Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Printers generate fine particles during the printing process, which are not effectively collected, leading to decreased collection performance and increased soiling of components, affecting the quality and efficiency of the printing process.
Innovation Solution
An electrostatic dust collection device with a charging device, filter, and fan is used to collect fine particles, and a cleaning device is employed to maintain the collection device's performance by removing soiling through vibration, shock, or ultrasonic waves, and adjusting the voltage control to maintain optimal current flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a collection device is operated continuously to collect fine particles, then the collection performance is improved, but the collection device becomes soiled and performance decreases over time
Solution Approach 1:
The patent applies mechanical vibration to the collection device to remove accumulated fine particles and prevent soiling. The vibration mechanism periodically agitates the collection surfaces, dislodging collected particles and maintaining collection efficiency without requiring device disassembly or manual cleaning.
Solution Approach 2:
The collection device performs self-cleaning through integrated vibration mechanisms that automatically remove accumulated particles. This self-service capability maintains collection performance without external intervention, resolving the contradiction between continuous operation and performance degradation from soiling.
2Device complexity
If the collection device structure is simplified, then the device complexity is reduced, but the collection efficiency decreases
Solution Approach 1:
The patent combines the collection device with integrated vibration mechanisms and voltage control systems into a unified structure. This merging allows the device to maintain enhanced collection efficiency through multiple functions (collection, vibration cleaning, and electrical control) while avoiding the complexity of separate standalone systems.
Solution Approach 2:
The collection device is designed with multi-functionality, serving both as a fine particle collection system and a self-cleaning mechanism through integrated vibration elements. This universal design maintains high collection efficiency while managing overall device complexity through functional integration.
3Productivity
If voltage control is increased to improve particle collection, then the collection rate is improved, but the current flow and energy consumption increase
Solution Approach 1:
The patent implements periodic voltage control where high voltage is applied intermittently rather than continuously. The voltage is increased during collection phases to maximize particle capture rate, then reduced during vibration cleaning phases, creating a periodic pattern that maintains high collection rates while managing energy consumption through cyclical operation.
Solution Approach 2:
The voltage control system dynamically adjusts voltage levels based on operational phase - higher voltage during active collection to improve capture rate, and reduced voltage during cleaning phases. This dynamic adjustment optimizes the balance between collection productivity and energy consumption rather than maintaining constant high voltage.
