Tape Supply Device Horizontal Roll Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tape cartridges for rendering tape printing machines are limited by the winding diameter of the tape roll, restricting the elongation of the tape and causing issues with tape tension and feeding during printing.
Innovation Solution
A tape supplying device that supports the tape roll in a posture where the rotation axis crosses the mounting surface, allowing for the installation of tape rolls with larger diameters without interfering with the printing device, and supplies the tape in a state where the device is not secured to the printing device, preventing tension fluctuations and sagging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the tape roll is placed on conventional tape cartridge supporting arms, then the tape printing device can be compact, but the winding diameter of the tape roll is restricted which limits tape elongation
Solution Approach 1:
The patent changes the spatial arrangement by supporting the tape roll horizontally with its rotation axis extending left-right rather than vertically. This dimensional change allows the tape roll to achieve larger winding diameters without increasing the vertical height of the printing device, thus resolving the contradiction between tape elongation and device compactness.
2Reliability
If the tape supplying device is installed on the tape printing device, then the structure is integrated, but tape tension and feeding become problematic
Solution Approach 1:
The patent divides the system into two independent parts: the tape printing device and the tape supplying device. The tape supplying device is positioned separately to the left and supports the tape roll independently, eliminating the need for complex installation structures while ensuring reliable tape feeding through proper tension control.
3Length of moving object
If the tape roll has large winding diameter, then tape elongation is improved, but the tape roll interferes with the mounting surface
Solution Approach 1:
The patent reorients the tape roll from a vertical arrangement (rotation axis perpendicular to mounting surface) to a horizontal arrangement (rotation axis parallel to mounting surface). This dimensional change allows large winding diameters without interference with the mounting surface, as the roll rotates in a plane parallel to rather than perpendicular to the mounting surface.
