Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If manual assignment of text/image information to machine states is implemented, then communication clarity improves, but device complexity increases
Solution Approach 1:
The system pre-assigns specific text and image information to various machine states during the programming phase. This preliminary assignment creates a structured database of information associations that enables automatic retrieval and display during operation, eliminating the need for manual information assignment during runtime and improving communication clarity without proportionally increasing operational complexity
Solution Approach 2:
The system creates standardized information templates and data structures that can be reused across multiple machine states. By copying and adapting predefined information formats rather than creating unique information assignments for each state, the system reduces the overall complexity of information management while maintaining clear communication of machine states to operators
2Productivity
If automated recording and display of image information is implemented, then productivity improves, but device complexity increases
Solution Approach 1:
The system automatically detects machine states through sensors and control systems, retrieves pre-assigned image information from memory, and displays it on the user interface. This closed-loop feedback mechanism enables automated recording and display of image information based on actual machine conditions, improving productivity by eliminating manual intervention while the structured information retrieval process minimizes the increase in device complexity
Solution Approach 2:
The machine control system integrates multiple functions including state detection, information retrieval, and image display through a unified control architecture. By making the control system multi-functional rather than adding separate dedicated systems for each function, the patent achieves automated recording and display capabilities while limiting the proportional increase in device complexity
