Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authorized personnel perform on-site calibration using test weights, then calibration accuracy and compliance are ensured, but personnel costs and time consumption increase
Solution Approach 1:
The weighing device enables self-calibration by automatically detecting test weights placed on the load receptor and performing calibration procedures without requiring authorized personnel to be physically present. The system uses automated weight detection, position verification, and calibration execution to allow end-users to perform calibrations independently, eliminating the need for on-site visits while maintaining calibration accuracy through automated verification processes.
Solution Approach 2:
The patent replaces the manual mechanical process of authorized personnel physically transporting and handling test weights with an automated electronic system. The weighing device automatically detects test weights using load receptors, identifies their positions and values through electronic evaluation, and executes calibration procedures via software control, substituting the mechanical human operation with an automated electromechanical system.
2Reliability
If authorized personnel perform on-site calibration using test weights, then calibration compliance is ensured, but personnel expenditure increases
Solution Approach 1:
The system enables self-calibration by automatically guiding users through the calibration process, detecting test weights, verifying their positions, and executing calibration procedures without requiring specialized personnel. The automated system maintains compliance through built-in verification logic that ensures calibration procedures are performed correctly, replacing the need for authorized personnel with an automated compliance assurance mechanism.
Solution Approach 2:
The weighing device incorporates feedback mechanisms that automatically verify test weight detection, position validation, and calibration result confirmation. The system provides real-time feedback to users about the calibration status and compliance, automatically adjusting and verifying procedures to ensure regulatory requirements are met, thereby maintaining calibration compliance without specialized personnel oversight.
3Ease of operation
If manual calibration procedures are used, then simplicity of operation is maintained, but productivity decreases
Solution Approach 1:
The patent replaces manual calibration operations with an automated electronic system that detects test weights, determines their positions and values, and executes calibration procedures automatically. This substitution maintains ease of operation by requiring minimal user input (simply placing test weights on the platform) while dramatically improving productivity through automated processing, eliminating the need for manual calculation and verification steps.
Solution Approach 2:
The system performs calibration operations autonomously by automatically detecting test weights, evaluating their positions and values, and executing calibration procedures without requiring skilled operators. This self-service capability maintains operational simplicity for users while significantly increasing calibration throughput and efficiency, as the system can perform multiple calibration operations rapidly without human intervention.

AI summary
In order to reduce the personnel expenditure for calibrating a weighing device, a test weight (12) provided with a localization tag (10) is placed on a load sensor (2) of the weighing device and the weight value thereof is determined. An identifier and the position of the test weight (11) on the load sensor (2) are automatically determined by means of a real-time localization system (9). The weighing device is automatically checked on the basis of the determined identifier and position of the test weight (11) and the determined weight value thereof.
