Cartridge Case Segmentation for Tape Roll Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tape cartridges face challenges in accommodating a ribbon roll and post-inserting a tape roll without separating the ribbon roll, as the ribbon roll is typically positioned between the cartridge main body and lid body, making it difficult to replace the tape roll without unraveling the ribbon roll.
Innovation Solution
A cartridge design featuring a third case portion that accommodates the ribbon roll, with a first case portion that opens and closes the tape roll accommodating portion, allowing for easy post-insertion of the tape roll without disturbing the ribbon roll, by separating the first and second case portions and using engagement projections and receiving portions for manual detachment and reattachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the ribbon roll is accommodated between the cartridge main body and lid body, then the cartridge structure is compact, but the ribbon roll separates when removing the lid body for post-inserting the tape roll
Solution Approach 1:
The cartridge case is divided into three separate case portions: first case portion (accommodating tape roll), second case portion (accommodating ribbon roll), and third case portion (common base). The first and second case portions are detachably connected to the third case portion, allowing independent access to the tape roll without disturbing the ribbon roll.
Solution Approach 2:
The first case portion is extracted as a separate detachable unit from the third case portion. This allows the tape roll accommodating portion to be opened by removing only the first case portion, while the second case portion containing the ribbon roll remains intact and connected to the third case portion.
2Ease of operation
If the first case portion and second case portion are integrated, then the cartridge structure is simpler, but the tape roll accommodating portion cannot be opened without disturbing the ribbon roll
Solution Approach 1:
The cartridge case is segmented into three distinct case portions with separate functions. The first case portion is dedicated to the tape roll and can be detached independently, while the second case portion is dedicated to the ribbon roll and remains connected to the third case portion. This segmentation enables selective access to the tape roll without affecting the ribbon roll.
Solution Approach 2:
The connection between the first case portion and third case portion is made detachable rather than fixed. This dynamic connection allows the first case portion to be removed and reattached as needed, providing flexibility for post-insertion operations while maintaining structural integrity when assembled.
