Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If devices are placed in different networks for remote combination testing, then testing flexibility and cost-effectiveness are improved, but communication delay increases and real-time properties deteriorate
Solution Approach 1:
The system performs preliminary actions by executing device models in advance to predict communication delay impacts and prepare compensation strategies. The test information management apparatus proactively monitors communication states and pre-adjusts test parameters to maintain real-time properties despite network delays.
Solution Approach 2:
The test information management apparatus acts as an intermediary between devices in different networks. It receives data from transmission sources, processes information considering communication delay characteristics, and distributes data to transmission destinations, thereby mediating the impact of network delays on real-time testing.
2Extent of automation
If data is transmitted between different networks, then remote testing capability is improved, but communication delay influence increases
Solution Approach 1:
The system dynamically adjusts data distribution strategies based on real-time communication state monitoring. The test information management apparatus changes data transmission parameters, selection criteria, and distribution timing according to current network conditions, making the system adaptable to varying communication delays.
Solution Approach 2:
The system implements feedback mechanisms where the test information management apparatus continuously monitors communication states between devices in different networks and uses this information to adjust data distribution decisions. This closed-loop control enables the system to respond to and compensate for communication delays.
3Measurement precision
If communication state monitoring is implemented, then data distribution accuracy is improved, but system complexity increases
Solution Approach 1:
The test information management apparatus performs multiple functions within a single component: it monitors communication states, executes device models, determines data distribution strategies, and distributes data. This multi-functionality reduces the need for separate specialized components, thereby managing system complexity while achieving accurate data distribution.
