Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional printer apparatuses face issues with cutting cloth labels made of materials like polyester, which are weak in stiffness and easily electrified, leading to potential jamming and sticking during the cutting process due to electrostatic charges.
Innovation Solution
A cutting device with a cutting section and conveyance unit that includes a paddle section attached to a rotation shaft, which scrapes out the cut cloth label to prevent sticking and includes a destaticizing brush to manage electrostatic charges, ensuring efficient conveyance and discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a cutting device is used to cut cloth labels, then the cloth label can be cut into predetermined length, but the cloth label becomes electrified due to friction during cutting causing sticking and jamming
Solution Approach 1:
The patent applies the principle of converting harm into benefit by using a destaticizing brush that generates electrostatic charge to counteract and neutralize the harmful electrostatic charge on the cloth label. The brush, made of conductive material or connected to a grounding source, transfers the accumulated static charge to ground, converting the harmful electrostatic attraction into a beneficial grounding action that prevents sticking and jamming during cutting operations.
2Productivity
If the cloth label is electrified during cutting, then cutting can proceed, but the electrified label sticks around the cutter causing jamming
Solution Approach 1:
The patent implements preliminary action by positioning the destaticizing brush in advance along the cutting path and activating it before the cloth label accumulates significant electrostatic charge. The brush continuously neutralizes static charge during the cutting process, preventing the label from sticking to the cutter in the first place rather than addressing sticking after it occurs.
3Device complexity
If a conventional cutting device is used without additional components, then the device structure remains simple, but the cloth label sticks and jams due to electrostatic charges
Solution Approach 1:
The patent applies multi-functionality by designing the destaticizing brush to serve multiple purposes: it acts as both a static neutralization device and a guide for the cloth label during cutting. The brush is integrated into the cutting mechanism, allowing it to perform both the function of neutralizing electrostatic charge and guiding the label through the cutting path, thereby adding functionality without proportionally increasing complexity.
