Toner Container Alignment Guide for Electrical Contact Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing toner containers for image forming devices face challenges in accurately positioning electrical contacts relative to the image forming device, which can lead to unreliable connections and communication failures.
Innovation Solution
The toner container incorporates an alignment guide with an upper guide and a side guide, positioned on the first end of the body, which contacts the electrical connector of the image forming device during insertion. This alignment guide ensures the electrical contact of the toner container is accurately positioned higher than the drive coupler, facilitating a reliable connection with the corresponding electrical contact in the image forming device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electrical contact is positioned on the first end of the body, then the connection reliability is improved, but the positioning accuracy deteriorates without alignment guide
Solution Approach 1:
The alignment guide performs preliminary positioning action before the electrical contact engages with the image forming device. The alignment guide contacts the electrical connector first during insertion, establishing correct alignment in advance, which then ensures accurate positioning of the electrical contact when it engages with the corresponding contact in the image forming device.
Solution Approach 2:
The alignment guide acts as an intermediary element between the toner container and the image forming device. It mediates the positioning relationship by providing a reference surface that guides the electrical connector into correct alignment, thereby enabling reliable electrical contact without requiring extremely tight manufacturing tolerances on the electrical contact itself.
2Reliability
If the electrical contact is positioned higher than the drive coupler, then the connection reliability is improved, but the device complexity increases due to alignment guide requirements
Solution Approach 1:
The alignment guide is merged with the end cap structure of the toner container. Instead of being a separate complex assembly, the alignment guide is formed as an integral part of the end cap, combining the positioning function with the structural closure function. This reduces overall device complexity while maintaining the reliability benefit of positioned electrical contacts.
Solution Approach 2:
The end cap structure serves multiple functions: it closes the toner container body, provides mounting for the alignment guide, and facilitates the positioning of the electrical contact. By making the end cap multi-functional, the design avoids adding separate components, thereby reducing device complexity while achieving reliable electrical connection through the higher positioning of the electrical contact.
3Manufacturing precision
If the alignment guide contacts the electrical connector during insertion, then the positioning accuracy is improved, but the insertion force requirements increase
Solution Approach 1:
The positioning function is segmented from the main insertion function. The alignment guide handles the positioning task separately by contacting the electrical connector first, while the main body of the toner container completes the insertion. This segmentation allows the alignment guide to provide precise positioning without requiring the entire toner container to be pushed with excessive force, as only the alignment guide portion needs to engage initially.

AI summary
A toner container according to one example embodiment includes an alignment guide for contacting an electrical connector of an image forming device during insertion of the toner container into the image forming device to move the electrical connector of the image forming device relative to the toner container during insertion of the toner container into the image forming device with the first end of the body leading in order to align the electrical connector of the image forming device with an electrical contact of the toner container.
