Operation Unit Cable Length for Image Forming System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In image forming systems, the fixed positioning of operation units limits their size and mobility, leading to increased maintenance time and labor due to restricted movement, especially in large-scale systems, where service personnel must move excessively to diagnose and repair issues, and long arms to enhance mobility are costly and disruptive.
Innovation Solution
An image forming system with a separately movable operation unit connected to the apparatus body via a cable that can be adjusted in length, allowing the operation unit to be placed anywhere on the apparatus body without contacting the installation surface, enhancing mobility and reducing maintenance time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operation unit is disposed as a separate body supported by a long arm to enhance mobility, then the degree of freedom of movement is improved, but the cost increases and the long arm may disturb the maintenance operation
Solution Approach 1:
The operation unit is separated from the apparatus body and connected via a flexible cable, dividing the system into independent movable and stationary parts. This allows the operation unit to be positioned freely without requiring a long rigid arm structure.
Solution Approach 2:
The rigid arm mechanical connection is replaced with a flexible cable connection. The cable allows the operation unit to move freely while maintaining electrical connection, eliminating the need for complex long arm mechanisms.
2Ease of operation
If the operation unit is positioned remote from the failure location to allow free movement, then the mobility is improved, but the maintenance time increases due to excessive back-and-forth movement
Solution Approach 1:
The operation unit is made dynamically positionable rather than fixed, allowing it to be moved to the optimal position near the failure location during maintenance operations, reducing unnecessary movement time.
3Ease of operation
If the cable length is extended to allow the operation unit to reach distant positions, then the mobility is improved, but the operation unit may contact the installation surface causing damage
Solution Approach 1:
The cable length parameter is optimized to provide sufficient movement range while preventing the operation unit from reaching the installation surface. The cable acts as a physical constraint that limits excessive movement.

AI summary
An image forming apparatus has an apparatus body having an image forming portion capable of forming an image based on an image information, an operation unit disposed as a separate body from the apparatus body and operating the apparatus body, and a cable connecting the apparatus body and the operation unit and capable of conducting power. The cable has a length set so that the operation unit does not contact an installation surface on which the apparatus body is supported, according to which a freedom of placement of the operation unit is improved compared to a case where the operation unit is connected via an arm.
