Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing RFID label producing apparatuses face inefficiencies due to the risk of print defects when communication with RFID circuit elements fails during the production process, leading to potential thin spots or blank spaces on the label surface, which can lower the overall printing quality and process efficiency.
Innovation Solution
A tag label producing apparatus that includes a printing device, a transmitting/receiving device, a feeding device, a coordination control portion, a communication determining portion, and a decision portion to coordinate the operations of these components, allowing for controlled stopping and retrying of the feeding process when communication with RFID circuit elements fails, ensuring successful information transmission/reception without interrupting printing and minimizing print defects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If communication retry is performed by stopping feeding, then communication success rate is improved, but print defects occur on the label surface
Solution Approach 1:
The patent implements dynamic control of the feeding mechanism based on communication status. When communication fails, the system dynamically stops feeding to enable retry, then resumes feeding after successful communication. This dynamic adjustment resolves the contradiction by making the feeding process adaptive to communication requirements while maintaining printing quality through coordinated control of the printing and feeding operations.
Solution Approach 2:
The system performs preliminary detection of communication status before proceeding with feeding and printing operations. By detecting communication failures in advance and stopping feeding proactively, the system prevents print defects before they occur, rather than correcting them after the fact. This preliminary action approach resolves the contradiction by anticipating and preventing the harmful effect of print defects.
2Reliability
If feeding is stopped for communication retry, then communication can be reattempted, but printing efficiency is reduced due to overlap printing requirements
Solution Approach 1:
The patent implements a feedback control mechanism where the system continuously monitors communication status and adjusts feeding operations accordingly. When communication succeeds, the system receives positive feedback and resumes feeding without requiring overlap printing, thereby maintaining high production efficiency. The feedback loop ensures that feeding is only stopped when absolutely necessary for communication retry, minimizing impact on productivity.
Solution Approach 2:
The feeding mechanism operates dynamically, switching between stopped and moving states based on real-time communication outcomes. This dynamic operation allows the system to achieve reliable communication while minimizing feeding stoppages, thus maintaining high overall production efficiency without requiring continuous overlap printing that would reduce productivity.
3Productivity
If communication is performed without stopping feeding, then production efficiency is improved, but communication reliability decreases due to potential repeated failures
Solution Approach 1:
The system performs communication operations partially during feeding without complete stops, but implements excessive caution by having the capability to stop feeding when communication fails. This partial action during normal operation maintains high productivity, while the excessive caution (ability to stop and retry) ensures communication reliability when needed, resolving the contradiction between speed and reliability.
Solution Approach 2:
The system performs preliminary communication attempts during feeding operations, and only stops feeding when communication fails. This preliminary action approach allows most communications to succeed during continuous feeding (maintaining productivity), while having a prepared stop-and-retry mechanism for failed cases (ensuring reliability).
