RFID Transport Device for Envelope Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deposit facilities face issues with determining if an envelope has been printed, as the print head can dry out and become contaminated, and the printing unit must be positioned close to the envelope, limiting flexibility and increasing mechanical complexity.
Innovation Solution
The integration of an RFID unit into the transport device eliminates these issues by allowing for flexible placement and reducing the risk of contamination, enabling the use of smart labels that can be rewritten and reused, and allowing for various types of collection media.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an inkjet printer is used to print identifiers on envelopes, then unique identification is achieved, but the printhead can dry out and become contaminated, reducing reliability
Solution Approach 1:
The patent replaces the mechanical inkjet printing system with an RFID identification system. Instead of physically contacting the envelope with a printhead that requires ink and maintenance, the system uses electromagnetic fields to write identification data to RFID tags embedded in or attached to envelopes, eliminating printhead drying and contamination issues entirely
Solution Approach 2:
The patent introduces RFID tags as an intermediary between the identification system and the envelope. The RFID tag serves as a medium that can be remotely written to and read without direct physical contact, eliminating the need for a printhead that must maintain precise mechanical contact with the envelope surface
2Manufacturing precision
If the printing unit is positioned close to the envelope for printing, then identification is achieved, but the device complexity increases due to sealing units and precise positioning requirements
Solution Approach 1:
The patent replaces the mechanical printing positioning system with an RFID system that uses electromagnetic fields for communication. The RFID reader can write to tags at a distance without requiring precise mechanical alignment or complex positioning mechanisms, significantly reducing device complexity
Solution Approach 2:
The patent extracts and removes the complex sealing unit and precise positioning mechanisms from the printing system. By transitioning to RFID technology, the system eliminates the need for enclosed printing chambers and complex mechanical positioning, simplifying the overall device architecture
3Object-affected harmful factors
If the printhead is enclosed in a sealing unit to prevent contamination, then device cleanliness is improved, but the device complexity and mechanical setup effort increase
Solution Approach 1:
The patent replaces the mechanical sealing unit with a contactless RFID system. Since the RFID reader communicates with tags through electromagnetic fields without physical contact, there is no risk of ink contamination spreading to other device components, eliminating the need for complex sealing units
Solution Approach 2:
The patent removes the sealing unit entirely from the system architecture. By using RFID technology that operates without direct contact between the writing mechanism and the envelope, the system eliminates the contamination risk that would require sealing, thereby removing the complex sealing unit and associated mechanical complexity
