Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple measuring devices are used to determine material properties, then measurement capabilities and versatility are improved, but device complexity and user burden increase
Solution Approach 1:
A controller is introduced as an intermediary between the user and multiple measuring devices. The controller receives measurement requests, autonomously determines suitable devices from available options, and coordinates their operation. This mediator handles the complexity of device selection and coordination, allowing users to benefit from multiple devices without bearing the complexity burden.
Solution Approach 2:
The system enables self-service operation where the measuring devices and controller automatically manage device selection, workload distribution, and measurement coordination without requiring user expertise in each device's operation. The controller autonomously queries device availability, selects appropriate devices, and manages the measurement process.
2Measurement precision
If users manually select and coordinate measuring devices, then measurement precision can be optimized, but time consumption and operational difficulty increase
Solution Approach 1:
The system performs preliminary actions by pre-querying the operational status and availability of all measuring devices before a measurement request is made. The controller maintains updated information about device states, capabilities, and workload, enabling rapid automated selection without requiring time-consuming manual assessment during the measurement process.
Solution Approach 2:
The controller continuously receives feedback from measuring devices regarding their operational status, current workload, and availability. This real-time feedback enables the controller to make informed decisions about device selection and workload distribution, optimizing both measurement precision and response time.
3Reliability
If users are responsible for coordinating device usage, then measurement reliability can be maintained, but ease of operation deteriorates
Solution Approach 1:
The controller serves as a reliable intermediary that manages device coordination, ensuring measurement reliability through systematic device selection and workload management while completely shielding users from coordination complexities. The controller handles device state monitoring, selection, and coordination autonomously.
Solution Approach 2:
The measuring devices operate in a self-service manner where they automatically report their status to the controller and receive assignment instructions without user intervention. This maintains reliable operation through automated status monitoring and coordination while maximizing user convenience.

AI summary
A method for controlling a system having measuring devices includes receiving a request to determine a desired measured value by a controller of the system, creating, by the controller, a proposal as to which of the measuring devices is suitable for determining the specific measured value, and outputting the established proposal to a user of the system by the controller. A system is disclosed including the measuring devices.
