Softness-adjustable mattress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current softness-adjustable mattresses lack durability and comfort, often collapsing under pressure due to the use of polyvinyl chloride (PVC) materials and are difficult to mount or dismount for handling and storage.
Innovation Solution
A softness-adjustable mattress design featuring an outer lining, inner lining, wavy cotton, and an inflation mechanism with air cushions made of a flexible impermeable material containing natural rubber, styrene butadiene rubber, and a polymer layer, which includes a first and second inflation structure to maintain shape and comfort under pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional PVC material is used for inflatable mattress, then tightness is improved, but durability and resistance to puncture/wear worsen
Solution Approach 1:
The patent applies composite materials by combining fabric substrate with PVC coating to create a multi-layer structure. The fabric layer provides tensile strength and puncture resistance, while the PVC coating provides tightness and impermeability. This composite structure resolves the contradiction between tightness and durability by integrating the advantages of both materials.
2Ease of manufacture
If vertical edges of airbed are made thin for inflation, then ease of inflation is improved, but resistance to external pressure and shape maintenance worsen
Solution Approach 1:
The patent applies curvature by designing rounded vertical edges instead of sharp corners. The curved geometry distributes external pressure more evenly along the edge structure, preventing stress concentration and collapse. This allows the edges to maintain structural integrity while remaining flexible enough for easy inflation and deflation.
3Stability of the object's composition
If mattress is designed as single integrated structure, then stability is improved, but ease of mounting and dismounting worsens
Solution Approach 1:
The patent applies segmentation by dividing the mattress into separate components: inflatable airbed sections and fabric cover sections. These segments can be independently assembled and disassembled through zippers and connection mechanisms, enabling easy mounting and dismounting while maintaining structural stability when assembled.
4Strength
If material thickness is increased to prevent puncture, then strength is improved, but flexibility and comfort worsen
Solution Approach 1:
The patent uses composite materials where the fabric substrate provides thickness and puncture resistance, while the PVC coating layer remains thin to maintain flexibility. This layered composite structure allows the mattress to be both strong against punctures and flexible enough for comfort and inflation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The mattress can be quickly mounted and dismounted, maintains shape under pressure, enhances comfort, and offers improved durability by preventing air leaks and collapse, while the flexible impermeable material ensures long-term stress resistance.
Implementation Method 1
a pair of air cushions of the same structure... the first surface, the second surface and the side surface are respectively made of a flexible impermeable material
Implementation Method 2
a pair of first spongy strips of the same structure, a spongy cushion, a second spongy strip and a third spongy strip... wavy cotton

AI summary
The disclosure discloses a softness-adjustable mattress, including an outer lining, an outer lining zipper, and a bottom lining, wherein the bottom lining is positioned on the outer lining, the outer lining zipper is positioned between the outer lining and the bottom lining, a lying-down mechanism is mounted on an inner lower wall face of the outer lining, and an inflation mechanism is mounted on the lying-down mechanism. The beneficial effects of the disclosure is having the characteristic of being quickly mounted and dismounted; through an air cushion the overall comfort degree of the mattress can be enhanced, and can prevent the integral mattress shape from collapsing; the air cushion can be inflated by the inflation controller at all times, thereby ensuring the stability of the air cushion; users can lie down on the wavy cotton, which improves the users' comfort degree and brings convenience to people's life. Moreover, the edges or corners of the air cushion of the disclosure are capable of maintaining a certain shape even under some pressure. Preferably, the air cushion of the disclosure has excellent durability.
