Mattress with replaceable internal layers and outer cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mattresses are difficult to move or transport due to their large size and weight, and internal layers are fixedly connected, leading to infrequent replacement, environmental waste, and issues like mildew, mold, and sagging, which can cause skin allergies and reduced support over time.
Innovation Solution
A mattress design with selectively removable and replaceable internal layers and outer cover, featuring an elastic support system clamped by fixing elements and a comfort system with interchangeable components, allowing for customizable resilience and support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the internal layers are fixedly connected to the outer cover, then the structural stability is improved, but the replaceability of individual components deteriorates
Solution Approach 1:
The mattress is divided into separable modules: the outer cover and the internal layers are disconnected and can be independently removed or replaced. This segmentation allows individual components to be replaced without discarding the entire mattress, resolving the contradiction between structural stability and component replaceability.
2Strength
If the mattress is made heavy and large in volume, then the support strength is improved, but the ease of movement and transport deteriorates
Solution Approach 1:
The mattress structure is segmented into removable internal layers and an outer cover. This allows the heavy mattress to be disassembled into lighter components that can be easily moved and transported, while maintaining the support strength when assembled.
3Duration of action of stationary object
If the mattress is used for several decades, then the durability is improved, but the hygiene and comfort deteriorate due to mildew, mold, and sagging
Solution Approach 1:
The patent enables selective discarding and replacement of degraded components (internal layers or outer cover) while retaining the functional parts of the mattress. This allows users to maintain hygiene and comfort by replacing only the affected components rather than the entire mattress, extending the overall lifecycle while preventing harmful factors.
4Stability of the object's composition
If the internal layers are sewn together permanently, then the structural integrity is improved, but the environmental waste increases due to unnecessary disposal
Solution Approach 1:
The permanent sewing connection is replaced with a separable design where internal layers and outer cover can be independently removed. This segmentation prevents environmental waste by allowing replacement of only the worn components rather than discarding the entire mattress, while maintaining structural integrity when assembled.

AI summary
A mattress includes an outer cover having a bed frame and an upholstery layer; an elastic support system including a pocket-spring layer, a foam isolation pad layer, a joining fabric layer and a plurality of fixing elements; and a comfort system. The fixing elements are provided on around a perimeter of the elastic support system to clamp the pocket-spring layer, the foam isolation pad layer and the joining fabric layer together. The comfort system includes a plurality of pad layers, an inner cover and a plurality of connecting materials disposed on an undersurface of the inner cover to form a locating pattern for selectively connecting to different locations on the joining fabric layer. Since the upholstery layer, the elastic support system and the comfort system are replaceable; the mattress can provide desirable resilience and support strength to evenly disperse pressure applied by the user to the mattress.
