Solution Overview

Problem

Existing systems for producing mixed containers of different beverage types require large storage and picking areas, generate packaging waste, and are prone to errors due to mismatched container labeling or missing containers, leading to incorrect fillings.

Innovation Solution

A filling device with a main filler for a primary component and a secondary filler that adjusts based on container properties detected by an optical reader, allowing flexible production of mixed containers without pre-sorting, combined with a system for immediate packaging into mixed bundles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If containers are pre-sorted and stored in large batches before filling, then the filling process can be simplified, but storage requirements increase and packaging waste is generated

Engineering Contradiction:
Improvefilling process simplicityVSAvoidstorage area
Core Design Contradiction:
Ease of manufactureVSArea of stationary object

Solution Approach 1:

The system performs preliminary identification of container types and product requirements using optical readers and sensors before the filling process. This allows the filling device to be pre-configured for each specific container type, eliminating the need for large-scale pre-sorting and storage while maintaining filling simplicity and accuracy.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The filling device automatically identifies and adapts to different container types through integrated sensors and optical readers. The system self-configures its filling parameters based on detected container properties, eliminating the need for manual pre-sorting and reducing storage requirements while maintaining ease of operation.

Inventive Principle:
Principle #25Self-service

2Manufacturing precision

If containers are pre-sorted by type before filling, then filling accuracy can be improved, but the system becomes more complex and error-prone due to labeling mismatches

Engineering Contradiction:
Improvefilling accuracyVSAvoidpre-sorting system complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The system replaces complex mechanical pre-sorting mechanisms with optical and sensor-based detection systems. Optical readers and sensors automatically identify container types and properties, eliminating the need for mechanical sorting while improving accuracy and reducing complexity through automated recognition and adaptation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The filling device incorporates feedback mechanisms through optical readers and sensors that continuously monitor container properties and adjust filling parameters in real-time. This closed-loop control ensures high filling accuracy without requiring complex pre-sorting systems, as the system adapts dynamically to each container type.

Inventive Principle:
Principle #23Feedback

3Ease of operation

If containers are fed to the filler in a fixed order matching labels, then the filling process is straightforward, but errors occur when containers are missing or mislabeled

Engineering Contradiction:
Improvefilling operation simplicityVSAvoidfilling reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system incorporates optical readers and sensors that provide real-time feedback on container identification and properties. This feedback mechanism allows the filling device to verify container match with product requirements and adjust operations accordingly, maintaining simplicity while significantly improving reliability by detecting and responding to missing or mislabeled containers.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The filling system transitions from a static, fixed-order operation to a dynamic process that adapts to each container's actual properties. The system dynamically adjusts filling parameters and operations based on real-time detection of container type, size, and other properties, ensuring reliable operation regardless of container ordering or labeling status.

Inventive Principle:
Principle #15Dynamics
