom layer. The plurality of collapsible members include a plurality of torsion spring hinges that are actuated by means of a lever, thereby the user may actuate said lever for collapsing said plurality of collapsible members to reduce the size and fold the mattress assembly for transporting and storing. The lever may be actuated in an opposite direction to return the plurality of collapsible members to its original position to receive the user.
