Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Air purification devices with high-voltage components face safety hazards due to carbonization of plastic materials from dust accumulation and potential ignition when exposed to high voltage over time.
Innovation Solution
An air filter device with a ceramic insulating column that protects high-voltage components by allowing the ion filament to induce an electric field while depositing dust and impurities on the ceramic column, which is resistant to carbonization, and preventing direct contact between the discharge net and the net base to avoid ignition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a high-voltage filament is fixed onto a plastic outer frame, then the device structure is simple and easy to manufacture, but the plastic components carbonize due to electric shock caused by high voltage after long time use, bringing potential safety hazards
Solution Approach 1:
The patent introduces a ceramic insulating column as an intermediary component between the high-voltage filament and the plastic housing. This ceramic column serves as a mediator that withstands high voltage and prevents electric shock to the plastic frame, thereby eliminating the carbonization problem while maintaining structural simplicity and ease of manufacture.
Solution Approach 2:
The patent employs composite material structure by combining ceramic insulating material with the plastic housing and metal filament. The ceramic material provides high voltage resistance and thermal stability, while the plastic provides structural support and the metal provides conductivity, creating a composite system that resolves the contradiction between ease of manufacture and safety.
2Power
If the high-voltage filament is spacingly fixed onto the outer frame, then the discharge net can be subjected to induction to produce an electric field, but dust impurities are easily absorbed onto the fixed point of the high-voltage filament on the outer frame, and after long time use the impurities and plastic are carbonized
Solution Approach 1:
The ceramic insulating column acts as an intermediary that prevents dust and impurities from directly contacting and accumulating on the plastic frame at high-voltage fixed points. The ceramic surface does not carbonize like plastic, thereby eliminating the harmful carbonization effect while allowing the electric field production function to continue operating effectively.
3Device complexity
If the high-voltage connection wire is directly exposed, then the connection is simple, but the wire absorbs dust and impurity which may bring damages and hazards
Solution Approach 1:
The ceramic insulating column serves as a protective intermediary that encloses the high-voltage connection wire. This ceramic protection prevents dust and impurities from directly contacting and damaging the wire, thereby improving reliability while maintaining connection simplicity through the integrated ceramic structure that combines insulation and protection functions.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The ceramic insulating column prevents safety hazards by withstanding carbonized dust and impurities, protecting the high-voltage connection wire and improving safety by preventing ignition, thus ensuring the device's operational safety over extended use.
Implementation Method 1
the ion filament is input with high voltage through a high-voltage connection wire, and inducts with the discharge net to produce an electric field
Implementation Method 2
the material body of the ceramic insulating column has the feature of high temperature resistance and is not affected by the carbonized dust and impurity
Implementation Method 3
the dust and impurity are deposited on the ceramic insulating column. After long time use, the dust and impurity deposited on the surface of the ceramic insulating column are carbonized due to electric shock caused by the high voltage
