Solution Overview

Problem

Existing apparatus designs for image forming devices face challenges in efficiently dissipating heat and removing contaminants due to complex duct arrangements and large exterior configurations when multiple heat sources and scattering sources are present, leading to increased temperature and contamination issues.

Innovation Solution

A modular exterior structure using multiple panel elements with different functions, such as shielding, heat-radiating, and contaminant collecting panels, arranged in combination to cover the apparatus main body, allowing for efficient heat dissipation and contaminant removal without a complex duct system, with panel elements being easily replaceable and attachable to modify the layout as needed.

VSEngineering Contradiction Analysis

1Reliability

If ducts are arranged to connect each heat source and scattering source to exhaust ports, then heat dissipation and contaminant removal are achieved, but the apparatus becomes large and the exterior configuration becomes complicated

Engineering Contradiction:
Improveheat dissipation efficiencyVSAvoidexterior configuration complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The exterior is divided into multiple panel elements (first, second, third, and fourth panel elements) that can be independently arranged and configured. Each panel element can incorporate exhaust ports or ventilation holes at specific positions, allowing localized heat dissipation and contaminant removal without requiring complex centralized ductwork connecting all heat sources.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The panel elements serve multiple functions: they form the exterior structure, provide ventilation pathways, and can be configured with exhaust ports or ventilation holes depending on the local requirements for heat dissipation and contaminant removal. This multi-functionality eliminates the need for separate dedicated duct structures.

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

2Temperature

If multiple exhaust ports are distributed throughout the exterior, then heat dissipation efficiency is improved, but the exterior configuration becomes more complex

Engineering Contradiction:
Improveinternal temperature controlVSAvoidexterior structure complexity
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The exterior is segmented into multiple panel elements, each capable of incorporating exhaust ports or ventilation holes at appropriate positions. This segmentation allows heat dissipation to be distributed across multiple locations without requiring a complex integrated design, as each panel can be independently configured based on local thermal requirements.

Inventive Principle:
Principle #1Segmentation

AI summary

An exterior structure of an apparatus for covering the outside of an apparatus main body with a multiple number of panel elements uses shielding panels, heat-radiating panels and machine-interior anti-scatter panels as the multiple number of panel elements. The apparatus has a framework to which shielding panels, heat-radiating panels and machine-interior anti-scatter panels are appropriately arranged in combination to cover the apparatus in conformity with the functional configuration of the apparatus.
