Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elastic mattresses with springs face challenges in assembly, elasticity adjustment, and maintenance, as they often require a rigid sponge layer that is difficult to clean and can pose health risks due to entanglement and limited durability.
Innovation Solution
The design features a modular arrangement of pre-compressed springs wrapped in flexible materials, connected by connectors to minimize interference and allow independent elasticity, eliminating the need for a thick sponge layer, and allowing for easy cleaning and comfort enhancement with optional soft materials like goose down or latex.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If springs are arranged in low density and rigidly connected, then springs do not get entangled, but the mattress loses elasticity and comfort
Solution Approach 1:
The mattress is divided into multiple independent spring units, each capable of independent deformation. The springs are segmented into individual modules that can move independently, allowing the mattress to maintain both structural stability and elastic adaptability. Each spring unit is separated by independent fabric pockets, enabling localized compression without affecting adjacent springs.
Solution Approach 2:
A flexible fabric layer is used to connect the springs instead of rigid connections. The fabric acts as a flexible membrane that allows spring movement while maintaining overall mattress integrity. This flexible connection enables the springs to deform independently without rigid constraints, preserving both stability and elasticity.
2Stability of the object's composition
If a thick sponge layer is used for support, then mattress integrity is improved, but cleaning becomes difficult and health risks increase
Solution Approach 1:
The mattress is constructed as a modular assembly of springs enclosed in separate fabric pockets, eliminating the need for a continuous thick sponge layer. Each spring unit is independently contained, allowing the fabric cover to be removed and washed without removing or cleaning the internal spring structure. This segmentation enables easy cleaning while maintaining structural integrity through the organized array of spring units.
Solution Approach 2:
A removable fabric cover serves as a flexible shell enclosing the spring units. This thin film structure replaces the traditional thick sponge layer, providing a cleanable surface while allowing the internal springs to maintain mattress support and integrity. The fabric cover can be detached for washing, solving the cleaning difficulty associated with traditional sponge mattresses.
3Stability of the object's composition
If springs are fixed on a rigid base plate, then structural stability is improved, but spring movement freedom and comfort are reduced
Solution Approach 1:
Instead of fixing springs to a rigid base plate, the springs are enclosed in flexible fabric pockets that provide structural organization without rigid constraints. The fabric acts as a flexible container that maintains mattress shape and structural stability while allowing springs to move freely within their pockets, enhancing both stability and movement freedom.
4Force
If springs are arranged in high density, then mattress support is improved, but springs interfere with each other and entangle
Solution Approach 1:
Each spring is enclosed in its own independent fabric pocket, creating segmented compartments that prevent spring-to-spring contact and entanglement. This segmentation allows springs to be arranged in high density for improved support while maintaining complete independence of each spring unit, as the fabric pockets act as individual containment chambers.

AI summary
An elastic module comprises a plurality of first springs. The plurality of first springs are arranged in an array or staggered, and a first one of the plurality of first springs and a second one of the plurality of first springs adjacent to the first one of the plurality of first springs contact or approach. Each of the plurality of first springs is a single spring that is pre-compressed and wrapped by a flexible material, and upper parts of the plurality of first springs have swingable spaces on side surfaces of the plurality of first springs. Multiple first springs of the plurality of first springs on an outer periphery of the elastic module are connected by one or more connectors or connecting parts extending from the flexible material.
