Universal Endplate Channel Modification for Toner Cartridge Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Printer cartridges, particularly toner cartridges and imaging drum units, are designed for specific printer models, limiting their compatibility and requiring modifications to function across different devices, which is inefficient in the recycling and refurbishment process.
Innovation Solution
Modifying the shape of channels on the endplates of toner cartridges to allow them to be installed and function in multiple printer models, including the use of universal endplates that can fit across various printer types by altering the size and shape of existing channels to remove physical restrictions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If toner cartridges are designed with specific physical characteristics (protrusions, channels) for particular printer models, then they ensure proper alignment and function in those models, but they limit compatibility with other printer models
Solution Approach 1:
The patent applies universality by designing endplates with standardized channel configurations that can interface with multiple printer models. The endplates are engineered to accommodate different printer types while maintaining proper toner delivery function, allowing a single cartridge design to serve multiple applications without compromising reliability
Solution Approach 2:
The patent utilizes parameter changes by systematically varying channel dimensions, positions, and geometries in the endplate design. By adjusting these physical parameters, the endplates can adapt to different printer model requirements while maintaining functional integrity, thus resolving the contradiction between compatibility and proper alignment
2Ease of operation
If protrusions and channels are added to distinguish different toner cartridge colors, then proper installation is ensured, but modifications are needed to enable use in different locations within the same printer
Solution Approach 1:
The patent applies segmentation by separating the color-identification protrusion features from the functional channel structures. This allows the channels to be optimized for proper installation in different printer locations while the protrusions serve as optional color-coding elements that do not interfere with the modular adaptability of the endplate design
Solution Approach 2:
The endplate serves as an intermediary component that mediates between the toner cartridge body and the printer interface. By concentrating the adaptation features (channels, protrusions) in this intermediate element, the design enables easy reconfiguration for different installation locations while maintaining proper installation guidance through controlled protrusion placement
3Adaptability or versatility
If the shape of channels on endplates is modified to enable multi-model compatibility, then versatility is improved, but manufacturing complexity increases
Solution Approach 1:
The patent reduces manufacturing complexity by designing endplates that serve multiple printer models simultaneously. Rather than creating unique endplates for each printer model, a universal endplate design with standardized channel patterns is developed, simplifying the manufacturing process while maintaining multi-model compatibility
Solution Approach 2:
The patent manages design complexity by systematically varying channel parameters (width, depth, position) based on printer model requirements. This parameter-based approach allows for controlled complexity where only necessary variations are implemented, avoiding unnecessary design complexity while achieving the required adaptability

AI summary
Methods are provided for modifying an imaging process cartridge intended for installation in one type of printer to be installed in at least one other type of printer. In one embodiment, a method of modifying the imaging process cartridge may include modifying one or more endplates of the imaging process cartridge. In another embodiment, one or more of the endplates is removed and replaced with a replacement endplate.
