Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple image acquisition devices work in a cluster to improve scanning efficiency, then productivity increases, but image synchronization accuracy deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the central control device receives acquisition numbers from multiple image acquisition devices, compares them against expected values based on square wave synchronization signals, and generates verification results. This closed-loop feedback system ensures that even as the number of devices increases, each device's synchronization status is continuously monitored and verified, maintaining synchronization accuracy while enabling cluster operation for improved productivity.
Solution Approach 2:
The patent introduces a central control device as an intermediary that coordinates between multiple image acquisition devices and the main controller. This intermediary receives trigger instructions, generates and distributes square wave synchronization signals, and collects acquisition numbers for verification. The central control device acts as a mediator that manages synchronization across the cluster, allowing multiple devices to work together efficiently while maintaining precise synchronization through centralized coordination.
2Ease of operation
If image acquisition devices operate without synchronization verification to maintain simple operation, then ease of operation is improved, but reliability of scanning results deteriorates
Solution Approach 1:
The patent implements a self-service verification mechanism where the system automatically performs synchronization verification without requiring manual intervention. The central control device automatically receives acquisition numbers from image acquisition devices, compares them against expected values, generates verification results, and sends notifications to the main controller. This automated self-service approach maintains ease of operation while ensuring reliability, as the verification process occurs autonomously without adding operational complexity for the user.
3Manufacturing precision
If synchronization verification is implemented to ensure accurate scanning results, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The patent designs the central control device with multi-functionality, enabling it to perform multiple roles: receiving trigger instructions, generating square wave synchronization signals, distributing signals to multiple image acquisition devices, collecting acquisition numbers, performing verification calculations, and sending notifications. By consolidating these functions in a single multi-functional device rather than adding separate components for each function, the system achieves precise synchronization verification while minimizing the increase in device complexity.
