Solution Overview

Problem

Existing tag-label producing apparatuses waste margin portions as they are not effectively utilized, leading to inefficiencies in producing RFID labels with fixed lengths and wasted surplus portions due to predetermined intervals of RFID circuit elements and fixed cutting mechanisms.

Innovation Solution

A tag-label producing apparatus that allocates label length information dynamically, allowing surplus portions to be utilized for producing ordinary labels, thereby optimizing the use of tag tape and reducing waste by adjusting the printing and cutting processes based on allocated label length signals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the cutting mechanism is positioned before the printing portion in the tape feeding direction, then the RFID label production process can be completed, but a non-print section (margin area) is created from the cutting portion to the print start position which is wasted

Engineering Contradiction:
Improvelabel production efficiencyVSAvoidwaste of margin area
Core Design Contradiction:
ProductivityVSLoss of substance

Solution Approach 1:

The patent makes the cutting position dynamic by allowing it to be adjusted based on the actual label length requirements. The cutting position detection means detects the position dynamically, and the cutting mechanism can cut at different positions along the tape, transforming the fixed cutting position into a variable one that adapts to different printing needs, thereby eliminating wasted margin areas.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of cutting position from a fixed value to a variable value that can be adjusted according to the label specifications. By detecting the actual position where cutting should occur and adjusting the cutting mechanism accordingly, the system optimizes the use of tape material and eliminates the non-print margin area waste.

Inventive Principle:
Principle #35Parameter changes

2Ease of manufacture

If RFID circuit elements are arranged with predetermined equal intervals on the tag tape, then the tag-label producing apparatus can operate systematically, but the label length is fixedly determined and surplus portions cannot be utilized

Engineering Contradiction:
Improvesystematic production processVSAvoidlabel length flexibility
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent introduces dynamic adjustability to the cutting position, allowing the system to produce labels of varying lengths from the same tag tape with predetermined RFID circuit element intervals. The cutting position detection means and adjustable cutting mechanism enable the system to adapt to different label length requirements while maintaining the systematic arrangement of RFID elements.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent segments the tag tape at different positions based on detected requirements, allowing flexible creation of labels with different lengths from the same continuous tape. This segmentation approach enables the system to utilize surplus portions of the tape that would otherwise be wasted, while maintaining the predetermined intervals of RFID circuit elements.

Inventive Principle:
Principle #1Segmentation

3Device complexity

If the cutting mechanism is fixed at a predetermined position, then the apparatus structure is simple, but surplus portions of the tag tape are wasted when producing labels with different length requirements

Engineering Contradiction:
Improvecutting mechanism structureVSAvoidwaste of surplus tag tape
Core Design Contradiction:
Device complexityVSLoss of substance

Solution Approach 1:

The patent implements a self-service mechanism where the cutting position detection means automatically detects the optimal cutting position based on the label requirements, and the cutting mechanism automatically adjusts to this detected position. This self-adjusting system eliminates the need for complex manual adjustment mechanisms while maximizing tape utilization and minimizing waste.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent introduces a feedback mechanism where the cutting position detection means continuously monitors the tape position and provides feedback to the cutting mechanism. This feedback loop enables the system to automatically adjust the cutting position to match the actual label length requirements, thereby eliminating waste of surplus tape portions while maintaining operational simplicity.

Inventive Principle:
Principle #23Feedback
