Vertical Color Printer Cover Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional color laser printers face issues with maintaining the external appearance of their exterior covers over time due to dirt and scratches, and they often have a large footprint due to the horizontal arrangement of image-forming units, which increases space requirements.
Innovation Solution
A color laser printer design with vertically arranged image-forming units, a paper supply unit above, and a discharge unit above the image-forming units, using ornamental members made of wood, fibers, or foam materials to cover the casing, allowing for easy replacement and maintenance, and a compact footprint by optimizing the placement of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If an exterior cover is made from synthetic resin, then the device can be manufactured cost-effectively, but the appearance deteriorates quickly due to dirt and scratches
Solution Approach 1:
The exterior cover is divided into a front cover and a rear cover that can be detached and replaced independently. The front cover, which is visible to users, can be easily swapped to maintain appearance, while the rear cover houses functional components. This segmentation allows the aesthetic portion to be replaced without affecting the functional portion.
Solution Approach 2:
The cover design incorporates detachable and replaceable components, transforming the static cover into a dynamic system where parts can be removed and reattached. This allows users to replace the front cover when it becomes dirty or scratched, extending the overall lifespan and appearance quality of the device.
2Productivity
If four image-forming units are arranged horizontally, then each color can be formed sequentially, but the device requires a much larger footprint
Solution Approach 1:
The patent transitions from a horizontal arrangement of image-forming units to a vertical arrangement. The four image-forming units (for yellow, magenta, cyan, and black) are stacked vertically along the paper conveyance path, utilizing the vertical dimension rather than expanding horizontally. This dimensional change maintains the full-color image formation capability while significantly reducing the device's footprint.
3Adaptability or versatility
If the exterior cover is flipped laterally to use both surfaces, then the cover can be reused, but it still becomes dirty and scratched easily
Solution Approach 1:
Instead of relying on flipping a single-cover design, the patent segments the cover into detachable front and rear covers. The front cover is designed specifically for aesthetic purposes and can be easily replaced when needed, while the rear cover serves functional purposes. This segmentation provides a more effective solution than flipping by allowing direct replacement of the visible surface.

AI summary
An image-forming device includes: a casing; an image-forming section including a plurality of image-forming units; a paper supply unit; and a discharge unit. The plurality of image-forming units are arranged substantially vertically within the casing when the casing is disposed in an orientation in which it is intended to be used, each image-forming unit forming an image in a corresponding color. The paper supply unit is disposed above the image-forming units when the casing is disposed in the orientation in which it is intended to be used. The paper supply unit is configured to accommodate a recording medium substantially in a vertical orientation and to supply the recording medium to the image-forming section. The discharge unit is disposed above the image-forming units when the casing is disposed in the orientation in which it is intended to be used. The discharge unit is configured to receive the recording medium discharged from the image-forming section substantially in a vertical orientation.
