Solution Overview

Problem

Existing storage devices for rod-shaped articles in the tobacco processing industry, such as filter rods, often damage these items due to the need to push them against the weight of already stored articles, leading to stress and potential damage during transverse transport.

Innovation Solution

A storage device with a receiving store and an adjustable working store below it, where rod-shaped articles are introduced through a constriction, allowing them to be gently placed into the working store via gravity, decoupling the insertion force and ensuring the articles are aligned parallel for a compact arrangement, with sensors to adjust storage volume based on fill levels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If rod-shaped articles are pushed into the storage magazine from below against the weight of existing articles, then the articles can be stored in the magazine, but the articles are damaged due to the pushing force against gravity

Engineering Contradiction:
Improvearticle integrityVSAvoidinsertion force
Core Design Contradiction:
ReliabilityVSForce

Solution Approach 1:

The patent inverts the conventional feeding direction by introducing rod-shaped articles into the magazine from above rather than from below. This allows articles to be fed in a direction opposite to gravity, eliminating the need to push articles against their weight and thereby preventing damage to shock-sensitive articles while maintaining reliable storage

Inventive Principle:
Principle #13The other way round (Inversion)

2Quantity of substance

If a large storage volume is provided for rod-shaped articles, then more articles can be stored, but the device complexity increases due to additional adjustment mechanisms

Engineering Contradiction:
Improvestorage capacityVSAvoidadjustment mechanism complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent employs a dynamically adjustable side wall in the working storage unit that can be moved between different positions to vary the storage volume. This dynamic adjustment mechanism allows the storage capacity to be adapted to different operational requirements while maintaining a relatively simple overall device structure through controlled mobility rather than multiple fixed components

Inventive Principle:
Principle #15Dynamics

3Productivity

If the storage volume is made adjustable to optimize space usage, then storage efficiency improves, but the ease of operation decreases due to additional control requirements

Engineering Contradiction:
Improvestorage efficiencyVSAvoidoperational simplicity
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent implements a sensor system that automatically detects the fill level of rod-shaped articles in the magazine and triggers automatic adjustment of the working storage unit volume. This self-service mechanism eliminates the need for manual monitoring and adjustment by operators, maintaining ease of operation while optimizing storage efficiency through automated volume adaptation based on actual storage needs

Inventive Principle:
Principle #25Self-service
