Ribbon Cassette Triangular Clamping for Stable Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ribbon cassettes face issues with improper arrangement of guiding, positioning, and clamping structures, leading to tilting, difficulty in disassembly, and imbalanced assembly and pulling forces, which affect print quality and increase the overall volume of the cassette.
Innovation Solution
A ribbon cassette design with a cassette housing featuring a print head clamping groove, side wall, and position hole, along with clamping accommodation parts and position columns forming a triangular structure for stable assembly, and an installation method that uses elastic clamping to ensure proper alignment and reduce overall volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If guiding, positioning, and clamping structures are disposed on the outer peripheral surface of the ribbon cassette, then the ribbon cassette can be assembled, but the overall volume of the ribbon cassette increases
Solution Approach 1:
The patent applies the nesting principle by placing the guiding, positioning, and clamping structures inside the ribbon cassette housing rather than on the outer peripheral surface. The guiding holes, position holes, and clamping parts are integrated into the internal structure of the cassette housing, allowing these functional elements to be nested within the existing volume rather than adding to it from the outside.
2Ease of manufacture
If clamping parts and position holes are not configured with a good balance, then assembly is simple, but assembly force and pulling force are not balanced causing the ribbon cassette to tilt
Solution Approach 1:
The patent applies asymmetry by creating a balanced configuration where the guiding holes, position holes, and clamping parts are arranged in a specific asymmetric pattern that achieves force balance. The position holes are located at specific positions relative to the clamping parts, creating an asymmetric arrangement that distributes assembly force and pulling force evenly, preventing tilting while maintaining ease of assembly.
3Reliability
If guiding and positioning structures are disposed on the outer peripheral surface, then the ribbon cassette can be positioned, but the appearance smoothness of the ribbon cassette is affected
Solution Approach 1:
The patent applies nesting by moving the guiding and positioning structures from the outer peripheral surface to the internal structure of the cassette housing. The guiding holes and position holes are integrated into the housing walls, allowing the outer surface to remain smooth and aesthetically pleasing while the positioning functions are maintained through the nested internal arrangement.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures stable and accurate assembly of the ribbon cassette, improves print quality, reduces the overall volume, and enhances the appearance of the cassette while maintaining compatibility and ease of production.
Implementation Method 1
The first clamping part bends into the print head clamping groove to form a clamping inlet with the second clamping part

AI summary
The present disclosure provides a ribbon cassette, label printer, and installation method thereof. The ribbon cassette includes a cassette housing. A print head clamping groove, a side wall, and a position hole located inside the side wall are disposed on the cassette housing. A ribbon cutting part is formed at a connection between the side wall and the print head clamping groove. A first clamping accommodation part, a second clamping accommodation part, and a third clamping accommodation part are disposed on a surface of the cassette housing. The first clamping accommodation part, the second clamping accommodation part, and the third clamping accommodation part are respectively matched with a first position column, a second position column, and a third position column of a label printer.
