Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recording devices struggle with cutting thin or soft fabrics due to insufficient adhesion and permeability of ultraviolet curable ink, leading to issues like fraying, distortion, and performance degradation of the recording head.
Innovation Solution
A recording device equipped with an ink head for ejecting pigment ink and a curing process head for ejecting a curing process liquid that permeates the fabric, allowing for curing from the surface to the inside of the fabric, thereby enhancing cutting strength and reducing distortions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If ultraviolet curable ink is ejected to the cut position on fabric, then the ink adheres to the surface of the fabric, but cutting strength is insufficient and cutting becomes difficult or impossible when the cutting position is cut by a cutter or the like
Solution Approach 1:
The patent applies a porous processing liquid that penetrates into the fabric fibers rather than just adhering to the surface. This porous material infiltration allows the liquid to reach and strengthen the internal fiber structure, providing adequate cutting strength for thin and soft fabrics while enabling clean cutting without fraying.
Solution Approach 2:
The patent changes the physical and chemical parameters of the processing liquid from conventional ultraviolet curable ink to a specifically formulated porous processing liquid with different penetration characteristics. This parameter change enables the liquid to infiltrate fabric pores and provide internal reinforcement, resolving the contradiction between surface adhesion and cutting strength.
2Reliability
If ultraviolet curable ink is used for recording on thin fabric or soft fabric, then the ink adheres only to the surface of the fabric, but fraying occurs from a cut surface and fluff is generated
Solution Approach 1:
The porous processing liquid penetrates deep into the fabric fiber structure, creating internal bonding that prevents fiber separation. This internal reinforcement through porous material infiltration effectively suppresses fraying at cut surfaces and prevents fluff generation, maintaining fabric integrity throughout the processing.
Solution Approach 2:
The processing liquid is applied in advance to the fabric before cutting or sewing operations. This preliminary action allows the liquid to penetrate and strengthen the fabric structure proactively, preventing fraying and fluff generation before they can occur during subsequent processing steps.
3Productivity
If a localized pulling force is applied to fabric material during transport for printing, then distortion or wrinkles occur in the fabric material, but there is no description to consider these problems
Solution Approach 1:
The processing liquid is applied to the fabric in advance during the printing process, creating preliminary reinforcement in key areas. This preliminary action strengthens the fabric structure before subsequent handling and processing, enabling the fabric to resist distortion and wrinkles when subjected to localized pulling forces during transport and later operations.
Solution Approach 2:
The system applies processing liquid to specific local areas of the fabric rather than uniformly across the entire surface. This local quality approach provides targeted reinforcement at critical locations where pulling forces are most likely to cause distortion, while maintaining printing efficiency by avoiding unnecessary processing of the entire fabric area.
4Ease of operation
If thin fabric or soft fabric is fed through a sewing machine, then the fabric may twist or the sewing machine needle may push the fabric material rather than penetrate it, causing sewing defects
Solution Approach 1:
The processing liquid is applied to the fabric in advance before sewing operations. This preliminary reinforcement strengthens thin and soft fabrics, enabling them to withstand the mechanical stresses of sewing machine operation without twisting or preventing needle penetration, thereby ensuring high sewing quality.
Solution Approach 2:
The porous processing liquid penetrates into the fabric fiber structure, creating internal reinforcement that provides the necessary strength and stability for sewing operations. This internal strengthening allows thin and soft fabrics to be fed smoothly through sewing machines without twisting or resisting needle penetration, resolving the sewing quality issues.
