Processing Unit Connector Alignment for Image Forming Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image forming apparatuses face difficulties in visually inspecting and properly connecting processing units due to the positioning of connectors, leading to potential electrical connection failures.
Innovation Solution
The image forming apparatus incorporates a first connector on the processing unit and a second connector on the main unit, with a groove portion and positioning portion that restricts movement in specific directions, ensuring easy and secure electrical connection through a drawer connector system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the connector is positioned on the back side of the apparatus main body for electrical connection, then the processing unit can be attached by insertion, but the connector positions become difficult to visually inspect, leading to improper connection
Solution Approach 1:
A guide rail structure serves as an intermediary between the processing unit and apparatus main body, providing visual guidance and physical alignment assistance during the attachment process, making the connector positions easily observable and alignable
Solution Approach 2:
The guide rail extends in the width direction (perpendicular to the insertion direction), adding a lateral dimension to the attachment process that enables visual inspection and manual alignment without requiring direct observation of the hidden connector positions on the back side
2Adaptability or versatility
If the processing unit is inserted from front to back for attachment, then the connection can be made, but the connector fitting becomes difficult due to invisible positions
Solution Approach 1:
The guide rail acts as a mediating structure that facilitates connector fitting by providing external visual and tactile guidance, allowing operators to align connectors without directly seeing their positions
Solution Approach 2:
The guide rail pre-aligns the processing unit with the apparatus main body before the connectors engage, performing the alignment action in advance to simplify the subsequent connector fitting process
3Device complexity
If no positioning structure is provided, then the attachment is simple, but the electrical connection may not be properly performed
Solution Approach 1:
The guide rail structure serves as a simple intermediary that provides both visual guidance and physical alignment, ensuring reliable connector engagement without adding complex positioning mechanisms
Solution Approach 2:
The guide rail replaces complex mechanical positioning systems with a simple guiding structure that uses external visual and tactile feedback instead of intricate internal alignment mechanisms

AI summary
Disclosed is an image forming apparatus including a main unit and a processing unit installed on an installation surface and configured to process the sheet discharged from a discharge portion. The processing unit includes a first connector electrically connected to the main unit; and a first positioning portion that protrudes from a bottom surface toward the installation surface. The main unit includes a second connector disposed, in a second direction, on a first side with respect to a sheet discharging position onto which the sheet is discharged from the discharge portion, the second direction crossing the first direction, and the second connector being electrically connected to the processing unit in a manner that the first connector is inserted into the second connector along the second direction; and a groove portion provided on the installation surface and engages with the first positioning portion.
