Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing image forming apparatuses face challenges in efficiently managing and visually inspecting toner bottles, particularly in ensuring easy replacement and preventing damage during operation.

Innovation Solution

The image forming apparatus incorporates a housing with an insertion opening and a cover that has an opening, allowing the toner bottle to be visible even when the cover is closed. A projecting component, such as an operation lever, enters the cover's opening, enabling it to open at a desired angle without restricting the layout of components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the cover is made solid without openings to protect the toner bottle, then protection is improved, but visual inspection capability deteriorates

Engineering Contradiction:

Improveprotection of toner bottleVSAvoidvisual inspection of toner bottle

Core Design Contradiction:

ReliabilityVSDifficulty of detecting and measuring

Solution Approach 1:

The cover is segmented into solid portions and a transparent window portion, allowing different regions to serve different functions: protection and visual inspection simultaneously

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The transparent window portion allows visual detection of the toner bottle state through transparency, enabling inspection without opening the cover

Inventive Principle:

Principle #32Color changes

2Difficulty of detecting and measuring

If the cover is made transparent to enable visual inspection, then visual inspection capability is improved, but protection capability deteriorates

Engineering Contradiction:

Improvevisual inspection of toner bottleVSAvoidprotection of toner bottle

Core Design Contradiction:

Difficulty of detecting and measuringVSReliability

Solution Approach 1:

The cover is divided into solid protective portions and a localized transparent window portion, maintaining overall protection while enabling inspection

Inventive Principle:

Principle #1Segmentation

3Ease of operation

If projecting components are added to enable cover opening, then ease of operation is improved, but risk of damage to components increases

Engineering Contradiction:

Improveopening of coverVSAvoiddamage to projecting components

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The transparent window serves as an intermediary that allows visual guidance for operating the projecting component, enabling users to see component positions and avoid damage while maintaining ease of operation

Inventive Principle:

Principle #24Intermediary (Mediator)
