Solution Overview
Problem
Existing banknote transport systems in processing machines face challenges in identifying and analyzing transport errors, making it difficult to determine the location and type of errors that occur during the transport of banknotes.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If light barriers are provided at one or more positions in the transport system to detect the transport of banknotes, then the presence or absence of banknotes can be detected, but it becomes difficult to identify the location and type of transport errors that occur
Solution Approach 1:
The control device stores sensor signals with time indications and object codes before error analysis is needed. This preliminary recording of all transport data allows for efficient post-event error localization and classification without requiring complex real-time analysis mechanisms.
Solution Approach 2:
The patent introduces an intermediary data structure (stored sensor signals with time indications and object codes) that mediates between the simple detection function of light barriers and the complex requirement for error analysis. This intermediary layer enables error localization without modifying the basic sensor functionality.
2Measurement precision
If multiple sensors are used along the transport system to monitor banknotes, then transport can be monitored at multiple positions, but the signals from multiple sensors become difficult to correlate and evaluate for error analysis
Solution Approach 1:
The control device merges signals from multiple sensors by storing them together with common reference data (time indications and object codes). This combining approach allows correlated evaluation of multiple sensor signals without requiring complex synchronization mechanisms, as all signals are already aligned to the same temporal and object reference framework.
Solution Approach 2:
The patent transforms sensor signals by adding time indication and object code parameters to each detection event. This parameter enrichment allows signals from multiple sensors to be correlated and evaluated systematically, converting multiple independent detection streams into a unified dataset suitable for error analysis.
3Difficulty of detecting and measuring
If sensor signals are stored with time indications and object codes for error analysis, then transport errors can be localized and analyzed, but the data storage and processing requirements increase
Solution Approach 1:
The control device extracts and stores only the essential error-relevant information (sensor signals with time indications and object codes) rather than storing complete sensor data streams. This selective extraction reduces storage requirements while maintaining sufficient information for error localization and analysis.
Solution Approach 2:
The system performs preliminary filtering and selection of relevant sensor signals before storage, extracting only those signals that contain error-relevant information. This preliminary processing reduces the quantity of data that needs to be stored and processed, while preserving the capability for comprehensive error analysis.
