Passive Intermittent Rotating Assembly for Electrospinning Nozzle Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The viscosity and rapid volatility of macromolecular solutions in electrospinning lead to nozzle blockages, causing unstable electrospinning processes and poor fiber quality, as existing cleaning methods are labor-intensive and prone to re-depositing residues, and electrical cleaning mechanisms are unreliable in high-voltage environments.
Innovation Solution
A passive intermittent rotating assembly with a mechanical structure that uses a push member and abutment members to rotate a main wheel, adjusting the cleaning material's position without an electrical power source, ensuring stable operation in high-voltage environments by ensuring consistent contact with abutment members during movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual scraping is used to clean the spinning jet, then the cleaning process is simple, but it is labor-consuming and time-consuming with poor cleaning effectiveness
Solution Approach 1:
The cleaning system automatically adjusts the position of the cleaning material through the passive intermittent rotating assembly, eliminating the need for manual operation. The spinning jet itself drives the rotation mechanism through contact during its back-and-forth movement, making the system self-powered and highly efficient
2Extent of automation
If an electrical device is used to adjust the cleaning material position, then automated cleaning is achieved, but the electrical device breaks down in the high-voltage environment
Solution Approach 1:
The patent replaces the electrical actuator with a purely mechanical passive intermittent rotating assembly. The spinning jet's own movement drives the rotation through direct contact, eliminating electrical components from the high-voltage environment while maintaining automated cleaning functionality
Solution Approach 2:
The passive intermittent rotating assembly acts as a mechanical intermediary that transfers the motion of the spinning jet to the cleaning material. This mechanical transmission system avoids direct electrical contact while achieving the desired automated position adjustment
3Stability of the object's composition
If the same part of the cleaning material is used repeatedly, then the cleaning material remains in position, but the residues are re-attached to the spinning jet
Solution Approach 1:
The system dynamically adjusts the position of the cleaning material through intermittent rotation driven by the spinning jet's movement. This continuous positional change ensures that fresh portions of the cleaning material contact the spinning jet, preventing residue re-deposition while maintaining stable cleaning action

AI summary
A passive intermittent rotating assembly can automatically adjust a part of a cleaning material when the cleaning material cleans a spinning jet each time and that can stably operate in a high-voltage environment. The passive intermittent rotating assembly includes a plurality of first abutment members and second abutment members being arranged respectively at an inner side and outer side of the main wheel along the circumferential direction, and being separated from each other to form gaps for a push portion of a push member to pass through. Each of the first abutment members includes a first inner-side abutment portion and a first outer-side abutment portion provided for abutting against the push portion. Each of the second abutment members includes a second inner-side abutment portion and a second outer-side abutment portion provided for abutting against the push portion.
