Detachable Paper Storage for Multi-Size Roll Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printers require complex operations and inconvenient paper roll replacements due to the need for different paper storage sizes and upper cover openings for varying paper roll diameters.
Innovation Solution
A paper storage system with a detachable design, featuring a storage body, roller, and a pivoted upper cover that allows easy installation and removal without requiring separate detachment of parts or opening the upper cover, facilitating the use of multiple paper roll sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a printer uses a fixed paper storage structure for different paper roll diameters, then it can accommodate multiple paper sizes, but it requires complex replacement operations and opening the upper cover
Solution Approach 1:
The paper storage is divided into a detachable paper roll storage unit and a fixed printer body. The paper roll storage can be independently removed and replaced without affecting the printer body or requiring opening of the upper cover, thus simplifying the replacement operation while maintaining adaptability to different paper roll diameters through different storage units
Solution Approach 2:
The detachable paper roll storage is designed with a universal interface that can accommodate paper rolls of different diameters. The storage structure includes adjustable components and a standardized mounting mechanism that works with various paper roll sizes, providing multi-functionality without requiring complex replacement procedures
2Stability of the object's composition
If the paper storage is fixedly connected to the printer body, then the structure is stable, but the paper roll replacement becomes inconvenient and time-consuming
Solution Approach 1:
The paper storage system is segmented into a detachable paper roll storage component and a stable printer body. The detachable component can be quickly removed and replaced without disturbing the stable structure of the printer body, thus reducing replacement time while maintaining overall structural stability during operation
Solution Approach 2:
Multiple paper roll storages can be prepared in advance with different paper rolls. When replacement is needed, a pre-prepared storage unit can be immediately installed without requiring disassembly or adjustment, significantly reducing replacement time while the stable printer body maintains operational consistency

AI summary
Disclosed are a paper storage and a printer. The paper storage comprises: a warehouse body (20) for accommodating a medium, a medium outlet (A), and a roller (5) arranged on the storage body (20), wherein the medium outlet (A) is configured to discharge the medium accommodated in the storage body (20) after the medium passes by the roller (5), and an opening (224) opposite to the roller (5) is also arranged on a wall of the storage body (20), to allow an external medium processing device to match with the roller (5) through the opening (224) to process the medium. To replace the paper storage in a printer adopting such paper storage, the need for respective detachment of various parts of the paper storage, and the need for opening of the upper cover of the printer to load the paper roll are eliminated, thereby avoiding the problems of complex operations of replacing the paper roll and inconvenience in use.
