Solution Overview

Problem

In automated mailing systems, the production of complete packages with inserts is often hindered by errors, leading to incomplete packages and significant manual effort required for post-production, especially in small print runs, which results in inefficiencies and increased waiting times.

Innovation Solution

The higher-level control device ensures continuous production by immediately detecting and correcting faulty products, allowing for parallel reproduction of missing items and automatic assignment of sub-packages, eliminating the need for manual rework and maintaining constant system output.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual post-production is used to complete incomplete packages, then package completeness is improved, but manual effort and time consumption increase significantly

Engineering Contradiction:
Improvepackage completenessVSAvoidmanual processing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system automatically detects incomplete packages and triggers reproduction of missing products without human intervention. The control device monitors package assembly, identifies deficiencies, and initiates corrective actions autonomously, eliminating the need for manual post-production completion.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements continuous monitoring of package assembly at defined balance points, with detected defects fed back to the control device. This feedback loop enables real-time detection and automatic correction of incomplete packages through immediate reproduction of missing items, replacing manual inspection and completion processes.

Inventive Principle:
Principle #23Feedback

2Reliability

If manual completion of incomplete packages is performed, then package integrity is improved, but productivity decreases due to repeated manual intervention

Engineering Contradiction:
Improvepackage integrityVSAvoidproduction output
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system autonomously handles package completion by automatically reproducing missing products and integrating them into incomplete packages. This self-correcting mechanism maintains package integrity while eliminating manual intervention, thereby preserving production throughput and overall productivity.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The automatic detection and reproduction system operates continuously without interrupting the production flow. Missing products are reproduced and integrated in real-time, ensuring continuous package completion without the stoppages and manual handling that would reduce productivity.

Inventive Principle:
Principle #20Continuity of useful action

3Productivity

If the system stops when target print run is reached, then production control is improved, but correction of remaining defective copies becomes impossible

Engineering Contradiction:
Improveproduction controlVSAvoiddefect correction capability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The control device continuously monitors production status and defect occurrences throughout the print run. This ongoing feedback enables the system to identify and correct defective copies even after the target print run is reached, as the monitoring and correction mechanisms remain active until all products are verified.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs preliminary detection and correction of defects during the production process itself, rather than waiting until the end. By continuously identifying and correcting defective copies as they are produced, the system ensures all products meet quality standards before leaving the production line.

Inventive Principle:
Principle #10Preliminary action

AI summary

The method involves monitoring and regulating integral production of group of printed product packages. The defective printed product is eliminated during the monitoring and regulating processes. The postproduction of printed product corresponding to number of defective printed product is triggered, when subsequent excretion of defective printed products is performed.
