Innovation Solution

An intelligent pressure-sensitive adjustable bedding with a latex core, airbags, and a waterproof, flame-retardant cover, equipped with a fiber sensor and air pump system for adjustable support and antibacterial properties, enhancing comfort, safety, and health.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Weight of moving object

If an airbag mattress is used, then portability and ease of carrying are improved, but structural support and air permeability deteriorate

Engineering Contradiction:
ImproveportabilityVSAvoidstructural support
Core Design Contradiction:
Weight of moving objectVSStrength

Solution Approach 1:

The patent combines airbag technology with latex foam material to create a composite structure. The latex core provides structural support and air permeability, while the airbag system adjusts to body contours, achieving both portability and structural integrity.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent divides the mattress into multiple independent airbags with different firmness levels and latex zones with varying density. This local differentiation provides targeted structural support in different areas while maintaining overall portability.

Inventive Principle:
Principle #3Local quality

2Strength

If natural latex material is used, then elasticity and comfort are improved, but fire resistance deteriorates

Engineering Contradiction:
ImproveelasticityVSAvoidfire resistance
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The patent incorporates flame-retardant agents into the latex material to convert the harmful flammability of natural latex into a beneficial fire-resistant property, while maintaining the elastic and comfortable characteristics of latex.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The patent creates a composite latex material combining natural latex with flame-retardant additives, achieving both elasticity and fire resistance through material composition.

Inventive Principle:
Principle #40Composite materials

3Reliability

If natural latex material is used, then biodegradability and environmental friendliness are improved, but antibacterial performance deteriorates

Engineering Contradiction:
Improveenvironmental friendlinessVSAvoidbacterial accumulation
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent introduces antibacterial agents into the latex material to convert the harmful bacterial accumulation issue into a beneficial antibacterial property, while preserving the biodegradable and environmentally friendly characteristics of natural latex.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The patent develops a composite latex material incorporating antibacterial additives, achieving both environmental friendliness and antibacterial performance through material composition.

Inventive Principle:
Principle #40Composite materials

4Ease of manufacture

If a single airbag structure is used, then manufacturing simplicity is improved, but adaptability to different body parts deteriorates

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidprecise support for different body parts
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent divides the mattress into multiple independent airbags that can be individually adjusted, allowing each section to adapt to different body parts while maintaining relatively simple manufacturing processes.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements a dynamic air adjustment system where airbags can be independently inflated or deflated based on detected body pressure, enabling adaptability to different body parts through controlled variation in air volume.

Inventive Principle:
Principle #15Dynamics
