Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the display device operates in a folded state with full display functionality, then the display area is maximized, but power consumption increases unnecessarily in non-visible regions
Solution Approach 1:
The display device dynamically adjusts its operation mode based on the detected folded state. The control portion receives fold state information from the sensing portion and switches between first operation mode (full display functionality) and second operation mode (reduced functionality in non-visible regions), allowing the system to adapt its power consumption characteristics to the current usage scenario
Solution Approach 2:
The display device applies different operation modes to different regions of the display. In the folded state, the control portion identifies non-visible regions and applies a second operation mode that reduces or suspends display functionality specifically in those regions, while maintaining full functionality in visible regions, thus achieving localized power optimization
2Use of energy by moving object
If the display device maintains full display operation in folded state, then image quality is preserved, but power consumption increases in non-visible regions
Solution Approach 1:
The display device dynamically switches between first operation mode (maintaining full image display quality) and second operation mode (reducing or suspending image display) in non-visible regions based on the detected folded state, allowing power consumption to be reduced without affecting image quality in visible regions
3Use of energy by moving object
If the sensing mechanism continuously monitors fold state, then display optimization is achieved, but device complexity increases
Solution Approach 1:
The sensing portion is designed to detect the folded state of the display device, and this single detection capability enables multiple functions: optimizing power consumption by switching operation modes, adjusting display functionality in different regions, and adapting the device to portable information processor usage scenarios
Solution Approach 2:
The control portion receives fold state information from the sensing portion and uses this feedback to automatically switch between operation modes and adjust display functionality, creating a closed-loop system that optimizes power consumption based on real-time device state without requiring complex manual control mechanisms
