Toner Cartridge Force Receiving Part Sealing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing toner cartridges suffer from poor sealing and locking issues with the image forming device, leading to developer leakage and environmental pollution, as well as errors in operation due to inadequate structural design and material quality.
Innovation Solution
A force receiving part with elastic elements that automatically opens the toner cartridge during installation and seals it during uninstallation, preventing developer leakage and improving the engagement between the toner cartridge and the image forming device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the toner cartridge uses a simple connecting structure without elastic elements, then the device complexity is reduced, but the sealing reliability deteriorates causing developer leakage
Solution Approach 1:
The elastic element automatically performs the sealing action without requiring manual intervention or additional actuation mechanisms. When the toner cartridge is installed, the elastic element expands to seal the outlet; when removed, it contracts to open the outlet, enabling the structure to serve itself through elastic deformation.
Solution Approach 2:
The elastic element changes its physical state (expanded/contracted) based on the installation status of the toner cartridge. This parameter change allows a single component to provide both sealing and opening functions, improving reliability while controlling complexity.
2Reliability
If the toner cartridge outlet remains open during uninstallation, then the ease of operation is improved, but the loss of substance increases due to developer leakage
Solution Approach 1:
The elastic element is pre-loaded in a compressed state during cartridge installation, which automatically triggers the sealing action before the cartridge is fully engaged with the image forming device. This preliminary sealing action prevents developer leakage during subsequent handling and transportation.
3Reliability
If the driving tooth structure is designed with deep engagement, then the force transmission reliability is improved, but the ease of operation deteriorates due to locking with the image forming device
Solution Approach 1:
The elastic element provides a dynamic sealing mechanism that adapts to the installation and removal states of the toner cartridge. During installation, the elastic element compresses to seal; during removal, it expands to open, allowing smooth operation without locking while maintaining reliable force transmission through the driving tooth structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents developer leakage, reduces operational errors, and enhances the tightness of the toner cartridge, thereby maintaining image forming quality and preventing environmental pollution.
Implementation Method 1
a force receiving part with an elastic element, wherein the elastic element automatically opens the toner cartridge when the toner cartridge is installed into the image forming device; and automatically seals the toner cartridge when the toner cartridge is uninstalled from the image forming device

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. A second elastic member is provided inside the force receiving part, and the second elastic member is connected to the connecting portion at one end and the driving head at the other end; when the force receiving part is at the first position, the second elastic member has a tendency to push the driving head away from the toner cartridge body. The force receiving part further includes a first elastic member and / or a third elastic member. 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.
