Solution Overview

Problem

Existing container inspection systems in the beverage manufacturing industry face inefficiencies and space constraints due to single-track transport and inspection methods, which can lead to errors and increased costs, especially with the use of space-consuming switches and limited inspection capabilities.

Innovation Solution

A dual-lane transport and inspection system where containers are transported on parallel paths, allowing for independent control of transport units, reduced space requirements, and efficient inspection using image recording devices, with the option for separate drives and guide rails to adapt to different container sizes, enabling cost and space savings by eliminating the need for additional inspection units.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single-track transport system is used for container inspection, then the device complexity is reduced, but the inspection efficiency and productivity decrease

Engineering Contradiction:
Improvetransport system structureVSAvoidinspection efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The transport system is divided into two separate parallel tracks, allowing containers to be transported and inspected simultaneously on both lanes. This segmentation enables the inspection device to process multiple containers in parallel, thereby increasing productivity without significantly increasing overall system complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system transitions from a single-dimensional (single-track) transport to a two-dimensional (dual-lane parallel) transport configuration. This dimensional change allows the inspection device to access and inspect containers from the same stationary position on both lanes, improving inspection efficiency while maintaining manageable device complexity

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Productivity

If a multi-lane transport system is implemented, then inspection efficiency improves, but the space requirements and device complexity increase

Engineering Contradiction:
Improveinspection efficiencyVSAvoidspace requirements
Core Design Contradiction:
ProductivityVSArea of stationary object

Solution Approach 1:

The inspection device is designed as a unified stationary unit that serves both transport lanes simultaneously. By merging the inspection functionality into a single shared device rather than having separate inspection units for each lane, the system achieves high productivity while minimizing space requirements

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The stationary inspection device is designed with universal functionality to inspect containers on both transport lanes from the same position. This multi-functional design eliminates the need for multiple separate inspection units, thereby improving inspection efficiency while reducing the overall space required for the inspection system

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If independent control of transport units is implemented, then operational flexibility and reliability improve, but the device complexity increases

Engineering Contradiction:
Improveoperational flexibilityVSAvoidcontrol system structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The transport units are equipped with independent drives that can be dynamically controlled at different speeds. This dynamic control capability allows each lane to operate autonomously, improving reliability and operational flexibility. The control system manages this independence through modular design, preventing excessive complexity by allowing each lane to be controlled separately rather than requiring a complex centralized control system

Inventive Principle:
Principle #15Dynamics
