Electrospinning Mixture Section for Uniform Fiber Density
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The electrospinning process often results in deposited bodies with regions of varying fiber density, leading to weak bonding between high and low density areas, which can cause damage during exfoliation from the collection surface, as exfoliation tends to occur between low and high density regions rather than between the high density region and the surface.
Innovation Solution
An electrospinning apparatus with a processing section that forms a mixture section by mixing fibers from high and low density regions, ensuring they are tightly bonded, allowing for safe exfoliation without damaging the deposited body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrospinning deposits fibers on a member to form a deposited body, then the deposited body can be used after exfoliation, but the varying fiber density creates weak bonding between high and low density regions causing damage during exfoliation
Solution Approach 1:
The patent changes the physical parameters of fiber deposition by controlling electrospinning conditions to create a gradient structure where fiber density transitions smoothly from high to low density regions, eliminating abrupt boundaries that cause weak bonding and damage during exfoliation
Solution Approach 2:
The patent creates different fiber density zones (high density region adjacent to member, low density region away from member) with specific local properties, where each region has optimized characteristics for its function while maintaining strong interfacial bonding through controlled gradient transition
2Ease of operation
If the deposited body is exfoliated from the member, then it can be used as a standalone structure, but exfoliation occurs between low and high density regions rather than between the high density region and the surface, causing damage
Solution Approach 1:
The patent performs preliminary action by pre-forming a mixture section withgradual density transition during the electrospinning process itself, before exfoliation occurs. This pre-established gradient structure ensures that when exfoliation happens, the stress is distributed evenly through the mixture section rather than concentrating at sharp density boundaries, preventing structural damage

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents damage to the deposited body during exfoliation by ensuring that the mixture section is formed, allowing for uniform removal without breaking the bond between high and low density regions.
