Solution Overview

Problem

The manufacturing process for smoking articles, such as cigarettes, often results in defective filter elements due to missing, misoriented, or ruptured objects within the filter rods, leading to quality control issues and reduced yield.

Innovation Solution

A system and method that includes an inspection device with sensors to analyze smoking articles along a transport path, positioned between manufacturing and packaging equipment, allowing for detection and removal of defective filter elements before packaging, utilizing a transport device to convey cigarettes individually through an inspection zone where sensors, like density or near-infrared sensors, assess the presence and condition of objects within the filter elements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If automated object insertion is used in filter rod manufacturing, then production efficiency is improved, but the rate of defective filter elements increases due to missing, misoriented, or ruptured objects

Engineering Contradiction:
Improveproduction efficiencyVSAvoiddefect rate of filter elements
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The inspection device performs preliminary detection of defective filter elements during the transport phase, before packaging occurs. This allows defective items to be identified and removed in advance, preventing them from reaching consumers while maintaining the automated production flow.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The inspection device provides feedback about the quality of filter elements to the packaging system. Based on this feedback, defective items can be sorted and removed, while quality items proceed to packaging, creating a closed-loop quality control system that maintains high productivity.

Inventive Principle:
Principle #23Feedback

2Reliability

If inspection is performed immediately after manufacturing, then defect detection is possible, but the complexity of the manufacturing process increases

Engineering Contradiction:
Improvedefect detection capabilityVSAvoidmanufacturing process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The manufacturing process is segmented into distinct phases: manufacturing, transport/inspection, and packaging. The inspection device is integrated into the transport phase, separating inspection from manufacturing operations. This segmentation reduces the complexity of the manufacturing process itself while maintaining effective defect detection.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The transport system acts as an intermediary between manufacturing and packaging, providing a dedicated space and time for inspection. This intermediary role allows inspection to occur without directly complicating the manufacturing or packaging processes, maintaining process simplicity while achieving reliability.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If defective filter elements are removed early in the process, then yield is improved, but the time required for inspection increases

Engineering Contradiction:
Improvemanufacturing yieldVSAvoidinspection time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The inspection device operates continuously during the transport phase, inspecting filter elements as they move through the transport system. This continuous inspection approach maintains productivity by eliminating idle time while effectively detecting and removing defective items, thereby improving yield without significant time loss.

Inventive Principle:
Principle #20Continuity of useful action
