Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a display activates its backlight to operate in dynamic mode, then visibility and image quality are improved, but power consumption increases significantly
Solution Approach 1:
The display dynamically switches between two operational modes: dynamic mode where the backlight is activated for high visibility, and semi-static mode where the backlight remains off to conserve power. This dynamic switching allows the display to adapt its power consumption and visibility characteristics based on operational requirements, resolving the contradiction between maintaining high visibility and reducing power consumption.
Solution Approach 2:
The display changes its operational parameters by switching between different transparency states of the display layers. In dynamic mode, the display parameters are configured for high visibility with backlight activation. In semi-static mode, the parameters are adjusted to maintain visibility through transparency without activating the power-intensive backlight, thus changing the operational parameters to resolve the power consumption versus visibility contradiction.
2Use of energy by moving object
If a display switches from dynamic mode to semi-static mode, then power consumption is reduced, but switching speed and responsiveness may be compromised
Solution Approach 1:
The display system prepares for mode switching by pre-configuring the transparency states of the display layers. Before transitioning to semi-static mode, the display ensures that the transparency mechanism is ready to maintain visibility without backlight activation. This preliminary preparation minimizes the transition time and maintains switching speed while achieving power reduction.
3Use of energy by moving object
If a display uses transparent displays with electronically controlled pixel transparency, then energy efficiency is improved, but device complexity increases
Solution Approach 1:
The transparent display with electronically controlled pixel transparency serves multiple functions: it acts as both the display medium and the transparency control mechanism. This multi-functional design eliminates the need for separate transparency control components, thereby reducing overall device complexity while maintaining energy efficiency benefits.
