Solution Overview

Problem

Existing elastic mattresses made of springs lack the ability to vary elasticity with changes in body posture due to integral assembly structures, leading to springs being subjected to uniform force and potential separation of boundaries between pressed and unpressed springs.

Innovation Solution

The use of pre-compressed springs connected by connectors at their middle portions, allowing independent movement of upper ends and preventing separation of adjacent springs, with connectors having a height greater than the spring diameter to facilitate lateral bending and extension in response to pressure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If springs are connected at upper ends to provide integral elasticity, then the mattress can withstand larger pressure, but the springs cannot deform independently according to body posture

Engineering Contradiction:

Improvepressure withstanding capabilityVSAvoidability to vary elasticity with body posture

Core Design Contradiction:

StrengthVSAdaptability or versatility

Solution Approach 1:

The connection structure is segmented into three distinct portions: upper connection portion, middle connection portion, and lower connection portion. This segmentation allows the upper ends of adjacent springs to be connected for integral support, while the middle portions remain flexible to allow independent spring deformation, and lower ends are connected for stability. The segmented connection resolves the contradiction by providing both structural integrity and adaptive flexibility.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different portions of the connection structure have different connection characteristics: the upper connection portion provides strong rigid connection for pressure distribution, the middle connection portion provides flexible connection allowing lateral bending and independent spring movement, and the lower connection portion provides stable connection. This local differentiation of connection quality enables both integral strength and local adaptability.

Inventive Principle:

Principle #3Local quality

2Stability of the object's composition

If springs are connected together in an integral structure, then the mattress provides uniform support, but the boundaries between pressed and unpressed springs separate

Engineering Contradiction:

Improvestructural integrityVSAvoidboundary separation between pressed and unpressed springs

Core Design Contradiction:

Stability of the object's compositionVSShape

Solution Approach 1:

The middle connection portion is designed to be flexible and dynamic, allowing the connection structure to adapt its shape during spring deformation. When springs are pressed, the middle connection portion allows lateral bending and relative movement between adjacent springs, preventing boundary separation while maintaining overall structural integrity through the upper and lower connection portions.

Inventive Principle:

Principle #15Dynamics

3Volume of moving object

If connectors have small height to maintain compactness, then the connection structure is compact, but the springs cannot bend laterally sufficiently

Engineering Contradiction:

Improveconnection structure compactnessVSAvoidlateral bending capability

Core Design Contradiction:

Volume of moving objectVSAdaptability or versatility

Solution Approach 1:

The height of the middle connection portion is specifically optimized within a certain range to balance compactness and lateral bending capability. By adjusting this dimensional parameter, the connection structure achieves sufficient lateral flexibility for spring independent deformation while maintaining overall compactness of the mattress structure.

Inventive Principle:

Principle #35Parameter changes
