Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the application is modified to accept information from external control devices, then the adaptability is improved, but the ease of operation deteriorates
Solution Approach 1:
A driver software module acts as an intermediary between the 3D application and external control devices. The driver includes a modification module that intercepts API calls from the application, converts them into device-specific commands, and transmits them to external devices without requiring application modification. This mediator approach enables adaptability while preserving application simplicity.
Solution Approach 2:
The system architecture is segmented into distinct functional modules: the 3D application layer, the driver software layer with modification module, and the external control device layer. This segmentation allows the application to remain unchanged while the driver handles device-specific adaptations, resolving the contradiction between adaptability and ease of operation.
2Adaptability or versatility
If the application is modified to support external control devices, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The driver software serves as an intermediary that absorbs the complexity of device integration. The modification module within the driver handles all device-specific protocols and communication, keeping the application simple while enabling adaptability to multiple external devices through a unified interface.
Solution Approach 2:
The system uses API call copying and transformation. Instead of modifying the application to support each device, the driver copies the application's standard API calls and transforms them into device-specific commands. This copying approach enables multi-device adaptability without increasing application complexity.
3Ease of operation
If a tracking algorithm is used to modify signals, then the ease of operation is improved, but the loss of information increases
Solution Approach 1:
The tracking algorithm implements continuous feedback by monitoring user actions and device states, then adjusting signal modification in real-time. This feedback mechanism ensures that modifications are reversible and accurate, maintaining information integrity while improving ease of operation through automatic tracking and adjustment.
