Cartridge Positioning Adapter for Stable Contact Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The unstable electrical connection between the first and second conductive contacts in an image forming apparatus due to the rotational force applied by the driving head, causing relative movement and affecting normal operation.
Innovation Solution
A positioning adapter with a first positioning part that cooperates with a matching part on the image forming apparatus to stabilize the transmission-connection between the first meshing part and the driving head, ensuring the maximum width of the positioning part's outermost contour exceeds the maximum line distance between conductive contacts, thereby reducing relative movement and enhancing contact stability.

If the driving head provides rotational force to the toner cartridge, then the toner transportation apparatus can be rotated for printing operation, but the toner cartridge swings and causes relative movement between conductive contacts, resulting in unstable electrical connection
Solution Approach 1:
A positioning adapter is introduced as an intermediary component between the toner cartridge and the main body. The adapter includes a positioning part that fits into a positioning matching part on the main body, serving as a mediator to stabilize the toner cartridge during rotation and prevent swinging that would otherwise cause unstable electrical connections between conductive contacts
Solution Approach 2:
The positioning adapter is installed in advance on the toner cartridge before insertion into the main body. This preliminary action of adding the positioning part prevents the harmful swinging motion before it can occur during the driving head's rotation, thereby preemptively ensuring stable electrical connection between conductive contacts

AI summary
A positioning adapter is installed on a cartridge that is detachably disposed on a main body of an image forming apparatus. The main body includes a first driving head, a first conductive contact, and a first positioning matching part. The cartridge includes a storage apparatus, with a second conductive contact, and a first meshing part. When the cartridge with the positioning adapter is inserted and installed into the main body, a first positioning part is configured to cooperate with the first positioning matching part to position the first meshing part, stabilizing a transmission-connection between the first meshing part and the first driving head. A maximum width of an outermost contour of the first positioning part is greater than or equal to a maximum line distance between any two of multiple contacts where the first conductive contact contacts the second conductive contact on the transverse cross-section of the main body.
