Carriage Positioning for Ink Cartridge Grip Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In on-carriage type inkjet recording devices, the close arrangement of ink cartridges makes it difficult for users to grip and replace individual cartridges effectively.
Innovation Solution
The design includes a carriage that moves between positions to expose grip parts of cartridges outside the casing through dedicated openings, allowing for easier access and replacement by offsetting the grip parts from the distal openings of the cartridges, facilitating user interaction during maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If multiple ink cartridges are arranged closely together on the carriage to save space, then the device can be more compact and space-efficient, but it becomes difficult for users to grip and replace individual cartridges
Solution Approach 1:
The patent applies dimensional change by moving the grip parts from the front-rear direction (where cartridges are closely arranged) to the lateral direction. The carriage is designed to move laterally between a first position and a second position, bringing different grip parts to opposite lateral sides of the device. This allows users to access grip parts from lateral openings rather than from the front-rear direction, effectively resolving the space vs. accessibility contradiction by operating in a different spatial dimension.
Solution Approach 2:
The patent implements dynamics by making the carriage movable between two positions. The carriage can dynamically switch between: (1) a first position where the first grip part is accessible through the first lateral opening, and (2) a second position where the second grip part is accessible through the second lateral opening. This dynamic repositioning allows the system to adapt to different cartridge replacement needs while maintaining compact cartridge arrangement.
2Area of stationary object
If cartridges are arranged in a compact configuration on the carriage, then space utilization is improved, but access to grip parts for user interaction is reduced
Solution Approach 1:
The patent resolves this contradiction by introducing lateral accessibility as a new dimension. Instead of arranging grip parts along the front-rear direction where space is limited, the system provides lateral openings on opposite sides of the casing. The carriage movement mechanism brings different grip parts to these lateral openings, allowing users to access cartridges from the sides rather than from the front-rear direction, thus improving accessibility without sacrificing compact arrangement.
Solution Approach 2:
The carriage acts as an intermediary mechanism between the compactly arranged cartridges and the user's hand. It mediates the contradiction by transporting the cartridges (or rather, their grip parts) to accessible positions at the lateral openings. The carriage's movement between first and second positions allows it to present different cartridges for replacement through different lateral openings, effectively bridging the gap between compact internal arrangement and external user accessibility.

AI summary
A liquid ejecting device includes a casing, a carriage, and a cartridge. The carriage is configured to move in a first direction and a second direction. The cartridge is configured to be removably mounted on the carriage and includes a first cartridge and a second cartridge. The first cartridge has a first grip part. The second cartridge has a second grip part. The carriage is configured to move between a first position where the first grip part is exposed and positioned outside the casing through a first opening and a second position where the second grip part is exposed and positioned outside the casing through a second opening.
