Problem

Conventional beds suffer from issues such as low durability of filling materials, inconvenient transportation and movement, single-function mattresses, difficulty in hygiene maintenance, and poor structural stability.

Innovation Solution

A sponge bed design featuring a bed body and headboard filled with memory sponge material, a multi-layered mattress with antibacterial and thermal conductivity layers, and a stable connection system using T-shaped docking protrusions and grooves, along with weight reduction perforations for ease of movement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If traditional spring and sponge fillers are used in beds, then initial comfort is provided, but service life is limited and material distortion occurs over time

Engineering Contradiction:
Improveservice life of bed fillerVSAvoidsupport performance stability
Core Design Contradiction:
Duration of action of moving objectVSReliability

Solution Approach 1:

The patent uses memory foam material as a composite material that combines the comfort properties of traditional sponge with shape memory and slow recovery characteristics. This composite material maintains its support performance over time without the distortion and collapse issues of conventional spring and sponge fillers, thereby extending service life while preserving reliability.

Inventive Principle:
Principle #40Composite materials

2Stability of the object's composition

If complex bed frame structure is used, then structural stability is achieved, but transportation and movement become inconvenient

Engineering Contradiction:
Improvebed frame stabilityVSAvoidtransportation convenience
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The bed frame is divided into separable components including the bed body, headboard, and mattress that can be easily assembled and disassembled. The connection structures use simple joining mechanisms that maintain structural stability when assembled but allow convenient separation for transportation and movement, resolving the contradiction between stability and ease of operation.

Inventive Principle:
Principle #1Segmentation

3Temperature

If single-layer mattress structure is used, then manufacturing simplicity is maintained, but temperature regulation capability is insufficient

Engineering Contradiction:
Improvemattress temperature regulationVSAvoidmattress structure complexity
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The mattress employs a multi-layer composite structure with different material layers serving specific functions: a cool-feeling fabric layer for heat dissipation, an insulation layer for warmth retention, and a velvet layer for comfort. This composite construction provides effective temperature regulation by allowing users to select appropriate layers for different seasons, while the modular design keeps manufacturing manageable.

Inventive Principle:
Principle #40Composite materials

4Ease of manufacture

If traditional mattress materials are used, then ease of manufacture is maintained, but hygiene maintenance becomes difficult and bacteria breeding occurs

Engineering Contradiction:
Improvemattress manufacturing simplicityVSAvoidbacteria and odor accumulation
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The mattress incorporates porous material structures that allow for breathability and moisture wicking, preventing the accumulation of moisture that promotes bacterial growth. The porous design maintains ease of manufacture using conventional foam processing techniques while effectively addressing hygiene concerns through improved air circulation and reduced moisture retention.

Inventive Principle:
Principle #31Porous materials

5Adaptability or versatility

If combination bed structure is used, then functionality is enhanced, but connection stability deteriorates over time

Engineering Contradiction:
Improvebed combination functionalityVSAvoidconnection stability
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The combination bed structure uses standardized, separable connection interfaces between the bed body, headboard, and mattress. These segmented connections employ simple joining mechanisms that maintain stable connections when assembled while allowing easy reconfiguration and disassembly, preventing the loosening and instability that occurs in traditional combination structures over time.

Inventive Principle:
Principle #1Segmentation
