Integrated Cover Assembly for Image Forming Unit Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming systems require workers to manually detach and attach multiple cover members when mounting and removing external units, leading to increased time and complexity in the process.
Innovation Solution
An image forming apparatus and system design that incorporates a single cover member with integrated cover portions for both the connector and window openings, allowing for simultaneous exposure and protection of electrical connections, and a projection mechanism to prevent dust ingress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple cover members (connector cover and window cover) are disposed separately, then each opening can be covered independently, but the mounting and removing process becomes time-consuming and complex
Solution Approach 1:
The patent combines the connector cover and window cover into a single integrated cover member that simultaneously covers both the first opening (exposing the connector) and the second opening (exposing the component). This merging eliminates the need to separately attach and detach multiple covers, thereby reducing mounting and removing time while maintaining protection of both the connector and component.
Solution Approach 2:
The single cover member serves multiple functions: it acts as both the connector cover and the window cover, providing unified protection for both openings. The cover member is designed with a first cover portion for the first opening and a second cover portion for the second opening, enabling one component to perform the protective function that previously required two separate components.
2Reliability
If multiple cover members are disposed separately, then each can be optimized for its specific opening, but the overall device complexity increases
Solution Approach 1:
The patent merges two separate cover members into one integrated cover member that covers both openings. This reduces the number of components from two to one, simplifying the device structure while maintaining comprehensive protection. The integrated design includes a first cover portion and a second cover portion that work together as a unified protective element.
3Ease of operation
If the connector is exposed through an opening, then electrical connection is enabled, but the connector is vulnerable to dust and contaminants
Solution Approach 1:
The cover member is designed to cover the first opening when not in use, proactively protecting the connector from dust and contaminants before any harmful exposure occurs. The cover member can be easily removed or opened when electrical connection is needed, providing preliminary protection during non-operational states while maintaining accessibility during operational states.

AI summary
An image forming apparatus includes a casing, a connector, and a cover member. The casing including a first and second outer wall portions. The connector is provided inside of the casing and electrically connectable with the external unit. The cover member is attachable to and detachable from the casing. The first outer wall portion includes a first opening configured to expose a connection terminal of the connector. The second outer wall portion includes a second opening configured to expose a component provided inside of the casing. The cover member includes a first cover portion covering the first opening in a state where the cover member is attached to the casing, and a second cover portion formed integrally with the first cover portion and configured to cover the second opening when the cover member is attached to the casing.
