Toner Cartridge Force Receiving Part Leakage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing toner cartridges often experience poor engagement or disengagement of the rotational driving force transmission part with the force receiving part, leading to potential developer leakage during transportation and movement, causing environmental pollution.
Innovation Solution
A force receiving part is designed with a moving element, receiving element, transmission element, and elastic elements that securely engage with the rotational driving force transmission part of the image forming device, preventing developer leakage by ensuring proper alignment and sealing during installation and operation, and facilitating easy uninstallation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the rotational driving force transmission part is designed to easily engage and disengage with the force receiving part, then the ease of operation is improved, but the reliability of preventing developer leakage deteriorates
Solution Approach 1:
The force receiving part is divided into multiple functional components: a receiving element with receiving teeth for engagement, a moving element for force transmission, and a sealing element for leakage prevention. This segmentation allows each component to be optimized for its specific function while working together to solve the contradiction between easy operation and reliable sealing.
Solution Approach 2:
A sealing element is introduced as an intermediary component between the rotational driving force transmission part and the force receiving part. This sealing element fills the gap between the two parts, preventing developer leakage while allowing the mechanical engagement to remain smooth and easy for installation and uninstallation operations.
2Reliability
If the rotational driving force transmission part is deeply engaged with the force receiving part, then the reliability of force transmission is improved, but the ease of operation deteriorates due to difficulty in uninstallation
Solution Approach 1:
The receiving teeth are designed with dynamic engagement characteristics - they provide strong engagement during normal operation to ensure reliable force transmission, but allow smooth disengagement when needed. The moving element can shift positions to maintain optimal engagement during operation while enabling easy removal when required.
Solution Approach 2:
The sealing element is preliminarily positioned to engage with the rotational driving force transmission part before full engagement occurs. This preliminary sealing action prevents developer leakage from the outset while the mechanical engagement is established, allowing reliable force transmission without requiring excessive engagement depth that would make uninstallation difficult.
3Ease of manufacture
If the structure of the force receiving part is simplified, then the ease of manufacture is improved, but the reliability of preventing disengagement deteriorates
Solution Approach 1:
Multiple functions are merged into integrated components: the receiving element combines engagement (receiving teeth) and sealing functions; the moving element integrates force transmission and positioning. This merging reduces the total number of separate parts, simplifying manufacturing while maintaining reliable engagement through the combined action of the integrated components.
Solution Approach 2:
Different parts of the force receiving part have specialized local qualities: the receiving teeth are designed with specific geometry and material properties for strong engagement, while the sealing element has properties optimized for preventing leakage. This localized optimization allows each component to be manufactured efficiently for its specific function while collectively providing reliable engagement stability.

AI summary
A force receiving part and a toner cartridge are provided in the present disclosure. The toner cartridge includes a toner cartridge body and the force receiving part. The force receiving part is configured to receive a force from the image forming device and transmit the force to the toner cartridge body. The force receiving part includes a moving element, a receiving element for receiving the force, and a transmission element for transmitting the force. After the toner cartridge is installed on the image forming device, the force receiving part provided in the present disclosure enables automatic generation of an outlet for flowing out the toner when in use and for preventing the toner from flowing out by closing the outlet when not in use, which prevents the contamination and damage due to the developer leakage in the toner cartridge.
