Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrostatic fine dust filter systems for small fireplaces and hearths are difficult to install, maintain, and clean, as they require costly industrial solutions and pose safety risks for chimney sweeps due to rigid structures that obstruct cleaning processes.
Innovation Solution
A moveable and self-restoring holder for the high-voltage electrode with cambered flexible parts, allowing the electrode to be easily deflected during cleaning and automatically returning to its operating position, combined with a cambered spring steel electrode design for enhanced flexibility and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid electrode holder structure is used, then the electrode is stable and secure, but cleaning becomes difficult and dangerous due to obstruction
Solution Approach 1:
The electrode holder is designed with flexible, resilient arms that can dynamically change their position. During normal operation, the arms maintain the electrode in a stable, secure position. During cleaning, the arms can be manually deflected to move the electrode out of the way, allowing cleaning access, and then automatically return to their original position to restore electrode stability.
Solution Approach 2:
The holder uses resilient materials that can change their physical state between rigid (during operation) and flexible (during cleaning). The resilient arms can be deflected beyond their elastic limit temporarily during cleaning, then spring back to their original configuration, effectively changing the rigidity parameter of the holder structure as needed.
2Productivity
If industrial cleaning solutions are used, then cleaning effectiveness is improved, but cost becomes prohibitive for private use
Solution Approach 1:
The flexible holder structure enables the system to facilitate its own cleaning process by allowing manual access and movement of the electrode. The resilient arms can be easily deflected by hand to move the electrode out of the way, and then automatically return to position, effectively serving the cleaning function without requiring external industrial cleaning equipment or services.
3Ease of repair
If chimney cleaning is performed annually by sweeps, then maintenance is completed, but safety risks arise from rigid structures
Solution Approach 1:
The flexible, resilient holder allows the electrode to be safely moved out of the way during cleaning operations by simply deflecting the arms, eliminating the need for chimney sweeps to work around rigid, obstructive structures. This dynamic flexibility greatly reduces safety risks associated with working with rigid electrostatic components.

Function Achieved in This Case
Facilitates easy installation, maintenance, and cleaning of electrostatic fine dust filter systems from both the roof and below, ensuring safety and reducing the need for costly industrial solutions by allowing the electrode to be moved out of the way during cleaning and automatically returning to its operational position.
Implementation Method 1
The corona discharge takes place on a charged high-voltage electrode suitable for this purpose in the interior of the waste gas chimney. The electrode is designed having projecting tips and possibly sharp edges, since there the density of the field lines and thus also the electric field strength is greatest and therefore the corona discharge is promoted.
Implementation Method 2
dust particles are electrically charged by corona discharge and are attracted to the oppositely charged electrode
Implementation Method 3
the holder is equipped with at least one restoring element with a restoring property, which forms an articulated connection between the at least one installation means and the holding means and which allows the holding means and optionally a high-voltage electrode attached thereto to move out of the way from the operating position during cleaning in the waste gas duct with a cleaning device, and allows an automatic return to the operating position

AI summary
The invention relates to a retainer for an electrostatic high-voltage electrode, containing a high-voltage insulator, on the electrode side of the insulator at least one arm having a retaining means for retaining a high-voltage electrode hanging on the retaining means preferably vertically, and on the installation side of the insulator at least one installation means for installing the retainer at an installation point outside an exhaust gas channel of a chimney. Said retainer is characterized in that the retainer is equipped with at least one restoring element, which forms an articulated connection between the at least one installation means and the retaining means and which allows the retaining means and optionally a high-voltage electrode attached thereto to move out of the way from the operating position during cleaning in the exhaust gas channel with a cleaning device and allows an automatic return to the operating position.
