Solution Overview

Problem

Existing elastic mattresses face issues with springs that interlock, leading to uneven deformation and support, require a rigid sponge for integrity, are difficult to clean, and pose health risks due to sponge materials.

Innovation Solution

An elastic module with springs in multiple layers, where each spring is independently connected using flexible material sleeves and balancing layers, allowing for independent elasticity and reduced interference.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If springs are rigidly connected with each other to prevent entanglement, then reliability is improved, but device complexity increases and ease of operation deteriorates

Engineering Contradiction:
Improvespring entanglement preventionVSAvoidconnection structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent divides the spring system into multiple independent layers, with each layer containing springs that are independently wrapped and connected. This segmentation allows each layer to function autonomously while maintaining overall structural integrity, preventing entanglement without requiring complex rigid connections between all springs.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transitions from a two-dimensional planar arrangement of springs to a three-dimensional multi-layer structure. By stacking springs in multiple layers and connecting them laterally through the balancing layer, the system gains an additional spatial dimension for organization, reducing entanglement while maintaining connection simplicity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If springs are arranged in low density to prevent entanglement, then reliability is improved, but manufacturing precision deteriorates

Engineering Contradiction:
Improvespring entanglement preventionVSAvoidspring arrangement
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

By segmenting springs into multiple layers with staggered arrangements, the patent achieves reliable entanglement prevention without requiring low overall density. Each layer can be independently manufactured and assembled, improving manufacturing precision while maintaining reliability.

Inventive Principle:
Principle #1Segmentation

3Reliability

If sponge is used to connect springs and provide support, then reliability is improved, but object-generated harmful factors worsen due to cleaning difficulties and health risks

Engineering Contradiction:
Improvespring connection and supportVSAvoidhealth risks from sponge
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent extracts and removes the sponge component from the mattress structure, replacing it with a flexible material balancing layer that connects springs laterally. This elimination of sponge removes the source of health risks and cleaning difficulties while maintaining the necessary support and connection functions through the flexible balancing layer.

Inventive Principle:
Principle #2Taking out (Extraction)

4Strength

If springs are fixed on rigid base plate to provide support, then strength is improved, but adaptability deteriorates as springs cannot follow body position variations

Engineering Contradiction:
Improvemattress supportVSAvoidadaptability to body position
Core Design Contradiction:
StrengthVSAdaptability or versatility

Solution Approach 1:

The patent replaces the rigid base plate with a flexible material balancing layer that provides lateral connection between springs while allowing dynamic movement. This dynamic structure enables springs to independently respond to body position variations while maintaining overall structural strength and support.

Inventive Principle:
Principle #15Dynamics

5Strength

If multiple layers of springs are stacked to improve support, then strength is improved, but device complexity increases

Engineering Contradiction:
Improvemattress supportVSAvoidmulti-layer structure
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The patent segments the spring system into multiple layers with staggered arrangements, where each layer is independently wrapped and connected through the flexible balancing layer. This segmentation provides enhanced support strength while keeping each layer simple and manageable, reducing overall device complexity compared to a monolithic multi-layer structure.

Inventive Principle:
Principle #1Segmentation
