Solution Overview

Problem

Existing image forming apparatuses face challenges in managing cables, leading to complexity and potential noise interference due to cable layout around the apparatus body, which affects usability and reliability.

Innovation Solution

A cable holder with multiple holding portions and stoppers is integrated under the apparatus body, featuring outlets at different positions to manage cable layout and reduce noise interference, along with an extension cable system that allows cable connection from a rear face, eliminating the need for complex cable routing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If cable is laid around the apparatus body using existing spaces or grooves, then cable routing is achieved, but device complexity and noise interference increase

Engineering Contradiction:
Improvecable managementVSAvoidcable layout complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The cable holder is divided into multiple cable holding portions (first, second, third holding portions) with different orientations and functions. Each portion handles cables in specific directions, segmenting the complex cable management task into manageable sections that reduce overall system complexity while improving ease of operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention introduces a vertical dimension by extending cable holding portions in different directions (front-rear, left-right) and using a stopper that protrudes upward from the cable laying surface. This multi-dimensional approach organizes cables in three-dimensional space rather than simple two-dimensional routing, reducing complexity and interference.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If cable is routed around the apparatus body, then connection is achieved, but noise interference increases

Engineering Contradiction:
Improvesignal synchronizationVSAvoidnoise interference
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The cable holder and extension cable system extracts the cable routing function from the main apparatus body. By providing dedicated cable holding portions and an extension cable that extends outward, the patent separates high-frequency signal cables from potential noise sources within the apparatus, reducing electromagnetic interference and improving signal reliability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The extension cable acts as an intermediary element between the apparatus body and external connections. It provides a controlled pathway for cables to exit the apparatus, mediating between the internal environment (with potential noise) and external connections, thereby protecting signal integrity.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If multiple cables are managed using traditional methods, then cable connections are established, but usability decreases

Engineering Contradiction:
Improvecable connection flexibilityVSAvoidusability
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The cable holder is designed with multiple cable holding portions that can accommodate different cable types and routing directions. The stopper mechanism provides universal functionality by preventing cable disconnection regardless of cable type, while the multiple holding portions offer versatile cable routing options, thereby improving ease of operation without sacrificing adaptability.

Inventive Principle:
Principle #6Universality (Multi-functionality)
