Mattress Side Rail Airflow Structure for Heat and Moisture Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mattress assemblies, particularly those with memory foam layers, suffer from poor ventilation due to high density, leading to heat buildup and discomfort, while side rail assemblies obstruct airflow, further increasing heat and moisture retention.
Innovation Solution
Incorporating air channels and orifices in the side rail assemblies and mattress layers to facilitate airflow from the inner core to the exterior, using high airflow foam with an open cell structure to enhance ventilation and dissipate heat and moisture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If high density foam is used in mattress assemblies, then load-bearing capability and structural strength are improved, but ventilation and airflow are blocked, leading to heat buildup
Solution Approach 1:
The patent employs open cell foam structures with controlled porosity that allow air permeation while maintaining structural integrity. The foam is engineered with interconnected cells that create pathways for airflow, enabling heat dissipation without sacrificing the load-bearing capabilities required for mattress support functions.
2Ease of operation
If memory foam layers are added to improve comfort, then user comfort is enhanced, but airflow is further restricted, increasing heat and moisture retention
Solution Approach 1:
The patent utilizes composite foam structures combining different foam types and densities in layered configurations. By integrating memory foam layers with open cell foam layers having different airflow characteristics, the design achieves both comfort enhancement through pressure relief and improved ventilation through strategic material placement and interlayer air channel formation.
3Stability of the object's composition
If side rail assemblies are made solid for edge support, then structural stability is improved, but they act as air dams blocking airflow out of the mattress
Solution Approach 1:
The side rail assemblies incorporate localized airflow channels and perforations at specific positions where air damming occurs. This allows the majority of the side rail structure to maintain solid construction for edge support stability, while specific local regions are modified to permit air passage, enabling heat and moisture to escape from the mattress interior without compromising overall structural integrity.
4Temperature
If reticulated foam is used to increase airflow, then ventilation is improved, but the foam becomes weak and loses load-bearing capability
Solution Approach 1:
The patent employs foam structures with controlled cell size distributions and adjusted porosity parameters that optimize the balance between airflow and mechanical strength. By carefully selecting and tuning foam parameters such as cell density, cell wall thickness, and open cell percentage, the design achieves sufficient air permeability for heat dissipation while maintaining the structural strength necessary for mattress support functions.

AI summary
A mattress assembly includes an inner core comprising a base core layer comprising planar top and bottom surfaces, and at least one comfort layer comprising planar top and bottom surfaces disposed on the top surface of the base core layer; a side rail assembly disposed about a perimeter of the inner core; and a plurality of air channels extending from a central region of the inner core to the side rail assembly configured to permit the flow of fluid from and to the inner core.
