MFP Ink Cartridge Replacement via Normal Path
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Multi-Function Peripherals (MFPs) face issues with wasted interior space, increased device size, and difficulty in ink cartridge replacement due to inefficient space design, where the scanning module overlaps with the inkjet printing module, obstructing access and accuracy during replacement.
Innovation Solution
The MFP design features a scanning module on top and an inkjet printing module below, with the ink cartridge moving path normal to the scan platform, allowing the cartridge to be replaced by moving it away from under the scan platform, thus providing a more accessible and convenient replacement process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the scanning module is located above the printing module with overlapping arrangement to reduce device size, then the device compactness is improved, but the interior space is wasted and the device size increases
Solution Approach 1:
The patent changes the spatial relationship between the scanning module and inkjet printing module from a vertical stacking arrangement to a horizontal side-by-side arrangement. The ink cartridge moving path is oriented substantially normal to the longitudinal axis of the scan platform, allowing the ink cartridge to move away from under the scan platform during replacement. This dimensional reorganization eliminates the need for excessive interior space while maintaining compact device footprint.
2Area of stationary object
If the scan platform is made large to cover the entire inkjet printing module moving path, then the scanning coverage is improved, but the ink cartridge replacement becomes difficult
Solution Approach 1:
The patent segments the functional areas by orienting the ink cartridge moving path substantially normal to the longitudinal axis of the scan platform. This creates distinct operational zones where the ink cartridge can be accessed and replaced at positions that do not interfere with the scan platform's scanning operations. The scan platform maintains sufficient area for scanning while the ink cartridge path is separated to enable easy replacement.
3Volume of stationary object
If the ink cartridge moving path is parallel to the scan platform longitudinal axis, then the space utilization is improved, but the user's vision is blocked during replacement operations
Solution Approach 1:
The patent introduces asymmetry in the spatial arrangement by orienting the ink cartridge moving path substantially normal to the longitudinal axis of the scan platform rather than parallel. This asymmetric configuration creates an ergonomic workspace where the user can access the ink cartridge replacement area with unobstructed vision, while still maintaining efficient space utilization within the device interior.

AI summary
A multi-function peripheral mainly includes a casing, a scanning module and an inkjet printing module. The scanning module is located on the top side of the casing, including a scan platform and a dynamic scanning unit for capturing image data. The inkjet printing module is located below the scan platform and includes a dynamic printing unit for moving an ink cartridge to perform printing operations. The moving path of the ink cartridge is substantially normal to the longitudinal axis of the scan platform. When the ink cartridge is moved to a cartridge replacing position located on a distal end of the dynamic printing unit, it escapes from under the scan platform to facilitate cartridge replacement operations.
