Ribbon Cartridge Segmented Case for Tape Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ribbon cartridges for tape printing apparatuses face difficulties in mounting due to the challenge of managing the tape's width direction movement during the insertion process.
Innovation Solution
The ribbon cartridge design incorporates a cartridge case with a first and second case portion, where the second case portion includes a second A and second B portion, allowing for a tape inlet, outlet, and path, and the second A case portion can open and close a path from the inlet to the middle, facilitating tape insertion and preventing movement during mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the tape is inserted in advance into the tape path before mounting the ribbon cartridge, then the tape is ready for printing, but it becomes difficult to perform the mounting work due to tape movement in the width direction
Solution Approach 1:
The cartridge case is divided into multiple segments: a first case portion, a second case portion, a second A case portion, and a second B case portion. This segmentation allows the tape path to be structurally separated from the main cartridge body, enabling the tape to be inserted and fixed in place before mounting, while the removable second A case portion provides access for tape insertion without complicating the mounting process.
Solution Approach 2:
The tape is inserted into the tape path in advance before the ribbon cartridge is mounted on the tape printing apparatus. The second A case portion is designed to be removable to facilitate this preliminary tape insertion action, allowing the tape to be prepared and positioned before the final mounting operation occurs.
2Ease of operation
If the second A case portion is made removable to facilitate tape insertion, then tape insertion becomes easy, but the device structure becomes more complex
Solution Approach 1:
The cartridge case is divided into multiple segments: a first case portion, a second case portion, a second A case portion, and a second B case portion. This segmentation allows the tape path to be structurally separated from the main cartridge body, enabling the tape to be inserted and fixed in place before mounting, while the removable second A case portion provides access for tape insertion without complicating the mounting process.
Solution Approach 2:
The second A case portion serves multiple functions: it forms part of the cartridge case structure, provides access to the tape path for tape insertion, and can be removed to allow tape insertion. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity despite the added operational capability.
