Toner Container Attachment Mechanism for Image Forming Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses face challenges in ensuring compatibility and efficient use of toner containers, leading to potential image quality degradation and attachment issues due to varying toner specifications across different environments and countries.
Innovation Solution
The image forming apparatus incorporates a dual attachment system with unique positioning and engaging mechanisms for toner and waste toner containers, utilizing compatible keys and protruding bosses to ensure selective attachment based on type, allowing only compatible containers to be attached, and using a common protruding boss for waste toner containers to facilitate easy attachment and prevent mismatched containers from being used.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple compatible keys are provided for different toner container types, then toner container compatibility is improved, but device complexity increases
Solution Approach 1:
The attachment portion is segmented into two distinct functional components: a positioning member (protruding boss) for mechanical alignment and a compatible key system for type verification. This segmentation allows each component to perform its specific function independently, resolving the contradiction by organizing complexity into manageable segments rather than a monolithic structure.
Solution Approach 2:
The positioning member acts as an intermediary between the toner container and the attachment portion, providing a standardized mechanical interface that works across all container types. This intermediary element handles the basic positioning function, allowing the compatible key system to focus solely on type verification, thereby reducing overall system complexity.
2Reliability
If a toner container is selectively attached to the toner supplying portion, then image quality is maintained, but attachment operation becomes more complex
Solution Approach 1:
The compatible key system is designed to prevent incorrect attachment before it can occur. The shape-matched keys and keyholes create a mechanical barrier that physically blocks mismatched containers from being attached, eliminating the need for complex verification procedures and maintaining ease of operation while ensuring image quality.
Solution Approach 2:
The system performs self-verification through its mechanical design. The positioning member and compatible key configuration automatically ensure proper container-type matching without requiring user intervention or external verification, maintaining both reliability and operational simplicity.
3Ease of operation
If a common positioning member is used for both toner and waste toner containers, then ease of operation is improved, but compatibility control is reduced
Solution Approach 1:
The attachment system is segmented into two functional layers: a universal positioning member for mechanical alignment and a type-specific compatible key system for compatibility control. This segmentation allows the positioning member to serve all containers universally while the compatible keys provide type-specific verification, resolving the contradiction between ease of operation and compatibility control.
Solution Approach 2:
The positioning member is designed as a universal component that performs the same alignment function for both toner containers and waste toner containers. This universal element simplifies operation by providing a consistent interface, while the additional compatible key system layers on top of it provide the necessary type-specific control without complicating the basic attachment mechanism.

AI summary
An image forming apparatus includes: a toner supplying portion including a first attachment portion; and a waste toner collecting portion including a second attachment portion. A toner container includes a positioning member and a compatible key. The first attachment portion includes a first engaging portion configured to position the toner container to a first attachment position. The second attachment portion includes a second engaging portion configured to position the toner container to a second attachment position. The first engaging portion and the positioning member are formed in a shape that allows the toner container of a type corresponding to the first attachment portion to be selectively attached to the first attachment portion. The second engaging portion is formed in a shape that allows the positioning member to be engaged with a toner container of any one of a plurality of types.
