Value Document Sensor with External Data Carrier for Easy Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sensors for checking value documents require frequent updates and maintenance, involving costly service calls to transfer new software and adaptation data, and replacing defective sensors with the same configuration is inefficient.
Innovation Solution
A sensor design where software and adaptation data are stored temporarily in a volatile memory, loaded from an external data carrier or communication interface, eliminating the need for permanent storage within the sensor, allowing for easy updates and transfers between sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If software and adaptation data are permanently stored in the sensor, then the sensor can operate independently, but updating and replacing sensors requires costly service calls and loses time
Solution Approach 1:
The patent extracts software and adaptation data from permanent storage within the sensor and places them on external removable data carriers. This allows the sensor to be updated by simply replacing the data carrier rather than requiring service calls, directly resolving the contradiction between ease of updating and time loss.
Solution Approach 2:
The patent introduces removable data carriers as an intermediary between the sensor and the updating process. These carriers store software and adaptation data externally, allowing quick exchange without service intervention, thus improving ease of operation while minimizing time loss.
2Ease of manufacture
If software and adaptation data are permanently stored in the sensor, then the sensor has complete functionality, but replacing a defective sensor requires transferring data to the new sensor
Solution Approach 1:
By extracting software and adaptation data from the sensor's permanent storage and placing them on external data carriers, the patent simplifies the replacement process. When a sensor is replaced, the data carrier is simply moved to the new sensor, eliminating complex data transfer procedures and improving ease of manufacture.
Solution Approach 2:
The patent uses removable data carriers that can be copied or reused across multiple sensors. Instead of transferring data from one sensor to another, the same data carrier can be inserted into a replacement sensor, simplifying the process and reducing device complexity.
3Adaptability or versatility
If software and adaptation data are permanently stored in the sensor, then the sensor is self-sufficient, but maintenance involves high costs and service calls
Solution Approach 1:
The patent extracts software and adaptation data from permanent storage and places them on external removable carriers. This allows flexible updates by simply replacing the data carrier, enhancing adaptability while reducing maintenance costs by eliminating service call requirements.
Solution Approach 2:
The patent makes the sensor's software and data dynamic by using removable carriers that can be easily exchanged. This dynamic approach allows the sensor to adapt to different software versions and adaptation data without permanent modifications, improving versatility while reducing maintenance complexity and cost.
Data Source
AI summary
A sensor for checking value documents, an apparatus with the sensor, and a method for operating the sensor. Neither the software that the sensor executes for checking the value documents nor the adaptation data that the sensor employs for checking the value documents are stored permanently in the sensor itself. The sensor is set up for the software as well as the adaptation data to be loaded into the sensor from outside the sensor. The sensor can be employed for checking value documents only when a data carrier is connected to the sensor, and the data carrier has license data stored thereon through which a license for the employment of the software and/or of the adaptation data is supplied to the sensor.
