Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a transparent display device transmits light incident onto its back surface directly to the user's eye to maintain transparency, then the user can see objects beyond the back surface, but color noise appears from the back surface causing decreased visibility and recognition of displayed information
Solution Approach 1:
The patent implements dynamic control of the transparent display device's transmittance characteristics. The device can switch between different transmittance states (first transmittance and second transmittance) based on environmental conditions detected by sensors. This dynamic adjustment allows the device to optimize the balance between maintaining transparency and ensuring visibility of displayed information under varying lighting conditions.
Solution Approach 2:
The patent changes the optical parameters of the transparent display device by adjusting transmittance characteristics. By controlling the amount of light transmitted through the device and compensating for color noise from the back surface, the system modifies key parameters (transmittance, color balance) to resolve the contradiction between transparency and information visibility.
2Loss of information
If the transparent display device increases brightness of displayed information to overcome background interference, then recognition of information improves, but power consumption increases
Solution Approach 1:
The patent implements dynamic brightness adjustment based on environmental light conditions detected by sensors. The display device adapts its brightness level and transmittance characteristics in real-time, increasing brightness only when necessary to overcome background interference, thereby optimizing the balance between information recognition and power consumption.
Solution Approach 2:
The system uses sensors to detect environmental light conditions and feeds this information back to the control mechanism. Based on this feedback, the device automatically adjusts brightness and transmittance parameters, ensuring optimal information recognition while minimizing unnecessary power consumption in varying environmental conditions.
3Loss of information
If the transparent display device adjusts transmittance to minimize color noise from the back surface, then visibility of displayed information improves, but the transparency effect is reduced
Solution Approach 1:
The patent employs dynamic adjustment of transmittance characteristics, allowing the device to switch between different operational states. In some conditions, it maintains high transparency; in others, it adjusts to minimize color noise and maximize visibility of displayed information, thus dynamically optimizing the transparency effect based on environmental factors.
Solution Approach 2:
The system modifies optical parameters including transmittance and color balance to resolve the contradiction. By controlling light transmission characteristics and compensating for color noise from the back surface, the device adjusts parameters to maintain transparency effect while ensuring visibility of displayed information when necessary.
