Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing electronic devices are used without automatic sensing capability, then device simplicity is maintained, but user safety and operational convenience deteriorate due to lack of automatic state detection and prompt information
Solution Approach 1:
The sensing system is divided into two distinct sensing groups: a first sensing group that detects user entry/exit states, and a second sensing group that detects object states. This segmentation allows each group to specialize in specific detection tasks, improving overall reliability while organizing complexity into manageable modular components
Solution Approach 2:
The system performs preliminary sensing actions by detecting user states before actual space operations occur. The first sensing group identifies user entry/exit states in advance, allowing the system to proactively prepare and display prompt information before the user needs to manually inspect or operate controls
2Ease of operation
If manual inspection steps are required for space operations, then device complexity is reduced, but user convenience and operational efficiency deteriorate
Solution Approach 1:
The system implements a feedback loop where the first sensing group continuously monitors user states, the second sensing group monitors object states, and the display device provides real-time prompt information back to the user. This automated feedback mechanism eliminates manual inspection steps and significantly improves ease of operation
Solution Approach 2:
The sensing system performs self-service by automatically detecting both user states and object states without requiring manual intervention. The system autonomously processes sensing data and generates appropriate prompt information, freeing the user from time-consuming manual inspection tasks
3Loss of information
If prompt information is not displayed based on user state, then device complexity is minimized, but information completeness and user awareness deteriorate
Solution Approach 1:
The display device provides localized, context-specific prompt information based on the detected user state and object state. Rather than displaying all possible information uniformly, the system tailors the information display to the specific situation, improving information completeness while managing processing complexity through selective information presentation
