Solution Overview

Problem

Existing mattresses lack sufficient ventilation outside of airflow paths, leading to inadequate breathability and comfort during use.

Innovation Solution

A mattress design featuring a breathable elastic layer, a non-breathable covering layer, and a ventilation mechanism that integrates air supply and exhaust ports to distribute airflow throughout the mattress, ensuring efficient ventilation and comfort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If non-breathable members are combined to form a flow path for efficient air supply, then air supply efficiency is improved, but breathability in areas outside the flow path deteriorates

Engineering Contradiction:

Improveair supply efficiencyVSAvoidventilation sufficiency

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The flow path is segmented into multiple independent channels formed by partition walls, allowing air to be distributed to multiple ventilation openings simultaneously. This segmentation enables efficient air supply to multiple zones without requiring a single large non-breathable structure, thereby maintaining breathability in areas outside the primary flow path.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the mattress are assigned different functions: the flow path region uses non-breathable members for efficient air supply, while areas outside the flow path maintain breathability through the elastic layer structure. This local differentiation allows each region to optimize its specific function without compromising overall ventilation.

Inventive Principle:

Principle #3Local quality

2Ease of operation

If a non-breathable covering layer is used to direct airflow, then airflow directionality is improved, but overall breathability deteriorates

Engineering Contradiction:

Improveairflow directionalityVSAvoidoverall breathability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The covering layer is designed as a thin, flexible coating film that is integrated with the elastic layer. This thin film structure provides sufficient airflow directionality to guide air through the flow path while its flexibility and integration with the elastic layer allow breathability to be maintained in areas outside the flow path, unlike rigid non-breathable covers.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The covering layer is merged with the elastic layer to form an integrated structure. This integration allows the covering layer to provide airflow directionality where needed while the elastic layer's inherent breathability is preserved in non-flow-path areas, combining the benefits of both non-breathable and breathable structures.

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If the covering layer is made fully breathable, then overall breathability is improved, but airflow directionality and efficiency deteriorate

Engineering Contradiction:

Improveoverall breathabilityVSAvoidairflow efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The covering layer exhibits local quality differentiation: it is non-breathable in the flow path region to ensure efficient, directed airflow, and breathable in areas outside the flow path to maintain overall ventilation. This spatial variation in breathability allows the system to achieve both airflow efficiency and overall breathability simultaneously.

Inventive Principle:

Principle #3Local quality

4Reliability

If ventilation openings are provided throughout the mattress, then breathability is improved, but structural integrity and airflow control deteriorate

Engineering Contradiction:

ImprovebreathabilityVSAvoidairflow control

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

Ventilation openings are segmented into specific locations along the flow path rather than being distributed throughout the mattress. This segmentation, combined with partition walls, allows breathability to be maintained at key ventilation points while simplifying airflow control by confining the flow path to specific regions rather than managing airflow across the entire mattress surface.

Inventive Principle:

Principle #1Segmentation

AI summary

To provide a mattress which can be used comfortably with good quality by distributing airflow inside. A mattress comprises a breathable elastic layer, a non-breathable covering layer covering the elastic layer, a ventilation portion that is not covered by the covering layer, and a ventilation mechanism. The covering layer is a coating film that is integrated with the elastic layer and covers the surface thereof. In the mattress air supplied to the elastic layer is discharged from the ventilation portion or air supplied to the ventilation portion is discharged from the elastic layer by the ventilation mechanism.
