Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated recording and analysis of process variables is implemented, then productivity and efficiency are improved, but device complexity increases
Solution Approach 1:
The system is divided into distinct functional modules: recording devices for data collection, auditor devices for analysis and event detection, report generators for documentation, and signing devices for authentication. Each module performs a specific function, allowing the complex documentation task to be broken down into manageable segments that can be independently implemented and maintained.
Solution Approach 2:
The auditor device acts as an intermediary between the recording devices and the report generator. It receives process variable data, analyzes it for triggering events, and only forwards relevant information to the report generator. This intermediary layer simplifies the overall system by filtering and preprocessing data, reducing the complexity of direct connections between all components.
2Loss of time
If manual monitoring and documentation of process variables is used, then device complexity is reduced, but loss of time and productivity decrease
Solution Approach 1:
The system performs self-service through automated recording, analysis, and documentation functions. Recording devices automatically capture process variables, auditor devices autonomously analyze data and detect triggering events, and report generators automatically create documentation. This eliminates the need for manual monitoring and documentation, significantly reducing time loss while the modular architecture keeps complexity manageable.
Solution Approach 2:
Manual mechanical processes of monitoring and documentation are replaced with electronic and automated systems. Sensors and recording devices replace manual measurement tools, automated analysis replaces human inspection, and electronic report generation replaces manual paperwork. This substitution dramatically reduces time consumption while the structured electronic system manages complexity through standardization.
3Reliability
If electronic signatures are implemented for legal compliance, then reliability of documentation is improved, but device complexity and operational complexity increase
Solution Approach 1:
Signing devices are pre-configured with authentication credentials and signing algorithms. The system establishes predetermined rules for which triggering events require signatures and which signing devices should be used. This preliminary setup ensures legal compliance is automatically enforced without requiring complex real-time decisions during operation, maintaining simplicity while ensuring reliability.
Solution Approach 2:
The system changes the state of documentation from unsigned to signed, adding a verification parameter that enhances reliability. By implementing electronic signatures as an additional parameter in the documentation process, the system legally secures records without fundamentally altering the core operational flow. The signature parameter is automatically added by the signing device based on predefined conditions.
4Measurement precision
If centralized processing of process variables is implemented, then measurement precision and detection capability are improved, but device complexity and loss of information increase
Solution Approach 1:
The auditor device extracts only the essential information from the complete set of process variables - specifically, triggering events that meet predefined criteria. Instead of transmitting all raw data, the system extracts and forwards only relevant event information to the report generator. This extraction approach maintains high detection accuracy by focusing on critical events while reducing data transmission overhead and preventing information loss.
Solution Approach 2:
The system performs partial analysis by focusing on specific triggering events rather than comprehensively processing all possible data variations. The auditor device applies analysis rules that identify only the most significant deviations and events, performing sufficient analysis to ensure accurate detection without the excessive processing that would generate unnecessary data transmission. This partial action approach balances precision with efficiency.

AI summary
The invention relates to a system and a method for the legally compliant documentation of health- and safety-relevant process events in a food processing plant. The system comprises a workstation, a data acquisition unit, an auditor unit, a report generator, and a signature unit. The data acquisition unit is assigned to the workstation and configured to automatically record plant-related process variables. The auditor unit, on the other hand, is configured to analyze the recorded process variables and detect a triggering event. Furthermore, the auditor unit is capable of generating a first data record containing at least one of the recorded process variables and/or information about the triggering event. The report generator is configured to determine a signature unit responsible for the first data record.Furthermore, the report generator can create a request record that includes a signature request and at least part of the first record. This request record can be transmitted to the responsible signing authority. The signing authority is configured to generate a response record that includes an electronic signature covering at least part of the request record.
