Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a dedicated system control device is used to determine sample assignment to test devices, then sample assignment accuracy is improved, but device complexity increases
Solution Approach 1:
The patent merges the sample assignment function into the transport controller that is already present in each test device. Instead of having a separate dedicated system control device, the transport controller within each test device determines sample assignment based on transport status information exchanged with other test devices. This integration eliminates the need for additional dedicated control hardware while maintaining assignment accuracy.
Solution Approach 2:
The transport controller, originally designed for transport operations, is given the additional universal function of determining sample assignment. By making the transport controller multi-functional, the system eliminates the need for a separate dedicated control device, thereby reducing overall system complexity while preserving the sample assignment capability.
2Manufacturing precision
If a dedicated system control device is used for sample assignment, then control precision is improved, but device complexity increases
Solution Approach 1:
The control function for sample assignment is merged into the existing transport controller within each test device. The transport controller uses transport status information from itself and other test devices to determine optimal sample assignment, thereby achieving precise control without requiring a separate dedicated control device.
Solution Approach 2:
Each test device's transport controller independently determines sample assignment for itself and other test devices based on exchanged transport status information. This self-service approach eliminates the need for external dedicated control hardware while maintaining precise control over sample assignment decisions.
3Adaptability or versatility
If multiple test devices operate independently with individual control, then operational autonomy is improved, but system coordination efficiency deteriorates
Solution Approach 1:
Test devices exchange transport status information with each other, creating a feedback mechanism that enables coordinated sample assignment. Each transport controller uses this feedback information to make informed assignment decisions that consider the operational state of the entire system, thereby improving coordination efficiency while preserving individual device autonomy.
Solution Approach 2:
The system performs preliminary information exchange about transport status before sample assignment decisions are made. This preliminary action allows each transport controller to anticipate the needs and capabilities of other test devices, enabling more efficient coordinated assignment while maintaining operational independence.
