Solution Overview
Problem
The existing electrification apparatus for electric dust collectors is prone to damage due to excessive force during coupling, leading to reduced rigidity and efficiency, with the discharge tip often escaping, resulting in decreased electrification and discharge efficiency.
Innovation Solution

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, with the conductive microfiber and cable inserted through the lower frame and secured by the upper frame. This segmentation allows the coupling process to be simplified while distributing the mechanical stress across two frames, preventing damage to a single frame structure.
Solution Approach 2:
The conductive microfiber and cable act as intermediaries between the upper and lower frames. By inserting these components through the lower frame and securing them with the upper frame, the system achieves easy coupling while the distributed structure prevents excessive force from damaging a single frame.
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 installation frame is segmented into upper and lower frames, with the opening located only on the lower frame. This allows the coupling operation to be performed easily through the opening while the upper frame remains intact and provides structural support, maintaining overall rigidity.
Solution Approach 2:
The opening is localized to only one lateral surface of the lower frame, rather than opening the entire frame structure. This local quality approach allows easy coupling access while preserving the rigidity of the rest of the frame structure, particularly the upper frame which remains closed and structurally sound.
3Reliability
If the discharge tip is fixed at a position spaced apart from both fixed ends of the installation frame, then the electrical connection is achieved, 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 is merged with the cable assembly that passes through both the lower and upper frames. By combining the discharge tip positioning with the dual-frame structural support, the system achieves reliable electrical connection while the upper frame prevents the discharge tip from escaping due to vibration or external force.
Solution Approach 2:
The upper frame is designed to cover and secure the cable and discharge tip assembly beforehand, providing protective support against vibration and external forces. This prior cushioning structure prevents the discharge tip from escaping its predetermined position while maintaining reliable electrical connection.

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 disposed around the discharge tip and 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, and an upper frame that is coupled to the lower frame and that covers the conductive plate and the high voltage tip so that the discharge tip is exposed to outward.
