Printer Cutting Device Resin-Coated Base for Scrap Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The cutting ability of existing cutting devices in printers is compromised due to dust and scrap adhering to the supporting base, and repetitive contact between the clearance-forming part and the supporting base leads to abrasion of the coating, reducing the cutting ability over time.
Innovation Solution
A cutting device with a supporting base having a resin-coating layer in one area and a harder surface in another area, where the cutter section with a protrusive part contacts the supporting base, maintains a consistent cutting ability by preventing scrap adherence and abrasion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the supporting base is coated with a less adhesive material to prevent scrap adherence, then the cutting ability is improved, but the coating is abraded by repetitive contacts between the clearance-forming part and the supporting base
Solution Approach 1:
The supporting base is divided into two areas with different surface properties: a first area with a less adhesive coating material that prevents scrap adherence, and a second area with a harder coating material that resists abrasion from the clearance-forming part. This local differentiation allows each area to fulfill its specific functional requirement without compromising the other.
2Manufacturing precision
If the clearance-forming part contacts the supporting base to maintain cutting clearance, then the cutting precision is improved, but the coating on the supporting base is abraded
Solution Approach 1:
The supporting base surface is differentiated into a first area with less adhesive coating for scrap prevention and a second area with harder coating that contacts the clearance-forming part. This local quality differentiation ensures that the contact area has abrasion-resistant properties, preventing coating loss while maintaining cutting clearance precision.
3Object-generated harmful factors
If the supporting base has uniform coating for scrap prevention, then scrap adherence is reduced, but the coating durability is compromised due to abrasion
Solution Approach 1:
Instead of uniform coating, the supporting base has spatially differentiated coating properties: the first area has less adhesive coating material that prevents scrap adherence, while the second area has harder coating material that provides abrasion resistance. This local quality approach simultaneously addresses both scrap prevention and coating durability requirements.

AI summary
A cutting device, having a supporting base, a cutter section, a protrusive part, is provided. The supporting base has a first area, in which a tape is placeable, and a second area on a surface thereof. The surface is formed of a resin coating layer in the first area alone between the first area and the second area. The cutter section has a blade and is movable to approach and separate from the surface. The protrusive part protrudes from the cutter section in a direction, toward which an edge of the blade points. When the cutter section approaches the surface of the supporting base, with the protrusive part contacting the surface of the supporting base in the second area, the blade cuts the tape located between the surface of the supporting base in the first area and the blade partly in a direction of thickness of the tape.
