Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If conventional compression springs are used, then strong elasticity is achieved through metal wire coiling, but the elasticity is fixed and non-adjustable after formation, and the spring occupies large space when compressed

Engineering Contradiction:
ImproveelasticityVSAvoidelasticity adjustability
Core Design Contradiction:
StrengthVSAdaptability or versatility

Solution Approach 1:

The patent replaces traditional metal coil springs with gas-filled chambers that use pneumatic pressure to provide elastic support. The gas chambers can be inflated or deflated to adjust the elasticity level, allowing the mattress to adapt to different user preferences and body types. This pneumatic system eliminates the fixed elasticity of metal springs while maintaining strong supportive force.

Inventive Principle:
Principle #29Pneumatics and hydraulics

Solution Approach 2:

The patent changes the physical parameter of gas pressure within the chambers to adjust elasticity. By controlling the amount of gas injected into each chamber, the system can dynamically modify the firmness and elastic properties of the mattress surface. This parameter adjustment capability directly addresses the non-adjustable nature of conventional springs.

Inventive Principle:
Principle #35Parameter changes

2Strength

If conventional compression springs are used, then strong elasticity is provided, but moisture generated by human body or in the environment gathers and cannot be removed through air convection

Engineering Contradiction:
ImproveelasticityVSAvoidmoisture accumulation
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The patent employs mesh-like or porous partition walls between gas chambers that allow air circulation while maintaining structural integrity. These porous structures enable moisture vapor to pass through and be expelled from the mattress interior, preventing condensation and bacterial growth. The porous design maintains elasticity through gas pressure while simultaneously solving the moisture trapping problem of solid-walled spring systems.

Inventive Principle:
Principle #31Porous materials

Solution Approach 2:

The pneumatic gas chambers create internal air flow paths that facilitate convective removal of moisture. The pressurized gas environment promotes air circulation within the chambers, carrying moisture vapor away from the sleeper's contact surface and preventing the stagnant, humid conditions that occur in traditional innerspring mattresses.

Inventive Principle:
Principle #29Pneumatics and hydraulics

3Strength

If gas spring with piston and hollow cavity is used, then spring effect is achieved, but the structure becomes complex with high requirement on inter-part fitting

Engineering Contradiction:
Improvespring effectVSAvoidstructure complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The patent uses flexible, sealed membrane structures to contain the gas chambers, eliminating the need for rigid pistons, cylinders, and complex mechanical assemblies. The flexible shells themselves provide the spring effect through gas compression and expansion, dramatically simplifying the structure. This membrane-based approach removes multiple moving parts and reduces assembly complexity while maintaining the desired elastic functionality.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The patent extracts and removes the complex piston-cylinder mechanism from traditional gas springs, retaining only the essential gas-containing chamber function. By eliminating unnecessary mechanical components like pistons, seals, and connecting rods, the design achieves spring effect with minimal structure, reducing both complexity and manufacturing difficulty.

Inventive Principle:
Principle #2Taking out (Extraction)

4Strength

If gas spring with piston is used, then spring effect is achieved, but deformation stroke is insufficient and hardness adjustment range is small

Engineering Contradiction:
Improvespring effectVSAvoiddeformation stroke
Core Design Contradiction:
StrengthVSLength of moving object

Solution Approach 1:

The patent divides the mattress into multiple independent gas chambers separated by partition walls. Each chamber can be independently adjusted in terms of gas pressure and volume, allowing for fine-grained control over local hardness and deformation characteristics. This segmentation enables both large overall deformation stroke and precise hardness adjustment across different zones of the mattress.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements a dynamic adjustment system where gas pressure in each chamber can be modified in real-time based on user needs. The chambers can transition between highly compressed and fully expanded states, providing a wide deformation stroke range. The hardness can be dynamically changed by adjusting gas flow, offering a broad adjustment range that adapts to different sleeping positions and user preferences.

Inventive Principle:
Principle #15Dynamics
