Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single light sensing unit is provided on the front of the electronic device, then the device structure remains simple, but the ambient light sensing angle is limited and cannot sense light at different spatial positions simultaneously
Solution Approach 1:
The light sensing module is segmented into multiple independent light sensing units (first light sensing unit on the front surface, second light sensing unit on the rear surface). Each unit independently senses ambient light from different spatial directions, thereby increasing the overall sensing angle and adaptability without requiring a single complex sensing element
2Adaptability or versatility
If a single light sensing unit is used, then the device structure is simple, but the adaptability of screen brightness to ambient light is insufficient
Solution Approach 1:
The light sensing function is divided into multiple units positioned at different locations (front and rear surfaces). The control circuit processes signals from both units to determine ambient light conditions more accurately, enabling better screen brightness adaptation to varying light environments from different directions
Solution Approach 2:
The first and second light sensing units are combined into a unified light sensing module that works together with the screen module and control circuit. By merging the sensing capabilities of both units, the system achieves comprehensive ambient light detection and improved brightness control adaptability
