Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If display controlling apparatus uses traditional fixed display methods, then device complexity is low, but user convenience and authentication efficiency are poor
Solution Approach 1:
The display apparatus dynamically adjusts display content and positioning based on real-time detection of authenticated person's location and movement. The system transitions from static fixed displays to dynamic adaptive displays that automatically follow and present information to the authenticated person, thereby improving user convenience without requiring complex manual control interfaces
Solution Approach 2:
The system automatically detects the authenticated person's position, determines appropriate display content, and controls display timing without requiring user intervention. The display apparatus serves itself by autonomously managing the display based on detected conditions, reducing the need for complex user operations while maintaining high convenience
2Productivity
If display controlling apparatus implements position-based dynamic display, then user convenience is improved, but device complexity increases
Solution Approach 1:
The system performs preliminary detection and identification of the authenticated person before the actual display operation. By pre-determining the person's location, movement trajectory, and appropriate display content in advance, the system can execute efficient authentication and display control without increasing operational complexity during the actual authentication process
Solution Approach 2:
The display apparatus continuously monitors the authenticated person's position and movement, using this feedback to dynamically adjust display content and timing. This closed-loop feedback mechanism enables efficient authentication by automatically adapting to the person's movements, improving productivity while managing complexity through automated adaptive control
3Productivity
If display controlling apparatus uses automated position estimation, then authentication efficiency is improved, but measurement precision requirements increase
Solution Approach 1:
The system uses partial detection information and estimation methods that do not require complete precise measurement of all parameters. By using key diagnostic features and allowing certain degrees of approximation in position and movement detection, the system achieves efficient authentication without demanding extremely high measurement precision for all parameters
Solution Approach 2:
The system adapts the precision requirements of measurement parameters based on the current authentication context and detected conditions. By dynamically adjusting which parameters are measured and at what precision level, the system maintains high authentication efficiency while managing measurement precision requirements flexibly rather than uniformly
