Desktop Card Printer Dual-Side Indent Printing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing indent printing technologies are limited in their ability to efficiently print characters on both sides of documents, such as credit cards, and lack versatility in ribbon materials and patterns.
Innovation Solution
The development of an improved indent printing apparatus with first and second indenting mechanisms and ribbon cartridges that allow for simultaneous printing on both sides of a document, using removable cartridges with various color materials and smart RFID tags for ribbon management, and the capability to print without an indent print ribbon.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single indent printing mechanism is used, then the device complexity is reduced, but the productivity is limited because only one side of the document can be printed at a time
Solution Approach 1:
The patent combines two indenting mechanisms (first indenting mechanism for front surface and second indenting mechanism for back surface) into a single integrated apparatus that operates simultaneously. This merging allows both sides of the card to be indented during one pass through the device, effectively doubling the productivity without requiring separate printing operations for each side.
Solution Approach 2:
The patent transitions from single-sided to double-sided indent printing by adding the second indenting mechanism that operates on the opposite side of the document. This dimensional expansion from one surface to two surfaces enables simultaneous processing of both card faces, significantly improving throughput while maintaining a compact apparatus design.
2Ease of operation
If removable ribbon cartridges are used, then the ease of operation is improved for ribbon replacement, but the device complexity increases due to cartridge housing and reel mechanisms
Solution Approach 1:
The patent divides the ribbon supply system into a removable cartridge module that contains the ribbon reel and housing. This segmentation allows the ribbon cartridge to be easily removed and replaced without disassembling the entire indent printing apparatus. The operator can simply extract the depleted cartridge and insert a fresh one, significantly improving ease of operation and reducing maintenance downtime.
Solution Approach 2:
The removable cartridge design enables the operator to perform ribbon replacement independently without requiring technical assistance or complex procedures. The self-service nature of the cartridge system allows quick exchange of ribbon supplies, minimizing interruption to the printing operation and improving overall operational efficiency.
3Adaptability or versatility
If multiple color materials are provided in separate cartridges, then the adaptability is improved, but the loss of time increases due to frequent cartridge replacements
Solution Approach 1:
The patent merges multiple color material options into a single multi-color ribbon cartridge that can provide different colors (such as black, red, and other materials) within one integrated unit. This combination eliminates the need to replace cartridges when switching between colors, as the multi-color ribbon can be selected and used from the same cartridge, thereby maintaining adaptability while reducing the time loss associated with frequent replacements.
Data Source
AI summary
An indent printing apparatus that is capable of indent printing on both sides of a document. A desktop card printer that uses the indent printing apparatus, a method of personalizing a document in the printer, and a ribbon cartridge used with the indent printing apparatus are also disclosed. The indent printing apparatus has first and second indenting mechanisms and uses first and second indent printing ribbon cartridges to enable indent printing on both side surfaces of the document.
