Solution Overview
Problem
Filter modules with high voltage and ground electrodes face electrical connection issues due to collected foreign substances, which can lead to reduced performance and efficiency in air filtration.
Innovation Solution
A filter module design incorporating a spacer to maintain a space between the filter surfaces and electrodes, preventing electrical connection even when a predetermined amount of foreign substances are collected, using a porous electrode structure and a housing with specific openings and rib portions to accommodate the electrodes and spacer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the filter collects foreign substances to improve filtration performance, then the filtration efficiency is improved, but the electrical connection between high voltage electrode and ground electrode may occur through the collected foreign substances
Solution Approach 1:
The patent introduces a spacer as an intermediary component positioned between the filter and the high voltage electrode. This spacer maintains a predetermined distance between the filter surface and the high voltage electrode, preventing direct electrical contact through collected foreign substances while allowing the filtration function to continue operating effectively.
Solution Approach 2:
The spacer is pre-installed in the filter module structure before operation begins, establishing a permanent physical barrier that prevents electrical connection issues from occurring in the first place, rather than addressing them after they arise.
2Productivity
If the distance between filter surface and electrode is reduced to improve electrostatic collection, then the foreign substance collection efficiency is improved, but the risk of electrical connection through foreign substances increases
Solution Approach 1:
The spacer serves as a mediator that allows the filter to be positioned close to the high voltage electrode for effective electrostatic collection, while simultaneously preventing direct contact between the filter and electrode, thus eliminating the harmful electrical connection risk.
Solution Approach 2:
The spacer provides localized electrical isolation at the critical interface between the filter and high voltage electrode, while allowing the rest of the filter structure to maintain its filtration function without interference.
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 spacer effectively isolates the electrodes, preventing electrical connection and maintaining filtration efficiency even with a large amount of collected foreign substances, ensuring continuous air purification performance.
Implementation Method 1
a spacer configured to maintain a space in at least one of between the first surface and the first electrode or between the second surface and the second electrode
Implementation Method 2
The first electrode and the second electrode may be each formed of a porous electrode including a conductive panel and a plurality of holes formed in the conductive panel
Implementation Method 3
when power is applied to the high voltage electrode and the ground electrode, an electrostatic force is generated in the filter by a potential difference between the high voltage electrode and the ground electrode. As foreign substances contained in the air passing through the filter are adsorbed to the filter by the electrostatic force
