Dual-Compartment Toner Bottle for Waste Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional xerographic printing devices require separate containers for fresh and waste toner, leading to printer downtime and inefficient waste management, as the waste toner receptacle often needs to be manually emptied and disposed of rather than recycled.
Innovation Solution
A replaceable toner bottle with dual compartments for fresh and waste toner, where the waste toner is collected and returned to the same bottle, eliminating the need for a separate waste toner container and integrating a feed mechanism to manage toner distribution and recycling within the printing device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate containers are used for fresh and waste toner, then waste toner can be collected, but printer downtime increases and device complexity increases
Solution Approach 1:
The patent combines the fresh toner container and waste toner receptacle into a single integrated toner bottle with separate compartments. The waste toner is returned to the same bottle from which fresh toner is supplied, eliminating the need for separate waste toner handling and reducing printer downtime.
Solution Approach 2:
The toner bottle serves multiple functions: it stores fresh toner, collects waste toner, and facilitates toner recycling. The single bottle design allows the system to handle both fresh and waste toner management in one component, improving operational continuity.
2Reliability
If separate waste toner receptacle is used, then waste toner can be collected, but device complexity increases
Solution Approach 1:
The patent merges the fresh toner container and waste toner receptacle into a single integrated toner bottle with separate compartments. This reduces the number of separate components from two (fresh toner container and waste receptacle) to one, simplifying the overall device structure.
Solution Approach 2:
The toner bottle serves multiple functions: it stores fresh toner, collects waste toner, and facilitates toner recycling. The single bottle design allows the system to handle both fresh and waste toner management in one component, reducing device complexity.
3Ease of operation
If waste toner is disposed of rather than recycled, then handling is simplified, but substance loss increases
Solution Approach 1:
The patent implements toner recovery by returning waste toner to the fresh toner compartment through a dedicated passage. This allows the system to recover and reuse toner particles that would otherwise be discarded, reducing substance loss while maintaining ease of operation through automated recycling.
Solution Approach 2:
The system automatically recycles waste toner by returning it to the fresh toner compartment without requiring manual intervention. The feed mechanism and passage system enable self-service toner recovery, reducing both substance loss and operational complexity.

AI summary
A toner bottle for use in a marking device with a feed mechanism. The toner bottle includes first and second compartments for holding fresh and waste toner, respectively. The feed mechanism allows fresh toner to be delivered to the marking engine from the bottle and waste toner to be returned to the bottle from the marking engine.
