Solution Overview

Problem

Filling machines in food processing plants face challenges with confusion and incorrect filling due to longer waiting times and multiple production lines producing different products, leading to potential mixing of products and failure to maintain the 'first in, first out' order.

Innovation Solution

A data reading device is integrated into the filling machine to read container data stored on RFID chips or barcodes, controlling the filling process based on this information, ensuring only acceptable products are processed and maintaining the correct order, with the option to connect to a PC network for further data retrieval.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If containers are transported through staging areas with longer waiting times, then productivity is improved by batch processing, but reliability deteriorates due to product mixing and incorrect filling order

Engineering Contradiction:
Improvebatch processing efficiencyVSAvoidfilling order accuracy
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system performs preliminary actions by storing container data (including production time, product type, and sequence information) in RFID tags or barcodes before the filling process. This allows the control system to pre-plan and enforce the correct filling sequence, ensuring reliability even when containers wait in staging areas for batch processing.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback by continuously reading container data via RFID or barcode scanners, comparing the actual filling sequence against the planned sequence, and providing real-time alerts or automatic corrections when deviations occur. This ensures that the 'first in, first out' principle is maintained despite batch processing delays.

Inventive Principle:
Principle #23Feedback

2Productivity

If multiple production lines produce different products simultaneously, then productivity is improved through parallel production, but reliability deteriorates due to product confusion and mixing

Engineering Contradiction:
Improveparallel production capacityVSAvoidproduct identification accuracy
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system segments product identification by assigning unique RFID tags or barcodes to each container with specific product information (type, batch, production line). This segmentation allows the control system to distinguish between different products even when multiple production lines operate simultaneously, preventing product mixing while maintaining parallel production efficiency.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system introduces an intermediary control system that acts as a mediator between multiple production lines and the filling machines. This intermediary reads container data, manages product identification, and coordinates filling operations to ensure that the correct product is filled into the correct container, even when multiple products are being processed in parallel.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If manual labeling methods are used for container identification, then device complexity is reduced, but loss of information increases due to reading errors and data mismanagement

Engineering Contradiction:
Improveidentification system simplicityVSAvoidcontainer data accuracy
Core Design Contradiction:
Device complexityVSLoss of information

Solution Approach 1:

The system replaces manual labeling and reading methods with automated electronic identification using RFID tags or barcodes. RFID tags enable contactless, automatic data retrieval without manual intervention, while barcodes provide a simple visual identification system. This substitution eliminates reading errors and data mismanagement associated with manual methods while keeping the overall system relatively simple and cost-effective.

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