Connector Mechanism for Detachable Option Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image forming apparatuses require complex and labor-intensive processes to connect and disconnect option devices, such as paper sheet feed cassettes, due to the need for manual lifting and replacement of connectors, which increases operational load and efficiency issues.
Innovation Solution
The implementation of a connector connection mechanism featuring a second connector that can be displaced between a connected and disconnected position, supported by a pivotable link portion and push portion, allowing for easy attachment and detachment of option devices without the need for manual lifting or tool-assisted disconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If connectors are made detachable without lifting the apparatus main body, then ease of operation is improved, but device complexity increases due to the link portion and coupling portions
Solution Approach 1:
The connector is nested within the holder, which is in turn nested within the option device. The link portion is disposed inside the holder, creating a compact nested structure that enables complex functionality while maintaining a small overall footprint and avoiding the need for external lifting mechanisms
Solution Approach 2:
The link portion acts as an intermediary mechanical element that transmits the pressing force from the push portion to the connector, enabling indirect actuation of the connector without requiring direct manual manipulation or external lifting of the apparatus main body
2Reliability
If the second connector is always connected to the first connector, then reliability is improved, but ease of operation deteriorates when disconnection is needed for maintenance
Solution Approach 1:
The system enables self-service maintenance by allowing the user to disconnect the connector through a simple pressing motion on the push portion, without requiring professional service or complex disassembly procedures. The coupling portions are designed to be releasable through user-operable pressing actions
Solution Approach 2:
The connector connection state is made dynamic rather than fixed. The connector can transition between connected and disconnected states through the pressing mechanism, allowing the system to adapt between reliable operation mode and maintenance mode as needed
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
Facilitates easy and efficient connection and disconnection of option devices, reducing operational load and improving maintenance efficiency by enabling secure coupling and decoupling without the need for screws or other fixing tools, even in a coupled state.
Implementation Method 1
The link portion is pivotably supported by the support frame, coupled with both the push portion and the second connector, and configured to, interlocking with the push portion being pressed, cause the second connector to be displaced from the second position to the first position

AI summary
An image forming apparatus includes an option device, the option device is coupled with a lower surface of an apparatus main body. A second connector is configured to be displaced between a first position and a second position. A push portion is configured to be pressed toward an inside of the option device when the option device is coupled with the lower surface. A link portion is pivotably supported, coupled with both the push portion and the second connector, and configured to, interlocking with the push portion being pressed, cause the second connector to be displaced from second position to first position. A first coupling portion couples the push portion with the link portion. A second coupling portion is configured to couple the second connector with the link portion. The first coupling portion and/or the second coupling portion is configured to release the coupling with the link portion.
