Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional developer collection apparatuses face issues with toner accumulation in suction ducts leading to increased ventilation resistance and decreased toner collection rates due to clogging and inefficient suction mechanisms.
Innovation Solution
The developer collection apparatus incorporates a suction duct with an auxiliary fan that blows air through a middle point to prevent toner accumulation, combined with a vibration mechanism to clear clogs and a control unit to manage fan operations, enhancing suction efficiency and reducing ventilation resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a suction duct is used to collect scattered toner from the developing unit, then toner collection is achieved, but toner accumulates in the suction duct causing increased ventilation resistance and decreased collection rates
Solution Approach 1:
The auxiliary fan performs preliminary action by blowing air through the suction duct before toner accumulation becomes severe. This preventive measure clears toner from the duct regularly, maintaining low ventilation resistance and ensuring the suction system continues to operate at high collection rates without clogging
Solution Approach 2:
The invention uses pneumatic action by introducing a second fan that blows air through the suction duct. This pneumatic flow counteracts toner accumulation by continuously clearing the duct interior, thereby maintaining low ventilation resistance and preventing the degradation of suction performance
2Productivity
If the suction fan runs continuously to maintain collection efficiency, then toner collection rate is improved, but energy consumption increases
Solution Approach 1:
The auxiliary fan operates periodically rather than continuously, being activated at predetermined intervals to clear toner from the suction duct. This periodic operation maintains suction efficiency by preventing accumulation while significantly reducing energy consumption compared to continuous operation of either fan
Solution Approach 2:
The auxiliary fan provides self-service by automatically clearing toner accumulation in the suction duct during predetermined intervals. This self-maintenance function ensures the primary suction fan can continue operating efficiently without requiring continuous high-power operation or manual intervention
