Mesh Nursing Bed Fabric Balancing Skin Comfort and Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional nursing beds with mesh openings have diameters or diagonal lengths that are too small, causing skin irritation and poor air permeability, and the interweaving points are prone to detachment due to their small area and unfirm bonding.
Innovation Solution
A nursing bed featuring a net-shaped fabric with a mesh opening diameter of 2-6 times the warp and weft diameter, a thickness less than 1.1 mm, and a tensile layer for secure attachment to a bearing frame, ensuring the warp and weft do not irritate the skin and providing good air permeability, with interwoven strips and a rectangular frame for adjustable positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the mesh opening diameter is increased to improve air permeability and reduce skin irritation, then the interweaving point area becomes smaller and bonding becomes unfirm
Solution Approach 1:
The patent changes the parameter of mesh opening diameter to be 2-6 times the diameter of warp and weft, and controls the opening area ratio to 35%-78%, optimizing both air permeability and interweaving point stability without requiring smaller diameters
Solution Approach 2:
The patent uses composite materials including net-shaped fabric, tensile layer, and bearing frame to create a multi-layer structure that enhances overall bonding reliability while maintaining appropriate mesh opening dimensions for skin comfort
2Object-affected harmful factors
If the diameter of warp and weft is reduced to less than 0.55 mm to improve air permeability, then the interweaving point area becomes smaller and prone to detachment
Solution Approach 1:
The patent optimizes the diameter of warp and weft to be less than 0.55 mm while simultaneously controlling the mesh opening diameter to be 2-6 times larger, creating a balanced structure that ensures both air permeability and sufficient interweaving point area for stable bonding
Solution Approach 2:
The patent applies different quality requirements to different parts: the warp and weft have specific diameter constraints for air permeability, while the mesh opening dimensions are optimized for both breathing and interweaving point stability, creating localized optimizations throughout the structure
3Object-affected harmful factors
If the net-shaped fabric thickness is reduced to less than 1.1 mm to improve comfort, then the structural strength and secure attachment become compromised
Solution Approach 1:
The patent uses a thin net-shaped fabric layer (thickness < 1.1 mm) that provides patient comfort while relying on the tensile layer and bearing frame structure to compensate for and provide the necessary structural strength and secure attachment
Solution Approach 2:
The patent creates a composite structure where the thin net-shaped fabric is combined with a tensile layer and bearing frame, allowing the thin fabric to provide comfort while the composite structure as a whole maintains sufficient structural strength
