Image Forming Casing Layout for Easier Wiring Unit Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses face increased labor requirements for mounting wiring due to the need to maneuver around struts and stays when assembling wiring units between the front and rear sides of the apparatus body.
Innovation Solution
The image forming apparatus is designed with separable casings that allow the wiring unit to be mounted onto a side of a frame, with openings covered by the other frame when connected, enabling vertical mounting and easy routing of wiring without maneuvering around internal structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If wiring units are assembled while maneuvering around struts and stays within the apparatus body, then wiring can be mounted from the front side to the rear side, but labor requirements increase and workability deteriorates
Solution Approach 1:
The apparatus body is divided into a first casing and a second casing that can be separated. The wiring unit is mounted on the second casing separately, and then the second casing is connected to the first casing. This segmentation allows wiring assembly to be performed on an open side without maneuvering around internal struts and stays, thereby improving workability and reducing assembly complexity.
2Ease of operation
If wiring is disposed from the front side to the rear side within the apparatus body, then electrical components on both sides can be connected, but the wiring assembly process becomes more difficult due to spatial constraints
Solution Approach 1:
Instead of assembling wiring within the constrained three-dimensional space of the closed apparatus body, the invention utilizes the external dimension by separating the casings. The wiring unit is assembled on the outside of the second casing before connection, transforming a difficult internal 3D assembly operation into a simpler external operation with better accessibility.

AI summary
An image forming apparatus configured to form an image on a recording material, the image forming apparatus includes a first casing including a first frame, a second casing including a second frame, the second casing being connected to the first casing and configured to be separable in a vertical direction from the first casing, and a wiring unit including wiring connected to an electrical component. The second frame includes a mounting portion to which the wiring unit is mounted. The mounting portion is provided with at least one opening on a side facing the first frame. The opening is at least partially covered by a part of the first frame in a state in which the first casing and the second casing are connected to each other.
