Solution Overview

Problem

Current track and trace systems for pre-printed packaging materials face challenges in verifying the correctness of unique codes on rolls and containers before they are applied in the packaging process, leading to potential errors and production issues due to unknown winding directions and damaged strips.

Innovation Solution

A method for manufacturing pre-printed packaging media involves generating a sequence of unique codes, registering the first and last codes in a computer system, and verifying the sub-series based on the difference between these codes to ensure accuracy within a pre-defined tolerance, thereby managing and controlling the packaging media as a coherent group.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If pre-printed packaging media are marked with unique codes before manufacturing, then tracking and authentication can be performed throughout the supply chain, but verification of code correctness and detection of discontinuities becomes difficult

Engineering Contradiction:

Improvetracking and authentication reliabilityVSAvoidcode verification difficulty

Core Design Contradiction:

ReliabilityVSDifficulty of detecting and measuring

Solution Approach 1:

The system performs preliminary verification of unique codes on packaging media at the point of manufacture or receipt, before the media enter the supply chain. This includes checking code sequence continuity, detecting discontinuities, and validating code formats in advance, thereby ensuring reliability downstream without creating verification difficulties later

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms where verification results of unique codes are immediately fed back to control the packaging process. If discontinuities or errors are detected in code sequences, the system can halt production or flag specific issues, enabling real-time correction and maintaining high tracking reliability

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If rolls of pre-printed media are wound in unknown directions, then manufacturing flexibility is maintained, but verification of winding direction and code sequence becomes complex

Engineering Contradiction:

Improvemanufacturing flexibilityVSAvoidverification system complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Instead of trying to determine winding direction through complex physical inspection, the system inverts the approach by using the unique codes themselves as indicators. The verification system reads codes sequentially and determines winding direction based on code sequence logic, transforming a physical measurement problem into an information processing task that maintains flexibility while reducing verification complexity

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent replaces mechanical or physical methods of determining winding direction with an information-based system that uses code sequence analysis. Optical scanners or readers automatically detect code patterns and infer winding direction, substituting complex mechanical inspection systems with simpler electronic verification processes

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Productivity

If damaged strips occur in pre-printed media, then production continuity is maintained, but detection and localization of damage becomes difficult

Engineering Contradiction:

Improveproduction continuityVSAvoiddamage detection precision

Core Design Contradiction:

ProductivityVSMeasurement precision

Solution Approach 1:

The system performs preliminary inspection of packaging media for damage and code discontinuities at the point of receipt or before production. By detecting damaged strips or missing codes in advance through automated verification systems, the company can isolate and replace only the affected portions, maintaining overall production continuity while precisely locating damage

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The verification system provides immediate feedback on the condition of packaging media, including precise localization of damaged strips or code discontinuities. This feedback enables rapid response to isolate affected areas and replace only necessary components, maintaining high productivity while achieving precise damage detection

Inventive Principle:

Principle #23Feedback

AI summary

A method for manufacturing a group of packaging media includes producing a series of packaging media; generating a sequence of unique codes in a computer system, physically marking the series of packaging media with the unique codes; registering a first unique code marked on a first packaging media in a first end of the series, entering an ordered number of packaging media in the computer system, creating two or more sub-series of packaging media from the series of packaging media based on the ordered number, registering a last unique code marked on a last packaging media in a last end of the sub-series, calculating an expected number of packaging media in the sub-series, and accepting the sub-series if a difference between the expected number and the ordered number is within a pre-defined tolerance, or refusing the sub-series if the difference is outside the pre-defined tolerance.
