Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual inspection process is used, then device complexity is reduced, but productivity is low and inspection accuracy is compromised
Solution Approach 1:
The inspection circuit is segmented into multiple independent pathway switching circuits, each responsible for connecting specific inspection devices to test terminals. This modular segmentation allows automated inspection functionality to be added without creating a monolithic complex system, as each segment can be independently controlled and maintained.
Solution Approach 2:
The pathway switching circuits serve multiple functions: they route inspection signals from different inspection devices to appropriate test terminals, enable automated switching between inspection modes, and provide a unified interface for both manual and automated inspection operations. This multi-functionality reduces the need for separate dedicated circuits for each inspection type.
2Extent of automation
If automated inspection is implemented, then productivity increases, but device complexity increases
Solution Approach 1:
The pathway switching circuits incorporate dynamic switching capabilities that allow the inspection circuit to automatically reconfigure connections based on inspection requirements. The switching circuits can dynamically connect different inspection devices to test terminals under test control, enabling automated inspection sequences without requiring a fixed complex wiring arrangement.
Solution Approach 2:
The pathway switching circuits act as intermediaries between the inspection devices and test terminals, mediating the connection and signal flow. This intermediary layer simplifies the overall system architecture by providing a controlled interface that manages the complexity of automated switching, rather than directly connecting all devices to all terminals.
3Measurement precision
If multiple inspection devices are connected, then measurement precision improves, but device complexity increases
Solution Approach 1:
Each inspection device is connected through its own dedicated pathway switching circuit segment, which segments the complex multi-device connection into manageable independent paths. This segmentation allows multiple inspection devices to operate simultaneously with high measurement precision while the overall complexity is managed through modular organization of the switching circuits.
