Developer Container Exhaust Port Merging Section
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When the internal pressure of a developer container is high, air containing developer particles is likely to be discharged outside, leading to unwanted developer loss if not properly managed.
Innovation Solution
Incorporating a merging section within the air flow path to the exhaust port, where airflows from different directions intersect, reducing the amount of developer particles in the air discharged, by causing collisions and turbulence that keep particles inside the container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If an exhaust port is provided in the developer container to release air, then the internal pressure is reduced, but developer particles are discharged outside the container
Solution Approach 1:
The exhaust port is divided into a first exhaust port and a second exhaust port positioned at different locations. The first exhaust port is equipped with a developer removal unit that uses a magnetic field to remove magnetic carrier particles, while the second exhaust port allows direct exhaust. This segmentation allows selective removal of different types of particles at different locations, resolving the contradiction between pressure release and developer discharge prevention.
Solution Approach 2:
A developer removal unit acting as an intermediary is installed at the first exhaust port. This unit uses a magnetic field to selectively remove magnetic carrier particles from the exhaust airflow before they can be discharged outside the container. The intermediary mechanism allows the exhaust function to work while preventing harmful particle discharge.
2Productivity
If air flow path is made straight and direct to exhaust port, then exhaust efficiency is improved, but developer particles are more likely to reach exhaust port
Solution Approach 1:
The exhaust function is segmented into two separate exhaust ports: one dedicated to efficient air exhaust and another equipped with particle removal capability. This segmentation allows the system to achieve both high exhaust efficiency and effective particle containment by distributing different functions to different locations.
Solution Approach 2:
Different qualities are applied at different locations: the first exhaust port has a magnetic field-based developer removal unit for particle filtration, while the second exhaust port provides unobstructed airflow for efficient exhaust. This local differentiation allows each port to optimize its specific function while collectively solving the overall problem.
