Solution Overview
Problem
The existing electrification apparatus for electric dust collectors is prone to frame damage due to excessive force during coupling, leading to reduced electrification and discharge efficiency, and instability in the discharge tip, which affects particle collection efficiency.
Innovation Solution
The apparatus features a structure where the upper frame covers the lower frame, securely mounting the conductive plate and high voltage tip, with a tip holder supporting the discharge tip and a ground mesh to distribute ions, ensuring the discharge tip's stability and maintaining frame rigidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the conductive microfiber and cable are press-fitted into the installation frame through an installation opening, then the coupling process is simplified, but the installation frame is highly likely to be damaged due to excessive force
Solution Approach 1:
The installation frame is divided into an upper frame and a lower frame that are coupled together. The conductive microfiber and cable are inserted through an installation opening in the lower frame and fixed by the upper frame pressing down, distributing the coupling force across two frames rather than concentrating it on a single frame structure.
Solution Approach 2:
The upper frame acts as an intermediary component that mediates the coupling force. Instead of directly pressing the microfiber and cable into the lower frame, the upper frame provides a distributed pressing surface that reduces localized stress on the lower frame structure.
2Ease of operation
If one lateral surface of the installation frame is opened to form the installation opening, then the coupling process is easier, but the rigidity of the installation frame remarkably decreases
Solution Approach 1:
The frame structure is segmented into upper and lower frames, each maintaining structural integrity independently. The installation opening is formed only in the lower frame, which maintains sufficient rigidity due to its closed structure, while the upper frame provides the necessary pressing force without requiring an opening.
Solution Approach 2:
The coupling force is applied in a vertical direction (from upper frame to lower frame) rather than horizontally through the lateral surface. This dimensional change allows the installation opening to be formed without compromising the overall structural rigidity, as the frame's strength is maintained through its vertical load-bearing structure.
3Manufacturing precision
If the discharge tip is fixed at a position spaced a predetermined distance apart from both fixed ends, then the discharge distribution is improved, but the discharge tip is highly likely to escape from the predetermined position due to vibration or external force
Solution Approach 1:
The discharge tip, high voltage cable, and grounding cable are merged into a single integrated assembly (high voltage tip part). This assembly is pre-structured with the discharge tip positioned at the correct distance from the conductive plate, ensuring manufacturing precision. The entire assembly is then fixed as one unit to the frame, preventing displacement due to vibration or external forces.
Solution Approach 2:
The discharge tip position is predetermined and pre-fixed in the high voltage tip part assembly during manufacturing. The distance between the discharge tip and conductive plate is established in advance through the cable holder structure, eliminating the need for post-installation adjustment and preventing position drift during operation.
4Reliability
If the upper frame covers the lower frame to secure mounting, then the frame rigidity and reliability are improved, but the device complexity increases
Solution Approach 1:
The frame is segmented into upper and lower frames that can be manufactured independently using standard manufacturing processes. This segmentation allows each frame to be optimized for its specific function (lower frame for cable insertion, upper frame for pressing and structural support) while maintaining overall simplicity through modular assembly.
Solution Approach 2:
The upper frame serves multiple functions: it provides structural support, applies pressing force to secure the cables and microfiber, and maintains the rigid structure needed for stable operation. By combining these functions into a single component, the overall device complexity is reduced despite the two-frame structure.

AI summary
An electrification apparatus for dust collection includes an electrification module configured to generate ions that are emitted to air. The electrification module comprises: a high voltage tip comprising at least one discharge tip configured to emit the ions in a direction opposite to a flow direction of the air, a conductive plate that surrounds the discharge tip and that is configured to generate an electric potential difference with the discharge tip of the high voltage tip, a lower frame that mounts the conductive plate and the high voltage tip, an upper frame that is coupled to a first side of the lower frame and that covers the conductive plate and the high voltage tip, the discharge tip protruding outward through the upper frame, and a ground mesh coupled to a second side of the lower frame.
