Solution Overview

Problem

Existing elastic mattresses offer limited customization options for softness and hardness, failing to meet individual user needs, particularly for those with lumbar issues, leading to discomfort due to excessive softness or hardness in localized areas.

Innovation Solution

An elastic mattress with multiple groups of spring modules, each comprising spring members with varying elasticities and hardnesses, connected by detachable structures, allowing for customizable partitioning of softness and hardness to adapt to different body parts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single elasticity is used throughout the elastic mattress, then the manufacturing process is simple, but the comfort level for users with specific needs (e.g., lumbar issues) is insufficient

Engineering Contradiction:

Improvecustomization of softness and hardnessVSAvoidstructure of spring modules

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The elastic mattress is divided into multiple spring modules, each containing spring members with different elasticities. These modules can be independently configured and assembled to create customized softness and hardness distributions across different sections of the mattress, directly addressing the need for localized comfort customization.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different sections of the mattress are equipped with spring members having different elasticity characteristics. For example, the lumbar region can use softer spring members while other areas use harder ones, allowing each local area to be optimized for its specific functional requirements and user needs.

Inventive Principle:

Principle #3Local quality

2Adaptability or versatility

If the elastic mattress uses fixed elasticity, then the device complexity is low, but the comfort level and rest quality are limited

Engineering Contradiction:

Improveselection of elasticity optionsVSAvoidconfiguration of spring members

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mattress transitions from a static, fixed-elasticity design to a dynamic, customizable configuration. Users can select and assemble different spring module combinations based on their specific needs, allowing the mattress to adapt its characteristics rather than being locked into a single elasticity profile.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The spring modules are designed with universal connecting structures that allow the same basic component to serve multiple functions and be configured in various arrangements. This enables a single set of modular components to create multiple elasticity configurations, increasing versatility without proportionally increasing overall complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If the elastic mattress has constant elasticity on one side, then the manufacturing process is simple, but it causes soreness for users requiring localized softness or hardness

Engineering Contradiction:

Improvepartitioning of softness and hardnessVSAvoidassembly of different spring modules

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The mattress is segmented into multiple spring modules that can be independently manufactured and then assembled. Each module contains spring members with specific elasticity characteristics, allowing localized customization of softness and hardness while maintaining relatively simple individual manufacturing processes.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Connecting structures serve as intermediaries between different spring modules, facilitating their assembly into customized configurations. These standardized connection mechanisms simplify the manufacturing and assembly process by providing uniform interfaces between modules with different elasticity characteristics.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

An elastic mattress partitioning softness and hardness comprises at least two groups of spring modules with different elasticities and hardnesses. An inner side of each of the spring modules comprises a plurality of spring members that are spliced together, and each of the at least two groups of the spring modules comprises the plurality of spring members with at least one elasticity and hardness. Each of the spring modules defines an interlaced or array arrangement by the plurality of spring members through the connecting structures, and the spring modules with the different hardnesses in the elastic mattress are assembled in any section in the elastic mattress. A hardness of one or more of the plurality of spring members disposed in an edge section of the elastic mattress is greater than a hardness of one or more of the plurality of spring members in another section of the elastic mattress.
