Ventilated Knitted Bed Sheets for Heat and Moisture Dissipation

The patent applies porous materials by incorporating ventilation ports throughout the bed sheet fabric structure. These ports create controlled porosity that allows heat and moisture to escape from between the sleeper's body and the sheet, while still maintaining the sheet's structural integrity and coverage function. This resolves the contradiction by enabling thermal and moisture dissipation without compromising the basic protective function of the bed sheet.

The patent employs composite materials by combining traditional fabric components with integrated ventilation port structures. The bed sheet consists of multiple layers including top and bottom sheets with ventilation ports formed between them, creating a composite structure that provides both coverage and active heat/moisture management. This composite approach allows the sheet to simultaneously provide basic comfort and actively regulate temperature.

The patent applies segmentation by dividing the bed sheet into multiple functional layers with ventilation ports distributed throughout. Rather than creating a single complex material, the sheet is segmented into top sheet, bottom sheet, and intermediate ventilation layers, each performing specific functions. This modular segmentation achieves effective heat dissipation while keeping individual components relatively simple and manageable.

The patent utilizes parameter changes by varying the density, size, and distribution of ventilation ports across different regions of the bed sheet. The ventilation ports are not uniformly distributed but are strategically positioned based on heat and moisture flow patterns. This parameter optimization allows effective thermal management with minimal structural complexity, adapting the fabric properties to the actual physiological needs of the sleeper.
