Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors in image forming devices often fail to establish a reliable connection with cartridges, leading to print errors and defects in print quality due to inadequate contact and interference with cartridge alignment.
Innovation Solution
The connector design includes an electrical contact that rotates during initial insertion to scrape off oxidation or contamination layers, ensuring a reliable connection and allowing for necessary cartridge movement during the image formation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the connector is constructed to establish adequate contact with the cartridge, then the electrical connection reliability is improved, but the connector may interfere with the precise alignment of the cartridge
Solution Approach 1:
The electrical contact is designed to rotate dynamically during cartridge insertion, transitioning from a stationary contact to a rotating scraping action. This dynamic movement allows the contact to adapt to cartridge position variations while maintaining reliable electrical connection, resolving the contradiction between connection reliability and alignment precision.
Solution Approach 2:
The connector changes its operational parameter from a fixed contact position to a rotating motion with controlled arc. This parameter change enables the contact to scrape off oxidation layers and contaminants while accommodating slight misalignments, thereby improving electrical connection reliability without compromising cartridge alignment precision.
2Reliability
If the connector makes firm contact with the cartridge, then the electrical connection is improved, but the connector prevents necessary movement of the cartridge during image formation
Solution Approach 1:
The electrical contact incorporates a rotating mechanism that allows it to move dynamically during cartridge insertion and operation. This dynamic design enables the contact to maintain firm electrical connection while permitting the cartridge to move as needed during the image formation process, resolving the contradiction between connection reliability and cartridge adaptability.
Solution Approach 2:
The rotating electrical contact performs a preliminary scraping action during insertion to remove oxidation and contamination layers before the cartridge is fully inserted and locked into position. This preliminary cleaning action ensures reliable electrical connection without preventing subsequent cartridge movement during operation.
3Device complexity
If the connector uses a stationary contact design, then the device complexity is reduced, but the electrical connection reliability deteriorates due to oxidation and contamination
Solution Approach 1:
The electrical contact transitions from a stationary design to a rotating mechanism that scrapes the cartridge surface during insertion. This dynamic rotating action effectively removes oxidation and contamination layers, significantly improving electrical connection reliability. The added complexity is minimal and focused solely on the rotating contact mechanism.
Solution Approach 2:
The rotation mechanism converts the potentially harmful effect of friction and wear into a beneficial scraping action that removes oxidation and contaminants from the contact surface. This transforms what would normally be considered wear and tear into a cleaning function that enhances electrical connection reliability over time.

Function Achieved in This Case
This design enhances the reliability of electrical contact between the image forming device and the cartridge, improving print quality by ensuring consistent and stable power and data transfer while allowing for precise cartridge alignment and movement.
Implementation Method 1
The electrical contact may be adapted to stop rotating after the cartridge is inserted the first amount. As a result, the electrical connector may slide across the surface of the cartridge during additional insertion and scrape off an oxidation or contamination layer

AI summary
The present application includes embodiments of a connector in an image forming device that establishes an electrical connection with a cartridge. The connector may include an electrical contact that is able to rotate in a first direction when in contact with the cartridge during a first amount insertion of the cartridge into the image forming device. The electrical contact may be adapted to stop rotating after the cartridge is inserted the first amount. As a result, the electrical connector may slide across the surface of the cartridge during additional insertion.
