Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the device uses multiple sensors to detect folding angle and movement, then the adaptability of display orientation control is improved, but the device complexity increases
Solution Approach 1:
The sensor system is segmented into multiple independent sensors (first sensor in first housing, second sensor in second housing) that each detect specific movement parameters. This segmentation allows the system to gather comprehensive spatial information while maintaining modular architecture, resolving the contradiction between adaptability and complexity by distributing sensing functions across separate components.
Solution Approach 2:
The sensors serve multiple functions: detecting folding angle, determining display orientation, and controlling display shape. This multi-functionality reduces the need for separate specialized sensors, thereby improving adaptability without proportionally increasing device complexity.
2Adaptability or versatility
If the device switches between different display configurations based on folding angle, then the versatility of the device is improved, but the control system complexity increases
Solution Approach 1:
The control system dynamically adjusts display configuration based on real-time sensor feedback about folding angle and movement. The processor automatically determines appropriate display orientations and shapes without requiring complex manual control logic, resolving the contradiction by implementing adaptive dynamic control rather than static complex switching mechanisms.
Solution Approach 2:
The system uses feedback from sensors detecting folding angle and housing movement to automatically control display configuration. This feedback mechanism simplifies the control system by using real-time spatial information to determine display settings, avoiding the need for complex pre-programmed switching logic while maintaining high versatility.
3Measurement precision
If the device uses both first and second sensors to obtain movement data, then the measurement precision of spatial orientation is improved, but the energy consumption increases
Solution Approach 1:
Each sensor is positioned locally in its respective housing to detect specific movement characteristics of that housing. This local positioning allows precise measurement of spatial orientation by capturing localized movement data, which when combined provides comprehensive precision information without requiring continuous operation of all sensors at full power, thereby managing energy consumption.
