Elastic module comprising springs in multiple layers and elastic mattress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elastic mattresses face issues with springs that are difficult to assemble, cause simultaneous interlocking movement, fail to adjust elasticity based on body position, and have health risks due to non-detachable sponges that are hard to clean.
Innovation Solution
An elastic module comprising springs in multiple layers, where each spring is independently wrapped by flexible material sleeves and connected laterally through flexible material balancing layers, allowing independent elasticity adjustment and reduced interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If springs are arranged in low density or rigidly connected, then springs are prevented from entanglement, but the elastic mattress loses the ability to follow body position variations
Solution Approach 1:
The patent divides the spring system into multiple independent layers (first layer, second layer, third layer) with springs independently wrapped in sleeves. This segmentation allows each spring to move independently without entanglement while maintaining the ability to adapt to body contours through layered deformation
Solution Approach 2:
The patent introduces flexible material balancing layers between spring layers and flexible material sleeves around each spring as intermediary elements. These intermediaries connect springs laterally while allowing independent vertical movement, preventing entanglement while enabling body position adaptation
2Stability of the object's composition
If springs are fixed on a rigid base plate, then structural stability is improved, but springs shake left-right when compressed
Solution Approach 1:
The patent replaces the rigid base plate with a flexible material balancing layer that connects springs laterally. This flexible foundation prevents left-right shaking while allowing vertical compression, and each spring is further stabilized by its own flexible material sleeve that guides movement
Solution Approach 2:
The patent transitions from a single-plane rigid connection to a multi-layered three-dimensional structure where springs in different layers are connected through flexible balancing layers. This dimensional change allows springs to move vertically independently while lateral connections prevent excessive horizontal movement
3Stability of the object's composition
If sponge is overlapped on springs to form integral structure, then structural integrity is improved, but sponge cannot be detached and is hard to clean
Solution Approach 1:
The patent segments the mattress into detachable modular components: spring layers, flexible material balancing layers, and outer covers. Each layer can be independently removed and cleaned, maintaining structural integrity through reversible connections rather than permanent bonding
Solution Approach 2:
The patent enables easy removal and recovery of individual layers for cleaning purposes. The flexible material balancing layers and outer covers can be detached from the spring layers, allowing complete disassembly for washing and reassembly, solving the cleaning accessibility problem
4Stability of the object's composition
If springs are connected to top ends for fixing, then structural stability is improved, but complexity of fixing structure increases
Solution Approach 1:
The patent extracts the connection function from a complex top-end fixing structure and distributes it to simple lateral connections through flexible material balancing layers. The springs are connected at their sides rather than requiring complex top-end fixtures, simplifying the overall structure while maintaining stability

Function Achieved in This Case
The solution enables springs to follow body position variations, reduces interlocking, and eliminates the need for sponges, enhancing comfort and ease of cleaning.
Implementation Method 1
a flexible material balancing layer is disposed between the springs in the first layer and the springs in the second layer to connect the springs in the first layer and the springs in the second layer in a lateral direction

AI summary
An elastic module comprising springs in multiple layers comprises springs in a first layer of the multiple layers, springs in a second layer of the multiple layers, and a flexible material balancing layer. The springs in the first layer are arranged in rows and lines to form a preset shape or staggered in rows to form the preset shape, the springs in the second layer are disposed on the springs in the first layer in a same layout, and the flexible material balancing layer is disposed between the springs in the first layer and the springs in the second layer to connect the springs in the first layer and the springs in the second layer in a lateral direction.
