Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printers struggle to produce printed matters of high design quality, particularly in transferring and pasting transfer films onto transferee objects effectively.
Innovation Solution
A printer design that includes a transferee object sending unit, a transfer film sending unit, a printing device, a holding unit, and a pasting unit, with synchronized operations to ensure precise alignment and pasting of transfer films onto transferee objects, followed by cutting to achieve uniform printed sheets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the transfer film is directly pasted onto the transferee object without a holding unit, then the device complexity is reduced, but the alignment precision and image quality deteriorate
Solution Approach 1:
A holding unit is introduced as an intermediary component between the transfer film and transferee object. This holding unit temporarily holds both the transfer film and transferee object in a fixed position during the printing process, enabling precise alignment of the transfer film's image surface with the transferee object before pasting occurs.
2Manufacturing precision
If the transfer film is not held in a fixed position during printing, then the device complexity is reduced, but the manufacturing precision of the printed image deteriorates
Solution Approach 1:
The holding unit performs a preliminary action by fixing the transfer film and transferee object in the correct relative position before the printing process begins. This preliminary positioning ensures that when the printing device operates, the transfer film is stable and precisely aligned, resulting in high-quality printed images.
3Productivity
If the transfer film is sent out only downstream, then the device complexity is reduced, but the productivity is limited due to inability to rewind
Solution Approach 1:
The transfer film sending unit is designed with dynamic capability, allowing it to send the transfer film downstream during printing operations and rewind it upstream during positioning and pasting operations. This bidirectional movement capability enables flexible process control and improves overall productivity.
4Manufacturing precision
If the transfer film is not cut after pasting, then the device complexity is reduced, but the manufacturing precision of the final product deteriorates
Solution Approach 1:
The transfer film is segmented into individual portions corresponding to the size and position requirements of each transferee object. After pasting, the transfer film is cut into separate sections, ensuring that each printed image is uniformly sized and properly delimited, thereby improving product manufacturing precision.
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 printer achieves high design quality by ensuring the transfer film's image is visible through a transparent supporting layer, enhancing the aesthetic appeal of the printed matter.
Implementation Method 1
a pasting unit situated downstream of the holding unit and configured to paste the transfer film onto the transferee object with the transferred image printed on the transfer film
